1 INTRODUCTION

Explain that

bull This short training programme is about oily water

bull It is in two parts This part is about where oily water comes from how to minimise its quantity and how to control its content so that the separator and oil content monitor are able to work properly Part 2 covers how the separator and oil content monitor work how to operate and maintain them simple security precautions and an outline of the new generation of separators

bull You will show them a video lasting about 15 minutes

bull You will then lead a discussion about the points raised in the video The main objective of this discussion is to identify and agree ways of handling oily water better on your ship Stress that you want their ideas and suggestions

Remind the group that the discharge of oily water whether through the separator or to shore based facilities is strictly controlled by internationally agreed regulations and it is inspected by port state

authorities The limit for discharge at sea is 15ppm Iparts per million] and the ship must be en route

during discharge

Ask them if they know what 15ppm means It is roughLy a coffee cup of oiL in 20m3 of water

2 THE VIDEO

3 POINTS FROM THE VIDEO

Ask the group what they thought were the important points from the video In summary these are

bull There are many sources of oily water - such as Leaks spills overfLows and condensation

bull Good housekeeping can reduce the quantity of oily water coming from many of these sources A leak that drips every second can put 30 or 40 litres into the bilges in a day

bull Cleaning is a particular issue

bull Controlling the content as well as the quantity of the oily water that reaches the bilges is important If it contains too much oiL t he separator may struggLe to cope with it If it contains impurities such as soot the OCM may not work properly

4 SOURCES - LEAKS ETC

bull Ask the group for suggestions about how to reduce the amount of oily water from leaks spills and overflows

bull Check that they understand and are following the procedures for handling items contaminated with oil - filters oiLy rags and so on Ask for any ideas about how to do this better

bull Stress the importance of keeping as much oil as possible out of the bilges by for example carefully emptying drip trays

bull Add any points for improvement which the group have not suggested

9

ENGINE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATORS VIDEOTEL PRODUCTIONS

5 SOURCES - CLEANING

Discuss and identify improvements in the procedures for the following cleaning tasks

bull Keeping bilges and holding tanks as clean as possible

bull Preventing emulsifiers getting into the bilge water

bull Clean ing the air cooler in the charge air receiver

bull Disposing of gas oi l used for cleaning

bull Handling water contaminated with soot from pressure wash ing the waste heat recovery unit in the fu nnel while in port

Explain that

bull PART 2 of this short training programme covers how t he separator and OeM work how to operate and ma inta in them including tackling faults simple security precautions and an outline of the new generation of separators

bull As in PART 1 you will show them a video lasting about 15 minutes followed by a discussion about the points raised in the video The main objective of this discussion is to identify and agree ways of handling oily water better on your ship Stress that you want their ideas and suggestions

2 THE VIDEO

3 HOW THE SEPARATOR AND OIL CONTENT MONITOR WORK

Check that those taking part understand the principles of how the separator and OCM work Answer any

questions they may have Points to stress are

bull Separation starts in the holding tank Because oil and water have a different specific gravity the static mixture of the two liqu ids in the tank will separate with oil rising to the top which from there can be drawn off into a waste oil tank This lowers the concentration of oil in the water towards the bottom of the tank making it easier for the separator to deal with

bull The present generation of separators contain two stages

4 OPERATION OF THE SEPARATOR

The details to cover in th is secti on w ill obvi ou sly depend on the make and mode l of the separator on your sh ip Find out wh ether the group ever experience any probLem s when running the equ ipment Ask for any suggesti ons they may have for improvements

You may wish to stress the following general points which were covered in the video

bull It is good practice to put the manufacturers operating instructions in an easily visible position near the separator Encourage those who operate the equipment to check the instructions even if they have used it before Sometimes even experienced operators can overlook something important

bull At the end of each cycle whoever is operating the separator should back-flush the equipment with clean water This cleans the filters in Stage 2 and removes any remaining oil from Stage 1 The separator should be Left full of clean water so that it is ready for the next time it is used

bull At the beginning of each separat ion cycle it is important to zero test the oeM with clean water

bull At the beginning and end of each cycle it is essential to check the ship s exact posit ion as this information must be entered in the Oil Record Book

bull On many ships [yours1 there is a float in the bilge ho lding tank wh ich will stop the separator running before the concentration of oil in the water becomes too great for it to cope with If this is not the case on your sh ip stress that the operator should estimate the amount of pumpable water in the system so that it can be shut down before the separator is flooded with concentrated oiL It is not acceptable pract ice to run the equipme nt until the alarm sounds

Explain and discuss any standing orders on your ship which are additional to the procedures called for in the statutory regulations

15

ENG INE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATO RS VIDEOTEL PRODUCTIONS

5 MAINTENANCE

Discuss the PMS for your separator with the group

bull Check that they understand the important points which it covers

bull Find out whether they have any problems maintaining the equipment or ideas for improvement

bull Explain how you verify that maintenance schedules are being followed

bull Stress the importance of keeping sufficient spares on board

Explain the key points from the fault list for your separator Stress that when faults occur

bull They must stop the separator running as soon as the fault deveLops rather than waiting until they have identified the problem There must never be any risk that water with an oil content above the 15 ppm limit could be discharged overboard

bull They must avoid any temptation to break or bend the rules If a problem arises which can onLy be solved by doing something illegal that is an issue for the shore office to sort out

6 SECURITY

The video highlighted the use of

bull White boxes These prevent anyone tampering with the OCM

bull Seals on valves and flanges in the engine room These ensure that no one can interfere with any pipe work containing oil or oily wastes Some seals are pLastic so that they can be removed quickLy in an emergency Others are chains secured by padLocks The numbers of plastic seals are recorded in the engine room Logbooks and the Chief Engineer keeps the keys to any padlocks

Discuss with the group the steps taken on your ship to protect the security of the equipment for handling oily water

16

ENGINE ROOM WASTE MANAGEMENT OILYWATER AND SEPARATORS VIDEOTEL PRODUCTIONS

7 THE NEW GENERATION OF SEPARATORS

As the student pointed out to the engineer in the video the current generation of separators have some

important disadvantages and limitations They cope badly with dirt soot emulsifiers and oil at too high a concentration Rough sea conditions lower the efficiency of separation For these reasons it is often difficult for even the most experienced engineers to make them work properly

That is why the IMO has introduced a revised set of guidelines and specifications for separators These

are set out in M EPCl 07[49]

MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committee s 107th

resolution passed at their 49th session The full title of the resolution is

Revised guidelines and specifications for pollut ion prevention equipment for machinery spaces of ships

In addition to the usual introduction explanation of the background and definitions the resolution contains

bull Techn icaL specifications

bull Specifications for type approvaL testing of poLlut ion prevention equipment

bull Installation requirements

17

ENGINE ROOM WASTE MANAGEMENT OI LY WATER AND SEPARATORS VIDEOTEL PRODUCTI ONS

These new requirements apply to

bull Installations fitted to ships the keel of which are laid or wh ich are at a similar stage of construction on or after 1 January 2005 and

bull To new installations fitted on or after 1 January 2005 to ships the keel of wh ich were laid or wh ich were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable

The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph

It should be understood that a 15ppm Bilge Separator must be capabLe of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oiL of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emuLsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emuls ify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oiL from the emulsion to produce an effluent w ith an oil content not exceeding 15ppm

Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based

3 POINTS FROM THE VIDEO

Ask the group what they thought were the important points from the video In summary these are

bull There are many sources of oily water - such as Leaks spills overfLows and condensation

bull Good housekeeping can reduce the quantity of oily water coming from many of these sources A leak that drips every second can put 30 or 40 litres into the bilges in a day

bull Cleaning is a particular issue

bull Controlling the content as well as the quantity of the oily water that reaches the bilges is important If it contains too much oiL t he separator may struggLe to cope with it If it contains impurities such as soot the OCM may not work properly

4 SOURCES - LEAKS ETC

bull Ask the group for suggestions about how to reduce the amount of oily water from leaks spills and overflows

bull Check that they understand and are following the procedures for handling items contaminated with oil - filters oiLy rags and so on Ask for any ideas about how to do this better

bull Stress the importance of keeping as much oil as possible out of the bilges by for example carefully emptying drip trays

bull Add any points for improvement which the group have not suggested

3 HOW THE SEPARATOR AND OIL CONTENT MONITOR WORK

Check that those taking part understand the principles of how the separator and OCM work Answer any

questions they may have Points to stress are

bull Separation starts in the holding tank Because oil and water have a different specific gravity the static mixture of the two liqu ids in the tank will separate with oil rising to the top which from there can be drawn off into a waste oil tank This lowers the concentration of oil in the water towards the bottom of the tank making it easier for the separator to deal with

bull The present generation of separators contain two stages

You may wish to stress the following general points which were covered in the video

bull It is good practice to put the manufacturers operating instructions in an easily visible position near the separator Encourage those who operate the equipment to check the instructions even if they have used it before Sometimes even experienced operators can overlook something important

bull At the end of each cycle whoever is operating the separator should back-flush the equipment with clean water This cleans the filters in Stage 2 and removes any remaining oil from Stage 1 The separator should be Left full of clean water so that it is ready for the next time it is used

bull Find out whether they have any problems maintaining the equipment or ideas for improvement

bull Explain how you verify that maintenance schedules are being followed

bull Stress the importance of keeping sufficient spares on board

Explain the key points from the fault list for your separator Stress that when faults occur

bull They must stop the separator running as soon as the fault deveLops rather than waiting until they have identified the problem There must never be any risk that water with an oil content above the 15 ppm limit could be discharged overboard

bull They must avoid any temptation to break or bend the rules If a problem arises which can onLy be solved by doing something illegal that is an issue for the shore office to sort out

6 SECURITY

The video highlighted the use of

bull White boxes These prevent anyone tampering with the OCM

bull Seals on valves and flanges in the engine room These ensure that no one can interfere with any pipe work containing oil or oily wastes Some seals are pLastic so that they can be removed quickLy in an emergency Others are chains secured by padLocks The numbers of plastic seals are recorded in the engine room Logbooks and the Chief Engineer keeps the keys to any padlocks

Discuss with the group the steps taken on your ship to protect the security of the equipment for handling oily water

7 THE NEW GENERATION OF SEPARATORS

As the student pointed out to the engineer in the video the current generation of separators have some

important disadvantages and limitations They cope badly with dirt soot emulsifiers and oil at too high a concentration Rough sea conditions lower the efficiency of separation For these reasons it is often difficult for even the most experienced engineers to make them work properly

That is why the IMO has introduced a revised set of guidelines and specifications for separators These

are set out in M EPCl 07[49]

MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committee s 107th

resolution passed at their 49th session The full title of the resolution is

Revised guidelines and specifications for pollut ion prevention equipment for machinery spaces of ships

In addition to the usual introduction explanation of the background and definitions the resolution contains

bull Techn icaL specifications

bull Specifications for type approvaL testing of poLlut ion prevention equipment

bull Installation requirements

17

ENGINE ROOM WASTE MANAGEMENT OI LY WATER AND SEPARATORS VIDEOTEL PRODUCTI ONS

These new requirements apply to

bull Installations fitted to ships the keel of which are laid or wh ich are at a similar stage of construction on or after 1 January 2005 and

bull To new installations fitted on or after 1 January 2005 to ships the keel of wh ich were laid or wh ich were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable

The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph

It should be understood that a 15ppm Bilge Separator must be capabLe of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oiL of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emuLsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emuls ify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oiL from the emulsion to produce an effluent w ith an oil content not exceeding 15ppm

Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based

THE ENGINE ROOM WASTE MANAGEMENT SERIES

This training programme on Oily Water and Separators is one of a series of four covering different

aspects of engine room waste management The other three cover The Oil Record Book Sewage and

Waste Water Treatment and Sludge and the Incinerator respectively

Each of the four programmes consists of a video and an accompanying guide

TARGET AUDIENCE AND FORMAT

The programme is designed for all engine room personnel It is in two parts each of which is led by a

senior engineer officer Each part begins with a brief introduction The group then watch a video which lasts about fifteen minutes They then discuss the points raised in the video and relate these to the

particular circumstances of their own ship

OBJECTIVES

Those taking part in the training programme will

bull Identify typical sources of oily water

bull Know how to minimise the amount of oily water reaching the bilges and control its content so that the oily water separator (OWSI and oil content monitor [OeMI are able to work properly

bull Understand the working principles of the OWS and the OeM

bull Understand important features of operating and maintaining the OWS including some simple security precautions

bull Learn about the new generation of separators designed to meet the standards specified in MEPC107(49]

MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committees 1 071h resolution passed at their 49 lh session The full title of the resolution is Revised guidelines and spec ifi cations for pollution prevention equipment for machinery spaces of ships

In addition to the usual introduction explanation of the background and definitions the resolution contains

bull Technical specifications

bull Specifications for type approval testing of pollution prevention equipment

bull Installation requirements

bull Relate the issues covered in the programme to their own ship

THE PROGRAMME

bull PART 1 covers where oily water comes from how to m ini mise the quantity reaching the bilges and how to control the content of the water so that the OWS and the OeM are able to function correctly

bull PART 2 covers how the separator and the OeM work how to operate and maintain them simple security precautions and an outline of the new generation of separators

Each part of the programme is divided into sections If you don t have time to run all of either part you

can run some sections separately For example you could discuss operating the separator in one short

training session and maintaining it in another If you do show the video in the first session and dont

leave too much of a gap between sessions

THE VIDEO

The video shows a conversation between an experienced engineer and a student who is nearing the end

of her university degree in mechanical engineering and is considering a career at sea The experienced

engineer explains and discusses why it is important to handle oily water properly and how that is done

The video is in two parts each lasting approximately 15 minutes

bull Learn about the new generation of separators designed to meet the standards specified in MEPC107(49]

MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committees 1 071h resolution passed at their 49 lh session The full title of the resolution is Revised guidelines and spec ifi cations for pollution prevention equipment for machinery spaces of ships

In addition to the usual introduction explanation of the background and definitions the resolution contains

bull Technical specifications

bull Specifications for type approval testing of pollution prevention equipment

bull Installation requirements

bull Relate the issues covered in the programme to their own ship

THE PROGRAMME

bull PART 1 covers where oily water comes from how to m ini mise the quantity reaching the bilges and how to control the content of the water so that the OWS and the OeM are able to function correctly

bull PART 2 covers how the separator and the OeM work how to operate and maintain them simple security precautions and an outline of the new generation of separators

Each part of the programme is divided into sections If you don t have time to run all of either part you

can run some sections separately For example you could discuss operating the separator in one short

training session and maintaining it in another If you do show the video in the first session and dont

leave too much of a gap between sessions

THE VIDEO

The video shows a conversation between an experienced engineer and a student who is nearing the end

of her university degree in mechanical engineering and is considering a career at sea The experienced

engineer explains and discusses why it is important to handle oily water properly and how that is done

1 INTRODUCTION

Explain that

bull This short training programme is about oily water

bull It is in two parts This part is about where oily water comes from how to minimise its quantity and how to control its content so that the separator and oil content monitor are able to work properly Part 2 covers how the separator and oil content monitor work how to operate and maintain them simple security precautions and an outline of the new generation of separators

bull You will show them a video lasting about 15 minutes

bull You will then lead a discussion about the points raised in the video The main objective of this discussion is to identify and agree ways of handling oily water better on your ship Stress that you want their ideas and suggestions

Remind the group that the discharge of oily water whether through the separator or to shore based facilities is strictly controlled by internationally agreed regulations and it is inspected by port state

authorities The limit for discharge at sea is 15ppm Iparts per million] and the ship must be en route

during discharge

Ask them if they know what 15ppm means It is roughLy a coffee cup of oiL in 20m3 of water

ENGINE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATORS VIDEOTEL PRODUCTIONS

3 POINTS FROM THE VIDEO

Ask the group what they thought were the important points from the video In summary these are

bull There are many sources of oily water - such as Leaks spills overfLows and condensation

bull Good housekeeping can reduce the quantity of oily water coming from many of these sources A leak that drips every second can put 30 or 40 litres into the bilges in a day

bull Cleaning is a particular issue

bull Controlling the content as well as the quantity of the oily water that reaches the bilges is important If it contains too much oiL t he separator may struggLe to cope with it If it contains impurities such as soot the OCM may not work properly

4 SOURCES - LEAKS ETC

bull Ask the group for suggestions about how to reduce the amount of oily water from leaks spills and overflows

bull Check that they understand and are following the procedures for handling items contaminated with oil - filters oiLy rags and so on Ask for any ideas about how to do this better

bull Stress the importance of keeping as much oil as possible out of the bilges by for example carefully emptying drip trays

bull Add any points for improvement which the group have not suggested

9

ENGINE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATORS VIDEOTEL PRODUCTIONS

5 SOURCES - CLEANING

Discuss and identify improvements in the procedures for the following cleaning tasks

bull Keeping bilges and holding tanks as clean as possible

bull Preventing emulsifiers getting into the bilge water

bull Clean ing the air cooler in the charge air receiver

bull Disposing of gas oi l used for cleaning

bull Handling water contaminated with soot from pressure wash ing the waste heat recovery unit in the fu nnel while in port

ENGINE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATORS VIDEOTEL PRODUCTIONS

3 HOW THE SEPARATOR AND OIL CONTENT MONITOR WORK

Check that those taking part understand the principles of how the separator and OCM work Answer any

questions they may have Points to stress are

bull Separation starts in the holding tank Because oil and water have a different specific gravity the static mixture of the two liqu ids in the tank will separate with oil rising to the top which from there can be drawn off into a waste oil tank This lowers the concentration of oil in the water towards the bottom of the tank making it easier for the separator to deal with

bull The present generation of separators contain two stages

4 OPERATION OF THE SEPARATOR

The details to cover in th is secti on w ill obvi ou sly depend on the make and mode l of the separator on your sh ip Find out wh ether the group ever experience any probLem s when running the equ ipment Ask for any suggesti ons they may have for improvements

You may wish to stress the following general points which were covered in the video

bull It is good practice to put the manufacturers operating instructions in an easily visible position near the separator Encourage those who operate the equipment to check the instructions even if they have used it before Sometimes even experienced operators can overlook something important

bull At the end of each cycle whoever is operating the separator should back-flush the equipment with clean water This cleans the filters in Stage 2 and removes any remaining oil from Stage 1 The separator should be Left full of clean water so that it is ready for the next time it is used

bull At the beginning of each separat ion cycle it is important to zero test the oeM with clean water

bull At the beginning and end of each cycle it is essential to check the ship s exact posit ion as this information must be entered in the Oil Record Book

bull On many ships [yours1 there is a float in the bilge ho lding tank wh ich will stop the separator running before the concentration of oil in the water becomes too great for it to cope with If this is not the case on your sh ip stress that the operator should estimate the amount of pumpable water in the system so that it can be shut down before the separator is flooded with concentrated oiL It is not acceptable pract ice to run the equipme nt until the alarm sounds

Explain and discuss any standing orders on your ship which are additional to the procedures called for in the statutory regulations

15

ENG INE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATO RS VIDEOTEL PRODUCTIONS

5 MAINTENANCE

Discuss the PMS for your separator with the group

bull Check that they understand the important points which it covers

bull Find out whether they have any problems maintaining the equipment or ideas for improvement

bull Explain how you verify that maintenance schedules are being followed

bull Stress the importance of keeping sufficient spares on board

Explain the key points from the fault list for your separator Stress that when faults occur

bull They must stop the separator running as soon as the fault deveLops rather than waiting until they have identified the problem There must never be any risk that water with an oil content above the 15 ppm limit could be discharged overboard

bull They must avoid any temptation to break or bend the rules If a problem arises which can onLy be solved by doing something illegal that is an issue for the shore office to sort out

6 SECURITY

The video highlighted the use of

bull White boxes These prevent anyone tampering with the OCM

bull Seals on valves and flanges in the engine room These ensure that no one can interfere with any pipe work containing oil or oily wastes Some seals are pLastic so that they can be removed quickLy in an emergency Others are chains secured by padLocks The numbers of plastic seals are recorded in the engine room Logbooks and the Chief Engineer keeps the keys to any padlocks

Discuss with the group the steps taken on your ship to protect the security of the equipment for handling oily water

16

ENGINE ROOM WASTE MANAGEMENT OILYWATER AND SEPARATORS VIDEOTEL PRODUCTIONS

7 THE NEW GENERATION OF SEPARATORS

As the student pointed out to the engineer in the video the current generation of separators have some

important disadvantages and limitations They cope badly with dirt soot emulsifiers and oil at too high a concentration Rough sea conditions lower the efficiency of separation For these reasons it is often difficult for even the most experienced engineers to make them work properly

That is why the IMO has introduced a revised set of guidelines and specifications for separators These

are set out in M EPCl 07[49]

MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committee s 107th

resolution passed at their 49th session The full title of the resolution is

Revised guidelines and specifications for pollut ion prevention equipment for machinery spaces of ships

In addition to the usual introduction explanation of the background and definitions the resolution contains

bull Techn icaL specifications

bull Specifications for type approvaL testing of poLlut ion prevention equipment

bull Installation requirements

bull Installations fitted to ships the keel of which are laid or wh ich are at a similar stage of construction on or after 1 January 2005 and

bull To new installations fitted on or after 1 January 2005 to ships the keel of wh ich were laid or wh ich were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable

The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph

It should be understood that a 15ppm Bilge Separator must be capabLe of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oiL of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emuLsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emuls ify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oiL from the emulsion to produce an effluent w ith an oil content not exceeding 15ppm

1 INTRODUCTION

Explain that

bull This short training programme is about oily water

bull It is in two parts This part is about where oily water comes from how to minimise its quantity and how to control its content so that the separator and oil content monitor are able to work properly Part 2 covers how the separator and oil content monitor work how to operate and maintain them simple security precautions and an outline of the new generation of separators

bull You will show them a video lasting about 15 minutes

bull You will then lead a discussion about the points raised in the video The main objective of this discussion is to identify and agree ways of handling oily water better on your ship Stress that you want their ideas and suggestions

Remind the group that the discharge of oily water whether through the separator or to shore based facilities is strictly controlled by internationally agreed regulations and it is inspected by port state

authorities The limit for discharge at sea is 15ppm Iparts per million] and the ship must be en route

during discharge

Ask them if they know what 15ppm means It is roughLy a coffee cup of oiL in 20m3 of water

3 POINTS FROM THE VIDEO

Ask the group what they thought were the important points from the video In summary these are

bull There are many sources of oily water - such as Leaks spills overfLows and condensation

bull Good housekeeping can reduce the quantity of oily water coming from many of these sources A leak that drips every second can put 30 or 40 litres into the bilges in a day

bull Cleaning is a particular issue

bull Controlling the content as well as the quantity of the oily water that reaches the bilges is important If it contains too much oiL t he separator may struggLe to cope with it If it contains impurities such as soot the OCM may not work properly

4 SOURCES - LEAKS ETC

bull Ask the group for suggestions about how to reduce the amount of oily water from leaks spills and overflows

bull Check that they understand and are following the procedures for handling items contaminated with oil - filters oiLy rags and so on Ask for any ideas about how to do this better

bull Stress the importance of keeping as much oil as possible out of the bilges by for example carefully emptying drip trays

bull Add any points for improvement which the group have not suggested

9

5 SOURCES - CLEANING

Discuss and identify improvements in the procedures for the following cleaning tasks

bull Keeping bilges and holding tanks as clean as possible

bull Preventing emulsifiers getting into the bilge water

bull Clean ing the air cooler in the charge air receiver

bull Disposing of gas oi l used for cleaning

bull Handling water contaminated with soot from pressure wash ing the waste heat recovery unit in the fu nnel while in port

3 HOW THE SEPARATOR AND OIL CONTENT MONITOR WORK

Check that those taking part understand the principles of how the separator and OCM work Answer any

questions they may have Points to stress are

bull Separation starts in the holding tank Because oil and water have a different specific gravity the static mixture of the two liqu ids in the tank will separate with oil rising to the top which from there can be drawn off into a waste oil tank This lowers the concentration of oil in the water towards the bottom of the tank making it easier for the separator to deal with

bull The present generation of separators contain two stages

4 OPERATION OF THE SEPARATOR

The details to cover in th is secti on w ill obvi ou sly depend on the make and mode l of the separator on your sh ip Find out wh ether the group ever experience any probLem s when running the equ ipment Ask for any suggesti ons they may have for improvements

You may wish to stress the following general points which were covered in the video

bull It is good practice to put the manufacturers operating instructions in an easily visible position near the separator Encourage those who operate the equipment to check the instructions even if they have used it before Sometimes even experienced operators can overlook something important

bull At the end of each cycle whoever is operating the separator should back-flush the equipment with clean water This cleans the filters in Stage 2 and removes any remaining oil from Stage 1 The separator should be Left full of clean water so that it is ready for the next time it is used

bull At the beginning of each separat ion cycle it is important to zero test the oeM with clean water

bull At the beginning and end of each cycle it is essential to check the ship s exact posit ion as this information must be entered in the Oil Record Book

bull On many ships [yours1 there is a float in the bilge ho lding tank wh ich will stop the separator running before the concentration of oil in the water becomes too great for it to cope with If this is not the case on your sh ip stress that the operator should estimate the amount of pumpable water in the system so that it can be shut down before the separator is flooded with concentrated oiL It is not acceptable pract ice to run the equipme nt until the alarm sounds

Explain and discuss any standing orders on your ship which are additional to the procedures called for in the statutory regulations

15

ENG INE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATO RS VIDEOTEL PRODUCTIONS

5 MAINTENANCE

Discuss the PMS for your separator with the group

bull Check that they understand the important points which it covers

bull Find out whether they have any problems maintaining the equipment or ideas for improvement

bull Explain how you verify that maintenance schedules are being followed

bull Stress the importance of keeping sufficient spares on board

Explain the key points from the fault list for your separator Stress that when faults occur

bull They must stop the separator running as soon as the fault deveLops rather than waiting until they have identified the problem There must never be any risk that water with an oil content above the 15 ppm limit could be discharged overboard

bull They must avoid any temptation to break or bend the rules If a problem arises which can onLy be solved by doing something illegal that is an issue for the shore office to sort out

6 SECURITY

The video highlighted the use of

bull White boxes These prevent anyone tampering with the OCM

bull Seals on valves and flanges in the engine room These ensure that no one can interfere with any pipe work containing oil or oily wastes Some seals are pLastic so that they can be removed quickLy in an emergency Others are chains secured by padLocks The numbers of plastic seals are recorded in the engine room Logbooks and the Chief Engineer keeps the keys to any padlocks

Discuss with the group the steps taken on your ship to protect the security of the equipment for handling oily water

ENGINE ROOM WASTE MANAGEMENT OILYWATER AND SEPARATORS VIDEOTEL PRODUCTIONS

7 THE NEW GENERATION OF SEPARATORS

As the student pointed out to the engineer in the video the current generation of separators have some

important disadvantages and limitations They cope badly with dirt soot emulsifiers and oil at too high a concentration Rough sea conditions lower the efficiency of separation For these reasons it is often difficult for even the most experienced engineers to make them work properly

That is why the IMO has introduced a revised set of guidelines and specifications for separators These

are set out in M EPCl 07[49]

MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committee s 107th

resolution passed at their 49th session The full title of the resolution is

Revised guidelines and specifications for pollut ion prevention equipment for machinery spaces of ships

In addition to the usual introduction explanation of the background and definitions the resolution contains

bull Techn icaL specifications

bull Specifications for type approvaL testing of poLlut ion prevention equipment

bull Installation requirements

17

ENGINE ROOM WASTE MANAGEMENT OI LY WATER AND SEPARATORS VIDEOTEL PRODUCTI ONS

These new requirements apply to

bull Installations fitted to ships the keel of which are laid or wh ich are at a similar stage of construction on or after 1 January 2005 and

bull To new installations fitted on or after 1 January 2005 to ships the keel of wh ich were laid or wh ich were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable

The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph

It should be understood that a 15ppm Bilge Separator must be capabLe of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oiL of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emuLsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emuls ify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oiL from the emulsion to produce an effluent w ith an oil content not exceeding 15ppm

Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based

These new requirements apply to

bull Installations fitted to ships the keel of which are laid or wh ich are at a similar stage of construction on or after 1 January 2005 and

bull To new installations fitted on or after 1 January 2005 to ships the keel of wh ich were laid or wh ich were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable

The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph

It should be understood that a 15ppm Bilge Separator must be capabLe of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oiL of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emuLsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emuls ify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oiL from the emulsion to produce an effluent w ith an oil content not exceeding 15ppm

Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based

1 INTRODUCTION

Explain that

bull This short training programme is about oily water

bull It is in two parts This part is about where oily water comes from how to minimise its quantity and how to control its content so that the separator and oil content monitor are able to work properly Part 2 covers how the separator and oil content monitor work how to operate and maintain them simple security precautions and an outline of the new generation of separators

bull You will show them a video lasting about 15 minutes

bull You will then lead a discussion about the points raised in the video The main objective of this discussion is to identify and agree ways of handling oily water better on your ship Stress that you want their ideas and suggestions

Remind the group that the discharge of oily water whether through the separator or to shore based facilities is strictly controlled by internationally agreed regulations and it is inspected by port state

authorities The limit for discharge at sea is 15ppm Iparts per million] and the ship must be en route

during discharge

Ask them if they know what 15ppm means It is roughLy a coffee cup of oiL in 20m3 of water

ENGINE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATORS VIDEOTEL PRODUCTIONS

3 POINTS FROM THE VIDEO

Ask the group what they thought were the important points from the video In summary these are

bull There are many sources of oily water - such as Leaks spills overfLows and condensation

bull Good housekeeping can reduce the quantity of oily water coming from many of these sources A leak that drips every second can put 30 or 40 litres into the bilges in a day

bull Cleaning is a particular issue

bull Controlling the content as well as the quantity of the oily water that reaches the bilges is important If it contains too much oiL t he separator may struggLe to cope with it If it contains impurities such as soot the OCM may not work properly

4 SOURCES - LEAKS ETC

bull Ask the group for suggestions about how to reduce the amount of oily water from leaks spills and overflows

bull Check that they understand and are following the procedures for handling items contaminated with oil - filters oiLy rags and so on Ask for any ideas about how to do this better

bull Stress the importance of keeping as much oil as possible out of the bilges by for example carefully emptying drip trays

bull Add any points for improvement which the group have not suggested

9

ENGINE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATORS VIDEOTEL PRODUCTIONS

5 SOURCES - CLEANING

Discuss and identify improvements in the procedures for the following cleaning tasks

bull Keeping bilges and holding tanks as clean as possible

bull Preventing emulsifiers getting into the bilge water

bull Clean ing the air cooler in the charge air receiver

bull Disposing of gas oi l used for cleaning

bull Handling water contaminated with soot from pressure wash ing the waste heat recovery unit in the fu nnel while in port

ENGINE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATORS VIDEOTEL PRODUCTIONS

3 HOW THE SEPARATOR AND OIL CONTENT MONITOR WORK

Check that those taking part understand the principles of how the separator and OCM work Answer any

questions they may have Points to stress are

bull Separation starts in the holding tank Because oil and water have a different specific gravity the static mixture of the two liqu ids in the tank will separate with oil rising to the top which from there can be drawn off into a waste oil tank This lowers the concentration of oil in the water towards the bottom of the tank making it easier for the separator to deal with

bull The present generation of separators contain two stages

4 OPERATION OF THE SEPARATOR

The details to cover in th is secti on w ill obvi ou sly depend on the make and mode l of the separator on your sh ip Find out wh ether the group ever experience any probLem s when running the equ ipment Ask for any suggesti ons they may have for improvements

You may wish to stress the following general points which were covered in the video

bull It is good practice to put the manufacturers operating instructions in an easily visible position near the separator Encourage those who operate the equipment to check the instructions even if they have used it before Sometimes even experienced operators can overlook something important

bull At the end of each cycle whoever is operating the separator should back-flush the equipment with clean water This cleans the filters in Stage 2 and removes any remaining oil from Stage 1 The separator should be Left full of clean water so that it is ready for the next time it is used

bull At the beginning of each separat ion cycle it is important to zero test the oeM with clean water

bull At the beginning and end of each cycle it is essential to check the ship s exact posit ion as this information must be entered in the Oil Record Book

bull On many ships [yours1 there is a float in the bilge ho lding tank wh ich will stop the separator running before the concentration of oil in the water becomes too great for it to cope with If this is not the case on your sh ip stress that the operator should estimate the amount of pumpable water in the system so that it can be shut down before the separator is flooded with concentrated oiL It is not acceptable pract ice to run the equipme nt until the alarm sounds

Explain and discuss any standing orders on your ship which are additional to the procedures called for in the statutory regulations

15

ENG INE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATO RS VIDEOTEL PRODUCTIONS

5 MAINTENANCE

Discuss the PMS for your separator with the group

bull Check that they understand the important points which it covers

bull Find out whether they have any problems maintaining the equipment or ideas for improvement

bull Explain how you verify that maintenance schedules are being followed

bull Stress the importance of keeping sufficient spares on board

Explain the key points from the fault list for your separator Stress that when faults occur

bull They must stop the separator running as soon as the fault deveLops rather than waiting until they have identified the problem There must never be any risk that water with an oil content above the 15 ppm limit could be discharged overboard

bull They must avoid any temptation to break or bend the rules If a problem arises which can onLy be solved by doing something illegal that is an issue for the shore office to sort out

6 SECURITY

The video highlighted the use of

bull White boxes These prevent anyone tampering with the OCM

bull Seals on valves and flanges in the engine room These ensure that no one can interfere with any pipe work containing oil or oily wastes Some seals are pLastic so that they can be removed quickLy in an emergency Others are chains secured by padLocks The numbers of plastic seals are recorded in the engine room Logbooks and the Chief Engineer keeps the keys to any padlocks

Discuss with the group the steps taken on your ship to protect the security of the equipment for handling oily water

16

ENGINE ROOM WASTE MANAGEMENT OILYWATER AND SEPARATORS VIDEOTEL PRODUCTIONS

7 THE NEW GENERATION OF SEPARATORS

As the student pointed out to the engineer in the video the current generation of separators have some

important disadvantages and limitations They cope badly with dirt soot emulsifiers and oil at too high a concentration Rough sea conditions lower the efficiency of separation For these reasons it is often difficult for even the most experienced engineers to make them work properly

That is why the IMO has introduced a revised set of guidelines and specifications for separators These

are set out in M EPCl 07[49]

MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committee s 107th

bull To new installations fitted on or after 1 January 2005 to ships the keel of wh ich were laid or wh ich were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable

The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph

Remind the group that the video shows a conversation between an eng ineer officer and a student who is nearing the end of her universi ty degree course in mechanical engineering and is cons idering a career at sea In PART 1 they discussed the sources of oily water In th is part they talk about how oiLy water is dealt with

3 HOW THE SEPARATOR AND OIL CONTENT MONITOR WORK

Check that those taking part understand the principles of how the separator and OCM work Answer any

questions they may have Points to stress are

bull Separation starts in the holding tank Because oil and water have a different specific gravity the static mixture of the two liqu ids in the tank will separate with oil rising to the top which from there can be drawn off into a waste oil tank This lowers the concentration of oil in the water towards the bottom of the tank making it easier for the separator to deal with

bull The present generation of separators contain two stages

4 OPERATION OF THE SEPARATOR

The details to cover in th is secti on w ill obvi ou sly depend on the make and mode l of the separator on your sh ip Find out wh ether the group ever experience any probLem s when running the equ ipment Ask for any suggesti ons they may have for improvements

You may wish to stress the following general points which were covered in the video

bull It is good practice to put the manufacturers operating instructions in an easily visible position near the separator Encourage those who operate the equipment to check the instructions even if they have used it before Sometimes even experienced operators can overlook something important

bull At the end of each cycle whoever is operating the separator should back-flush the equipment with clean water This cleans the filters in Stage 2 and removes any remaining oil from Stage 1 The separator should be Left full of clean water so that it is ready for the next time it is used

bull At the beginning of each separat ion cycle it is important to zero test the oeM with clean water

bull At the beginning and end of each cycle it is essential to check the ship s exact posit ion as this information must be entered in the Oil Record Book

bull On many ships [yours1 there is a float in the bilge ho lding tank wh ich will stop the separator running before the concentration of oil in the water becomes too great for it to cope with If this is not the case on your sh ip stress that the operator should estimate the amount of pumpable water in the system so that it can be shut down before the separator is flooded with concentrated oiL It is not acceptable pract ice to run the equipme nt until the alarm sounds

Explain and discuss any standing orders on your ship which are additional to the procedures called for in the statutory regulations

5 MAINTENANCE

Discuss the PMS for your separator with the group

bull Check that they understand the important points which it covers

bull Find out whether they have any problems maintaining the equipment or ideas for improvement

bull Explain how you verify that maintenance schedules are being followed

bull Stress the importance of keeping sufficient spares on board

Explain the key points from the fault list for your separator Stress that when faults occur

bull They must stop the separator running as soon as the fault deveLops rather than waiting until they have identified the problem There must never be any risk that water with an oil content above the 15 ppm limit could be discharged overboard

bull They must avoid any temptation to break or bend the rules If a problem arises which can onLy be solved by doing something illegal that is an issue for the shore office to sort out

6 SECURITY

The video highlighted the use of

bull White boxes These prevent anyone tampering with the OCM

bull Seals on valves and flanges in the engine room These ensure that no one can interfere with any pipe work containing oil or oily wastes Some seals are pLastic so that they can be removed quickLy in an emergency Others are chains secured by padLocks The numbers of plastic seals are recorded in the engine room Logbooks and the Chief Engineer keeps the keys to any padlocks

Discuss with the group the steps taken on your ship to protect the security of the equipment for handling oily water

7 THE NEW GENERATION OF SEPARATORS

As the student pointed out to the engineer in the video the current generation of separators have some

important disadvantages and limitations They cope badly with dirt soot emulsifiers and oil at too high a concentration Rough sea conditions lower the efficiency of separation For these reasons it is often difficult for even the most experienced engineers to make them work properly

That is why the IMO has introduced a revised set of guidelines and specifications for separators These

are set out in M EPCl 07[49]

MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committee s 107th

resolution passed at their 49th session The full title of the resolution is

Revised guidelines and specifications for pollut ion prevention equipment for machinery spaces of ships

In addition to the usual introduction explanation of the background and definitions the resolution contains

bull Techn icaL specifications

bull Specifications for type approvaL testing of poLlut ion prevention equipment

bull Installation requirements

17

ENGINE ROOM WASTE MANAGEMENT OI LY WATER AND SEPARATORS VIDEOTEL PRODUCTI ONS

These new requirements apply to

bull Installations fitted to ships the keel of which are laid or wh ich are at a similar stage of construction on or after 1 January 2005 and

bull To new installations fitted on or after 1 January 2005 to ships the keel of wh ich were laid or wh ich were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable

The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph

It should be understood that a 15ppm Bilge Separator must be capabLe of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oiL of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emuLsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emuls ify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oiL from the emulsion to produce an effluent w ith an oil content not exceeding 15ppm

Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based

1 INTRODUCTION

Explain that

bull PART 2 of this short training programme covers how t he separator and OeM work how to operate and ma inta in them including tackling faults simple security precautions and an outline of the new generation of separators

bull As in PART 1 you will show them a video lasting about 15 minutes followed by a discussion about the points raised in the video The main objective of this discussion is to identify and agree ways of handling oily water better on your ship Stress that you want their ideas and suggestions

2 THE VIDEO

Remind the group that the video shows a conversation between an eng ineer officer and a student who is nearing the end of her universi ty degree course in mechanical engineering and is cons idering a career at sea In PART 1 they discussed the sources of oily water In th is part they talk about how oiLy water is dealt with

3 HOW THE SEPARATOR AND OIL CONTENT MONITOR WORK

Check that those taking part understand the principles of how the separator and OCM work Answer any

questions they may have Points to stress are

bull Separation starts in the holding tank Because oil and water have a different specific gravity the static mixture of the two liqu ids in the tank will separate with oil rising to the top which from there can be drawn off into a waste oil tank This lowers the concentration of oil in the water towards the bottom of the tank making it easier for the separator to deal with

bull The present generation of separators contain two stages

4 OPERATION OF THE SEPARATOR

The details to cover in th is secti on w ill obvi ou sly depend on the make and mode l of the separator on your sh ip Find out wh ether the group ever experience any probLem s when running the equ ipment Ask for any suggesti ons they may have for improvements

You may wish to stress the following general points which were covered in the video

bull It is good practice to put the manufacturers operating instructions in an easily visible position near the separator Encourage those who operate the equipment to check the instructions even if they have used it before Sometimes even experienced operators can overlook something important

bull At the end of each cycle whoever is operating the separator should back-flush the equipment with clean water This cleans the filters in Stage 2 and removes any remaining oil from Stage 1 The separator should be Left full of clean water so that it is ready for the next time it is used

bull At the beginning of each separat ion cycle it is important to zero test the oeM with clean water

bull At the beginning and end of each cycle it is essential to check the ship s exact posit ion as this information must be entered in the Oil Record Book

bull On many ships [yours1 there is a float in the bilge ho lding tank wh ich will stop the separator running before the concentration of oil in the water becomes too great for it to cope with If this is not the case on your sh ip stress that the operator should estimate the amount of pumpable water in the system so that it can be shut down before the separator is flooded with concentrated oiL It is not acceptable pract ice to run the equipme nt until the alarm sounds

Explain and discuss any standing orders on your ship which are additional to the procedures called for in the statutory regulations

15

ENG INE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATO RS VIDEOTEL PRODUCTIONS

5 MAINTENANCE

Discuss the PMS for your separator with the group

bull Check that they understand the important points which it covers

bull Find out whether they have any problems maintaining the equipment or ideas for improvement

bull Explain how you verify that maintenance schedules are being followed

bull Stress the importance of keeping sufficient spares on board

Explain the key points from the fault list for your separator Stress that when faults occur

bull They must stop the separator running as soon as the fault deveLops rather than waiting until they have identified the problem There must never be any risk that water with an oil content above the 15 ppm limit could be discharged overboard

bull They must avoid any temptation to break or bend the rules If a problem arises which can onLy be solved by doing something illegal that is an issue for the shore office to sort out

6 SECURITY

The video highlighted the use of

bull White boxes These prevent anyone tampering with the OCM

bull Seals on valves and flanges in the engine room These ensure that no one can interfere with any pipe work containing oil or oily wastes Some seals are pLastic so that they can be removed quickLy in an emergency Others are chains secured by padLocks The numbers of plastic seals are recorded in the engine room Logbooks and the Chief Engineer keeps the keys to any padlocks

Discuss with the group the steps taken on your ship to protect the security of the equipment for handling oily water

7 THE NEW GENERATION OF SEPARATORS

As the student pointed out to the engineer in the video the current generation of separators have some

important disadvantages and limitations They cope badly with dirt soot emulsifiers and oil at too high a concentration Rough sea conditions lower the efficiency of separation For these reasons it is often difficult for even the most experienced engineers to make them work properly

That is why the IMO has introduced a revised set of guidelines and specifications for separators These

are set out in M EPCl 07[49]

MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committee s 107th

resolution passed at their 49th session The full title of the resolution is

Revised guidelines and specifications for pollut ion prevention equipment for machinery spaces of ships

In addition to the usual introduction explanation of the background and definitions the resolution contains

bull Techn icaL specifications

bull Specifications for type approvaL testing of poLlut ion prevention equipment

bull Installation requirements

17

ENGINE ROOM WASTE MANAGEMENT OI LY WATER AND SEPARATORS VIDEOTEL PRODUCTI ONS

These new requirements apply to

bull Installations fitted to ships the keel of which are laid or wh ich are at a similar stage of construction on or after 1 January 2005 and

bull To new installations fitted on or after 1 January 2005 to ships the keel of wh ich were laid or wh ich were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable

The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph

It should be understood that a 15ppm Bilge Separator must be capabLe of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oiL of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emuLsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emuls ify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oiL from the emulsion to produce an effluent w ith an oil content not exceeding 15ppm

Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based

The details to cover in th is secti on w ill obvi ou sly depend on the make and mode l of the separator on your sh ip Find out wh ether the group ever experience any probLem s when running the equ ipment Ask for any suggesti ons they may have for improvements

You may wish to stress the following general points which were covered in the video

bull It is good practice to put the manufacturers operating instructions in an easily visible position near the separator Encourage those who operate the equipment to check the instructions even if they have used it before Sometimes even experienced operators can overlook something important

bull At the end of each cycle whoever is operating the separator should back-flush the equipment with clean water This cleans the filters in Stage 2 and removes any remaining oil from Stage 1 The separator should be Left full of clean water so that it is ready for the next time it is used

bull At the beginning of each separat ion cycle it is important to zero test the oeM with clean water

bull At the beginning and end of each cycle it is essential to check the ship s exact posit ion as this information must be entered in the Oil Record Book

bull On many ships [yours1 there is a float in the bilge ho lding tank wh ich will stop the separator running before the concentration of oil in the water becomes too great for it to cope with If this is not the case on your sh ip stress that the operator should estimate the amount of pumpable water in the system so that it can be shut down before the separator is flooded with concentrated oiL It is not acceptable pract ice to run the equipme nt until the alarm sounds

Explain and discuss any standing orders on your ship which are additional to the procedures called for in the statutory regulations

Discuss the PMS for your separator with the group

bull Check that they understand the important points which it covers

bull Find out whether they have any problems maintaining the equipment or ideas for improvement

bull Explain how you verify that maintenance schedules are being followed

bull Stress the importance of keeping sufficient spares on board

Explain the key points from the fault list for your separator Stress that when faults occur

bull They must stop the separator running as soon as the fault deveLops rather than waiting until they have identified the problem There must never be any risk that water with an oil content above the 15 ppm limit could be discharged overboard

bull They must avoid any temptation to break or bend the rules If a problem arises which can onLy be solved by doing something illegal that is an issue for the shore office to sort out

6 SECURITY

The video highlighted the use of

bull White boxes These prevent anyone tampering with the OCM

bull Seals on valves and flanges in the engine room These ensure that no one can interfere with any pipe work containing oil or oily wastes Some seals are pLastic so that they can be removed quickLy in an emergency Others are chains secured by padLocks The numbers of plastic seals are recorded in the engine room Logbooks and the Chief Engineer keeps the keys to any padlocks

Discuss with the group the steps taken on your ship to protect the security of the equipment for handling oily water

7 THE NEW GENERATION OF SEPARATORS

As the student pointed out to the engineer in the video the current generation of separators have some

important disadvantages and limitations They cope badly with dirt soot emulsifiers and oil at too high a concentration Rough sea conditions lower the efficiency of separation For these reasons it is often difficult for even the most experienced engineers to make them work properly

That is why the IMO has introduced a revised set of guidelines and specifications for separators These

are set out in M EPCl 07[49]

MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committee s 107th

resolution passed at their 49th session The full title of the resolution is

Revised guidelines and specifications for pollut ion prevention equipment for machinery spaces of ships

In addition to the usual introduction explanation of the background and definitions the resolution contains

bull Techn icaL specifications

bull Specifications for type approvaL testing of poLlut ion prevention equipment

bull Installation requirements

ENGINE ROOM WASTE MANAGEMENT OI LY WATER AND SEPARATORS VIDEOTEL PRODUCTI ONS

bull Installations fitted to ships the keel of which are laid or wh ich are at a similar stage of construction on or after 1 January 2005 and

bull To new installations fitted on or after 1 January 2005 to ships the keel of wh ich were laid or wh ich were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable

The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph

It should be understood that a 15ppm Bilge Separator must be capabLe of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oiL of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emuLsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emuls ify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oiL from the emulsion to produce an effluent w ith an oil content not exceeding 15ppm

Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based

important disadvantages and limitations They cope badly with dirt soot emulsifiers and oil at too high a concentration Rough sea conditions lower the efficiency of separation For these reasons it is often difficult for even the most experienced engineers to make them work properly

That is why the IMO has introduced a revised set of guidelines and specifications for separators These

are set out in M EPCl 07[49]

MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committee s 107th

resolution passed at their 49th session The full title of the resolution is

Revised guidelines and specifications for pollut ion prevention equipment for machinery spaces of ships

In addition to the usual introduction explanation of the background and definitions the resolution contains

bull Techn icaL specifications

bull Specifications for type approvaL testing of poLlut ion prevention equipment

bull Installation requirements

These new requirements apply to

bull Installations fitted to ships the keel of which are laid or wh ich are at a similar stage of construction on or after 1 January 2005 and

bull To new installations fitted on or after 1 January 2005 to ships the keel of wh ich were laid or wh ich were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable

The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph

It should be understood that a 15ppm Bilge Separator must be capabLe of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oiL of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emuLsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emuls ify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oiL from the emulsion to produce an effluent w ith an oil content not exceeding 15ppm

Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based

5 MAINTENANCE

Discuss the PMS for your separator with the group

bull Check that they understand the important points which it covers

bull Find out whether they have any problems maintaining the equipment or ideas for improvement

bull Explain how you verify that maintenance schedules are being followed

bull Stress the importance of keeping sufficient spares on board

Explain the key points from the fault list for your separator Stress that when faults occur

bull They must stop the separator running as soon as the fault deveLops rather than waiting until they have identified the problem There must never be any risk that water with an oil content above the 15 ppm limit could be discharged overboard

bull They must avoid any temptation to break or bend the rules If a problem arises which can onLy be solved by doing something illegal that is an issue for the shore office to sort out

6 SECURITY

The video highlighted the use of

bull White boxes These prevent anyone tampering with the OCM

bull Seals on valves and flanges in the engine room These ensure that no one can interfere with any pipe work containing oil or oily wastes Some seals are pLastic so that they can be removed quickLy in an emergency Others are chains secured by padLocks The numbers of plastic seals are recorded in the engine room Logbooks and the Chief Engineer keeps the keys to any padlocks

Discuss with the group the steps taken on your ship to protect the security of the equipment for handling oily water

The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph

It should be understood that a 15ppm Bilge Separator must be capabLe of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oiL of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emuLsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emuls ify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oiL from the emulsion to produce an effluent w ith an oil content not exceeding 15ppm

Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based
