How often must STCW training be updated or renewed?

The STCW (Standards of Training, Certification, and Watchkeeping for Seafarers) training requires renewal or updates every two years. This interval is set to ensure that mariners maintain up-to-date knowledge and skills in safety, ship operations, and emergency procedures, which are critical in maintaining safety at sea. Regular updates help ensure crew members are familiar with any changes in regulations, technologies, and best practices that may have emerged since their last training. The two-year requirement is designed to keep mariners compliant with international standards and ready to respond effectively to any maritime situations that may arise.
