STCW MCA Management Level Career Advancement

Second Engineer Officer CoC

The management-level Certificate of Competency required by law to serve as Second Engineer on seagoing merchant vessels — issued under STCW Regulation III/2 (unlimited) or III/3.

Study: 5–20 weeks taught Sea Service: 12 months post-EOOW Issuing Body: MCA / Irish Maritime Administration Validity: Revalidation every 5 years

Course Overview

The Second Engineer Officer (2/E) Certificate of Competency is a management-level qualification issued under the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW). In the United Kingdom it is administered by the Maritime and Coastguard Agency (MCA); in Ireland by the Irish Maritime Administration via the Department of Transport. The certificate is legally required for any engineer officer serving in the role of Second Engineer on a seagoing merchant vessel, and is recognised in ports worldwide as STCW is an IMO Convention ratified by the vast majority of flag states.

The regulatory framework sits under STCW Regulation III/2 for vessels of 3,000 kW propulsion or more (the unlimited certificate), or STCW Regulation III/3 for vessels of 750 kW to 3,000 kW. The competency standards are defined in STCW Code Tables A-III/2 and A-III/3 respectively. In the UK these are implemented via the Merchant Shipping (Standards of Training, Certification and Watchkeeping) Regulations 2015 (SI 2015/782), with detailed requirements published in MCA Merchant Shipping Notice MSN 1857 (M+F).

The 2/E CoC is not a single taught course but a combination of approved education and training, SQA management-level written examinations, an MCA oral examination, and qualifying sea service. The taught element typically runs from five weeks (Fleetwood Nautical Campus) up to one semester at NMCI Cork, preparing candidates for Engineering Knowledge General and Engineering Knowledge Motor (and/or Steam) written papers. The Second Engineer is the senior officer in the engine department reporting directly to the Chief Engineer, with responsibility for daily machinery operations, maintenance supervision, watchkeeping oversight, and acting as Chief Engineer when required.

Prerequisites

  • Valid Engineer Officer of the Watch (EOOW) CoC (STCW III/1)
  • At least 12 months approved seagoing service as assistant engineer or officer in charge of an engineering watch on vessels of at least 750 kW (at least 9 months in full watch charge for the unlimited III/2 route)
  • Valid ENG1 medical fitness certificate
  • Completion of an MCA-approved education and training programme meeting STCW A-III/2 competency standards
  • Applicable ancillary STCW safety certificates (Basic Safety Training, Advanced Fire Fighting, Medical First Aid, GMDSS as applicable)
  • Application submitted to MCA on form MSF 4275

What You Will Be Qualified To Do

  • Serve as Second Engineer Officer on seagoing merchant vessels of 3,000 kW or more (unlimited route) or 750–3,000 kW (limited route)
  • Supervise all machinery operations and engineering department maintenance programmes
  • Oversee officer engineering watchkeeping in compliance with STCW requirements
  • Act as Chief Engineer Officer when required
  • Manage fuel, lubricants, and consumables for the engineering department
  • Take responsibility for the safety and operational readiness of all main and auxiliary machinery

Career Progression

BEFORE
Engineer Officer of the Watch (EOOW) CoC — STCW III/1
The essential prerequisite. Typically gained after a marine engineering cadetship of three to four years including sea time and college phases. Certifies the holder to stand an unsupervised engineering watch on vessels of any propulsion power.
THIS COURSE
Second Engineer Officer CoC — STCW III/2 or III/3
Management-level certificate. Requires 12 months qualifying sea service post-EOOW, completion of an approved training programme, and passes in SQA management-level written examinations plus an MCA oral examination. The full process typically takes 1.5–2 years from EOOW level.
NEXT STEP
Chief Engineer Officer CoC — STCW III/2 (Chief)
A further 12 months approved seagoing service after gaining the 2/E CoC is required before sitting Chief Engineer written and oral examinations. Chief Engineer is the most senior engineering position on any vessel.

Holding a Second Engineer Officer CoC opens roles as 2/E on deep-sea cargo ships, tankers, container vessels, ferries, offshore support vessels, and large commercial yachts above the applicable power threshold. It also qualifies holders for shore-based technical superintendent roles, marine surveying pathways, and positions with flag state administrations. The full merchant navy engineering career ladder runs: Rating or Cadet → EOOW (III/1) → Second Engineer (III/2 or III/3) → Chief Engineer (III/2) → Superintendent or shore technical roles.
