The STCW Convention
The International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW) is an international convention established by the International Maritime Organization (IMO). It sets out the minimum levels of training, certification and watchkeeping for seafarers, together with the administrative arrangements behind them, and has been adopted by the majority of the maritime nations of the world.
All coastal states have the power to check that seamen on visiting vessels hold the appropriate certificates and training required under the convention. This is enforceable under Port State Control.
Origins and revisions
| Milestone | What changed |
|---|---|
| 1978 | Original convention adopted by the IMO; the first attempt to set a global minimum standard for seafarer training. |
| 1995 (STCW 95) | A comprehensive revision that replaced general principles with detailed standards of competence, added the STCW Code in two parts, and introduced the IMO White List of fully compliant administrations. |
| 2010 (Manila Amendments) | The latest major revision — adopted in Manila, in force since 2012. It updated rest-hour rules, added modern training requirements (ECDIS, leadership and teamwork, security awareness) and tightened revalidation. |
So when colleagues say "STCW 95", they are usually referring to the 1995 revision; the convention in force today is the STCW Convention, as amended, including the Manila Amendments of 2010.
How the convention is organised
- Chapters I–VIII of the convention cover the general provisions, master and deck department, engine department, radiocommunication operators, special training for tankers, emergency and safety training, alternative certification, and watchkeeping.
- Part A of the STCW Code carries the mandatory minimum standards of competence; Part B gives recommended guidance.
- Flag administrations issue the certificates of competency; the convention fixes the standard of competence behind them and requires parties to confirm that other parties' certificates meet the same minimums.
Watchkeeping standards
Chapter VIII is the reason watchkeepers should read the convention directly. It requires administrations to direct attention to the dangers of watch mismanagement, to set rest periods, and to ensure that:
- the watch can call the master without hesitation whenever the situation demands;
- the officer in charge of the watch is not assigned duties that interfere with lookout or navigation;
- fitness for duty — alcohol, fatigue, medication — is controlled before a watch is taken over.
Enforcement: Port State Control
The convention does not depend on flag-state inspection alone. Under Port State Control (PSC), officers of a coastal state may board foreign vessels in their ports and verify that every seafarer holds a valid, appropriate certificate under the STCW convention.
- Deficiencies in certification, or in watch arrangements, can lead to detention of the vessel until they are rectified.
- STCW control provisions also allow the port state to assess a seafarer's professional competence when there are clear grounds, and to require corrective training or reassignment.
- Consistent STCW-related detentions feed a vessel's PSC record and can move it into a more intensive inspection regime.
For the practical training-and-certification pathway built on this convention — from Basic Safety Training to Master and Chief Engineer — see the Seafarer Training guide.
Where STCW is enforced: Port State Control
The Convention's checks are not theoretical. Coastal states verify certificates, manning, rest hours and demonstrated competence through Port State Control inspections — and detain ships that fall short. See the companion lesson: Port State Control: How Coastal States Enforce Standards.
