OOW (Engine) Orals Preparation

Intensive tutor-led coaching for the MCA oral examination — the mandatory final gateway to a UK STCW III/1 Engineer Officer of the Watch Certificate of Competency.

Duration: 2–4 weeks Issuing body: MCA CoC valid: 5 years

Course Overview

The OOW (Engine) Orals Preparation course — formally known as EOOW (Engineer Officer of the Watch) Orals Preparation — is an intensive, tutor-led programme that prepares marine engineering cadets and junior officers for the Maritime and Coastguard Agency (MCA) oral examination. That oral exam is the compulsory final assessment for obtaining a UK Certificate of Competency (CoC) as an Engineer Officer of the Watch. The course itself awards no certificate; it is expert coaching that equips candidates to demonstrate the full range of competencies an MCA examiner will test.

The qualification framework is governed by STCW Regulation III/1 — the international standard for Officers in Charge of an Engineering Watch on ships with main propulsion machinery of 750 kW or more. The oral examination syllabus is defined in MCA Marine Guidance Notice MGN 69 (M), with the most recent update published as Marine Information Note MIN 654 Amendment 1 (November 2024). The MCA is the sole authority for issuing UK STCW engineering CoCs; the preparation course is delivered by approved maritime training colleges, not by the RYA, which covers leisure and yacht deck qualifications rather than merchant engineering.

Providers typically offer the course over two to four weeks. A four-week delivery (such as Fleetwood Nautical Campus) works through the complete oral syllabus from scratch and suits candidates who want fully structured preparation. A two-week intensive (such as Glasgow Maritime Academy) assumes prior independent study and focuses on focused revision and mock oral practice under examination conditions.

Prerequisites
  • MCA Notice of Eligibility (NoE) — applied for directly with the MCA
  • Minimum age 18; valid ENG1 medical fitness certificate
  • Pass certificates for IAMI EOOW written Engineering Knowledge examinations (General, Motor and/or Steam, and Control Engineering) — all within 3 years prior to CoC application
  • Approved seagoing service: MNTB training route requires at least 6 months watchkeeping on ships ≥750 kW; experienced seafarer route requires at least 30 months seagoing service
  • Completed MNTB Training Record Book (TRB)
  • Mandatory STCW ancillary safety certificates: Basic Safety Training (STCW A-VI/1), Advanced Fire Fighting, Medical First Aid or Medical Care, and Security Awareness
What the Course Covers
  • Full MCA EOOW oral examination syllabus as defined in MGN 69 (M) and MIN 654 Amendment 1 (November 2024)
  • Main propulsion machinery operation — motor and/or steam endorsements
  • Control engineering and automation systems
  • Engine room watchkeeping and Unmanned Machinery Space (UMS) procedures
  • Emergency procedures: damage control, fire response, flooding, and pollution prevention (MARPOL obligations)
  • Auxiliary systems: boilers, steering gear, bilge and ballast, fire detection and suppression
  • Mock oral examinations under examiner-style conditions

Career Progression

BEFORE
IAMI EOOW Written Exams & Approved Sea Service
Complete the IAMI engineering knowledge written examinations (General, Motor and/or Steam, Control Engineering) and accumulate the required approved seagoing service — via the MNTB officer training programme or the experienced seafarer route — to obtain an MCA Notice of Eligibility.
THIS COURSE
OOW (Engine) Orals Preparation
Tutor-led coaching across the full MCA EOOW oral syllabus, with mock oral practice. On passing the subsequent MCA oral examination and completing a successful CoC application, candidates are awarded the EOOW Unlimited (STCW III/1) Certificate of Competency — entry-level officer status in the engine department.
NEXT STEP
Second Engineer & Chief Engineer (STCW III/2)
With 12 months approved sea service as EOOW or assistant engineer (including at least 9 months in full charge of watch or UMS duties on ships ≥750 kW), officers may progress to the Second Engineer CoC (Class 2). Further sea service opens the route to Chief Engineer (Class 1).

The EOOW III/1 CoC is the foundation of the entire UK merchant navy engineering officer career ladder — every route to Second Engineer and Chief Engineer passes through it. The CoC entitles the holder to serve as Engineer Officer of the Watch on any motor or steam ship (depending on endorsements held) with propulsion machinery of 750 kW or more, in international waters, without tonnage restriction. Roles open to EOOW certificate holders include junior engineer officer, fourth or third engineer, and watchkeeping engineer across deep-sea and short-sea vessel types.

Cost note: Fleetwood Nautical Campus charges £775 for its 4-week programme (course materials included). Glasgow Maritime Academy charges £1,675 for its 2-week intensive. The MCA oral examination fee is charged separately by the MCA and is not included in any course fee. Always confirm current pricing directly with the provider.

CoC Revalidation

The EOOW CoC must be revalidated every five years. Revalidation requires a valid ENG1 medical certificate, evidence of recent sea service (360 days in the preceding five years allows a shorter administrative revalidation; less than this requires a refresher course with practical reassessment), and current STCW safety certificates — Personal Survival Techniques, Fire Prevention and Fire Fighting, and Advanced Fire Fighting must all be within their five-year validity or refreshed. Applications are submitted to the MCA via form MSF 4201. The orals preparation course itself does not expire and does not require renewal; only the resulting CoC and the underlying STCW safety certificates need periodic revalidation.
