There are many ways into the maritime industry. A deck cadet from Manila and an electrician retrained as an ETO from Kyiv are both following STCW pathways — but their entry requirements, training institutions, and flag-state examinations differ considerably. This hub maps the major routes: the deck and engine officer ladders from cadet to command level; specialist tracks including tankers, gas carriers, cruise, yacht, offshore, and fishing; and shore-adjacent roles in ports, VTS, classification, and maritime cyber. Pre-sea training routes vary by flag state — the pages below note where Philippine MARINA, Indian DG Shipping, Ukrainian Maradmin, UK MCA, and Norwegian Sjøfartsdirektoratet practice diverges from the international STCW floor.
How to use this hub: the three sections below group pathways by the segment you'd work in — deck and engine ladders, specialist tracks (tanker / gas / cruise / yacht / offshore / fishing), and shore-adjacent roles. For the pay trajectory underneath each pathway see the new /career-maps multi-dimensional view (deck-officer 10-year pay by vessel type, engine-room progression by fleet, niche-segment pay benchmarks). For the salary data itself by rank see /salaries; for the certificate list see /certifications; for where to train see /training-centres.
Before committing to a pathway: verify the current flag-state requirements with the issuing administration — STCW sets the international minimum, but individual flags impose additional examinations, sea-time minimums, and medical standards. Pre-sea training is a multi-year commitment with sea-time gates that can't be shortcut; the choice of flag-state CoC determines which international berths will accept you for decades after.

Always verify current requirements with the issuing flag-state administration before committing to a training programme.
