The STCW Code

Part A (mandatory) & Part B (guidance)

The two halves of the STCW Code

When STCW was overhauled in 1995, the technical standards were lifted out of the Convention itself and placed in a separate STCW Code. That Code has two parts: Part A (mandatory minimum standards) and Part B (recommended guidance). The 2010 Manila Amendments tightened both — adding ETO, ECDIS, leadership, security, hours of rest and refresher training.

Code A — Mandatory

Minimum standards every Party MUST enforce

Chapter IIDeck Officers — OOW, Chief Mate, Master (Reg. II/1, II/2)
Chapter IIIEngineers + ETO (Reg. III/1, III/2, III/6, III/7)
Chapter IVRadio personnel — GMDSS GOC / ROC (Reg. IV)
Chapter VTankers, passenger ships, polar, IGF specialised training
Chapter VIBasic safety, PSCRB, AFF, MFA, Security (Reg. VI/1–VI/6)
Chapter VIIAlternative certification
Chapter VIIIWatchkeeping — hours of rest, fitness for duty
⚠ Failure to apply Part A = the Party is removed from the IMO "White List" of compliant administrations.

Code B — Recommended

✓ Although technically "recommended", most quality flag States and MET institutions apply Part B as if it were mandatory — port-State Control inspectors look for it.

Why both Codes apply almost everywhere

Quality MET institutions teach to Part A and Part B because:

  • Flag administrations use Part B as the basis of their model courses.
  • Port-State Control (Paris MoU, Tokyo MoU, USCG) inspects CoCs and CoPs against the full Code.
  • A seafarer with a Code-B-aligned CoC is hireable on any foreign-flag vessel; an A-only CoC is not.
  • The IMO STCW White List is published only after audits confirm both parts are applied.

Worldwide application

Most member States apply both Codes — to their MET institutions and to every ship in port

MET institutions

Maritime Education & Training centres must align syllabi, instructor qualifications, simulators and Training Record Books with Part A and Part B for course approval.

Own-flag ships

Flag administrations issue CoC / CoP only after the candidate has met the full STCW Code, then revalidate every 5 years with refresher training (Reg. I/11).

Foreign-flag ships in port

Port-State Control (Paris MoU, Tokyo MoU, USCG, IOMoU…) verifies that every seafarer on a visiting ship holds STCW certificates compliant with both Code parts. Non-compliance = detention.
