Third Officer (3rd Officer) is the most junior deck officer on a merchant ship — the first bridge rank after graduating as a cadet. The job covers navigational watchkeeping, maintaining the ship’s life-saving and fire-fighting appliances, and supervising cargo operations during port watches. Even as the most junior officer, a Third Officer’s pay is several times a rating’s wage. Here is the Third Officer salary breakdown per month in 2026.
Average Third Officer Salary: US$3,656 per Month
Maritime Zone’s October 2026 vacancy data puts the average Third Officer offer across the merchant fleet at US$3,656 per month (September 2026 average). Individual offers vary widely — from US$1,800 on general cargo ships to over US$6,500 on LNG carriers and SOVs — depending on ship type, company, and experience. As a floor: any foreign-going Third Officer offer below US$2,000 per month should be treated with suspicion, since it sits far below the 2026 market range.
Third Officer Salary by Ship Type (2026 Estimates)
The figures below are estimated total monthly earnings (basic wage + average overtime) based on 2026 vacancy data:
| Ship Type | Estimate per Month | Notes |
|---|---|---|
| LNG/LPG carrier | $4,000 – $6,000 | Highest; gas endorsement V/1-2 required |
| Oil tanker | $3,000 – $4,800 | Standard tanker; SIRE and cargo ops |
| Chemical tanker | $3,500+ | October 2026 vacancies: $3,500 – $3,600 |
| Offshore (OSV/AHTS/SOV) | $3,500 – $5,500 | SOVs pay most in the offshore class |
| Cruise ship | $3,000 – $5,000 | 6–8 month contracts, long hours |
| Container ship | $2,500 – $4,000 | Stable liner routes, good for new 3/Os |
| Bulk carrier | $2,000 – $3,000 | Largest segment for new 3/Os |
| Ro-Ro / general cargo | $1,800 – $3,000 | Maritime Zone average $2,974/month |
For comparison, Maritime Zone records a September 2026 average Third Officer offer of US$3,656/month, with LNG carriers and SOVs offering up to US$6,545/month. Compare with the deck rank below in Bosun salary 2026 and all ranks in the seafarer salary guide 2026.
What a Third Officer Does Day to Day
The Third Officer is far more than a “watchkeeper” — this officer owns the ship’s safety equipment:
- Navigational watchkeeping. 8 hours on the bridge (typically 08:00–12:00 and 20:00–24:00), monitoring position, traffic, and weather.
- Life-saving and fire-fighting appliances (LSA/FFA). Lifeboats, life rafts, extinguishers, EPIRBs, and SARTs are this officer’s responsibility — inspected regularly and logged.
- Safety drills. Preparing and documenting fire, abandon ship, and man overboard drills.
- Port watches. Supervising cargo operations, stability, and ship security alongside.
- Navigational publications. Correcting charts, books, and publications to keep them up to date.
Requirements to Become a Third Officer
- CoC STCW II/1 (OICNW). Certificate as Officer in Charge of a Navigational Watch, plus cadet sea service.
- Basic Safety Training (STCW VI/1), AFF, MFA, SCRB. The mandatory safety certificate package for deck officers.
- ECDIS and GMDSS. Generic and type-specific ECDIS certificates; a GMDSS (GOC) certificate is a major plus.
- English. Bridge communication and ship documents are in English — a Marlins/CES score above 60% is standard at many companies.
- Segment endorsements. Tanker V/1-1, gas V/1-2 — these endorsements are what separate a $3,000 offer from a $5,000 one.
Third Officer Pay Structure
- Basic wage — the base salary; for foreign-going 3/Os typically $2,000–$3,500.
- Overtime — hourly overtime; port watches and drills add significant overtime hours.
- Leave pay — leave compensation accumulated during the contract.
- Special allowances — tanker, gas, or high-risk trading-area allowances at some companies.
Always ask for the written pay breakdown before signing a contract — never judge an offer by a single “salary per month” figure.
4 Factors That Change a Third Officer’s Pay
- Ship type. Gas and offshore vessels pay most in the 3/O class because of extra certification and standards.
- Endorsements held. A 3/O with a gas (V/1-2) or tanker (V/1-1) endorsement commands far more than a dry-cargo 3/O.
- Flag and CBA. Ships under ITF/IBF agreements generally pay above the minimum — see our ITF/IBF/ILO wage standards explainer.
- Company and crewing agent. Large international operators tend to follow ITF scales; small domestic operators often pay below them.
Career Path: from Third Officer to Captain
- Third Officer → Second Officer. After 12 months of watchkeeping service as 3/O, the path to 2/O opens — the rank that owns voyage planning and ECDIS.
- Second Officer → Chief Officer. Requires a management-level CoC (STCW II/2) and cargo-operations experience.
- Chief Officer → Master. The top of the deck ladder; from 3/O to captain typically takes 10–15 years of sea service.
How to Check Whether an Offer Is Fair
- Compare with the market floor: a foreign-going 3/O offer below US$2,000/month is not reasonable.
- Ask for it in writing: basic wage, hourly overtime rate, leave pay, and allowances must appear in the Seafarer Employment Agreement.
- Watch for unclear deductions: a contract allowing unilateral deductions without a clear mechanism is a red flag.
- Check the ship’s flag: read our flag state explainer before sign-on.
- Beware of job scams: officer ranks are prime targets for brokers because the pay is high — read the seafarer job scam red flags before paying anything.
