The shared STCW pathway
All international deck officers follow the same regulatory ladder: STCW Regulation III/1 (Officer of the Watch on ships of 500 GT or more), then III/2 (Chief Mate and Master on ships of 3,000 GT or more). The minimum sea-time + course-time gates between certificates are set by the seafarer's flag administration but follow the STCW Convention's floor. The real career variation is which vessel segment you accumulate sea time on, and which segment you eventually take command in.
Years 0-2 — Cadet to OOW
Cadet pay is sponsorship-dependent — most international shipping companies (Maersk, Carnival UK, BP Shipping, V.Ships, Anglo-Eastern, Bernhard Schulte) sponsor cadets with a training allowance during sea phases. Pay scales jump significantly on promotion to OOW: roughly US$3,500-4,500/month on the ITF/IBF deep-sea scales, with modest variation by segment. Container and LNG OOW pay tracks slightly above bulk and tanker at this level.
Years 2-5 — OOW to Chief Mate
Chief Mate pay reflects vessel segment more visibly: LNG and gas-carrier Chief Mate pay can run US$8,000-10,000/month, while Handysize bulk Chief Mate pay stays closer to US$6,000-7,000. The reason is cargo complexity — gas carriers and chemical tankers require type-specific Endorsement (V/1-1, V/1-2), which limits the pool of qualified officers and supports higher pay.
Years 5-10 — Master command
Master pay is where segment matters most. Master on a Handysize bulker: roughly US$10,000-12,000/month. Master on a Capesize: US$12,000-14,000. Master on a VLCC: US$14,000-16,000. Master on an LNG carrier: US$16,000-20,000+. The same officer with the same Master Unlimited CoC earns dramatically different money depending on which trade they end up in. Most officers cluster around one segment for career consistency — the credential transfers but the practical experience and operator preference don't.
How to optimise — choose your trade early
If pay is the primary career objective, the deck-officer path that maximises earnings is: cadet → OOW on bulk or container → Chief Mate on tanker (move sectors for IGF Code / IMDG / Tanker endorsements) → Chief Mate on gas → Master on LNG carrier. Each sector move adds an endorsement and broadens the credential. Alternatively the slower-but-stable path is: stay in one segment from cadet through Master, accumulating company-specific seniority. Both work; the trade-off is between credential breadth (higher peak pay) and operator continuity (lower transition risk).
