Interview conducted for C/E&2/E candidate
1: What is the plant to ready for manoeuving and departure
port?
*start the second generator and after all checks, take it on load
*The third generator should be kept on standby condition *Essential steps to be noted: Turning engine indicator cocks parameters abnormal noise
*Check system FO service and settling tanks diesel oil service tank air system LO system T/C CW system checking the fuel regulating gear & starting system * slow turning the engine
*this must be carried out to prevent damage caused by fluid in one of the cylinders and to check the reversing mechanism
*Before beginning the slow turning obtain permission from the bridge
2 what items to be analysis on lube oil?
*Specific gravity viscosity flash point TAN(total acid
number)SAN(strong acid number) alkalinity TBN( total base number) water content Conradson carbon ash insoluble
3 what cause of exhaust temperature rises in all cylinders? * Increased scavenge air temperature owing to inadequate air cooler function
*Fouled air and gas passages
*Inadequate fuel oil cleaning or alerted combustion characteristics of fuel *wrong position of camshaft
4 what causes of high turbocharger speed?
*Fouled air filter(early stage of unloading the compressor) *Fire (early stage) in the exhaust check immediately. 5 what causes of cylinder knocking?
*Fuel timing too far advanced
*fuel injector valve needle sticking at open position *Excessive carbon built up on the crown *Broken exhaust valve
*Mechanical damage in the3 cylinder
6 what action to be taken of crankcase mist detector alarm (never cut out mist detector potentially dangerous)? *Inform bridge and C/E *Stay away from crankcases *slowdown and stop
*start turning gear immediately for at least 30 minutes to cool down
*Through investigation of mist detector crankcase abnormality and moving parts required
7 what caused of scavenge fire and action taken? *Inform bridge and C/E
*Do not stand near the relief valves
*slow down engine ensure that the auxiliary blowers are off *In case the fire persists stop the engine gradually to prevent risk of piston seizure
*Fire should be go off when all deposits burnt out
*keep turning the engine with cooling on to prevent seizure of moving parts
8 what action taken when crankcase explosion? (Most of the cases engine will suddenly stop upon explosion) *Inform bridge and chief engineer *evacuate the E/R
*Every safe effort to be made to turn engine by turning gear or slow turning for 30 minutes to prevent seizure of moving parts
*Thorough investigation required into the cause of the explosion before re starting
9 What will you do when boiler water level was low during normal steaming condition?
*Fist start the standby feed water pump
*Second check and wash the local water level gauge
*Third check any leakage on steam pipes or safety valves
10 Turbo charger surging causes and preventive measures? * T/C surging can be divided into three main categories * malfunction in the fuel system *Rapid variations in the engine load
* Fuel system fuel injection system fuel line components fuel timing
*exhaust system valve exhaust passage through turbocharger and gas boiler *scavenge air system
*Miscellaneous rapid changes in load and RPM governor *Immediate action temporarily counteracted by blowing off Reduce engine load by taking the T/C away from the surging line
*Preventive measures regular maintenance of items
mentioned above prevent load fluctuations during ballast voyage and bad weather
*Periodical check of M/E bedplate a strength member * Cross girder under the bearing housing *Bolt holes
* Holding down bolts of slackening *Chocks (fretting cracks and slackness)
11 Turbo blower maintenance during operation and check to be made during maintenance
Important points for turbo charger maintenance ? Gas casing scaling and corrosion ? Water treatment is essential
? Rotor unbalance due to improper cleaning of the air side as well as turbine side wheels
? Air side impeller usually have a film of oil on the aluminum surface
? Gas side in service cleaning necessary to prevent deposits from combustion products
? Improper cleaning of air side or turbine side could result in rotor unbalance and subsequent operational problems
? Bearings and gear pumps should be repaired at intervals specified by maker
12 Daily routine checks required on steering gear system. * Oil quantity in the oil tank within range of level gauge *Oil temperature
*Pressures of hydraulic cylinders comparing with normal data
* Abnormal noises and vibration from moving parts and motor couplings
* Oil leakages from tank cylinder valves ram packing and pipe joints
* Abnormal overheating of cylinder stuffing box and glands motor ampler
13 Immediate action/causes of abnormal related to steering gear system.
* Rudder does not respond * Trouble of auto pilot control
* Control the steering gear by the trick wheel in the steering gear room
* Failure in buffer spring levels and pins
* Continue the operation by changing to stand by pump unit after removing the broken part
* Trouble with hydraulic pump (including link mechanism)
* Check the link mechanism (coupling) and electrical power to the pump
* Lightly press the pump suction valve and check for oil suction
* Trouble or abnormal operation of valves * Obstacles around the tiller and ram
Rudder rate of turning speed low
? Slow auto pilot ordering
? Trouble and abnormal operation of valves ? External oil leakage
14 If main engine turbocharger out of operation due to rotor blade damage as a chief engineer what will be your plan and advise to all engineer to resume sea passage ASAP?
-If main engine one unit out of operation due to fuel pump roller guide damage (no spare part on board) what precaution will you take and your plan to resume passage with one unit cut off. -what do mean by balanced engine ( If peak pressure different ) what will be affect on engine
- If one unit peak pressure high compare to other unit what will be your action to balance the engine
- How you will adjust fuel pump timing for scroll type fuel pump?
- If timing advance or retarded what will be affect on engine exhaust temperature and peak pressure?
15 Pilot on board engine can not start from control room. As a chief engineer what will be your first action of plan.
- If can not start engine from engine local side what is your plan of action to start engine ASAP?
- What are you going to check in engine maneuvering system? - Before taking bunker what will your plan as a chief engineer? - How will you maintain main engine fuel system if AL/SL is high and also water content is higher side? Fuel and lube oil
purifier correct operation procedure and as a chief engineer advise to all engineer?
- Auxiliary engine running on heavy oil starting difficulties on DO what is your action to resolve starting problem?
-Boiler safety and action of plan if boiler tube leakage at sea. advise to all engineer regarding importance of boiler water treatment?
-Oily water separator operation and incinerator operation and how you going to fill up oil record book/sulpher record book? - oily water record book and incinerator capacity how will calculate in oil record book?
