STCW training is a legal requirement for seafarers working on internationally trading vessels. Find out which courses apply to your role and how to keep your certification current.

STCW training covers the mandatory safety, operational, and watchkeeping competencies required of seafarers under the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers. Completion of the required STCW training courses is a legal prerequisite for working on internationally trading vessels and must be maintained throughout a seafarer's career.

STCW certificates have a validity period, typically five years, after which seafarers must complete refresher training to revalidate. Refresher courses cover the key competencies required under the current convention and are shorter in duration than the original certification programme.

Some elements of STCW training can be completed online, allowing seafarers to study theoretical content before attending practical assessments. E-learning delivery is subject to approval by the relevant flag state or maritime authority.

STCW comprises mandatory and optional certifications across multiple chapters of the convention. These cover areas including navigation, engineering, cargo handling, passenger ship safety, security, and medical care, with requirements varying by vessel type, rank, and trading area.

Most STCW certificates are valid for five years. Revalidation requires seafarers to demonstrate continued sea service and to complete approved refresher training before their certificate expires. Allowing an STCW certificate to lapse means a seafarer is no longer legally certified to work on an internationally trading vessel.
The specific renewal requirements vary by certificate type. Some certifications can be revalidated through refresher training alone, while others require both refresher training and evidence of approved sea service within a defined period.
