A. As 2nd engineer, explain the procedure involved in complete inspection of a bottom end bearing;
B. List the precaution to be taken;
C. Indicate the reasons for possible defects which could be encountered and state how they may be rectified;
D. What test are carried out on completion of survey and re-assembly.
Q2. Describe how the following conditions are prevented in auxiliary boilers: A. Feed contamination by oil from heating coil drains; B. Internal corrosion; C. Furnace blowback; D. Uptake fire;?
Q3. Enumerate the maintenance routines carried out for the proper functioning of the following systems: A. Water hyper mist system B. Smoke detection system C. Quick closing valves D. Fire hydrants and hoses.
Q4. A. As a second engineer, how often would you check holding-down bolts to ascertain that they are tight? What methods are used to check tightness? B. If soon after joining a motor ship, you found a number of holding down bolts slack and fretting to have occurred in the area of slack bolts describe how you would handle the situation?
Q5. With respect to the operation of two stage reciprocating air compressor. Explain: A. The causes of occasional lifting of 2nd stage relief valve. B. Breakage of valve plates. C. Puncture of bursting disc of 1st stage intercooler. D. Noticeable reduction in capacity of the compressors over a period of time.
Q6. A. Describe the events leading to a crankcase explosion. B. State how overheating might be indicated other than by a mist detector. C. Discuss the procedure to follow in the invent of overheating being indicated. D. State how severity of a crankcase explosion is limited.
Q7. As a second engineer, list out all the potential hazards with regard to hot work on a fuel oil heater located inside a bunker oil fuel tank. Explain how do you carry out risk assessment for above mentioned hot work. What control measures do you employ so that residual risk shall be reduced as low as reasonably practicable (ALARP).
Q8. Severe engine vibration has recently become evident when the main engine for which you are responsible operates within a certain speed range – A. State, with reasons, the possible causes of such vibration; B. State the consequences of operating the engine under such vibratory conditions; C. Describe the procedure you, as Second Engineer, would implement in order to investigate and rectify the problem..
Q9. A. Briefly explain the term fatigue and explain how fatigue failure occur; B. State the difference between high stress / low cycle and low stress / high cycle fatigue giving an example of each; C. State how defect in metal can influence the expected safe life of a component; D. State how fuel injection timing and cylinder power balance can influence the possibility of fatigue cracks developing in the bedplate.
