BULK PROTECTOR Cargo Holds Water Ingress Monitoring & Alarm Detection System

BULK PROTECTOR Cargo Holds Water Ingress Monitoring & Alarm

Detection System Introduction SELMA Cargo Holds Water Ingress Detection System “BULK PROTECTOR” supervises

and detects Water presence in Cargo Holds Area, any Ballast Tank and any Dry/Void

Space any part of which extends forward of Foremost Cargo Hold (other than chain

locker).

The main aim of the System is to perform Detection by generating Audible & Visual

Alarm Signal by indicating the Point where the Water was detected.

In particular according to IMO Resolution MSC.145 (77) “Performance Standards for

Water Level Detectors on Bulk Carriers” and IACS Unified Interpretation (UI) SC180 the

supervision should be implemented on the following points :

Specifically in Cargo Holds Area the Alarm is performed when Water Level reaches

0.5m & 2.0m Height from inner Bottom. In Fore Peak Tank or Ballast Tank Area forward

of Collision Bulkhead, the Alarm is performed when Water Level reaches 10% of Tank

Level Capacity. In any Dry or Void Space Forward of foremost cargo hold the Alarm

Signal is performed when Water Level reaches 0.1m above Deck.

Furthermore Override Buttons are comprised in order to disable Alarm on Fore Peak

Tank, Ballast Tank forward of Collision Bulkhead and in Holds that are used as Ballast.

When the Water Level is below Alarm Set Points then automatically the Fore Peak Tank,

Ballast Tank & Ballast Hold Override function change over into Alarm Normal Operation

according to MSC.145 (77).

Finally all Alarms are performed according to IMO “ Code on Alarms and Indications

1995” refer to 3.3.2 of IMO Resolution MSC.145 (77).

Philosophy of BULK PROTECTOR The Philosophy of BULK PROTECTOR is the following :

Sensor Operation (Cargo Holds & Ballast Tanks forward of Collision Bulkhead) :

In particular when in one of the supervised Areas in Bulk Carriers is inserted Water, then

the Water implements hydrostatic Pressure related to its Level. The Sensors that are

installed in Bottom of the Cargo Holds & Ballast Tank are Submersible Electronic Level

Transmitters and provide Continuous Water Level Monitoring by transmitting Signal 4-

20mA. The Submersible Level Pressure Transmitters perform Water Level

measurement with the hydrostatic pressure that is applied on the Transmitter. The direct

conversion of the pressure into an electrical signal is achieved by a minute deflection of

sensor which changes the resistance of the bridge with the applied stress. Changes in

pressure cause a corresponding change in the transmitter output in proportion to the

bridge unbalance. A single electronic circuit supplies power to sensor receives its signal

providing conversion into 4-20mA. The Submersible Electronic Transmitters are

Stainless Steel, Ex & Marine Approved with IP68 Circuit Enclosures.

Sensor Operation (Dry/Void Space fwd of foremost Cargo Hold if existed in Vessel) :

If vessel comprises Dry/Void Space forward of Foremost Cargo Hold is installed

Ultrasonic Level Sensor on height 0.1m above Deck (Refer to Sensor Installation

Diagram). It is worthy to be noted that Ultrasonic Level Sensor is designed for Marine

Applications for liquid detection and operate on the principle of distributed acoustic

waves in a metal rod. If the rod is not covered by the liquid the sound waves are

dispersed freely without any interference. If liquid covers the rod the emission of sound

waves is muffled and this interference is picked up by the piezoelectric sensor and

transmitted by a Signal to the Current Loop (On-Off). The Ultrasonic Level Sensor is

Stainless Steel, Ex, Marine Approved with IP68 Circuit Enclosure.

The installation of Sensors is illustrated on attached Diagrams according to Vessel

particular Specifications. Protection procedure of Sensors is predicted [Refer to Sensor

Installation Diagrams] in order to avoid contact of Sensors with Cargo and implement

protection from Unloading Machineries.



The Installation inside Cargo Holds is intrinsically safe according to IMO Resolution

MSC145(77)”Performance Standards for Water Level Detectors on Bulk Carriers” and

IACS (UI) SC180. The Sensors in Cargo Holds are Intrinsically Safe and Zenner Barriers

are comprised in Local Junction Boxes in order to perform Ex Installation.

Cargo Holds Sensors are tested according to IACS SC180 with Sand, Coal, Iron, Grain

Local Junction Boxes of BULK PROTECTOR: The Transmitted Signal is 4 – 20mA and the Transmission is implemented through

Special Submersible Cable that is fixed with Sensor. (Sea Water Resistant & High Temp

Resistant up to 120oC) which is connected on Deck Corresponding Local Junction Box

of specific Hold or Fore Peak Tank [Local J. Box]. All Signals from Local junction

Boxes are concentrated on Final Main Junction Box.

The Cargo Holds Sensors Signals are passed through Zenner Barriers (Local Junction

Boxes). The Signals of Fore Peak Tank and Dry/Void Space (If existed) do not require

Zenner Barrier Presence according to IMO Resolution MSC.145(77).

It is important to be noted that the Local Junction Boxes are installed on Deck of

Corresponding Hold or Fore Peak Tank and the Main Junction Box Terminal should be

installed on Upper Deck in the place where the Main Cable Line on Deck is ended.

Pipes Installation (Hold) : 1” or 1 ½ ” Pipe is installed in each Cargo Hold in mid aft part (Refer to Pipe Diagrams)

for Cable Protection. On Deck is not necessary the installation of Pipe because the Main

Existing Cable Tube is used. It is important to be mentioned that the Intrinsically Safe

Circuit Cables are considered from Local Junction Boxes (Zenner Barriers inside) until

Sensors in Cargo Hold Area. Consequently the Cables from Local Junction Boxes until

Main Junction Box Terminal and finally to Bridge Alarm System are considered as Safe

Cables and must be Armored and Marine Type.

In case that the Bulk Carrier comprises Tunnel the Cables can pass through Tunnel and

the Pipe can be avoided.


Finally if the Vessel Comprises Tunnel then Deck Installation of J.Boxes is avoided.

Refer to Sensor operation inside Cargo Holds & Fore Peak Tank it should be noted that

the measuring Range is from Inner Bottom until to Deck Top.

particles and sea water as representative of the range of cargos. [IACS 180 - 5].


Cabling Procedure : The cables that are installed from Local Junction Boxes to Main junction Box is

recommended to be 2x1mm2 or 2x1.5mm2 Armored and Marine Type. From Main

Junction Box Terminal until the Monitoring & Alarm PLC System the cable that is used

is 12x1mm2 or 12x1.5mm2. If the Bulk Carrier is until 4 Holds then 1 cable 12x1mm2 or

12x1.5mm2 is used. If the Bulk Carrier is from 5 – 9 Holds then 2 Cables 12x1mm2 are

used. In all cases it is recommended to refer on Attached General Arrangement

Installation Diagram Sheet 3.

Monitoring & Alarm PLC System :

The Monitoring & Alarm PLC System is supplied with Normal Supply 100-240V AC and

Emergency Supply 24V DC. In particular Power Supply Module(10A) is comprised with

input 100-240V AC and generates 24V DC (Stabilized). It is worthy to be noted that when

the Normal supply 100-240V AC is cut off then automatically the power supply of the

System changes from Normal into Emergency 24V DC. Furthermore Electric Fuses are

included in order to implement circuit protection and Aux. Relays for automatic power

supply change over procedure and furthermore in order to perform common alarm

functions. The Main PLC System is able to perform Discrete & Analog I/O. The Display

Bar Graph that is placed in Front is performing Monitoring, Alarm & Integrated

Supervision of System.

MAINTENANCE PROCEDURE It is important to be mentioned that the Maintenance Procedure of Cargo Holds Water

Ingress Detection System is focused on Sensor.

In particular the Sensor Cover should be cleaned each time the Crew is cleaning the

Hold Area.

The Sensors that are supplied to the Bulk Carrier are Calibrated according to Vessel’s

Technical Specification.

It is recommended to perform Recalibration of Sensors every 4 Years.

TEST PROCEDURE : It should be fitted the Adaptor that is supplied with the System on the front side of Sensor. The

adaptor is tighten with “Allen” Screws that are placed on it.

Option No1 : [Refer to Sheet 1.2]

1) On the thread that is presented on the front side with “Rakor”, it should be placed a Hand

Held Pump with Gauge Instrument (-1.0) – 0 – (+1.5) bar. By adjusting the Pressure on

50mbar it is energized the Alarm of 0.5m after time delay 25 sec. By increasing the

pressure on 200mbar (0.2 bar) it is energized the Alarm of 2.0m after time delay 25 sec.

Option No2 : [Refer to Sheet 1.3]

2) On the “Rakor” that is presented on the front side of Adaptor, it should be placed a Tube

Φ12 min with Length around 2.5m and it should be feeded with Water with Relative

Quantity with Level that the Alarm should be energized (0.5m or 2.0m).

Note : When the Adaptor is fitted on Sensor, it should be opened from the side of “Rakor” and

then place the Test Equipment of Options 1) or 2).

The Conversion Table is illustrated on Sheet 1.5.


REMARK : In all Cases before implementing the TEST

PROCEDURES remove the Protective Cup of Sensor.

(Refer to Picture 2.1) Picture 2.1


BULK PROTECTOR


REMOTE TEST PROCEDURE The Test of Sensors can be implemented also by following Remote Test Procedure. The Special

PUR Seawater Resistant Cable 25m which is fixed with Sensor, comprises internally a plastic

Tube 25m attached with the 25m cable. The Plastic Tube communicates with Flash Diaphragm of

Sensor.

- The Plastic Tube and 2 Wires are ended on Local Junction Boxes.

- Consequently the Operator can implement Remote Test by Connecting a Hand Held

Vacuum Pump on Plastic Tube, and Subtract Air from Plastic Tube.

- This is the same procedure like applying pressure on Flash Diaphragm of Sensor but

without someone entry Cargo Hold Area.

GENERAL NOTES If in the Alarm System it is presented any Measuring Level Value on a specific Hold, and

the reason might be that the specific Hold Sensor is applied with pressure by Cargo or

the specific Hold might comprises small Quantity of Water (i.e. after Cargo Cleaning), it

is recommended in this case to Set this presented value as ZERO adjust on Alarm

System and only for the Time Period of the Specific Cargo Condition.

NOTE : This parameter ZERO Adjust should be rechanged to initial value when the

specific Cargo is Unloaded.

DEFAULT BUTTON – MANUFACTURER’S SETTING

All Alarms Time Delay are Set up with 30 sec. Consequently Every Alarm is performed

after 30 sec.

In case that in several periods the Set Points parameters are changed from Operator or

are changed by mistake, then inside Alarm Panel and beside PLC it is placed a Button

with Label “Manufacturer Initial Settings”. Consequently by Pressing this Button all

Parameters will be Returned to Initial Values.

Furthermore, inside Alarm Panel it is placed 4 Pages with SELMA Default Parameters

Settings according to Vessel Specifications. Moreover it is placed 1 Page illustrating the

Nameplates of Sensors. Finally, it should be noted that each Level Transmitter Sensor

comprises at the end of PUR Cable a Mark Label indicating the recommended connection

of Sensor Channel (i.e C.H.4).
