Croatia Chief Engineer Officer · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Marine Engineering Knowledge and Machinery Operation

  • Explain, from memory, the construction and operating cycle of two-stroke and four-stroke marine diesel engines, including scavenging, turbocharging and fuel injection timing

  • Sketch and describe the main components of a starting air system and a fuel oil service system, naming each valve, pump and safety device

  • Solve six numerical problems on indicated and brake power, specific fuel consumption, cylinder balance and mechanical efficiency

  • List the alarm and trip settings typically applied to main engine lubrication, cooling and overspeed protection, and justify each value

Your checkpoint

A hand-drawn one-page schematic of the main engine fuel, starting air and lubricating oil systems with all components labelled and a 10-line written explanation of the operating sequence

Week 2

Marine Engineering Knowledge and Machinery Operation & Marine Propulsion Systems and Auxiliary Machinery

  • Diagnose five given main engine fault scenarios (scavenge fire, exhaust valve burning, liner scuffing, fuel pump timing error, crankcase mist) and state the symptoms, immediate actions and root causes

  • Compare the construction and operating limits of fixed-pitch and controllable-pitch propellers, and describe shafting, stern tube bearings and the steering gear types fitted to merchant ships

  • Explain the operation of boilers, fresh water generators, purifiers and air compressors as auxiliary machinery, including their safety interlocks

  • Calculate propeller slip, shaft power and fuel consumption for a stated voyage, and interpret the result against the engine load diagram

Your checkpoint

A fault-finding table covering at least eight main engine and auxiliary machinery faults with columns for symptom, probable cause, immediate action and preventive measure

Week 3

Marine Propulsion Systems and Auxiliary Machinery & Ship Construction, Stability and Damage Control

  • Describe the layout and purpose of bilge, ballast, fuel transfer and cargo piping systems, and state the pollution-prevention features of each

  • Explain intact and damage stability using the terms KG, GM, GZ, free surface effect and angle of loll, and assess how a given loading condition changes each

  • Describe hull construction features: double bottom, transverse and longitudinal framing, bulkheads, watertight doors and collision bulkhead requirements

  • Explain damage control procedures including flooding boundary setting, cross-flooding, list correction and the use of the damage control plan

Your checkpoint

A worked stability problem showing the effect of adding ballast and consuming fuel on GM and list, with a written damage control action plan for a simulated side-shell breach

Week 4

Maritime Law, STCW and Flag State Regulations & Safety of Life at Sea, Fire Prevention and Firefighting

  • State the chief engineer's statutory responsibilities under SOLAS, MARPOL, STCW and the ISM Code, and identify which records and certificates the chief engineer signs or maintains

  • Explain the STCW watchkeeping and rest hour requirements, the engine room watch arrangement and the procedure for handing over a watch

  • Describe the classification of fire, the fire triangle, and the fixed firefighting systems found in machinery spaces including CO2, foam and water mist, with their activation and release precautions

  • Outline the muster list duties, fire patrol, fire control plan and the actions of the engine room team during an abandon ship or machinery space fire

Your checkpoint

A one-page checklist of certificates, records and drills the chief engineer is responsible for, cross-referenced to the relevant convention or code

Week 5

Marine Pollution Prevention and Environmental Protection & Electrical, Electronic and Control Engineering

  • Apply MARPOL Annexes I, IV, V and VI to engine room operations, stating the discharge limits, record book entries and equipment requirements for oily water, sewage, garbage and exhaust emissions

  • Explain the operation of the oily water separator, sewage treatment plant and incinerator, and the alarms and monitoring that prevent illegal discharge

  • Describe the main and emergency switchboard arrangements, preferential tripping, earth fault detection and the procedure for isolating a circuit for maintenance

  • Explain the operation of alternators, transformers, motor starters and variable frequency drives, and interpret a simple electrical schematic

Your checkpoint

A compliance summary sheet listing each relevant MARPOL annex with its discharge limit, required record book and the chief engineer's verification duty, plus a labelled sketch of the emergency switchboard supply path

Week 6

Electrical, Electronic and Control Engineering & Maintenance and Repair, Materials and Workshop Practice

  • Diagnose five electrical fault scenarios including earth fault, single phasing, alternator failure to excite and blackout, and state the immediate and follow-up actions

  • Explain planned maintenance systems, condition monitoring, vibration analysis and the classification of maintenance tasks by interval and criticality

  • Describe materials and workshop practice: steel grades and their weldability, bearing materials, corrosion control, and the correct use of measuring instruments and torque procedures

  • Explain the procedure for obtaining class and flag state approval for a temporary repair, and the records required

Your checkpoint

A planned maintenance schedule for one auxiliary system covering at least ten items, each with interval, task, acceptance criteria and record kept

Week 7

Ship Management, Leadership and Human Element & Medical Care and First Aid On Board

  • Describe the chief engineer's role in the safety management system, including risk assessment, permit to work, toolbox talks and incident investigation

  • Explain the human element factors behind engine room accidents: fatigue, communication failure, complacency and authority gradient, and the countermeasures available

  • Apply the principles of medical first aid to burns, fractures, hypothermia, drowning and chemical exposure in the machinery space, including the use of the medical guide and radio medical advice

  • Outline the contents and use of the ship's medicine chest and the procedure for requesting radio medical advice

Your checkpoint

A written case study of one engine room accident covering causal factors, the leadership and SMS failures involved, and the corrective actions a chief engineer would implement
