Academic and oral examination preparation for the MCA Certificate of Competency at Management Level — the gateway to Second Engineer and Chief Engineer rank under STCW Regulation III/2.
The 2nd Engineer / Chief Engineer CoC preparation pathway is a two-part programme that equips engineer officers to sit the Maritime and Coastguard Agency's (MCA) Certificate of Competency examinations at management level. It is not a single course but a structured sequence: first, a taught written-examination preparation programme covering the SQA Engineering Knowledge (Management Level) syllabus (General and Motor, or General and Steam papers), then a separate intensive oral examination preparation course before the face-to-face MCA oral — the final gateway to the CoC.
The qualification framework is governed by the MCA and underpinned by the STCW Convention (2010 Manila Amendments). The relevant regulations are STCW Regulation III/2 (vessels of 3,000 kW or more, Unlimited) and STCW Regulation III/3 (vessels of less than 3,000 kW). Written examinations are set and marked by the Scottish Qualifications Authority (SQA), which acts as the MCA's examining body; the MCA itself conducts the oral examinations. The governing UK Merchant Shipping Notice is MSN 1857 (M+F) Amendment 1. Under UK Merchant Shipping law, no person may serve as a Second or Chief Engineer on a qualifying UK vessel without the relevant CoC.
Written exam preparation typically runs over four to seven weeks depending on provider and whether attendance is in person, online, or blended. Oral preparation is commonly delivered as an intensive block of one to three weeks, or as rolling weekly sessions over a longer period. Before sitting the oral examination, candidates must obtain a Notice of Eligibility (NOE) from the MCA, confirming that sea service and ancillary certificate requirements are satisfied. The NOE is valid for five years. The SQA written examination pass is valid for three years; the oral examination pass is also valid for three years.
Achieving the Second Engineer CoC gives the officer full charge of the engine room in the absence of the Chief Engineer, with responsibility for machinery operation, maintenance planning, and the watchkeeping team. The Chief Engineer CoC is the pinnacle of the seafarer engineering hierarchy — senior officer responsible for all engineering operations aboard a vessel. Both ranks are in active demand across merchant navy, superyacht, offshore, and passenger vessel sectors. Shore-based roles that follow — particularly technical superintendent and fleet manager positions — are heavily weighted towards candidates holding or having held a Chief Engineer CoC.
The Certificate of Competency is valid for five years of seagoing service and must then be revalidated — not re-examined. Revalidation requires a minimum of twelve months' seagoing service performing functions appropriate to the certificate grade during the preceding five years, or completion of an approved refresher or updating course. Candidates must also hold a current ENG 1 medical certificate and have refreshed any ancillary safety certificates that have lapsed (STCW Basic Safety Training refreshers are required every five years; Advanced Fire Fighting, PSCRB, and others as applicable). There is no new oral examination for a straightforward revalidation. Applications are made electronically to the MCA; the same system handles renewal of expired certificates.
