Shaft Seals & Packing Keeping oil in and seawater out: oil control rings, wiper rings, gland packing, mechanical seals and labyrinth seals — with overhaul clearances. 1 Topic Heat Exchangers Shell-and-tube vs plate coolers: construction, cleaning, back-flushing and leak detection — plus what to do when temperatures creep up. 2 Topics Air Compressors & Receivers Starting-air supply end to end: reciprocating compressor overhaul, bumping clearance, safety devices and air-receiver rules. 2 Topics Pumps Every pump you will overhaul at sea: centrifugal, reciprocating, gear and screw pumps — dismantling, backlash, NPSH and cavitation cures. 3 Topics Steering Gear The gear that must never fail: steering-gear operation, oil charging and air purging — with the SOLAS tests surveyors always ask for. 1 Topic Refrigeration & AC Reefer plant from compressor to cold room: oil management, TEV operation, defrosting, servicing and the faults that warm up cargo. 2 Topics Purifiers & Centrifuges Clean oil, happy engine: purifier bowl parts, purifier vs clarifier, starting and stopping sequence, and the separation faults that dirty the oil. 3 Topics Pipelines & Valves The ship’s plumbing: bilge, ballast and bunkering lines, water hammer, globe/gate/butterfly valves and sea-chest care — failures included. 3 Topics OWS & STP 2 Topics Workshop & Practicals 1 Topic FWG & Hydrophore Fresh water at sea and pressure at the taps: fresh-water generator operation and hydrophore pressure-water systems with their faults. 2 Topics Main Engine Maintenance Open-up inspections that pass orals: scavenge and crankcase checks, crankshaft deflection, piston-liner-rings, plus crankcase explosions and scavenge fires. 4 Topics Aux Engine & Boilers Auxiliary engines and steam plant: valve timing, liner calibration, bearings, fuel pumps — plus water-tube vs fire-tube boilers and mountings. 2 Topics Watchkeeping Running the engine room like a professional: watchkeeping duties in port and at sea, work organisation and the safety rounds that prevent detentions. 1 Topic Viva Voce Examiner-style questions with model answers across machinery, engines and lube oil — revise here before the oral. 2 Topics
