1.17 Basic Marine Engineering at Support Level

Handling special tools

Special tools are used for the specific equipment or machinery on board. These tools should not be used for other purpose, should not modified in no case.

They are usually placed in separate boxes with clear address or special made board which accommodate each particular tool with the code number and address. After used these tools should be cleaned and fitted back exactly at the original place.

• (If deviate from normal value watch man should inform to duty engineer immediately.)

Inform to duty engineer and note the time on the notice board. When starting G/E, Check the condition and inform to duty engineer before and after synchronizing, Change sea chest from low to high (needs order from duty engineer), Drain air bottle and starting air line. Assist to duty engineer for stopping fresh water generator.

Waiting for an order what to do, note M/E.G/E,BOILER Flow meter, assist to duty engineer, Check main and auxiliary engine condition. During maneuvering time, check starting air line overheating, Check M/E jacket water temperature.

When the ship is already alongside OR anchorage, officer from bridge will inform Finish with engine (F.W.E), the duty engineer will give you an order what to do

• Closed starting air main valve,

• Open indicator cocks 

• Engage Turning gear

• Lubricate cylinder lubricator

• Start turning M/E by the turning gear 

• Check the turning gear motor ampere

Note: M/E, G/E, BOILER flow meter and G/E  K.W

• Check cascade tank level, Boiler water level

• Check Feed water pump suction and discharge pressure, 

• Check circulating water pump suction and discharge pressure when M/E starting

• Check F.O pump pressure or DO pump pressure.

• Check force draft fan operation when starting the boiler

• Check Steam pressure 

Necessary to understand oil fire boiler which is usually used in port and exhaust gas economizer which is used at sea.

Discuss about boiler soot blow.

1. Checking Emergency Equipment on board

• Check emergency generator diesel tank capacity, transferring fuel to the fuel tank without power, check battery voltage, after the generator is starting, check lube: oil pressure and temperature, exhaust temperature, jacket cooling water pressure and temperature, diesel oil pump pressure.

• Check Emergency compressor and air bottle pressure.

• Check Emergency fire pump, Checking pumps suction and discharge pressure during running

• Emergency Bilge suction and which is connecting with seawater pump suction.

• Check generator load on emergency switch board such as KW, Amp, and Hz

• If abnormal is found, inform to duty engineer.

• Check F.O, D.O storage, sett, service tanks, 

• Check L.O storage, sett, sump tank, for M/E, A/E

• Check freshwater storage tanks, and other tanks 

• Check Bilge holding tanks, bilge well condition

• Check Sludge tanks and drain tank 

• Check hydrophore tank level(automatics start ,stop set pressure)

• Check G/E RPM T/C RPM, Current &Voltage reading, Exhaust gas temp (all unit cylinder out let temp), Exhaust gas temperature before and after T/c , Jacket cooling water inlet pressure , temperature and out let temperature, Scavenge air pressure and temperature,

• Check lube oil sump level, Lube oil inlet pressure and temperature 

• Alternator bearings temperature 

• Check coolers, pumps 

• Watch man should know alarm set point and if abnormal is found, inform immediately to duty engineer.

• Check manual and auto running mode for compressors

• When starting check unloader valve opening and closing condition.

• Check 1st stage and 2nd stage pressure gauge

• Check outlet air temperature

• Check Lube oil pressure

• Watch man should know alarm set point and if abnormal is found, inform immediately to duty Engineer

• Check storage and service tank level and sludge tank level before starting.

• Check through put or feed rate

• Check back pressure 

• Check operating and sealing water tank level

• Check Ampere, Auto or manual desludging and time setting

•  Check sump oil level and abnormal sound,

•  Check Purifier room exhaust fan

• Check heating and temperature for storage tank

• Open valves from storage tank to settling tank

• Before starting, note the level of storage and settling tank

• Check pump suction and discharge pressure During starting

• After transfer operation is completed, close all valves

• Check operating water tank level

• Check F.O settling, service tank and L.O sump tank level, sludge tank level before starting 

• Check Separation temperature for F.O and L.O pressure

• Check F.O settling and service tank condition during running

• Check sump tank level for L.O during running

• Check feed rate or through put and back pressure (necessary to understand how to adjust)

• Check auto or manual desludging and time 

Checking running conditions of pumps, M/E lube: oil pump, M/E Cam shaft lube oil pumps, M/E F.O pumps (supply and Booster), M/E jacket pumps, Sea water pumps, Stern tube lube oil pumps and recording data. If abnormal is found, inform to duty engineer.

• Check which gravity tank is in-use (high or low tank), depend on ship draft

• Check gravity tank level, forward seal tank level, aft seal tank level, Drain tank level

• Check cooling system and check lube: oil flow in the sight glass

Check generator (same as above mention for generator) and inform to duty engineer about the generator for normal or abnormal running. So the duty engineer will synchronize the incoming generator.

Then check again for generator with load.

• High salinity alarm 

• Check salinity .If the salinity of the produced fresh water exceeds the permitted maximum value, alarm will activated and the solenoid valve is activated to dump automatically the produced fresh water to the bilge. The watch man should know preset salinity and if approaching to this or alarm, should inform to duty engineer.

• Check vacuum 

• Check shell temperature. 

• Check jacket water in and out temperature

• Check ejector pump suction and discharge pressure

• Check chemical tank level 

• Check distilled water pump discharge pressure.

• Check water leakage.

If abnormality is found, should inform immediately to duty engineer

Remote control manoeuvring system helps the ship engineers and deck officers to steer the ship safely from a control station (bridge or engine room), easing the process of monitoring and operation of marine engine power plant

What Does UHF and VHF Mean? UHF stands for “Ultra High Frequency” while VHF stands for “Very High Frequency.” UHF can range from low band (378-512 MHz) to high band (764-870 MHz) while VHF ranges from low band (49-108 MHz) to high band (169-216 MHz).
