Q1. Explain in detail how you would isolate one of the sprinkler systems for routine maintenance. Describe all tests and inspections you would make and how you would return the system to service.
Q2. With reference to reciprocating air compressors explains the cause of the following faults. A. Collapse of discharge valve springs; B. Breakage of plate valves; C. Overheating of the discharge air with an unrestricted air intake; D. Inoperative piston rings.
Q3. With reference to main engine automatic slowdown and shutdown systems; A. List TWO parameters for shutdown and slowdown, state reasons for having these parameters for shutdown and slowdown of engines. B. How are the above-chosen parameters tested while the engine is in operation?
Q4. 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 increase in humidity on cooled air is overcome? ii. How discomfort caused by the excessive drying effect of heated air is overcome?
Q5. Describe the procedure to remove a seized fuel injector body from the cylinder head when it could not be removed by conventional means. Also, list out preventive measures that could be implemented in the vessel so that such a seizure can be prevented in the future.
Q6. Describe the procedure for overhauling Main Air compressor Valves (Plate type) and explain which parts require close attention. using sketches where necessary. Also, describe the procedure for testing these compressor valves.
Q7. With reference to Auxiliary boiler safety valve; A. Describe with the aid of Sketch the safety valve for an auxiliary boiler; A. Identify with reasons. The parts that require particularly close attention during overhaul; B. Describe how the safety valves are reset after an overhaul.
Q8. 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.
Q9. During the past 4 months since you joined the ship as 2nd engineer a number of main engines exhaust valves have suffered from cracking and corrosion at the seating faces; Write a report to the superintendent engineer covering the following points; A. An explanation detailing how the problem becomes evident; B. Your action upon recognizing the extent and seriousness of the problem; C. Your reasoned view regarding the possible cause of the problem; D. Your recommendation to avoid future incidents.
