Watchkeeping Flashcards
Describe the procedure for preparing a main engine, from cold, for sea service
PRE CHECKS
1), Start L.O Purifier - to clean and warm the oil.
2), Start ME L.O Pump - to pre-lubricate moving parts.
3), Start JW Circulating Pump - passes through pre-heater, the engine must be heated to 60°C for 6hrs.
4), Start F.O System - to warm up fuel.
5), Check L.O and F.O Tank Levels - drain water if present.
MAIN ENGINE
6), Open Indicator Cocks & Engage Turning Gear.
7), Turn Engine while manually operating Cylinder Lubricators (two-stroke)
8), Disengage Turning Gear.
AIR COMPRESSORS
9), Ensure Air Compressors are in Auto & Drain Air Bottles.
10), Open Air Start Valves and Auto Air Start Valves.
11), INFORM BRIDGE & Complete Telegraph Test.
BACK TO MAIN ENGINE
12), Blow Through Engine - to check for fluids.
13), Close Indicator Cocks.
14), Kick Engine Ahead & Astern - to confirm operation.
15), Inform Bridge that Engine is ready for Manoeuvring.
State the reason for turning the engine with the turning gear prior to starting
- Ensures the Engine Turns
- To Check there is no Build Up of Fluids in the Cylinders
- Assists in Spreading Lubrication through the Bearings
State the reason for leaving the lubricating oil circulating after “finish with engines”
- Assists with even cooling down of the engine
- Avoids any carbon build up from the oil
State why diesel alternator cooling water may be circulated through the main engine after shutdown
- Keeps engine warm, which prevents thermal shock if engine were needed to be started quickly.
- Reduces Condensate in the Cylinder
State why simultaneous injection of fuel oil and starting air into the main engine cylinder is undesirable
- Cause an Air Start System Explosion
Explain how simultaneous injection of fuel oil and starting air is prevented
- An air signal prevents this via an interlock.
- A “Stop Signal” to the stop air inlet on the fuel rack forces the governor to zero.
Explain how a leaking air start valve is detected while the engine is running
Air Start Branch Pipe will be Hot
- Blistering of Paint
- May Glow Red
Describe the actions to be taken upon discovery of a leaking air start valve
1), Reduce Load on the Engine.
2), Lift Fuel Pump on Affected Cylinder.
3), Stop as soon as possible.
4), Change/Repair the Leaking Valve.
5), DO NOT attempt to restart the engine until the branch pipe has completely cooled.
State EIGHT actions the EOOW would take on acknowledging unexpected high-level engine room bilge alarms, in both port and starboard bilge wells
1), Check bilge levels and assess the situation.
2), Start bilge pump
3), Source the cause of the rising bilge.
4), If possible isolate the cause
5), If not call for assistance and notify the Bridge.
6), If the normal bilge pump cannot control the level start an alternative pump.t
7), After starting check levels.
8), If still rising open the bilge injection valve, preferably with chief engineer’s permission.
The water level in the E/R is rising faster than can be contained by the bilge pump, Describe the Immediate action that the EOOW should take.
1), Call for assistance,
2), Close water tight doors,
3), Notify the bridge and C/E,
4),Start all pumps,
5), Identify the leak and stop it if possible,
6), As a last resort open the bilge injection valve preferably with the Chief engineers OK.
State the features provided in the engine room pumping system to deal with, The water level in the E/R is rising faster than can be contained by the bilge pump
BILGE INJECTION VALVE
- Last resort because you would be dumping oily water, (only done in the event of the vessels safety)
- Large Bore Suction to the Main S.W Pumps.
- Injection Valve is 2/3s the diameter of the sea chests diameter.
POSSIBLE DRAWING

AFTER ENGINE ROOM CHECKS
4), Switch Control to Duty Engineers Cabin.
5), Inform Bridge and Duty Officer of UMS mode Start.
6), On return, log findings and reset dead-man alarm.
7), Duty Officer should be aware of Duty Engineers location at all times.
In the case of a main engine and Controllable Pitch Propeller (CPP) not responding to bridge control, Describe the routine for changing to and using engine room control
1), Alert the Chief Engineer and engine room staff.
2), Stand by at the Engine Control Console (ECR)
3), Match CPP Pitch Settings, shown on the bridge with the current setting in the ECR.
4) Take Manual Control of CPP, switch from remote (bridge) to local (engine room).
5), Establish Continuous Communication with the Bridge .
6), Adjust pitch and engine speed manually as per bridge orders.
7), Monitor all parameters such as pitch indicators, shaft speed while also ensuring CPP system is functioning correctly.
8), Return to normal operation once the issue has been resolved.
Explain how control of fuel pump delivery is achieved when emergency manoeuvring on engine side control of a large 2 stroke crosshead engine
1), Alert Chief Engineer and engine staff and stand by in the ECR.
2), Match engine speed settings between bridge and ECR to avoid sudden changes.
3), Establish Communication with the Bridge.
4), Select manual control mode on the engine control panel.
CONTROL CAN NOW BE TAKEN OVER BY ENGINE SIDE
5), disconnect the governor to isolate automatic speed control.
6), Operate the manual control lever or wheel (on engine) to adjust the fuel rack and control engine speed.
7), Ensure control air valve is on local.
CONTROL IS NOW FULLY ON ENGINE SIDE
8), All operations are done manually based on bridge instructions.
State FOUR actions the EOOW would take on discovering a small oil fire in the engine room bilge
- Raise alarm.
- Isolate and restrict if possible.
- If small enough, tackle with portable fire fighting equipment.
- If too large, evacuate to muster points and send in fire party.
State FOUR good watch keeping practices that can help prevent small fires in the engine room bilge from occurring.
- Keep the bilges clean.
- Contain any oil leaks.
- Keep the bilges pumped.
- Regularly Check Bilges.
- Keep alarms tested and in good working order.
with reference to shutting down a main propulsion engine plant after voyage,
Explain the conditions to be met for transferring form Bridge Control to Engine Room Control just prior to shut down
1), Inform The Bridge - Confirm they are ready for the transfer of control.
2), Send the Engine Telegraph from the ECR to request transfer.
3), Press the Command Pushbutton - in the ECR to transfer control from bridge to engine room.
4), Observe the Indicator Lamps and Buzzer - the bridge lamp should extinguish while the ECR lamp should illuminate steadily.
5), Verify Control Transfer on the control panel and ensure engine telegraph responds correctly from ECR.
6), Once confirmed, proceed with engine shutdown procedures.
with reference to shutting down a main propulsion engine plant after voyage,
State FOUR precautions to be taken after shutdown, in order to ready the main engine for maintenance
- Shut Main Air Start Valves (isolate and lock)
- Engage Turning Gear
- Stop Main L.O Pumps - after allowing a cool down period.
- Open Indicator Cocks
- Crankcase Door should NOT be opened for 30mins after shutdown.
List EIGHT actions to be taken by the engineer officer of the watch to ensure the safe passage of the vessel through an area of heavy weather
1), Contact bridge and reduce load to an acceptable level to maintain steering but to prevent surging of the turbocharger as the propeller leaves the water.
2), Secure all stores to prevent movement;
3), Secure all tools/equipment to prevent movement;
4), Drain water from service tank/s;
5), Top up oil sump levels to prevent sensors from alarming

Describe EIGHT areas or items which should be checked by the duty engineer before taking over the watch
1), Running Generators - so that you are aware of what equipment is and should be running,
2), Load on generators – so during the watch you can check and account for any load changes,
3), Boiler water level – to ensure sufficient water is in the boiler and there is no discrepancies between gauge glasses,
4), Service tank level – to be aware of how much fuel there is and do any transfers need to be made,
5), Drain the settling and service tanks – to ensure no water build up is drawn into the engines,
6), Engine room logbook – to be aware of any work or transfers that have gone on during the previous watch,
