MAJ EOOW Engineer Exam study plan

MAJ EOOW Engineer Exam · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Marine Engineering Knowledge - Propulsion Plant and Machinery Operation

  • Draw from memory a labelled line diagram of a two-stroke slow-speed propulsion plant covering main engine, scavenge air, exhaust gas economiser, fuel and lube oil circuits, and explain to yourself the energy flow at full load.

  • Explain the sequence of events inside the cylinder of a two-stroke engine from scavenge port opening to exhaust valve closing, and state the purpose of each phase.

  • Describe how a propeller law load diagram is used to check whether the engine is overloaded at a given shaft speed, and work through one numerical example.

  • List the main engine protection trips and interlocks and state the condition each one protects against.

Your checkpoint

A one-page hand-drawn propulsion plant schematic with a 300-word written explanation of energy flow and overload diagnosis, self-marked against your reference notes.

Week 2

Marine Engineering Knowledge - Propulsion Plant and Machinery Operation & Engine Room Watchkeeping, Procedures and Record Keeping

  • Explain how starting air, fuel index, governor action and turning gear interlocks combine to make a safe main engine manoeuvring sequence from bridge order to propeller response.

  • Describe the checks and actions for preparing main and auxiliary machinery for sea, including warming through, standby pumps and steering gear testing.

  • Write out the standard engine room watch handover items and justify why each one matters for the incoming watchkeeper.

  • Interpret a set of running readings (exhaust temperatures, scavenge pressure, fuel index, turbocharger speed) and state what deviation would prompt investigation.

Your checkpoint

A completed watch handover checklist template plus a 250-word worked diagnosis of one abnormal running condition from given readings.

Week 3

Auxiliary Machinery and Systems (pumps, compressors, boilers, steering gear, deck machinery)

  • Explain the operating principle, starting method and capacity control of the main air compressors and state the safety devices fitted to the air receivers and their settings.

  • Describe the feed water and condensate system of an auxiliary boiler, including feed pump control, water level alarms and low-water trip testing.

  • Explain how a two-ram electro-hydraulic steering gear follows the helm order, and list the checks required before departure under SOLAS steering gear requirements.

  • Describe the hydraulic and mechanical safety arrangements on deck machinery such as windlass and mooring winches, including brake holding tests.

Your checkpoint

A tabulated list of pre-departure tests for steering gear, air receivers and boiler safety devices with the acceptance criteria for each.

Week 4

Maintenance and Repair of Shipboard Machinery and Systems

  • Produce a planned maintenance schedule for one auxiliary system covering weekly, monthly and annual tasks with the reason for each interval.

  • Explain how to take and interpret a crankcase oil sample and what wear-metal trends indicate about bearing condition.

  • Describe the procedure for safely isolating, locking off and proving dead a pump or motor before maintenance, and the permit-to-work records required.

  • Explain how to measure and assess cylinder liner wear and piston ring condition, and when renewal is due.

Your checkpoint

A one-page planned maintenance schedule for a chosen auxiliary system with isolation steps and record entries, reviewed against the ship's planned maintenance system format.

Week 5

Electrical, Electronic and Control Engineering & Ship Construction, Stability and Damage Control as Applied to Machinery Spaces

  • Explain the operation of a three-phase alternator, synchronising procedure and load sharing between generators, including what happens on loss of one generator.

  • Trace a motor starter circuit from the distribution board through contactor, overload and remote control, and explain the protection each element provides.

  • Describe the arrangements that keep the engine room watertight and fire-resisting, including bulkhead penetrations, dampers, skylights and escape routes.

  • Explain how flooding or a large free surface in a machinery space affects stability and list the immediate actions to control it.

Your checkpoint

A labelled sketch of a generator synchronising and load-sharing arrangement with a 200-word explanation of blackout recovery actions.

Week 6

Shipboard Safety, Pollution Prevention and Emergency Response (including MARPOL and SOLAS)

  • State the MARPOL Annex I machinery space discharge restrictions and the oil record book entries required for bilge transfers, sludge disposal and oily water separator operation.

  • Describe the fixed firefighting arrangements in a machinery space, the fuel quick-closing valve test and the actions on detecting an engine room fire.

  • Explain the SOLAS drills and musters expected of engine room personnel and the role of the emergency generator and emergency fire pump.

  • Describe the response to a major fuel oil or lube oil leak into the bilge and the pollution reporting chain.

Your checkpoint

A completed sample oil record book page for five realistic operations plus a 250-word engine room fire response sequence.

Week 7

Maritime Law, STCW and Flag State Regulations & Engine Room Watchkeeping, Procedures and Record Keeping

  • State the STCW watchkeeping principles, rest hour requirements and fitness-for-duty obligations that apply to an engineer officer of the watch.

  • Explain the survey and certification regime that keeps a ship trading, including the role of classification society and flag state in machinery surveys.

  • Describe the reporting and recording duties after a machinery casualty, near miss or pollution incident, and the purpose of each record.

  • Explain how port state control inspections of the machinery space are prepared for and what documentary evidence inspectors commonly request.

Your checkpoint

A one-page summary table linking five key certificates and records to the regulation behind them and the person responsible for keeping each current.

Week 8

Human Element, Leadership and Team Management in the Engine Room & Marine Engineering Knowledge - Propulsion Plant and Machinery Operation & Shipboard Safety, Pollution Prevention and Emergency Response (including MARPOL and SOLAS)

  • Explain how to brief and supervise a mixed-experience watch team during an unfamiliar or high-workload task, including closed-loop communication.

  • Describe how fatigue, complacency and authority gradient contribute to engine room incidents and the countermeasures a watchkeeper can apply.

  • Work through two integrated scenarios combining propulsion plant failure, emergency power and pollution response, stating decisions in sequence.

  • Complete a timed self-test across all domains and identify the three weakest areas for further revision.

Your checkpoint

A written debrief of two integrated scenarios covering decisions, communications and records, plus a ranked list of three revision priorities.
