Certification and career guide
Seafarer Training
Every rank at sea is built on the same chart: mandatory safety training, logged sea service, and examined competence. This guide sets out the STCW requirements, the certificates behind each step, and how officers progress from cadet to command.
5 stages
Basic safety · Cadetship · Operational · Management · Specialised
What STCW actually requires
The International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW), adopted by the IMO in 1978 and heavily amended in Manila in 2010, sets the minimum training every seafarer must hold. Flag administrations issue the certificates; the convention fixes the standard of competence behind them. No seafarer may be assigned shipboard duties before completing STCW Basic Safety Training.
STCW A-VI/1-1
Personal survival techniques
Abandon-ship drills, lifejackets, liferafts, survival at sea and cold-water response.
STCW A-VI/1-2
Fire prevention and fire fighting
Fire theory, extinguishers, breathing apparatus and shipboard fire parties.
STCW A-VI/1-3
Elementary first aid
Immediate care of casualties, bleeding, burns, shock and resuscitation on board.
STCW A-VI/1-4
Personal safety and social responsibilities
Emergency signals, safe working practice, pollution prevention and life on board.
The certification pathway
Deck and engine careers run in parallel: the same structure of approved training, logged sea service and examination, with different technical syllabuses. Exact sea-time figures and examination formats are set by your flag administration — always confirm with the issuing authority before booking a course.
Stage 01
Entry and basic safety
Before a first sea voyage every seafarer completes STCW Basic Safety Training and holds a valid medical certificate.
- STCW Basic Safety Training (the four short courses listed above).
- Seafarer medical fitness certificate and, where required, a national seafarer's identity or discharge book.
- Security awareness or designated security duties under STCW Chapter VI.
- Ship-specific familiarisation on joining, recorded before assuming any watch duty.
Stage 02
Cadetship and sea service
Officer candidates combine approved college study with supervised sea time recorded in a training record book.
- Approved education programme covering navigation or marine engineering knowledge.
- Typically 12 months of approved sea service, with a set period of bridge or engine-room watchkeeping.
- Training record book signed by the shipboard training officer for every completed task.
- Watchkeeping practice under STCW Chapter VIII rest-hour and fitness-for-duty rules.
Stage 03
Operational level certificate
The first certificate of competency: Officer of the Watch (deck) or Engineer Officer of the Watch (engine).
- Deck: STCW Regulation II/1 — Officer in charge of a navigational watch on ships of 500 GT or more.
- Engine: STCW Regulation III/1 — Officer in charge of an engineering watch in a manned engine room.
- Ancillary certificates: radar and ARPA, ECDIS, GMDSS radio operator, medical first aid, advanced fire fighting, survival craft.
- Written and oral examinations plus approved simulator assessment set by the flag administration.
Stage 04
Management level certificate
After further sea service in charge of a watch, officers upgrade to Chief Mate / Master or Second / Chief Engineer.
- Deck: STCW Regulation II/2 — Master and chief mate on ships of 500 GT or more.
- Engine: STCW Regulation III/2 — Chief engineer and second engineer on main propulsion of 3000 kW or more.
- Management subjects: stability and cargo planning, ship handling, ISM, maritime law and bridge or engine-room resource management.
- Leadership and teamwork competence assessed as part of the certificate, not only technical knowledge.
Stage 05
Specialised and vessel-specific training
Trade and equipment endorsements sit on top of the certificate of competency and decide which ships you can serve on.
- Tanker familiarisation and advanced oil, chemical or liquefied-gas cargo operations (STCW Chapter V).
- Dynamic positioning: the Nautical Institute DPO scheme — induction, sea time, advanced, final assessment.
- Polar Code, high-speed craft, passenger-ship crowd and crisis management as the trade requires.
- Company-specific simulator training, LSA or machinery type courses and refresher revalidation every five years.
Career progression for officers
Deck department
- Deck cadet — approved study and training record book
- Third / Second Officer — Officer of the Watch, STCW II/1
- Chief Officer — cargo, stability and stowage responsibility, STCW II/2
- Master — command, ISM accountability and overall safety of the ship
Engine department
- Engine cadet — approved study and workshop skills
- Fourth / Third Engineer — Engineer Officer of the Watch, STCW III/1
- Second Engineer — maintenance planning and engine-room operations, STCW III/2
- Chief Engineer — technical management of the whole machinery plant
Certificates and endorsements are revalidated every five years, normally on evidence of recent sea service plus refresher training in survival craft and fire fighting. Keep the training record, sea service testimonials and course certificates together — promotion examinations depend on that paperwork as much as on knowledge.
