Merchant navy officers who want to move into offshore platform work start in a better position than most people assume. What you already have is relevant. The gaps are specific and fixable.
What You Bring That Matters
DP certification is the most valuable thing you can arrive with. If you have accumulated DP sea time on a Nautical Institute logbook and hold the full certificate, you are starting the transition with the most sought-after qualification in the floating unit marine department sector. Offshore operators who need DP officers do not care whether you built that time on a PSV or a cargo ferry.
STCW engineering management certificates transfer directly. Chief engineer qualifications, second engineer, electro-technical officer competency: all of it is recognised on FPSOs and semi-submersibles. The machinery is different from a bulk carrier. The certificate framework is the same.
Something less tangible but genuinely valued: the safety culture. Merchant navy officers arrive already familiar with permit to work systems, incident reporting, watchkeeping discipline. Offshore platform operators spend less time onboarding someone who already has this in their background.
What You Actually Need to Add
BOSIET. Basic Offshore Safety Induction and Emergency Training. Mandatory for UK sector work. Covers helicopter escape, sea survival, firefighting and first aid in the offshore context. Three to four days. Get it done before you apply because operators ask about it immediately.
HUET may be included in the BOSIET or may be a separate requirement depending on the operator and region. Check what applies to your specific target before booking training.
Medical fitness for offshore. The ENG1 covers seafarer fitness. Offshore work in the UK sector specifically requires an OGUK medical. Different criteria, needs separate assessment. Some regions have their own equivalent.
Applying
Manning agencies that specialise in offshore rather than deep sea cargo are where to start. The agencies that exclusively handle offshore operators have the relationships that produce results. A deep sea cargo agency occasionally has an offshore position. An offshore specialist agency has them consistently.
Direct applications to FPSO operators and drilling contractors work alongside the agency approach. SBM Offshore, BW Offshore, Transocean, Valaris: crewing departments at all of them receive direct applications from merchant navy officers making the transition. Be clear about what you are and what you are seeking. Merchant navy chief officer, full DP certificate, seeking floating unit marine department role: that framing is useful. Generic applications that do not acknowledge the transition tend to get treated like any other unsolicited CV.
Where People Go Wrong
Applying for senior positions straight away. A cargo ship chief officer with no offshore experience is not the obvious candidate for chief officer on a large FPSO. Entering at second officer level, building offshore sea time, then moving to chief officer within the sector: this takes longer in the short term and produces better results in the medium term.
Not completing the BOSIET before applying. The certificate takes a few days and costs a few hundred pounds. Showing up in a recruiter’s inbox without it when the recruiter’s first question will be whether you have it suggests you have not thought the transition through.
Overstating the equivalence of deep sea experience and offshore experience. They are not the same. Operators know what offshore experience looks like. Acknowledging the transition and positioning your deep sea background as relevant context rather than direct equivalence makes a better impression.
