1.1 The Team

G6 Tidal Solutions is made up of 6 team members. A tool that is now popular in team role selection

was used to determine the roles played by each team member. This tool is known as the Belbin

Team Roles Theory. It identifies the typical roles that can be characteristic to varying extents in

individuals working in a group dynamic. A Team Role came to be defined as “A tendency to behave,

contribute and interrelate with others in a particular way.” (Associates, 2007)

The members of the team are each dedicated individuals in pursuit of excellence. Each member

plays a role that is vital in order for the team to succeed as a united entity. There is also a degree of

flexibility with each role to allow for accountability and responsibility of the entire organization.

1.1.2 Company Organisational Structure

Figure 3: G6 Tidal Solutions Organisational Structure

One of the factors that affect the success of an organisation is the organisational structure.

It is of grave importance to have a clear organisational structure in order to ensure that the

right decisions are made in the company by the correct people. It also provides a clear view

of the different functional departments of an organisation. It also provides a hierarchy that

indicates a chain of command that is simple for all to understand.

1.2

The Business Plan

In order for any company to break into a market it needs to have a solid business plan. G6

Tidal Solutions has the following business plan which will aid in the journey towards a bigger

market share.

1.2.1 Mission

The mission of the company is to become a leader in Engineering and Management

consulting by providing clients with best possible solutions and business services which can

fully satisfy their requirements.

1.2.2 Aims and Objectives

Aims: G6 Tidal Solutions aim to provide high quality goods and services to its clients

through intense customer involvement in the design of products.

Objectives:

To be selected from the client, University of Greenwich, as the leading consultingbusiness for the “Tidal-Test-Tank” project

Create and maintain strong client relationships

Become an established consultancy company in the region within the period of 3 to

5 years

To become a international organization after the first 5 years of operation

1.2.3 Marketing and Promotion Strategy

G6 will be employing various media in order to create an awareness of the services it

provides. Seeing as it is a new company, it is important to gain recognition in local areas and

in the rest of the UK as soon as possible. The first step towards becoming known is to list the

company in the Yellow Pages. The next step is to create a company brochure which will be

distributed to education institutions, professional institutions, as well as relevant exhibition

events that are to be attended by the organization. The brochure will be aimed at informing

potential clients of the organisation’s range of products and services. Furthermore the




leaflet will highlight G6 Tidal Solution Limited past experience, career highlights as well as

the expertise employed.

Digital advertising marketing will help the company to create awareness outside Greater

London area and outside the English border. The internet is able to give instant exposure to

a vast potential of clients nationally and internationally by combining interactivity,

transaction, and communication. This would allow for lead times to be reduced drastically.

Its usage will boost the business by drawing customers from all over the world. The

company’s website is thus included in any printed literature that the company G6 Tidal

Solutions distributes.

1.2.4 Competitive Advantage

The key advantages of the business are:

The firm is able to provide to customers robust products

Intense quality control and thus providing quality assurance to the client

Competitive prices

Provide optional service of commissioning and installations

Capacity to innovate and modify solutions in short lead times

Ability to work using best practice operations

Create and maintaining a great level of customer satisfaction by involving the

customer in the design of their required product

Strong initial advertising/marketing

Intense customer involvement in design to ensure customer requirements are best

met

1.2.5 Future Products and Services

The company’s focus will be on expanding and upgrading its services according to customer

needs and changes in the market in order to maintain client loyalty as well as the company’s

market share.




1.3

Issues and Constraints

The main issues and constraints faced by a company that is emerging into the business

world are that the organization is at a stage where its members are still building relations

with each other in order to have a truly functioning business. This means that although

individually experienced in respective fields, the members are still learning to work as

united entity whilst trying to build customer relations at the same time. Also, being a new

company, finances are relatively limited and this may make the organisation vulnerable to

losing clients to companies that have more money to spend on projects that are similar to

those pursues by G6 Tidal Solutions Limited.

G6 Tidal Solutions is an infant company that is not yet known by the targeted market. The

main hurdle at hand is to gain the contract with the University of Greenwich in order to

prove experience in the chosen business sector.




2 Project Description

The University of Greenwich’s School of Engineering is in need of a new Tidal -Test- Tank to

be one of the testing facilities in the Hydraulics laboratory. The aim of the group design

project is for groups to propose and tender an all encompassing design to the client, The

University of Greenwich. The School of Engineering is the main vendor and will therefore

select the most suitable design for use out of the 16 competing groups of final year

students.

2.1

Problem Analysis

G6 Tidal Solution was created so that it would be able to propose a design to the client. The

first part of the project is to be able to create a team that works and shows an

understanding of how professional engineering consultants work. That is to create an

identity and set up an organisation that has set work structures and policies that encourage

maximum individual performance.

The next part of the project is to demonstrate a systematic approach to designing and

problem solving. This requires due research to be carried out for the relevant product in

terms of Market research, Product research and all aspects of the product that need to be

considered in order to produce a product that is satisfactory for the client, and also

conforms to relevant Health and safety regulations, and Environmental regulations.




2.2

Team Strategy on Solution Formulation

The Belbin team roles identification tool was very useful in identifying the typical

characteristics of each team member. It aided the team in allocating basic team roles as

shown in Chapter 1.1.1. Once this was achieved, the team’s main strategy to ensure a

successful outcome to the project was as follows.

1. Maintaining high level of discipline to enable effective communication and time

management

2. Encouragement of intellectual input from all members in terms of the direction to be

taken by the team and direct involvement where major decisions needed to be made

3. Intensive research into the product and customer requirements

4. Identification of the different systems within the Main Tidal Test Tank System

5. Allocation of the design of various subsystems that make up the whole tidal test tank

main system to different team members.

6. Protection of confidential information

This strategy has proved to be successful in delivering a complete project within the giventimescales.

2.2.1 Project Management Tools

Each group of people working in a team is likely to have different of managing a project. G6

Tidal Solutions employed the following project management tools to ensure that the project

was carried out to the required quality and within the given time scales.

Time Management

Microsoft Project: The group used this tool to a plan of the tasks that needed to

be carried out and the time allocated for each task.

Every Wednesday from 11am till 5pm was also set aside for carrying out work

that needed to be done in Nelson Computer Labs. This enabled a good work

environment for the group as all members were able to collaborate and carry out

work without delay.




Communication

Meetings: Meetings were scheduled for every Tuesday morning from the time

when the project began in order for the team to provide regular updates on

progress made. This also enabled regular intervals to review progress for each

task and to prioritise the most important goals on a weekly basis. It also allowed

the whole team to be aware of what each member was contributing. All meeting

minutes were recorded to show agendas and actions carried out. Relevant

documentation can be found in individual logbooks.

Emails and telephone conversations were used as a means of maintaining good

communication links amongst group members. Emails were also used for

distributing any documentation generated by the tasks carried out by each team

member.

Interviews were carried out for the stakeholders and customers identified in the

report to enable the team to have an understanding of requirements so that a

suitable design could be produced.

Group Motivation

On several occasions the team went out on social luncheons as a team building

technique. This proved to be very effective for team motivation as the team

members were able to interact together in high spirits.

Team members also proved the ability to support each other where certain

members may have needed assistance.

Project Actions

Each team member was able to contribute to the team in an exceptional manner.

Although tasks were delegated by the team manager, team members showed

great initiative by volunteering to carry out tasks they felt they would be able to

deliver. All main decisions were discussed by the team and agreed on so that

work could move on to the next tasks.

The project plan was followed and reviewed and amended depending on the

progress made by the team.




Brainstorming: The group had several brainstorming sessions in order to identify

key tasks that needed to be done. Also, brainstorming was used as a means of

identifying the customer requirements and to rank them in order of importance.

Material selection software, CAD software as well as Microsoft package software

were used to produce the bulk of the documented work generated by the team.

The design process involved coming up with designs and ensuring that primary

requirements were satisfied. The design was amended several times in order for

a practical product to be proposed to the client. Some of the designs formulated

were abandoned due to cost factors, some for health and safety reasons, and

some for not being able to meet all primary requirements.

A Shared Drive was created for easy access to group information. All meeting

minutes as well as research literature were uploaded and shared on this system

so that each member of the team has easy access to group information.




3 Research

In the engineering Industry or any other industry, every project undertaken by any

organisation requires a level of professionalism that is relevant to the industry. The main

method of ensuring that high standards of professionalism are employed in company

projects is to carry out relevant research before the project is set in motion in order to avoid

epic failures that lead to catastrophe, loss of money, and loss of market share.

3.1

Market Research

Market Research is a systematic, objective collection and analysis of data about a particular

target market, competition, and environment.

The purpose of any market research project is to achieve an increased understanding of the

subject matter. With markets throughout the world becoming increasingly more

competitive, market research is now on the agenda of many organisations, whether they

are large or small. (Definition of Market Research, 2005-2011)

3.1.1 Market Analysis

To fully understand the targeted market and to efficiently meet customer requirements,

suggestions and complaints from clients have been analysed and evaluated. Additionally,

detailed research on the project, industries and companies related to the subject has been

carried out. G6 Tidal Solutions encourages its customers to give feedback on the services

they receive in order to ensure that standards of service are at their best levels at all times.

3.1.2 Size and Trends of the Market

G6 Tidal Solutions is currently in competition with 16 organizations for the Tidal Test Tank

Project contract bid. The potential Client is the University of Greenwich. The University will

select the company which will offer the following:

Best solution

High quality service




Low-cost design

From investigations so far completed, it is possible to confirm there is a market for the

offered system. Consequently, G6 Tidal Solutions will release further production of the

system as the demand grows. Therefore, the market can be defined as a Bull Market.

A Bull Market is defined as a

financial market of a group of securities in which prices are

rising or are expected to rise. The term "bull market" is most often used to refer to the stock

market, but can be applied to anything that is traded, such as bonds, currencies and

commodities. (Bull Market, 2011)

3.1.3 Target Market

The target market of the business is small to medium sized businesses and educational

institutions around the United Kingdom that are particularly interested in Marine

Engineering and Management solutions. The company will work on a basis of submitting

proposals in response to requests by potential customers. Necessary research will also be

carried out for potential customers to ensure that the organisation builds relations with

customers that share similar business interests and policies with G6 Tidal Solutions.

3.1.4 Existing Customers

The University of Greenwich is the first client of the organisation although the clientele base

is predicted to grow as the company begins to be known and recognised by other

organisations in the Marine Industry.

3.2

Customer Requirements

Customer requirements for any project or product show detail of the customer’s

expectations from the particular product, usually in their own words. The customer

requirement information is sourced through inquiry and person to person interview with

the customer in question. The customer requirements usually, but not in all cases have

primary (very important), secondary (not so important) and secondary (can be done




without) requirements that has to be met by any service provider or product designer as the

case may be.

In some cases like a project, there may be multiple customers to make use of the same final

product. In such cases, retrieving the customer requirements is more tedious as multiple

customers are involved. This is where it becomes very important to identify the

stakeholders for the project at hand.

3.2.1 Stakeholders

The stakeholders of a project are the people that are of interest in the project; these are the

people who are affected by the main decisions made with regards to a project. The

following lists the project stakeholders identified by brainstorming

Mr Rodney Beams

Mr Peter Snelling

Students

Mr Bruce Hassan

Mr Vic Cosgrove

Mr Ian Cakebread

Dr Malcolm Butler

Professor Ndy Ekere

Commercial Port Operator

Other Technical staff

Other Universities

Local Community

These listed stakeholders were classified in their order of importance and direct

involvement with the final product. See classification schematic below of the stakeholders




Figure 4: Tidal Test Tank Project Stakeholders

The stakeholders of a project can lead to identifying the parties that have the highest

influence where the design of a product is concerned in a situation where there are multiple

customers. It is therefore important to note that “all the customers of the project are

stakeholders, but not all stake holders are customers”.

Figure 5: Customer and Stakeholder Relationship

This shows a relationship /link between the stakeholders and customers of a particular

project. The broken line shows that not all stakeholders are customers; while on the otherhand, all the project customers are stakeholders. In this project, the stakeholders who were




not considered to be customers were mostly the tertiary stakeholders. This simple

relationship and the classified stakeholders, helped in identifying the parties whose primary

requirements were priority.

3.2.2 Stakeholder Requirements

The selected stakeholders from the above classification, who were perceived to be

customers of the project, were then interviewed to obtain individual requirements that

translated into stakeholder requirements. The selected stakeholders that were interviewed

include:

Mr Rodney Beams (Main Project Client)

Mr Peter Snelling (Client Representative)

Mr Bruce Hassan (Technician)

Mr Ian Cakebread (Technical Manager)

End User (Students)

Figure 6: Stakeholder Requirements




Customer requirements can finally be drawn from the above requirements stated by each

stakeholder/customer.

3.3

Final Customer Requirements

This was done by selecting any requirements common to all the listed stakeholders, and

then taking requirements of more important customers into consideration. Please see listed

customer requirements below, not necessarily in order of importance

Test tank should be a cheap, cost effective solution

Must be simple and easy to use / operate

The tank should be capable of performing simple tidal test

Tank should be capable of simulating the tidal behaviour of another river or marine

environment

Safe for all users to operate (very important )

Easy to set up for testing

Safe location and safe working height

Reliable, durable and requires less maintenance

Capable of being self maintained

Should be physically accessible for users

The tank should have a long life span (at least 25 years)

Should provide accurate and reliable test results to users (especially students)

The diagram below is a summary of the process of determining customer requirements.

Figure 7: Flow Diagram for Determination of Customer Requirements

These customer requirements listed above are the backbone on which the project/product

design is made and completed, as the customer has to be satisfied in the listed ways. It is

important to note that the customer requirements listed could be further classified into

groups in order of importance from primary to tertiary. It should also be noted that not all




the requirements were supplied by the customer as they may not know what they want

sometimes, but know what they do not want.

3.4

Product Life Cycle

The product life cycle (PLC) of a product is the life path of the product from conception to

disposal. When a new product is conceived and introduced into the market, it goes through

a stage concept development where no profit is made as the product is not yet released to

the market. It then goes through a stage of research and development where customer

surveys and prototype development. Again, at this stage, no sales have been made yet, thus

the product is still not yet profitable. When the product has been proved to work and

relevant market research has been carried out, the product is then introduced to the

market. At the level, customers are neither familiar nor loyal to the product.

The product’s life continues into the growth stage where it begins to gain reputation and

customer loyalty. This results in increased sales volume of the product. The maturity of the

product in the market begins when the product has a good reputation and continues to see

constant sales volume. After spending some time in maturity, the product starts to see a

decline in the sales volume as a result of age, lack of improvement and even market

saturation.

Improvements to products and new market strategies at intervals when the product

experiences some decline, can increase the life span of the product. After complete decline

of the product it can be disposed appropriately. The producer can begin to change its

facilities so that it begins to produce alternative products. This pattern of product life cycle

is general for all products and can be configured to suite special situations.

The life of a product experiences changes in the marketing situation, and maybe the sales

outcome of the product as a whole may be declined. When this happens, the manufacturers

have to device a means to increase the sales volume of the product back to an acceptable

level even if not as much as the previous sales volume before the decline.




Figure 8: Product Life Cycle Diagram Invalid source specified.

The Tidal Test Tank is a one off product, but experiences the same life cycle as any other

product would, from inception, to decline and disposal. The life cycle can be suited to the

status of the test tank as a special case. Below is a schematic of the tidal test tank PLC

Figure 9:Tidal Test Tank Product Life Cycle Diagram

The sales axis of the tidal tank is represented by the product’s functions in the above

schematic. The test tank will be contracted out to the company; hence the customer for the

product is already available. This means that the product does not have to go into the

market for sale after the design and manufacture. Interestingly, in the concept and designstage, the product sees no sale (functions) as the product is not yet realised. The




introduction stage is represented by the testing and maximising the tank’s operational

functions. This involves testing the different systems that make up the product, and then

making needed adjustment so that the product is used at its optimum operation conditions.

The introductory testing stage passes and ushers in the product multiple functions provided

by the product in its operational life. This stage sees the increased functions of the product

and it represents the growth and maturity stage of the test tank. After some time of being

used, the factors of age, wear and tear on components start to show as the components of

the system start to break down. Most common examples of this include corrosion which can

further lead to failure of the critical components such as pumps and valves. This

phenomenon therefore reduces the functionality of the test tank, and marks the onset of

the product decline.

The decline of the test tank can be delayed by carrying out major service as indicated at set

intervals, or even component change, for example changing pumps every 2 or 3 years. It is

however important to note that, the service and change carried out on the tank would not

restore it to its initial level of operational functionality, as indicated on the PLC diagram

above. The decline stage can then be allowed to fully set in when the expected operational

life (about 25 years) of the product has been fulfilled or when the product becomes

redundant.

The disposal of the product after its service is very important and marks the end of the PLC.

Disposing of the tank system involves firstly assessing the extent of disposal that has to be

done. When this is completed, the components of the tank that could still be useful for

other purposes are identified and dismantled off the main system. The rest of the system

can then be dismantled, with the recyclable parts sent off for recycling and the non

recyclable parts disposed off appropriately.




3.5

Medway River Research

The purpose of the tidal test tank is to be able to mimic the tide characteristics of the

Medway River. The first step towards being able to simulate the Medway River tides was to

find out the tide behaviour of the river. The Medway river average tidal range is known to

be 5.7m (East, 2007). A study of free tide charts indicated that the highest tides in Chatham

can reach heights of 6.65m at high spring tides. (Admiralty, 2011)

Another factor to be considered is the type of water that flows in the Medway River. In

order to design as tank that holds a close resemblance to the Medway River, it is important

to also know the condition of the water that flows in the river. It would be easy to assume

that the river Medway contains fresh water. However, because it is a tidal river, it has a back

flow of sea water. This water is saltier than fresh water, however less salty than sea water.

This is known as brackish water. The water in the river becomes more salty in the direction

of the sea. The concentration of salt in sea water is an average of about 35g of salt per litre

of sea water. Brackish water ranges from 5g to 30g of salt per litre of water. (Crest, 2010)

3.5.1 Types of Ports

It has not been stated what kind of port for which the tidal test tank will be used to test port

operations. Thus it made sense to research on the types of ports that exist. There are 3

types of ports. The first is known as a closed port. An example is Medway port. This is a port

where by basins are created that are accessed by ships through locks. The water in this type

of port is kept at a constant level. As a result, the port operations within the basins are not

affected by the rise and fall of the tide. However, the ships are scheduled to go in and out of

the port depending on the tides; if the tide is too low then the ships have to wait for it to

rise again before they can leave or enter the port.

The second type of port is known as a open port. An example of an open port is Sheerness.

The water level in the port rises and falls with the tide. This means that ships have a limited

amount of time to load and unload.




The third type of port is known as a dry port. This is a type of port that is used for ship

maintenance amongst other port operations. This type of port is known as a dry dock

because the basin where the ship s contained has the water in it fully drained when the

ships are being handled.

Figure 10: Example of a closed port (Medway Ports overview map, 2011)




Figure 11:Example of an open port (Medway Ports overview map, 2011)

Figure 12: Example of a dry dock (Daniel Adamson Preservation Society, 2011)




3.5.2 Typical Test tank facilities

The different tests that a towing tank is used for tests on ship models. Such tests include

resistance tests, cavitation tests, propulsion tests and open water test amongst other tests

that can be carried out on scaled down models of ships. The most common tanks are towing

tanks that are much bigger that is required in this project. As a result it was necessary to

deviate from the normal type of towing tank designs.




4 Product Analysis

In order for any designer to be able to design a product that is required by his client, it is

important for an analysis of the product to be carried out. Such an analysis enables the

designer to identify any constraints that need to be overcome in order for the product to

have certain attributes required by the client. A designer is thus able to identify the tools

needed for a solution to be formulated with regards to satisfying customer requirements.

4.1 Functional Analysis

A product function is defined as the normal actions that are performed by the particular

device or product (WebFinance Inc, 2011). Where the tidal test tank is concerned, the

product functions would be what the tasks the tank is expected to perform and any other

functions that may come as a by-product of having the tidal test tank. An obvious function

of the tidal test tank is “tidal testing”, which could be regarded as a primary funct ion of the

product. All other functions that the tank can satisfy that are not as important as the

primary function can be considered to be secondary and tertiary functions.

On another hand, functionality is the ability for a product to perform a particular task or

function (Farlex Inc, 2011). This implies that the functional analysis of a product not only

shows the intended and possible functions of the product, but also the expected ability of

performing the named product functions.

The above named function is however not all the possible functions of the tidal tank, hence

the tank functional analysis shows all the functions of the tidal tank, both intended and

possible and also its expected capabilities in a hierarchical order of importance. The product

function analysis was obtained through interaction with the customers and by

brainstorming within the group. The functional data in table 3 was a result of the analysis

carried out.

In the above functional analysis also show functional requirements of the tidal test tank

product. The hierarchy of classification is as follows

Primary Functions: The functions of the product that are basic/necessary to its

operation.

Secondary Functions: These are not basic to the operation of the product, but are

however desired by the user with relatively less significant importance compared

with the primary requirements.

Tertiary Functions: These are desired functions that hold the least importance. They

can only be achieved when all the primary and secondary functional requirementshave been achieved.

4.2

Customer Attributes to Product Characteristics Conversion Analysis

The customer attributes are expectations of the customer in terms of requirements from

the product of interest. These attributes cannot be quantified or measured as they are

desires; hence the service provider has to determine a way to relate to the attributes. On

the other hand, characteristics are the physical properties of the product that can be




quantified/measured and therefore controlled. These then enable the designer to set limits

for the design so that the customer attributes are provided.

CUSTOMER ATTRIBUTES PRODUCT CHARACTERSITCS

5 The Solution

The product developed to be designed is a tidal test tank aimed as simulating the tidal

motion of the Medway River. The tank also has the capabilities of simulating tidal

movement of other Port environments around the world. This product will be designed to

be mostly automatic and simple to operate and use. The automated parts of the system

limit the amount of manual control by the test tank operator, making the system safe.

Different system parameters are specified in this chapter, some of which are driven by

customer requirements and also government policy. The set parameters will then be used

to design a product that satisfies the customer and the stakeholders.

5.1

The Different Solutions

After having set all the parameters that were to be designed for, a number of solutions were

formulated in order to create a test tank system capable of satisfying all basic customer

requirements. Brain storming is the main tool that was used to determine the way in which

each requirement was to be satisfied. Following brainstorming, different solution design

solution ideas were generated and were then considered one after another. The most viable

idea at a time was chosen and critically examined including the feasibility and realisation of

the solution.

This method of generation the solution to the tank design problem helped the group have

multiple design ideas that could be employed with minimal modifications as the problem

solution. When the likely design was chosen by the group, unfolding developments at the

time forced the group to review and modify the design to suite the situation, solving the

problem or eliminating it completely. After this stage and all design integrity have been met,

the design was finalised as the group’s solution to the tidal test tank project. In summary,

the design solution involved the following steps in sequence

Generate Design Ideas – Consider Ideas – Choose Design – Review Design – Finalise Design




5.1.1 Tide Simulation

In order to be able to simulate the tide movements, it was determined that the tidal test

tank would need to have a reservoir that would contain the volume of water required to

produce the rise and fall of water level in the tidal test tank. This was the main concept

around which most of the detail of the design was based on.

The next consideration was the duration of the testing times. The tide in the river rises and

falls every 6 hours. It would be very time consuming to carry out tests on a real time basis.

Also, the users of the tank, the university students, would use the testing facility during a

laboratory session. The laboratory sessions at the university last for 2 hours. It would thus

make sense to simulate a tide rise/ fall in 2 hours. Water level in the test tank would change

from high to low, or low to high in a 2 hour laboratory session.

5.1.2 Water Level Control

Having reservoir means that a means of moving water between the test tank and the

reservoir is needed. The two tanks would be arranged so that the reservoir can be at high

level, and gravity could be used to move the water from the reservoir to the test tank. A

pump would thus be used to pump water back to the reservoir. This method was not

adopted as it provided no means of a controlled flow rate of water from the reservoir to the

test tank. The flow rate of water would be highest when the reservoir is full, and then

reduce as the water level in the reservoir drops. As a result, this arrangement was not used.

5.1.3

Salinity Control

It was considered to have a dosing unit for the test tank in order to make brackish water for

the tidal test tank. The dosing unit would have a concentrated solution of brine and then be

used to make the required concentrations of brackish water in the test tank. Water

becomes saturated with salt at about at concentration slightly higher than sea water levels.

With a dosing unit at this concentration, the dosing unit would need to have a mixing tank

that is about the same size at the test tank. Consequently, this was not to be pursued for the

test tank on account of the system becoming complicated and unnecessarily costly.




5.1.4 Temperature Control

A temperature range is required for the tidal testing facility. This is 0oC to 40oC. There are

many ways in which water can have heat added to it or removed from it. The most viable

solutions formulated for this were the use of electrical heating elements to heat the water,

and to use a chiller to cool the water.

5.1.5 Test Tank Dimensions

As mentioned earlier in the report, most test tank facilities that exist tend to be very large.

In this case, research revealed that only one ship model needs to be tested at a time during

any laboratory sessions. The largest model is about 2m long. The tidal test tank needs to be

able to accommodate such a model, so its’ length is to be no less than 2.5m.

5.2

Quality Function Deployment

The quality function deployment (QFD) is a visual decision making tool which shows how

existing and proposed solutions for a certain application are matched with customer

requirements (WebFinance Inc, 2011). It transforms the customer requirements into design

quality which can be used to deploy functions to meet that stated design quality. The QFD

matrix is also known as the House of Quality (HOQ Matrix) and is comprised of various

rooms interacting with each other to make up the entire house.

The rooms are Customer Requirements: this is where customer requirements are represented in

their own words.

Planning Matrix: this room shows how existing products including this company’s

product fairs with the named customer requirements.

Technical Requirements: this room is also known as the engineering characteristics.

The information here is developed by the design team who identify the measurable

characteristics of the product that are related to meeting the customer

requirements.

Interrelationships: this is the main body if the HOQ matrix and it identifies the

relationship between the customer requirements and the technical requirements.

Roof: this identifies the areas where the technical requirements that characterise the

product support or impedes one another.

Targets: this is the last room in the HOQ matrix and it summarises the data

contained in the other rooms and final design targets.

Having identified QFD as a viable quality tool, the group decided to carry out a QFD analysis.

The illustration in figure 14 is the result of the QFD analysis carried out by the group to

check the quality and integrity of the design. Have such a QFD analysis, the group can

determine the acceptance of the product by providing customers with what they require,

hence avoiding failure.

As a summary, the group took careful solution steps in a systematic sequential order to

achieve the optimum solution to the problem at hand. See the schematic below for a

summary of the solution tools used by the group to achieve the final solution

5.3

Quality Assurance Management System

In order to develop a quality product, the company has established an effective quality

management system. The foundation of a quality organisation is the concept of the

customer and supplier working together for their mutual benefits; consequently the

customer-supplier interfaces are extended into and outside the organisation.

Quality Management System will help to direct and control the business in order to

continually improve the effectiveness and efficiency of its performance.

Thanks to this system two basic requirements will be met:

Customer’s requirements: confidence in the ability of the organisation to deliver the

desired design and service consistently meeting their needs and expectations

Organisation’s requirements: efficient use of the available resources at an optimum

cost

Quality Management Systems are used in all sectors of the business and it will:

Set direction and meet customer’s expectations

Improve process control

Reduce time and wastage

Lower costs

Increase market share (QUALITY MANAGEMENT SYSTEM (QMS) STANDARD, 2011)

5.3.1 Standards

The following standards will be used to monitor the quality of the product and service:

ISO 9000: 2000 – Quality Management Systems – Fundamentals and Vocabulary

ISO 9001: 2000 – Quality Management Systems – Requirements

ISO 9004: 2000 – Guidelines for Performance Improvement

ISO 1400 – Environment Management Standard (Summers, 2000)




These standards are built around business processes, with a strong emphasis on

improvement and a focus on meeting the needs of the customers. In fact, the family of ISO

9000 contains eight quality management principles, upon which to base an efficient,

effective, and adaptable QMS, which are applicable throughout industry, commerce and

service sectors:

Customer Focus

Leadership

Involving People

Process Approach

Systems Approach

Continual Improvement

Factual Decision Making

Mutually Beneficial Supplier Relationships (Quality Management Systems, 2011)

5.3.2 Ergonomics

The Company in order to develop a quality design has followed these standards:

ISO 7250: 1996 Basic Human Body Measurement for technological design

ISO/TR 16071: 2003 Ergonomics of Human System Interaction- Guidance on

Accessibility for human-computer interfaces

The design has been constructed for members of user population who fall between the 5 th

and 95th

percentiles in any particular respect; hence 90% of users are accommodated within

the design limits. (Pheasant, 1998)

5.3.3 Quality Costs

Using Quality costs, the company is able to determine the usefulness of investing in process,

changing a standard operating procedure or revising a product or service design.

Quality costs are categorized into following sections:

Prevention Costs: Costs which occur when a company is performing activities

designed to prevent poor quality in products or services

Appraisal Costs: Costs associated with measuring, evaluating, or auditing products or

services to make sure that they conform to specifications or requirements

Failure Costs: Costs which occur when the completed product or service does not

conform to customer requirements (Summers, 2000)

Intangible Costs: Hidden costs associated with providing a nonconforming productor service to a customer, which involve the company’s image as well

Process Flow Design

Figure 18: The path taken by water in the system




The Process flow design illustrates the path taken by the water when it is moved for the

tidal simulations.

On initial set up, the main test tank will be filled to the High Water Level from the mains in

order to provide the full volume of water required in the system which is about 3000 litres.

Water from the test tank will be fed to the reservoir by means of gravity through an

actuated control valve. The control valve will limit the flow rate to required amounts. The

reservoir is only large enough to hold the required movable water to create tide simulations

in the tide testing facility. The volume of movable water needed for tidal rise and fall in the

test tank is 1800 litres. This amounts to a low and high level of 0.2 m and 1 m respectively.

When the reservoir contains water at the High Water Level (HWL) mark (0.45m), the test

tank is at Low Water Level (LWL) (0.2m), which is the lowest water level allowed in the test

tank. When water in the test tank is at the HWL mark, then the reservoir is at its LWL mark.

From the reservoir, water is moved by a single phase pump at full speed through a flow

reducing throttle valve. At this point, any excess water from the pump is sent back to the

reservoir, and the required flow rate is sent directly to the test tank. Alternatively, water can

be fed to the test tank via the chiller when the water needs to be chilled.

When water reaches the LWL in the reservoir, a switch is triggered in the reservoir that

stops the pump, preventing overflow in the test tank and potential damage to the pump.

This means that the test tank is full and the test tank is at HWL. At this level, the actuated

valve at the test tank outlet can then be opened so that it begins to feed water back to the

reservoir. Then when water reaches LWL in the test tank, the actuated valve is commanded

to shut fully.

When the water reaches the HWL in the reservoir, a switch is triggered that will start the

pump so that it feeds water to the test tank. This means that the system can run tide cycles

automatically whilst the user carries out measurements. The automatic cycles range from 2

hours to 6 hours depending on the set flow rates for the experiments. The flow rates can be

set on the Labview PC.

Control system Design

The test tank is designed to simulate tidal characteristics in real and scaled time as

required. Also to be controlled by the test tank are the water salinity, water temperature

and water flow rate. These requirements necessitated the design of a control system to

monitor and control the named parameters. In the process of designing this control system,

different control techniques came up and were briefly investigated to choose the best

option. They are

Mechanical Control: This involves the use of mechanical instruments to monitor andcontrol the said parameters. For example, using a hydrometer to measure the

salinity of the water.

Instrumentation: This involves the use of electronic instruments that have been pre-

programmed to measure and possibly control certain quantities.

Electronic Programmable Circuits: Sensing instruments are employed and controlled

using self programmed electronic circuits.

Figure 19: Control Technique Comparison




6.3.1 Control System

The schematic above was used as a comparison tool between the three control techniques.

Instrumentation was chosen to be used in the control system design. This meant that

sensors and similar instruments to measure control the stated quantities had to be selected

in the process of designing the control system

Figure 20: Control System Design Process (Dorf & Bishop, 2005)

The above design process was followed to select the necessary instrumentation in the

process of designing the control system. The goal of the control system, was to achieve a

fully or semi automatic control of certain quantities. The important quantities to monitor

and control were

Water Temperature

Water Salinity

Water Level

Water Flow Rate




The listed quantities can be monitored and controlled using electronic instruments and

sensors. The sensors can only be selected by carefully determining the requirements it has

to meet in terms of performance, dimensions, protection against adverse conditions etc.

These considerations were used to write up a specification for the level control sensor.

RATED OUTPUT ±5 VDC The output of the transducer should be a

reasonable DC voltage signal to allow for accurate

measurement

RESOLUTION 0.05 m The transducer must be capable of measuring small

level changes of at least 0.05 m, to have more

sampled level data and accuracy

SUPPLY VOLTAGE 5 – 15 VDC Transducers usually require excitation voltage to

operate

MAXIMUM MASS 0.75 Kg Low mass is a desired if the sensor will be placed in

the tank. There would be no distortion of results

CONTROL PROGRAMMABLE The sensor should be capable of being programmed

further to aide with overall system control and data

manipulation

PROTECTION CLASS IP58 Minimum The transducer must be protected against salt and

other particles. It should also be protected from

continuous immersion in water

Table 7: Level Transducer Specification




The specification was used to search for suitable level transducers for the control system.

Two transducers were identified and reviewed

1. Flowline Inc’s Echopod which uses ultrasonic means of sensing, to switch and

control the level as desired

2. Honeywell Limited’s LLE Series optical sensor, which uses infrared technology to

sense and transmit result to the controller

The two transducers were reviewed and the Honeywell optical level sensor was chosen for

the control system. Some of its features include

Small size, thereby needing less space

Digital output

Microprocessor compatible, hence programmable

Pre-wired

The above specification writing and selection method was implemented for the other

sensors and instruments and equipment used in the control system. A list of the selected

instruments and equipments can be found later in this report. The instrumentation

schematic in figure 19 shows the interaction between the sensors in the system

The chiller is shown independent on the schematic as it will not be automatically controlled

from the PC interface like the other sensors and equipment. The sensors in the control

system are to be strategically placed inside or outside the test tank as required by their

function. The measured parameters are sent back to the PC interface via hardware USBinterface. The Labview PC software interface will be used on the control panel to monitor

and control and output and inputs of the sensors in the system.

Below is the WBS for the control system. It shows the manner in which the various control

sub-systems interact in a hierarchical order. This can also be used to represent the control

system’s bill of materials (BOM) as it will have the same content in this case only.

Electrical Systems Products and Design

An electrical system plays a significant role in the tidal test tank system. Several electrical

components have been selected based on the main supply voltage. A single phase 240V/ac

is set out as a main supply. On the basis of this restriction the components have been

selected to meet the requirements.

6.4.1 System Requirements

Control Panel: The control Panel is mainly used for the purpose of controlling the

system as a whole. Therefore the control panel will need to have several

characteristic and parameters.

single phase centrifugal pump.

Technical Parameters

Single Phase

Voltage : 240 Volts AC

Frequency : 50 Hz

Protection : Single Phasing,

Over Load and Short Circuit

Relay Type : Thermal SPST




Transformers: A transformer is used to step down the voltage to the required output

voltage for several components within the system, due to their operating voltage

characteristics.

Voltage Regulator AC to DC: Several components are operating at a lower voltage

than specified, therefore AC to DC conversion will be required in order for the

components to operate accordingly

Wiring Cables: Different types of electrical wiring cables are used depending on the

components operating parameters. The length and diameter each cable will changebased on the operating voltage and current of each component.

Relay Switch: The relay switch is used as a circuit break from the main control panel.

5 relay circuit breakers will be required to protect the component from overload or

short circuit.

6.4.2 Electrical System Design

A design has been carried out based on the system requirements. As shown in Figure 12 the

control panel consists of 5 relay circuit breaker to protect all the components used.

Primarily one relay will be used to operate the water level sensor, temperature sensor, and

flow sensor because their operating voltage falls between 4.5 -12V/DC. Hence a transformer

is utilised to step down the voltage from 240V AC – 50V AC. Additionally, because the

sensors are operating on DC characteristics, a voltage regulator is required for the

conversion of AC to DC. The pumping system will use one relay circuit breaker given that it is

operating at 230V AC at 3.3A. Furthermore, the pumping system will have its own

Emergency Stop Push Button (ESPB) in case of a malfunction in the pumping system.

Other components such as water heater, Digital thermostat, and water chiller will have their

individual relay circuit breakers. These components will not require transformer or voltage

regulator since they are operating above 230V AC.




Moreover the value readings from the water heater, Digital Thermostat, water level sensor,

temperature sensor, and flow sensor are ought to be interfaced to a PC using a standard

USB cable.

7 Manufacturing Plan

The time and cost of manufacturing systems is affected by the uniqueness of the components that

it comprises of. G6 Tidal Solutions proposes a design that consists mainly of standard components.

This means that the test tank, the reservoir, sensors, and all other parts of the testing facility can be

purchased “off the shelf” from various suppliers. This then gives the advantage of reduced lead

times and also guarantees that components can be sourced and easily replaced once the testing

facility becomes operational.

Detailed plans have been made by the company to manage the time and cost effectively. A Gantt

chart showing the time estimation for project implementation and realisation if given the chance in

the way of a contract by the client is shown below

Figure 24: Project Implementation Gantt Chart (Time Estimation)

The above chart shows a total of 70 working days the company estimates for completion of the

project if given the contract by the client. This translates to 4 months and 2 weeks to finish up the

project and have the product running and ready for the customer. It is important to note that this




time given is only an estimate and should be treated as such as other factors like public holidays,

supply chain difficulties, labour work difficulties and similar problems can prolong the stated time

to deliver the final product to the customer.

Also detailed below is a network analysis of the tasks required to realise the project for the client as

desired. This was derived from the estimate Gantt chart above

7.1

Supply Chain

Seeing as most of the product is made of purchase components, A supply chain analysis has been

carried out in order to identify the links within the supply chain. This is also important as it enables

G6 Tidal Solutions to formulate a supply chain strategy that will allow for the project to be a

success.

Table 11: Table of Costs

The stated costs will be subject to change as the project goes through to completion. Finally, the

company has decided to adhere to high quality standards to keep out clients satisfied has in the

way also created a prolonged time to realise the project at a high cost as well. According to the

company’s method, the long time the project follows cannot be shortened, or costs reduced




without a direct negative impact on the impact on the quality of the project outcome. This

compromise can only be made by the customer if they require services to be done at a shorter time

and possibly cost.

9.3

Electrical Health and Safety

Working with electrical equipment is made safe by carrying out suitable checks, such as inspection

or testing on all electrical equipment and components to ensure that they are in suitable working

condition. The level of inspection or testing should depend upon the risks. It is hazardous for to

work within areas with unprotected live wires.

The most common hazards that occur with electrical equipment or installation are as follows:

1. Poor maintenance of electrical equipment

2. Exposure to mains electricity supplies where UK currently supplies 240volts

3. Incorrect use of electrical equipment in potentially explosive areas

4. Poor electrical installations and faulty electric appliances are often the root cause fire

accident.

5. Avoiding of any contact with live parts causing shock and burns

6. Fixed electrical installations should be inspected and tested by a competent person at least

every three years.

7.

A test certificate confirming the date and results of the inspection and test should beprepared and displayed at all time.

8. Precautions against the risks caused by flammable or explosive hazards, electrical

equipment.

9. Electrical shock hazards: All persons should not touch electrical controls in a tank area, such

as a pump power, electrical switch; when standing on a wet floor as this can be fatal.

The client is recommended to take necessary measures to avoid such hazards and

any life threatening hazards related to working with electricity that may not be

mentioned in this document.




9.4

Platform Health and Safety

The work platform is provided with guard rails and toe boards

The platform is not to hold more than 8 persons working on the testing facility

Guard rails are provided to avoid falls due to working at height

Steps are there for access and regress to the platform

It’s suitable to be carried test before being used and inspected at least once a month to

prevent any crack forming, defects or any loosen bolts.

Any person working with the platform area should always wear relevant personal protective

equipment such safety boots, visible vest, cap, gloves were applicable.

Students working around the platform should aware of the safety issues that arise with

working at height

Workrooms must be big enough to allow easy access of movement within the platform

area.




9.5

Health and Safety Life Cycle

The diagram below shows how health and safety hazards can be identified through a cycle. A

systematic approach is essential and is based on the four steps of identifying hazards, assessing

risks, applying controls and reviewing their effectiveness.

Figure 28: Health and Safety Cycle (Phil Hughes, 2009)




10 Services

A good consultancy company provides solutions for its clients either by designing new products or

by designing modifications to the client’s already existing equipment. An excellent consultancy

company continues relations with customers after implementing solutions by recommending

methods of best practice as well as good maintenance plans. G6 Tidal Solutions offers this service

to all its clients.

10.1

Maintenance Program

G6 Tidal Solutions an organization that is committed to provide an excellent maintenance service by

providing prompt responses to problems faced by customers. As shown in the Product Life cycle, all

equipment starts to deteriorate with time and use. It is therefore necessary to be able to

recommend maintenance programmes that would enable the product’s lifespan to be lengthened.

That way, the client is able to use the equipment as long as possible.

10.2

Tank Maintenance

The main tank is made of 40% glass fibre ABS material. This material has good resistance to

chemical attack; however it is not immune to degradation caused by:

Visible light

Ozone and other extraneous pollutants

Intrinsic manufacturing impurities

Oxygen

Heat

Consequently deterioration-fighting chemicals are added to the material during the manufacturing

of the product. Moreover to extend the life span of the product, dirt and grime can be cleaned with

distilled or deionised water and strains can be removed with a non-ionic detergent. It is advisable to

avoid using solvents, as the material is likely to have a strong reaction to the solvent leading to

cracking to the product. (Restoring plastic based items, 2011)

It is also important to check for leaks periodically. The tank is made up of separate panels. Although

a sealant is used within the joints, leaks may be experienced in areas where the sealant is not




evenly distributed, or simply where the sealant has failed. Another area to regularly check for

leakages is in joints where the tank is joined to pipes and instruments (Brown, 2011). The test tank

will be containing salt, so it would be advisable to rinse out the tank with fresh water when it is fullydrained to avoid a build up of salt crystals on the walls of the tank.

10.3

Reservoir Maintenance

The reservoir is made of the same material as the tidal test tank. It would then have the same

maintenance routine as the tidal test tank. The reservoir would require occasional freshwater

rinsing to remove salt crystals. A routine check for leaks can be coincided with that of the Tidal test

tank. Focus should be made on the joints and connection for pipes and instruments.

Cracks and other signs of fatigue can be checked for every 3 years. It is important to do this as the

tank experiences cyclic loading by the pressure exerted on its walls due to the rise and fall of water

level.

10.4

Components Maintenance

Every system is as robust as its weakest component. It is therefore important to recognise that

practicing the best methods of operation includes carrying out the relevant and necessary routine

and long term maintenance procedures for the various parts that make the entire system.

10.4.1 Sensors

These can be considered to be consumables. This means that they can be replaced when they cease

to perform their required function.




10.4.2 Pump

The pump is one of the key components of the system, thus it is of great importance to keep it well

maintained. It is recommended to flush it with fresh water when it completes its service with saline

water. This will prevent the collection of salt crystals in the pump, and lengthen its lifespan. The

pump is a component that will not have the same lifespan as the tank. Consequently, every time a

main overhaul is carried out, the pump may have to be replaced, depending on its condition at the

time when the planned maintenance occurs.

10.4.3 Valves, Pipes and Fittings

The valves and pipes can be subject to clogging due to scale built up. It is recommended to de-scale

them at set intervals of the year in order to maintain high system performance.

10.5

Platform Maintenance

The platform will be used by people. It is therefore recommended that the platform be inspected

on a monthly basis to ensure that it is intact for health and safety reasons. Inspected platforms

should be tagged accordingly to ensure that they do not fail when they are in service.

10.6

Breakdown

The Tidal Testing facility has been designed in a way that avoids complete system breakdown. Each

part of the system can be independently dismantled. This enables maintenance to be carried out on

specific areas of the testing facility without disassembling the entire system.

10.7 Recommended Planned Maintenance Schedule

During the operational phase, Tidal Test Tank is recommended to be overhauled every 3 years for

inspection and repairs of any components demonstrating reduced performance.

Machinery maintenance takes place periodically when the tidal test tank is in operation. Important

environmental aspect to take under consideration is:

Discharges

Waste Management and treatment

Noise and dust emission




11 Environmental Impact and Consideration

Designing waste disposal facilities that meet the environmental rules and regulations is a complex

task because of the large number of factors that influence waste. As a result, customers are

becoming mindful of the way in which their operations affect the environment. An Environmental

Impact Assessment is required for any project that is likely alter the environment significantly.

Planning authorities require the developer to produce an environmental statement including.

A description of the development and data on the main impact it is likely to have on

the environment

A description of the likely significant environmental impacts including direct and

indirect impacts

Impact on human beings

Impact on landscape and cultural heritage

Reduce

Reuse

Recycle

Responsible

Disposal

Figure 29 :"Reduce, Reuse, and Recycle" Waste management (the 2e element)

11.1 What are the overall impacts on the environment from the project?

The project may have some significant impacts on the environment due to the use of excessive salt

water which needs to be disposed at least once every six month. In addition at the end of the

materials product’s life cycle and how it is disposed may play a significant role on the environment.




11.2

Trade effluent

Trade effluent is any liquid waste that is discharged from premises being used for a business, trade

or industries. This project in particular has considered two methods of disposing systems due to

the involvement of relatively large amount of salt water effluent involved. On the one hand, salt

water can be disposed of via waste disposing companies. A contract can be made with companies

to collect and dispose salt water on regular intervals of the year. A potential company that would

be suitable for this purpose is Envirogreen. On the other hand, salt water can be disposed of using

the mains sewerage system. However this option requires certain regulations to be obeyed by the

company or the user responsible for discharging trade effluent to a foul sewer. These are explored

later in the report. Some of the factors of concern where large volumes of salt water are being

disposed of in the sewerage are:

Damaging the sewers

Damaging the sewer treatment works

Cause a health hazard for sewerage workers or the general public

Harm the environment

11.2.1 Water Pollution Regulations

It is important to be aware of the effect of water pollution when disposing salt water. It can be

considered as a substance which capable of entering surface waters or groundwater. The following

legislations have been used as a guide to the way in which G6 Tidal Solutions recommends for salt

water disposal.

The Anti-pollution Works Regulations 1999 water resources, England and Wales No. 1006

The control of pollution ( Applications, Appeals and registers) regulations 1996

The Hazardous Waste Regulations 2005 (which implement the provisions of the European

Hazardous Waste Directive 91/689/EEC) provides a consistent definition of Hazardous

Waste and ensures environmentally sound management and regulation of such waste.




11.2.2 Saltwater Disposal

Several investigations have been made to find a solution for the problems outlined above. Hence it

is important that the company or the user complies with the restrictions regardless of how much

trade effluent is been discharged. Hence there needs to be a trade effluent agreement with the

local water and Sewerage Company before discharging any trade effluent to the sewer.

Disposing salt water via waste disposing companies will depend upon the user’s location, how the

chemical is contained as well as the type of chemical that needs to be disposed. In this case, the

effluent is 3000l of brackish water, with a potential maximum concentration that reaches seawater

levels. From the research carried out it has been concluded that to collect and dispose of hazardous

wastes, there is a minimum collection charge of £320.00 including VAT (Envirogreen).

Having listed out the environmental problems and solutions previously, it is important to outline

the responsibilities of the general user of the product as follows

Notification and registration to relevant authorities

Selection and approval of specialist contractors for the disposal of Hazardous Waste

Provision of advice to Schools and Departments regarding classification of Waste Schools

and Departments are responsible for

Ensuring they have systems for risk assessment, identification, and suitable packaging

available for the management of Hazardous Waste

Monitoring that staff, students and contractors are following the necessary systems Staff,

students and contractors are responsible for

Staff contractors who generate hazardous waste are responsible for ensuring that it is

packaged properly




11.3

Disposing Tank Materials

According to the product life cycle the tank and any other component parts related to the tank will

be dismantled and disposed of, or reused for other purposes.

11.3.1 Reusing Components in the System

Once the product has fulfilled its purpose, some of the components may need to be reused for

suitable applications. The following components could possibly be reused depending on their

operating conditions and the state they are in when the product has reach the end of its estimated

lifespan.

Pump

Sensors

Pipes PVC material

GFRP reservoir

There are some advantages in that some components, such as the sensors, have no direct contact

with the salt water hence the likelihood of damaging them is low compared to the pump. The pumpis exposed to the salt water during laboratorial operations. Also the effects of salt water on PVC and

stainless steel materials are insignificant.

Figure 30 End-of-life FRP Components

As mentioned above some components may need to be reused on the bases of their functionality.

However when recycling or disposing large amounts of materials some legislation may need to be




considered. As the waste Framework Directive requires that the waste to be classified by the type

and the purpose of its use, Generic Fibre Reinforced Polymer (GFRP) waste can be classified under

several codes of the EU waste list as follows

Frame work Directives (75/442/EEC) in 1975

Additional related document including 91/156/EEC

European waste list (commission Decision) 2000/532/EEC

11.3.2 Complete Disposal of the System

Alternatively, if there is no usable application for the components in the system, complete disposal

is the only remaining option. There are different regulations and requirements for the disposal of

materials such as GFRP, pipes, fittings and valves, and for the disposal of electrical components

such as pumps and sensors and the PC.

The estimated cost for incineration of GFRP is £120 to £150 per tonne (National Composites

Network). Other components in the system

APPENDIX 5 – SALT WATERCREATION




Water Salinity

The Medway River contains brackish water as mentioned before. The salt content in the

water consists of a wide variety of salts and not just sodium chloride. As a result, it has been

decided that marine salt can be used in order to provide the Medway Estuary conditions.

The salt content in brackish water ranges from 5g of salt per litre of fresh water, to 30g of

salt per litre of fresh water. However, to allow for more flexibility of testing conditions,

calculations have been made so that the salinity in the tank can range from fresh water

conditions to sea water conditions.

Instructions for making the salt water in required concentrations from fresh water

1. Ensure entire system empty (test tank, pipe work and reservoir)

2. Make sure all valves to and from the test tank are closed

3. Half fill the tidal test tank ( to the 1500litre mark) with fresh water from the mains

source

4. Raise water temperature to about room temperature.

5. Add the required salt i.e. 5kg to 105kg of salt. Do not handle more than 25kg of salt

at a time.

6. Evenly distribute the salt in the tank to avoid creating a lump of salt collecting one

section of the tank

7. Allow the salt to dissolve till the water is saturated

8. Add the remaining fresh water in intervals, allowing the salt to mix in the water

9.

Fill the tank to the 3000litre mark

10. Check if salt is completely dissolved then distribute the water to the reservoir.

Low Concentration to High Concentration salinity

Example, if concentration is at 10g/l then 30 kg of salt is already in the water, to increase

salinity to 25g/l, simply add a further 45kg of salt to the water in the test tank and allow it to

dissolve




Volume of water = 3000litres

Concentration [g/l] Density[kg/m3] Salt Requirements [kg]

25 1025 75

30 1030 90

35 1035 105

Table 12:Table of salinity concentration converted to salt requirements

Suppliers

This is a table of possible suppliers that can be used for the supply of bulk sea salt. If the

same supplier is used on a regular basis, then a contract can be set up in order to reduce the

cost of the salt per unit mass.

Salt Supplier Cost Contact

Kent Reef Salt Coventry Aquatics £1.90 per Kg Tel: (024) 7650 3050

Instant Marine Salt 123 Aquatics £2.00 per Kg Tel: (017) 3346 8677

Sea Salt Summer Naturals £0.90 per Kg Tel:(016) 1338 2256

Red Sea salt Amazon £1.97 per Kg Amazon.co.uk

Caution:

Health and Safety regulations;

o Do not lift more than 25kg of salt at a time.

Allow salt to fully dissolve in the test tank before distributing water through the

piping and pump system to avoid moving solid salt particles.

Note: Evaporation of water from the test tank due to warm conditions in the testing

environment can lead to higher concentrations of salt water as the water evaporates into

the atmosphere.
