What Is STCW?

The Standards of Training, Certification and Watchkeeping for Seafarers (STCW) is an international convention adopted by the International Maritime Organization (IMO) in 1978 and significantly updated in 1995 and again in 2010 (the "Manila Amendments"). It sets the minimum qualification standards for masters, officers, and watch personnel on seagoing vessels.

Simply put: if you want to work at sea on a commercial vessel, STCW certification is not optional — it is a legal requirement under international law, and ships that carry improperly certified crew can be detained by port state control.

The STCW Basic Safety Training Package

For anyone entering the maritime industry, the starting point is the STCW Basic Safety Training package, often called the "Basic Safety" or "BST" package. This consists of four core courses:

  1. Personal Survival Techniques (PST): Survival at sea, use of life-saving appliances, abandoning ship procedures.
  2. Fire Prevention and Firefighting (FPFF): Firefighting principles, use of portable extinguishers, breathing apparatus, and shipboard firefighting procedures.
  3. Elementary First Aid (EFA): Basic first aid including CPR, wound management, and emergency response.
  4. Personal Safety and Social Responsibilities (PSSR): Safety culture on board, emergency procedures, environmental awareness, and human relationships at sea.

These four certificates are required for virtually all seafarers working on vessels of 500 GT or more on international voyages.

Additional STCW Certificates You May Need

Depending on your role, vessel type, and area of operation, additional STCW certificates will be required:

  • Proficiency in Survival Craft and Rescue Boats (PSCRB): Required for officers and those who may be in charge of a survival craft.
  • Advanced Firefighting: Required for officers with firefighting responsibilities.
  • Medical First Aid / Medical Care: Required for designated crew with medical response duties.
  • GMDSS (Global Maritime Distress and Safety System): Required for radio operators and deck officers on GMDSS-equipped vessels.
  • Proficiency in Security Awareness / Designated Security Duties: Required under ISPS Code compliance.
  • Crowd Management / Crisis Management: Required for personnel working on passenger vessels.
  • Tanker Familiarization / Advanced Tanker Training: Required for crew on oil, chemical, or LNG tankers.

How Long Are STCW Certificates Valid?

Most STCW certificates are valid for five years, after which they must be revalidated through refresher training or by demonstrating continued sea service. It is the seafarer's responsibility — and their employer's — to keep all certificates current. Expired certificates are a common reason for crew members being removed from vessels during port state control inspections.

Where to Get STCW Training

STCW training must be completed at an approved maritime training center recognized by your flag state authority. When choosing a training center, verify that:

  • The center is approved by your country's maritime authority (e.g., MCA in the UK, USCG in the US, MARINA in the Philippines)
  • Certificates issued will be recognized internationally
  • The course content and delivery meet IMO model course standards

Building Your Certificate of Competency (CoC)

STCW basic training is just the foundation. To progress to officer and master roles, seafarers must obtain a Certificate of Competency (CoC), which requires a combination of approved sea service, maritime education (cadetship or equivalent), and examination by the flag state authority.

The pathway typically looks like this:

  1. Complete STCW Basic Safety Training
  2. Join a vessel as a rating or cadet, accumulating approved sea service
  3. Complete a maritime academy program
  4. Pass flag state examinations for Officer of the Watch (OOW)
  5. Continue sea service and progress to Chief Mate, then Master

Final Advice for New Seafarers

Keep copies of all your certificates in both physical and digital formats. Many seafarers use secure cloud storage to ensure their documents are accessible even if originals are lost. Start building your sea service record from day one — every day at sea counts toward your next qualification milestone.
