The STCW Convention is the international framework that determines whether a seafarer is qualified to step aboard a ship — and whether that ship can legally sail. Adopted in 1978 and comprehensively revised through the 2010 Manila Amendments, STCW establishes minimum competency standards for every rank from rating to master, every department from deck to engine to radio, and every specialised function from tanker operations to polar navigation. With 167 ratifying parties covering over 99% of world shipping tonnage, STCW certification is universally enforced — and PSC officers can detain vessels where crew cannot produce valid certificates. The convention directly addresses the human element in maritime safety: research indicates that 80-85% of maritime accidents involve human error, making standardised training the most effective prevention measure available. From January 1, 2026, new amendments require mandatory training on prevention of violence, harassment, and bullying — reflecting the convention's continuing evolution. A comprehensive review of over 400 identified gaps began in 2024, with a full revision expected by 2027. For crew managers and training officers, STCW compliance means tracking certificates across multiple types (CoC, CoP, Documentary Evidence), managing 5-year refresher cycles, ensuring flag state endorsements, and verifying that every crew member's qualifications match their assigned duties.

Convention Structure: Eight Chapters

STCW is organised into eight chapters, each covering a distinct area of maritime competence. The Convention sets general requirements; the STCW Code (Part A = mandatory, Part B = recommended guidance) provides the detailed competency tables.

I
General Provisions
Definitions, application, certification, and control provisions. IMO White List.
II
Master & Deck Department
Competency standards for OOW, Chief Mate, and Master — navigation, cargo, ship handling.
III
Engine Department
Standards for engine officers and ratings — propulsion, electrical, control systems.
IV
Radiocommunication
GMDSS operator competency — integrated with ITU Radio Regulations.
V
Special Training
Tanker (oil, chemical, gas), passenger ships, IGF Code (gas-fuelled ships), polar waters.
VI
Emergency & Safety Functions
Basic safety training, survival craft, advanced firefighting, medical care, security awareness.
VII
Alternative Certification
Provisions for integrated certification across deck and engine departments.
VIII
Watchkeeping
Fitness for duty, rest hours, watchkeeping arrangements at sea and in port.

Certificate Hierarchy: CoC, CoP & Documentary Evidence

STCW creates a three-tier certification system. Understanding which certificate type your crew needs — and who can issue it — prevents PSC deficiencies and recruitment delays. Book a Marine Inspection demo to see how certificate type tracking works across multinational crews.

Highest Level
Certificate of Competency (CoC)
Rank-specific licence allowing a seafarer to serve as Master, Chief Officer, OOW, Chief Engineer, Second Engineer, or GMDSS operator. Issued by flag state administration only — based on verified sea service, examinations, and approved training.
Chapters II, III, IV, VII
Specialised Qualification
Certificate of Proficiency (CoP)
Task-specific qualification for safety and specialised functions — basic safety training, advanced firefighting, survival craft proficiency, tanker endorsements, security duties. May be issued by approved training centres on behalf of the administration.
Chapters V, VI
Supporting Evidence
Documentary Evidence (DE)
Documentation other than CoC or CoP confirming competence — security awareness training, safety familiarisation, onboard training records. May be issued by approved organisations.
Chapter VI (awareness level)

Basic Safety Training: What Every Seafarer Needs

Under Regulation VI/1, every seafarer with designated safety or pollution-prevention duties must complete the Basic Safety Training package. This is mandatory regardless of rank — from the newest rating to the Master.

A-VI/1-1
Personal Survival Techniques (PST)
Abandonment, survival at sea, life-saving appliance operation, helicopter rescue. 5-year refresher mandatory.
A-VI/1-2
Fire Prevention & Fire Fighting (FPFF)
Fire detection, extinguishing equipment, fire party operations, breathing apparatus. 5-year refresher mandatory.
A-VI/1-3
Elementary First Aid (EFA)
Assessment, CPR, bleeding control, shock management, burns, fractures. No refresher cycle mandated by STCW.
A-VI/1-4
Personal Safety & Social Responsibilities (PSSR)
Shipboard safety culture, fatigue management, environmental awareness. From 1 Jan 2026: includes mandatory anti-harassment and anti-bullying training.
2026 Update

Watchkeeping Standards (Chapter VIII)

Chapter VIII is the operational backbone of STCW — it determines how watches are structured, what rest seafarers receive, and when the Master must be on the bridge. PSC officers check compliance during inspections.

Table 1: STCW Watchkeeping Requirements Summary
Requirement Standard Details PSC Focus
Rest hours Min 10 hrs / 24 hrs; 77 hrs / 7 days Rest may be split into max 2 periods, one of which must be at least 6 hours. Max 14-hour gap between rest periods. Daily rest records for all watchkeepers signed by seafarer and Master
Bridge watchkeeping OOW must have undivided attention Sole lookout only permitted in daylight, clear weather, no hazards, with remote alarm on radar. Master must be called immediately if in doubt. Bridge manning, lookout arrangements, radar/ECDIS usage
Engine watchkeeping Competent engineer must be on duty at all times UMS (Unattended Machinery Space) operation permitted with appropriate alarm systems and procedures. Chief Engineer determines watch arrangements. UMS alarm systems, engine room manning, emergency procedures
Port watchkeeping Adequate watch maintained at all times in port OOW responsible for safety of ship, cargo operations, security. Mooring arrangements checked regularly. Pollution prevention measures maintained. Gangway watch, cargo operations supervision, fire rounds
Fitness for duty All watchkeepers must be fit and not impaired No watchkeeper impaired by fatigue, alcohol, or drugs. Watch schedules must allow adequate rest. Drug and alcohol policies must be enforced. Evidence of fatigue, alcohol testing capabilities, rest records
Handover procedures Formal handover between relieving watches Outgoing OOW must not leave until relieving officer has fully taken over. Handover must include: position, traffic, weather, standing orders, navigation warnings. Bridge handover log, standing orders book
Never Miss a Certification Deadline
CoC tracking, CoP refresher alerts, BST expiry management, flag state endorsement monitoring, crew competency matrix — Marine Inspection automates the entire STCW certification lifecycle for every crew member across your fleet.

The 5-Year Refresher Cycle

The Manila Amendments introduced mandatory 5-year refresher training for safety-critical functions — addressing "skills fade" where over half of training content is forgotten within six months. Seafarers with 12+ months of qualifying sea service in the preceding 5 years may be eligible for abbreviated revalidation courses. Sign up for Marine Inspection to automate refresher training alerts across your crew.

2026 Amendment: Anti-Harassment Training

From January 1, 2026, STCW Table A-VI/1-4 includes a new mandatory competency: preventing and responding to violence, harassment, bullying, and sexual assault onboard. This is the most significant amendment since the Manila Amendments.

IMO Resolution MSC.560(108) — Effective 1 January 2026
New Competency Added: "Contribute to the prevention of and response to violence and harassment, including sexual harassment, bullying and sexual assault"
Training Covers: Understanding violence and harassment continuum, recognising harmful behaviours, consequences for victims and perpetrators, reporting mechanisms, bystander intervention, support resources
Who Is Affected: All seafarers completing new Basic Safety Training courses from 1 Jan 2026. Previously issued BST certificates remain valid without restriction. Refresher courses for A-VI/1-1 and A-VI/1-2 are not affected.
Company Actions Required: Verify training providers include updated PSSR module. Review SMS for anti-harassment policies. Establish open reporting mechanisms onboard and ashore. Ensure all personnel (ship and shore) are covered by appropriate support policies.

Frequently Asked Questions

What is the STCW Convention?
The International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW) was adopted in 1978 and comprehensively revised in 2010 (Manila Amendments). It establishes minimum competency standards for every seafarer on internationally trading ships. With 167 parties covering 99%+ of world tonnage, it is universally enforced through flag state certification and port state control inspections.
What is the difference between CoC, CoP, and Documentary Evidence?
A Certificate of Competency (CoC) is a rank-specific licence (Master, Chief Officer, OOW, Chief Engineer, etc.) issued only by the flag state administration. A Certificate of Proficiency (CoP) covers specialised functions like basic safety training, advanced firefighting, survival craft, and tanker operations — may be issued by approved training centres. Documentary Evidence (DE) covers awareness-level training like security awareness. A flag state endorsement is required when serving on vessels of a different flag.
What changed in STCW for 2026?
From January 1, 2026, STCW Table A-VI/1-4 includes a new mandatory competency on preventing and responding to violence, harassment, bullying, and sexual assault onboard. This applies to all new Basic Safety Training courses issued from that date. Previously issued certificates remain valid. A comprehensive STCW review addressing over 400 identified gaps began in 2024 and is expected to produce a full revision by 2027.
Which certificates require 5-year refresher training?
Personal Survival Techniques (PST), Fire Prevention and Fire Fighting (FPFF), Proficiency in Survival Craft, Fast Rescue Boats, and Advanced Fire Fighting all require refresher training every 5 years under the Manila Amendments. Seafarers with 12+ months of qualifying sea service in the preceding 5 years may be eligible for abbreviated revalidation courses rather than full modules. Elementary First Aid and PSSR do not currently require STCW-mandated refreshers.
What is the IMO White List?
The IMO White List identifies countries that have demonstrated full and complete compliance with STCW Convention requirements. Certificates issued by White List countries are internationally recognised. Certificates from non-White List countries may not be accepted for flag state endorsement, and seafarers holding such certificates may face difficulties working on internationally trading vessels. The list is maintained by IMO and updated periodically.
