INTRODUCTION

General

Although the ship is supplied with shipbuilder's plans and manufacturer’s

instruction books, there is no single handbook which gives guidance on

operating complete systems as installed on board, as distinct from individual

items of machinery

The purpose of this manual is to fill some of the gaps and to provide the ship’s

officers with additional information not otherwise available on board It is

intended to be used in conjunction with the other plans and instruction books

already on board and in no way replaces or supersedes them

Information pertinent to the operation of the vessel has been carefully collated

in relation to the systems of the vessel and is presented in three on board

volumes consisting of CARGO and DECK OPERATING MANUAL, BRIDGE

OPERATIONS MANUAL and MACHINERY OPERATING MANUAL

The Cargo Operating Manual and the Machinery Operating Manual are designed

to complement MARPOL 73/78, ISGOTT and Company Regulations

The vessel is constructed to comply with MARPOL 73/78 These regulations

can be found in the Consolidated Edition, 1991 and in the Amendments dated

1992, 1994 and 1995

Officers should familiarise themselves with the contents of the International

Convention for the Prevention of Pollution from Ships

Particular attention is drawn to Appendix IV of MARPOL 73/78, the form of

Ballast Record Book It is essential that a record of relevant ballast operations

are kept in the Ballast Record Book and duly signed by the officer in charge

In many cases the best operating practice can only be learned by experience

Where the information in this manual is found to be inadequate or incorrect,

details should be sent to the British Gas Technical Operations Office so that

revisions may be made to manuals of other ships of the same class

Safe Operation

The safety of the ship depends on the care and attention of all on board Most

safety precautions are a matter of common sense and good housekeeping and

are detailed in the various manuals available on board However, records

show that even experienced operators sometimes neglect safety precautions

through over-familiarity and the following basic rules must be remembered at

all times

1 Never continue to operate any machine or equipment which appears

to be potentially unsafe or dangerous and always report such a condition immediately

2 Make a point of testing all safety equipment and devices regularly Always test safety trips before starting any equipment Test as per the requirements of the BG Group QA system

3 Never ignore any unusual or suspicious circumstances, no matter how trivial Small symptoms often appear before a major failure occurs

4 Never underestimate the fire hazard of petroleum products, especially fuel oil vapour

5 Never start a machine remotely from the control room without checking visually if the machine is able to operate satisfactorily Auto standby machinery should be checked by observation during duty rounds

In the design of equipment and machinery, devices are included to ensure that,

as far as possible, in the event of a fault occurring, whether on the part of the equipment or the operator, the equipment concerned will cease to function without danger to personnel or damage to the machine If these safety devices are neglected, the operation of any machine is potentially dangerous

Description

The concept of this Machinery Operating Manual is to provide information to technically competent ship’s officers, unfamiliar to the vessel, in a form that is readily comprehensible and thereby aiding their understanding and knowledge

of the specific vessel Special attention is drawn to emergency procedures and fire fighting systems

The manual consists of a number of parts and sections which describe the systems and equipment fitted and their method of operation related to a schematic diagram where applicable

The first part of the manual details the machinery commissioning procedures required to bring the vessel into varying states of readiness, from bringing the vessel to a live condition through to securing plant for dry dock

The second part details ship’s systems, providing a technical description, system capacities and ratings, control and alarm settings and operating details

Part three provides similar details for the vessel's main machinery control system

Part four gives operational emergency procedures for the use of essential machinery

Part five details the emergency fire fighting systems incorporated on the vessel, providing information on their operation and system capacities

The valves and fittings identifications used in this manual are the same as those used by the shipbuilder

Illustrations

All illustrations are referred to in the text and are located either in the text when sufficiently small or above the text on a separate page, so that both the text and illustration are accessible when the manual is laid face up

Where flows are detailed in an illustration these are shown in colour A key of all colours and line styles used in an illustration is provided on the illustration Details of colour coding used in the illustrations are given in the illustration colour scheme

Symbols given in the manual adhere to international standards and keys to the symbols used throughout the manual are given on the symbols pages

Note: Notes are given to draw the reader’s attention to points of interest or

to supply supplementary information

1.2 To Prepare Main Plant for Operation (Raising Steam)

Allow the fuel temperature to rise to approximately 90°C Purge the boiler furnace

When the purge sequence is completed, flash the boiler and adjust the air and fuel to the minimum for good combustion

(Note: The length of time the boiler has been

out of operation governs the amount of time to allow for raising steam The longer the unit has been off line, the greater the number of flashes and soaks should be allowed, before continuous firing.)

3.3.3

Slowly raise the steam pressure At approximately 1.0 - 1.5 bar and with steam emitting from the steam drum vent, close the vent valve

3.3.3

Continue to raise the steam pressure, closing in the various drains as required to maintain good drainage without excessive water loss

2.11.2

Once loading arms are confirmed as

disconnected, commence raising the main

steam line pressure to the main turbine by

slowly opening the bypass valve on both boiler

main turbine stop valves

2.2.1

At the emergency manual manoeuvring valve position, turn the main turbines in the ahead and astern directions a couple of times and confirm all equipment is in good order

Set the emergency manual manoeuvring valve back to the neutral position and reset the main turbine trip

With the manoeuvring controls in manual mode, from the ECR with some attendance at the turbine side, operate the control to allow main steam into the turbine and rotate ahead at approximately 5 revolutions per minute

Repeat for astern movement

While the above is being undertaken, the mainturbine is checked to ensure it turns satisfactorily

3.4.2

Check and inspect the steering gear systems, ensuring the LO levels and hydraulic oil levels are correct

As each unit is tested, check all movements of the rams and rudder are satisfactory and as required Maintain contact with the bridge as these tests are undertaken

(Note: When steering gear tests are completed,

to prevent the pumps delivering in the same mode for long periods and risk overheating the unit, ensure the deck officer alters the rudder angle regularly to overcome this.)

2.10

Open the main boiler's superheated steam stop valves to the main turbine once the main steam line pressure is at normal

2.1.1

Disengage the turning gear

Advise the bridge that the main turbine will be operated and confirm that the propeller area is clear

Trang 30

When the temperature differential between the boiler superheater outlet temperature and the manoeuvring valve inlet temperature is greater than 30°C, the steam pipes have not received sufficient warming time When this is the case, attention must be paid to avoid excessive HP turbine vibration

When this temperature differential is present and the engine is at half ahead or greater speed, the HP turbine vibration levels must be monitored until the temperature differential has disappeared

If the HP turbine vibration level is above 20 µm/

s, the level must be constantly monitored

If the HP turbine vibration level increases above 30 µm/s, the engine revolutions must be decreased sufficiently to reduce the vibration level below 10 µm/s

3.4.1

Reset the main turbine trips and confirm that the control oil and lubricating oil pressures are normal

Using the controls in manual mode, repeat the ahead and astern movements to warm through the turbine to a superheat temperature approaching that of the boiler

3.4.2

As required by international rules, ensure all the information concerning the above being carried out is recorded along with the times at which each section is completed

Inform the bridge that the main engines areready for use

At standby, put the main turbine controls tobridge control mode and monitor their response

as manoeuvring proceeds

3.4.2

The Main Turbine is Now Ready to Put to Sea

Trang 31

The main scoop inlet valve opens and the main sea water circulating pump stops

With the scoop system in use, ensure that the main condenser temperature and vacuum are maintained

is available

2.6.3

Confirm the automatic stop of the main turbine standby auxiliary LO pump and that all LO pressures remain normal

Pump the contents of the bilge tank overboard through the oily water separator unit Note that MARPOL regulations apply

Manually change over the operating mode switch from manoeuvring mode to normal mode

Record the following:

Time Main engine revolution counter reading Fuel oil counter reading

Fuel oil service tank levels Diesel oil service tank level Fuel and gas oil bunker tank levels Gas flow meter reading

Confirm that the astern guard valve is closed, the main turbine drains are automatically closed and the main feed water pump automatic recirculating valve is closed

Allow the main engine revolutions to increase

as per the timed program, which will open the manoeuvring valve a set amount over a period of time until it is fully open This will take approximately 40 minutes from full ahead manoeuvring revolutions to full sea revolutions

3.4.2

1.4 To Change Main Plant from Manouvring to Full Away

Trang 32

Remove one turbine generator from the main switchboard, allow it to run light for a few minutes to cool down.

(Note: It is possible to test the turbine generator

trips while the unit is in this condition.)

2.12.2

Stop and isolate the off load turbine generator

With the turning gear engaged allow the generator to rotate with the electric LO pump in use until cool

2.11.1

Ensure that the live steam make-up valves close and the main turbine bleed steam valves open

as the main turbine revolutions increase

Check that the changeover of the LPSG heating steam, from live to HP bleed, has occured

Confirm with the bridge that the boilers may be soot blown and proceed as appropriate

When full sea speed has been achieved, make final adjustments to the plant to give optimum performance at the required speed

Refer to the heat balance diagrams

Revolutions

Approximately 2 hours before manoeuvring

operations are to commence, run up the standby

turbine generator

(Note: Trips may be tested at this time.When

the unit is up to speed, parallel with the unit

already on the main switchboard.)

2.11.1

2.12.2

Approximately 1 hour before manoeuvring

operations are to commence, request the bridge

to bring the telegraph position to standby full

ahead rpm gradually on the telegraph vernier

over 40 minutes The revolutions will be at the

standby full ahead

3.4.2

As the main turbine rpm and the bleed steam

pressures reduce, ensure the automatic

valves close and the make-up valves open as

required

If the main boilers are on BOG burning only,

change to dual fuel burning on both

Ensure that the main circulating pump starts, the valve opens and the scoop valve closes This ensures the correct amount of cooling water

to the main condenser is maintained as the vessel’s speed drops

As the main turbine revolutions reduce, the operating mode select switch will automatically change over to manoeuvring mode

At manoeuvring rpm, the astern guardian valve opens, the turbine drains open and the feed pump recirculating valve opens

As the turbine rpm continues to fall, the main condensate recirculation valve will open

This allows condensate to return to the main condenser hot well, ensuring a level is maintained for the condensate pumps

Shut down the evaporators, unless only distilled water is required to be manufactured

2.14.1

When the bridge notifies the engine room of end

of passage, record the following:

Time Main engine revolution counter Fuel oil counter

Fuel oil settling tank levels Diesel oil service tank level Fuel and diesel oil bunker tank levels Distilled and FW tanks levels

Manoeuvring

Trang 34

Stop both steering gear motors 2.12

The main turbine is now stopped and turning slowly with warming steam on line

Unless the turbine is to be shut down for repairs

or another specific reason, this is the condition the plant is normally left in while awaiting port operations

Ensure the boilers are firing on dual fuel if possible when in port, thus preventing gas being vented to the atmosphere

2.6.3

The Engine Room is now Ready

for Cargo Operations

The Vessel Is Manoeuvring

When all movements of the main turbine are completed, the bridge will transfer the control of the main turbines to the engine room and place the telegraph at FWE

Although the telegraph is indicating FWE, the turbine controls are still on automatic, and as such the turbine will turn on the auto-spin steam system

This system allows the main turbine to rotate ahead and astern at approximately 5 rpm, preventing the turbine from sitting in one position for a prolonged period of time which may cause the rotor to sag

Close the main turbine steam stop valve from the boilers and open the warming through line

3.4.2

Switch the auto-spin system off Put the main turbine to manual and from the ECR evacuate the main steam line pressure to approximately

4 bar, using the main turbine ahead and astern manoeuvres and then trip the turbine
