TS 12977

TS 12977 is a vocational standard concerned with the role of the chief officer. In marine practice, the chief officer is the senior deck officer after the master, typically responsible for navigation support, deck operations, crew coordination, cargo-related duties, and the day-to-day operational order of the vessel. The standard focuses on defining the professional framework for people performing this occupation, especially their qualifications and the basis for assessment.

Operational and managerial context of the role

In general technical terms, chief officer duties go beyond seamanship alone. The role usually combines navigational awareness, task planning, record keeping, supervision of deck personnel, and attention to safety and operational discipline. Depending on vessel type and company practice, responsibilities may also include watchkeeping, cargo planning, emergency readiness, and coordination of work on deck. The scope indicates that the standard addresses classification, specifications, qualifications, and evaluation/testing criteria for the occupation, along with the tools and equipment used in the profession.

What this standard does and does not define

This is a professional standard rather than a product specification. It describes the competence profile of a chief officer, not the technical design of shipboard equipment. By framing the occupation through categories, qualifications, and assessment criteria, the standard provides a common reference for understanding what the role entails. The referenced TS and TS EN documents point to the wider maritime technical environment in which this profession operates, including communication and navigation-related standards.
