ExploreAbout this exam
The NIMASA STCW Maritime Safety Administration Examination is the assessment route through which Nigeria's maritime administration verifies that seafarers and shore-side maritime personnel meet the standards of the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers. Candidates typically include deck officers and ratings, engineer officers and engine-room ratings, and personnel seeking Nigerian certificates of competency or proficiency, endorsements, or revalidation. The examination is delivered in English and blends multiple-choice papers with written or descriptive answers, so you must be able to both recognise the correct option and explain a procedure or regulation in your own words. Content follows the STCW chapters: navigation and watchkeeping, engine-room watchkeeping, safety and emergency procedures, maritime law and convention compliance, ship construction, stability and cargo work, MARPOL and pollution prevention, the ISPS Code, GMDSS communications, and the human element, first aid and survival. Preparation should be built around the STCW Code tables of competence for your grade, the underlying conventions themselves (SOLAS, MARPOL, COLREGs, STCW, ISPS, MLC where relevant) and NIMASA circulars. Work through written answers under time pressure, drill collision regulations and pollution record-keeping, and confirm current administrative requirements directly with NIMASA, which publishes the applicable fees, schedules and pass criteria.
What you'll study
About NIMASA STCW MSA preparation
Who actually needs to sit this examination?
Mainly candidates applying for Nigerian STCW certificates of competency or proficiency, endorsements and revalidations, plus ratings and shore personnel whose duties require demonstrated competence. The exact certificate grade you apply for determines which papers you sit, so confirm your eligibility and required modules with NIMASA before booking.
What is the format of the papers?
Expect a mix of multiple-choice questions and a written or descriptive paper, delivered in English. Written sections ask you to describe procedures, explain regulatory requirements or justify a decision, so practise producing clear structured answers rather than bullet fragments. Confirm the current paper structure for your grade with NIMASA.
How long is the exam and what does it cost?
NIMASA publishes the current examination schedule, fees and sitting arrangements, and these change over time, so no figure is quoted here. Check the NIMASA website or your approved training provider for the authoritative details before you plan travel, leave or payment.
What score do I need to pass?
The passing criteria are set and published by NIMASA, so obtain the current requirement from the agency or your training provider rather than relying on hearsay from other candidates. Assessment rules can differ between certificate grades and between multiple-choice and written components.
How difficult is it, honestly?
Candidates with genuine sea time usually find the practical and watchkeeping material familiar but underestimate the regulatory and written components. The common difficulty is precision: exact distress procedures, correct MARPOL record entries, accurate COLREGs application. Memorising question patterns without understanding the convention behind them tends to fail on descriptive answers.
Can I retake a failed paper, and how soon?
Retake rules, waiting periods and any limits on attempts are administrative matters set by NIMASA. Ask the agency directly when you register, and keep your result slips and application records. Do not assume another candidate's retake experience applies to your grade or centre.
In what order should I study the domains?
Start with the conventions that underpin everything else: STCW itself, COLREGs, SOLAS and MARPOL. Then layer on your grade-specific competence tables, watchkeeping scenarios and emergency procedures. Finish with GMDSS, ISPS and first aid, which are narrower but easy marks if revised close to the exam.
What are the most common failure modes?
Weak written expression, confusion between similar convention requirements, poor recall of pollution and safety record-keeping, and misapplying collision regulations to crossing or overtaking scenarios. Candidates also lose marks by answering what they do on their own ship rather than what the convention requires.
Where can I find the official requirements?
The Nigerian Maritime Administration and Safety Agency publishes examination guidance, schedules and administrative requirements on its official website and through its offices. Always treat NIMASA as the authoritative source for eligibility, fees, dates and results rather than third-party summaries.
