International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW)
Status: In force — the global standard for seafarer training, certification, and watchkeeping, from competency tables to rest hours.
What Is It?
The STCW Convention sets the global baseline for the training, certification, and watchkeeping standards of seafarers, ensuring that officers and ratings serving on seagoing merchant ships are qualified and fit for their duties. Its regulations and the associated STCW Code define competency standards by function and level of responsibility — navigation, cargo handling, engineering, electrical and electronic control, maintenance, radiocommunications, and ship management — each with detailed tables of competence, knowledge, and assessment criteria.
The 2010 Manila amendments comprehensively modernized the convention: introducing mandatory rest-hour requirements aligned with MLC, new certification for able seafarers and electro-technical officers, security training requirements, refresher training obligations, updated medical fitness standards, and explicit recognition of simulator-based training and assessment for competencies including bridge resource management and engine-room operations.
For fleet operators, STCW compliance is a living workforce discipline rather than a one-time certification: every certificate of competency and proficiency carries validity windows and revalidation requirements, flag state endorsements must match the vessel's flag, and safe manning documents tie required competencies to each ship. The IMO is conducting a comprehensive review of the convention to address emerging needs — alternative fuels, automation, and digital skills — meaning training obligations will continue to expand through the decade.
Who It Affects
STCW applies to seafarers serving on seagoing merchant ships flying the flag of a party to the convention — effectively the entire global fleet, as the convention is near-universally ratified. Flag administrations issue and endorse certificates, maritime education and training institutions deliver approved programs, and companies carry the obligation to ensure seafarers assigned to their ships are certificated, familiarized, and working within rest-hour limits. Port state control verifies certification and watchkeeping compliance on foreign tonnage, applying no-more-favourable-treatment to non-party flags.

Requirements
- Ensure every officer holds a valid certificate of competency for their function and level, with the correct flag state endorsements
- Verify certificates of proficiency for ratings, able seafarers, and special duties (tankers, polar waters, high-voltage, ECDIS as applicable)
- Complete mandatory basic safety training and required refresher training within five-year validity cycles
- Comply with STCW rest-hour requirements and maintain compliant watchkeeping schedules and records
- Ensure security training and familiarization per STCW VI/6 for all seafarers with and without designated security duties
- Confirm valid medical fitness certificates issued under recognized standards
- Match onboard manning and competencies to the vessel's safe manning document at all times
- Use approved training programs — including recognized simulator-based training and assessment — with auditable competency records
Penalties & Non-Compliance
Deficient or fraudulent certification is a detainable deficiency in every port state control regime, and watchkeeping or rest-hour violations regularly appear in detention statistics and casualty findings. Companies employing uncertificated seafarers face flag state sanctions and acute liability exposure — a casualty involving improperly certificated crew undermines insurance cover and limitation defences. For seafarers, invalid or expired certificates mean immediate removal from safe manning calculations; for operators, systemic training gaps surface in vetting inspections and TMSA assessments, directly affecting commercial acceptability.
