TS 13054

TS 13054 is a professional standard that defines the occupational scope of the officer performing the restricted master role. In maritime practice, a restricted master is a commanding officer with defined authority and responsibility for vessel operation, including safe navigation, communications, regulatory compliance, and operational decision-making.

Where the role sits in maritime practice

This standard frames the restricted master role within a formal competence structure rather than as a simple job title. Its references to STCW, national seafarer regulations, collision-avoidance rules, and related maritime sources place the occupation in the wider system of watchkeeping, voyage safety, emergency awareness, and disciplined bridge operations. In general technical terms, a master must combine navigational judgement, crew coordination, and timely response to operational risks to keep the vessel safe and compliant.

Competence, assessment, and equipment use

The scope indicates that the standard addresses professional qualifications, evaluation, and testing criteria for the role, together with the tools and equipment used in the occupation. Conceptually, that means the standard is meant to define what a competent restricted master should know and be able to do, and how that competence is judged. The title and scope point toward practical maritime equipment and communication aids as part of the work, but they do not by themselves establish detailed test procedures or numerical limits.

• Focused on the restricted master occupation in maritime work.
• Connected with voyage management, navigation safety, and shipboard communication.
• Aligned in general with STCW-based seafarer competence concepts and national maritime rules.
• Recognises that tools and equipment form part of the occupational competence profile.
