Which statement best describes the STCW Code's relevance to port state control?

• A. It primarily governs environmental standards at sea.
• B. It sets minimum competency standards for seafarers, which PSC checks through certificates and training records.
• C. It prescribes ship's speed limits in traffic separation schemes.
• D. It defines crew muster lists.

Answer: (B)

The STCW Code sets the minimum standards of competence, training, and certification that seafarers must meet for their respective roles. Port State Control uses those standards as the benchmark for inspecting ships, checking that crew members hold valid Certificates of Competency and the required training records, and that endorsements and refresher training are up to date. This directly ties the Code to PSC activities, since PSC aims to ensure every vessel has qualified personnel in place and that documentation supports their qualifications. Other options point to environmental rules, speed regulations, or muster requirements, which are governed by different rules and do not describe STCW’s role in PSC.
