GMA CoC EOOW study plan

GMA CoC EOOW · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Marine engineering watchkeeping and safe operation of machinery & Marine propulsion systems: diesel engines, steam and gas turbines

  • Explain the EOOW's duties for taking over, handing over and maintaining an engineering watch under way and in port, including the conditions that must be reported before a handover is accepted

  • List the machinery parameters (pressures, temperatures, levels, vibration, exhaust readings) an EOOW monitors each round and state the normal band and alarm/trip setpoint logic for each

  • Trace the sequence of a main diesel engine starting air, fuel and cooling water system from bridge command to propeller, identifying the interlocks and safety cut-outs at each stage

  • Describe the correct EOOW response to a blackout, a main engine trip and a steering gear failure, including immediate actions, notifications and watchkeeping records

Your checkpoint

A one-page watch handover checklist and a two-page machinery parameter log template with alarm/trip values filled in for the ship type you serve on

Week 2

Marine propulsion systems: diesel engines, steam and gas turbines

  • Compare two-stroke and four-stroke diesel engine scavenging, turbocharging and fuel injection so you can explain why a given fault causes the symptoms observed

  • Diagnose common propulsion faults (high exhaust temperature, scavenge fire, crankcase mist detector alarm, fuel valve sticking) from a set of given readings and state the first three actions for each

  • Explain steam turbine and gas turbine propulsion fundamentals: nozzle and blade action, gland sealing, rotor expansion, and why steam plant water chemistry matters

  • Calculate simple indicator diagrams, mean indicated pressure and specific fuel consumption from given data and interpret whether the result is acceptable

Your checkpoint

A fault-finding table of ten propulsion defects with symptom, probable cause, immediate action and prevention measure

Week 3

Auxiliary machinery and shipboard systems (pumps, compressors, boilers, steering gear, HVAC) & Electrical, electronic and control engineering; automation and instrumentation

  • Describe the operating principles, priming, cavitation, air-locking and discharge regulation of centrifugal, positive displacement and screw pumps, and select the right pump type for a stated duty

  • Explain boiler operation and safety: water level control, feedwater treatment, blowdown, and the low-water and flame-failure trip sequences

  • Outline steering gear types (ram, rotary vane, electro-hydraulic) and the SOLAS steering drill, emergency steering changeover and testing requirements

  • Explain how a PLC or alarm and monitoring system scans sensors, applies setpoints and drives alarms, trips and automatic start of standby machinery, including fail-safe and redundancy design

Your checkpoint

A systems diagram pack covering one pump circuit, the boiler feedwater and trip loop, and the steering gear hydraulic circuit, each annotated with the key alarms and limits

Week 4

Electrical, electronic and control engineering; automation and instrumentation & Maintenance and repair, materials and workshop practice

  • Read and interpret electrical single-line diagrams, motor starter circuits and protective relay settings, and explain discrimination between protective devices

  • Describe the maintenance of electrical equipment in hazardous areas, insulation testing, earthing and the precautions before working on live or isolated circuits

  • Plan a planned maintenance job from start to finish: isolation and lock-off, risk assessment, spares and tool selection, measurement and recording, and return to service

  • Explain workshop practice for shaft alignment, bearing fitting, clearances, torqueing and the use of measuring instruments such as micrometers, dial gauges and feeler gauges

Your checkpoint

A completed planned maintenance procedure for one real item of machinery, including isolation checklist, measurement record sheet and acceptance criteria

Week 5

Marine engineering watchkeeping and safe operation of machinery & Ship construction, stability and damage control for engineers

  • Describe the ship's watertight subdivision, the purpose of collision bulkheads, double bottoms and cofferdams, and how flooding spreads between compartments

  • Explain free surface effect, initial stability, centre of gravity and the effect of adding or removing weights on list, trim and metacentric height

  • Apply damage control procedure: locating and reporting damage, closing watertight doors, using portable pumps and shoring, and the engineer's role in the damage control party

  • Explain how hull stress, slamming and heavy weather affect machinery operation and what the EOOW must monitor and report

Your checkpoint

A worked damage control scenario write-up: given a flooding case, state the immediate actions, the stability considerations and the reports required

Week 6

Maritime legislation, STCW, MARPOL, SOLAS and survey/certification requirements

  • Map the STCW requirements for the EOOW certificate of competency: sea service, approved training, watchkeeping duties and the standards of competence to be demonstrated

  • State the survey and certification regime under SOLAS and class rules: annual, intermediate, renewal and statutory surveys, and the certificates a ship must carry

  • Explain MARPOL Annex I, IV, V and VI requirements that fall on the engineer: oil record book entries, oily water separator limits, garbage and sewage rules, and sulphur and NOx controls

  • Outline the ISM Code, the role of the designated person ashore, and how non-conformities and near-misses are reported and closed out

Your checkpoint

A one-page compliance summary sheet listing the certificates, logbooks and records an EOOW is responsible for checking, with the frequency of each

Week 7

Health, safety, environmental protection and emergency procedures & Engineering watch administration, records, communication and human element

  • Explain the emergency procedures for fire, abandon ship, man overboard, oil spill and enclosed space rescue, and the EOOW's specific duties in each muster list role

  • Describe the hazards of enclosed spaces, hot work, working aloft and electrical work, and how a permit-to-work and risk assessment control them

  • Explain the human element factors behind machinery casualties: fatigue, complacency, communication failure, authority gradient and the effect of rest hours

  • Draft clear, accurate engineering logbook entries, defect reports and verbal handovers, including how to escalate an unsafe condition through the chain of command

Your checkpoint

A set of three written records: a muster list duty card for your EOOW role, a permit-to-work for a hot work job, and a formal defect report for a machinery fault

Week 8

Marine engineering watchkeeping and safe operation of machinery & Marine propulsion systems: diesel engines, steam and gas turbines & Auxiliary machinery and shipboard systems (pumps, compressors, boilers, steering gear, HVAC) & Electrical, electronic and control engineering; automation and instrumentation

  • Answer timed mixed-domain practice questions across watchkeeping, propulsion, auxiliaries and automation, and score each attempt against the pass mark

  • Re-derive the weak areas from your practice scores and write a targeted revision list of no more than fifteen items

  • Rehearse oral examination answers to the classic EOOW scenarios: blackout, main engine trip, boiler low water, steering failure and fire in the engine room

  • Produce a final one-page formula and setpoint sheet you can revise from in the last days before the examination

Your checkpoint

Three timed mock papers completed with scores recorded and a final one-page revision sheet of formulas, setpoints and drill sequences
