A structured online study programme preparing engine department seafarers for the MCA IAMI written examinations and oral assessment leading to the Engineer Officer of the Watch Certificate of Competency.
The EOOW Exam Preparation (online) course is a flexible e-learning programme designed to help engine department seafarers pass the formal examinations required for the Engineer Officer of the Watch (EOOW) Certificate of Competency (CoC) under STCW Regulation III/1. The course does not itself award a certificate; instead it builds the knowledge and exam technique required to pass the IAMI Engineering Knowledge (EK) written papers and the subsequent MCA oral examination. Delivered online with live tutor support, it is structured to fit around sea service commitments without requiring study leave.
The MCA EK examination syllabus covers five principal areas: auxiliary equipment (watchkeeping duties, ballast and bilge systems, sewage, refrigeration, fire safety, pollution prevention, and enclosed space entry); ship construction and electrical (generators, parallel operation, storage batteries, circuit diagrams, structural knowledge, and load line surveys); motor section (two-stroke and four-stroke diesel engines, turbochargers, starting and stopping procedures, emergency procedures, scavenge fires, crankcase oil mist detection, and economiser fires); steam section (boilers and turbines, condensate systems, gearing, boiler water testing and contamination); and control engineering (transducers, pneumatic and electrical actuators, on-off and continuous control systems, and BS 1553/BS 1646 diagrams).
The full qualification — the EOOW CoC — is an international requirement under the STCW Convention 1978 as amended by the 2010 Manila Amendments. In the UK it is administered by the Maritime and Coastguard Agency (MCA) and is required for anyone serving legally as a watchkeeping engineer officer on any seagoing vessel of 750 kW or above. The UK CoC is recognised worldwide under the STCW Convention White List.
The EOOW CoC is the entry-level officer-grade engineering qualification and the gateway to a full MCA engineering officer career. It legally authorises the holder to serve as Officer in Charge of an Engine Watch (OICEW) on any seagoing merchant ship of 750 kW and above, including superyachts above the relevant tonnage and power thresholds. From EOOW the recognised progression runs to Second Engineer (STCW III/3) and ultimately Chief Engineer (STCW III/2), the management-level qualification that heads the entire engine department. The full engineer career ladder is: Engine Watch Rating / MEOL → EOOW (III/1) → Second Engineer (III/3) → Chief Engineer (III/2).
Prerequisites summary: Candidates must hold an Engine Watch Rating Certificate (STCW III/4), MEOL, or Senior MEOL, plus the required approved sea service totalling 33 months in the engine department (including 9 months on ships of at least 750 kW), a completed MNTB Training Record Book, four basic STCW safety certificates, and a valid ENG1 medical fitness certificate.
Revalidation: The EOOW CoC is valid for 5 years. Revalidation requires at least 12 months approved seagoing service as an engineer officer on any seagoing ship of at least 350 kW within the preceding 5 years (or approved sea service combined with approved updating training), completion of MCA-approved Advanced Fire Fighting refresher training (STCW Table A-VI/3) within the preceding 5 years, a valid ENG1 medical certificate, and submission of MCA form MSF 4201. Revalidation is an administrative process; the written and oral examinations do not need to be re-sat unless the CoC has lapsed entirely.
