Q1. A. Outline the procedure for the inspection of the rudder in a dry dock,
B. What are the requirements with respect to steering gear as per SOLAS 74, as amended for the following:
i. Relief valve;
ii. Steering gear control;
iii. Electrical power circuit
Q2. A. Describe the procedure for opening a bottom end bearing for inspection making reference to the positioning of the crank and the safety precautions to be observed.
B. State how the bearing clearance may be checked and adjusted when necessary.
C. State TWO defects, which may be encountered during inspection of the bottom end bearing and crankpin giving possible causes of EACH.
D. State TWO checks, which should be made before returning the engine to service following an overhaul of the bottom end bearing.
Q3. A). Describe the overhaul of a boiler safety valve and explain using sketches where necessary those parts which require particularly close attention;
B). Describe the setting of the boiler safety valve to comply with classification society requirements.
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. A. During the weighment of CO2 bottles required for total flooding of the Engine room, it was observed that few bottles are less than the original capacity. State the reasons for the same and checks/tests to be made prior to refilling;
B. State how often the CO2 bottles are required to be weighed and pressure tested.
Q6. With the aid of a simple sketch, explain the “trouble spots” in a basic air-conditioning unit with reference to your sketch, explain the following:-
i. How the problem of the increase in humidity of cooled air is overcome?
ii. How discomfort caused by the excessive drying effect of heated air is overcome?
Q7. Sketch FIVE methods used to prevent the distortion of ship’s plates and frames during major welded hull repairs in dry dock.
Q8. 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 a 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).
Q9. With regard to a large 2 stroke engine: (a) Explain how can the cooling spaces within a cylinder jacket be examined without withdrawing the cylinder liner? (b) To what parts of a cylinder jacket would give attention after removing an old cylinder liner prior to fitting a new one? (c) What periodic attention must be given to the scavenge air space and piston-rod packing (Stuffing box) at the bottom of a
