What Is STCW? Why Seafarers Need It, the Courses You Must Take, and Renewal

In brief

  • STCW is the international convention on standards of training, certification and watchkeeping for seafarers, produced by the International Maritime Organization (IMO). It was adopted on 7 July 1978 and entered into force on 28 April 1984.
  • The basic training everyone working onboard must pass is Basic Safety Training, made up of 4 courses: Personal Survival Techniques, Fire Prevention and Fire Fighting, Elementary First Aid, and Personal Safety and Social Responsibilities.
  • In Thailand, the Marine Department issues certificates to people who pass courses at approved training schools. Princess states that Security Awareness is required for every cruise ship crew member.
  • A Certificate of Proficiency (CoP) under Marine Department Notice 256/2565 is valid for 5 years from issue and is renewed with proof of sea service or a refresher course.
  • Course fees and length differ by school. We found no official standard price list, so we give no figures: ask for a written quotation from a school on the Marine Department's approved list.

When you read a seafarer job advertisement you often see "STCW required". This article explains what STCW is in plain language, based on the IMO convention page and the guidance pages of the Marine Department's Seafarers Standard Division. Information checked on 2 November 2026.

What is STCW?

STCW stands for the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers. The IMO created it to set minimum standards for the training, certification and watchkeeping of seafarers. According to the IMO's STCW convention page, the 1978 convention was the first to set these basic requirements at international level.

Because countries apply the same standard, certificates held by Thai seafarers are recognised on foreign ships, and employers and ports can check that crew were trained to the required level. The list of countries the IMO has confirmed as fully implementing the convention is published as document MSC.1/Circ.1163. We have not opened the current version to confirm Thailand's status, so we do not state it in this article.

The basic course everyone needs: Basic Safety Training

The UK government's guidance page says everyone working on a ship, in any capacity, must complete 4 basic parts set out in the tables of Chapter VI of the STCW Code. In Thailand, the Marine Department calls this group the "four basic courses (Basic Safety Training)" in its list of certificates you can apply for. The table below shows the 4 parts.

Components of Basic Safety Training under the STCW Code

Personal Survival TechniquesA-VI/1-1Surviving when you have to abandon ship
Fire Prevention and Fire FightingA-VI/1-2Preventing and fighting small fires onboard
Elementary First AidA-VI/1-3Basic first aid

We cite the UK MCA page because it names all 4 parts and their tables clearly. The text of the STCW Code is an IMO requirement; its application in Thailand falls under Marine Department regulations and notices.

Additional courses by position

The Marine Department's guide to applying for COP/COE/GOC/COR certificates lists 21 certificates you can apply for. The table below picks examples relevant to cruise ship and cargo ship work.

Examples of certificates in the Marine Department list
Certificate (English name as on the guide page)Condition stated in the guide
Basic Safety Training (four basic courses)If trained more than 5 years ago, you must show proof of a refresher course
Security Awareness for All SeafarersNo extra condition stated
Designated Security Duties for All SeafarersNo extra condition stated
Advanced Fire FightingIf trained more than 5 years ago, you must show proof of a refresher course
Survival Craft (lifeboats and rescue boats other than fast rescue boats)At least 6 months of sea service on ships of 500 GT or more, and a refresher if trained more than 5 years ago
Ship's CookAt least 6 months of sea service on ships of 500 GT or more, and you must attach a course from the Department of Skill Development
Crowd Management / Crisis Management and Human BehaviorNo extra condition stated (courses relating to passenger ships)
Basic Training on Tankers (Oil and Chemical)You must hold a valid Basic Safety Training certificate

Cruise lines describe STCW differently. Princess states that STCW Security Awareness is required for every cruise ship crew member, and that the seafarer's book and STCW are required for some positions (mostly deck and engine). MSC says its pre-boarding training supplements the mandatory STCW training. Before paying tuition, ask the company or read the job advertisement to see which courses that position needs.

How long is a certificate valid, and how do you renew it?

Under Marine Department Notice 256/2565 (Royal Gazette, 3 January 2023), Certificates of Competency (CoC) and Certificates of Proficiency (CoP) issued under Chapters 2 and 3 are valid for 5 years from the date of issue. For basic safety training, survival craft and rescue boats, fast rescue boats and advanced fire fighting, renewal requires one of the following, plus a valid health certificate:

  • Proof of at least 12 months of sea service in an appropriate role in the previous 5 years, or at least 3 months in the 6 months before expiry, together with proof of onboard drills (for example a Muster List), or
  • Proof of passing a refresher course approved by the Marine Department, taken no more than 5 years before the renewal application.

Choose a school approved by the Marine Department

A certificate can only be issued if you passed a course at a training school approved by the Marine Department. The Seafarers Standard Division's page on approved training schools collects the latest notices, for example Marine Department Notice 195/2569 (approved schools and courses, STCW category) and 196/2569 (courses outside the STCW convention), including lists of instructors. The page links to documents rather than listing schools on one page, so open the latest notice file.

One example of a state institution offering this group of courses is the Maritime Training Centre (MMTC), which groups its courses into categories such as basic seafarer knowledge, passenger ships, liquid cargo and dangerous goods ships, and security officer courses. The page does not state course length or fees; ask the institution directly.

Check before you pay tuition

  • The school and course are in the Marine Department's latest notice of approved training schools
  • The course matches what the job advertisement or company specifies, not just any "short course"
  • Get a written quotation and schedule (fees and length differ by school)
  • Ask whether the school files the certificate application with the Marine Department for you, and whether the Department's fee is separate from tuition
  • After you receive the certificate, verify it through the verify.md.go.th system
