ExploreAbout this exam
SOLAS Instrumentation is a specialist assessment for people who specify, commission, survey, maintain, or inspect the instrumentation and alarm systems that the International Convention for the Safety of Life at Sea (SOLAS) requires on board ship. It suits marine engineers, electro-technical officers, classification-society and flag-state surveyors, systems integrators, and technical superintendents who need to connect a regulatory clause to the actual sensor, detector, alarm, or control loop on board. The examination is not a general seamanship test. It asks you to move between the convention text and the hardware: which chapter imposes the carriage requirement, what performance standard applies, how the system must behave under fault, and what evidence a surveyor will accept. Expect multiple-choice items that test precise clause knowledge and scenario reasoning, plus written or essay questions that are site-specific - you may be asked to justify a design, describe a survey or test procedure, or analyse a failure. Preparation works best in layers: first build a solid map of the SOLAS chapters and amendment cycle, then study each equipment domain against its performance standards and survey requirements, then practise writing short, clause-referenced answers. Confirm current administrative details with the official awarding body, as they publish the authoritative figures.
What you'll study
About SOLAS Instrumentation preparation
Is this an official SOLAS or IMO certification?
No. IMO does not administer a SOLAS instrumentation examination of this kind. This is a professional assessment of regulatory and technical knowledge. It does not confer statutory certification, and it does not authorise you to issue SOLAS certificates or act as a surveyor on behalf of a flag State.
What is the exam format?
Multiple-choice questions plus written or essay items that are site-specific, meaning they may reference a vessel type, system configuration, or survey scenario rather than a single universal answer. The written section rewards structured reasoning and correct clause references more than memorised phrasing.
How long is the exam, and what does it cost?
Those figures are set by the official awarding body, which publishes the current duration, fee, and passing standard on its website. Check there before you plan your sitting, because published numbers change and any figure quoted by a third party may already be out of date.
How difficult is it?
The difficulty is breadth rather than trickery. Candidates who know SOLAS only as a list of chapters struggle with the written items. Those who can connect a requirement to a performance standard, a test procedure, and a survey record generally find the multiple-choice section manageable and the essays the real test.
Can I retake it, and how soon?
Retake rules, waiting periods, and any limit on attempts are set by the official body and are not uniform. Confirm the current policy on its site before booking. If a waiting period applies, use it to rebuild the domain where you lost the most marks rather than rereading everything.
What study order do you recommend?
Start with the convention framework and amendment cycle, because every later domain depends on how requirements enter force. Then work through navigation and radio equipment, fire detection and alarm, life-saving arrangements, machinery and periodically unattended machinery spaces, watertight and stability instrumentation, and finally testing, records, and human factors.
What are the most common failure modes?
Citing a chapter number without knowing the performance standard behind it. Confusing alarm, detection, and protection functions. Ignoring fault behaviour and redundancy, which the essay questions probe. And writing essays as general commentary instead of a structured answer with the applicable requirement, the evidence, and the conclusion.
How should I prepare for the written section?
Practise short answers under time pressure. For each topic, draft a paragraph covering the applicable requirement, the instrumentation involved, the test or survey evidence, and any failure mode. Have someone technical read it for precision. Vague confidence is the main reason capable engineers lose marks on essays.
Do I need sea time or a specific background?
There is no single required background stated here, and eligibility conditions belong to the official body. In practice, candidates come from shipboard engineering and electro-technical roles, surveying, classification, and systems integration. A working knowledge of on-board systems makes the scenario questions far easier to reason through.
