The «Navigation (NA) Operational Level» subject covers both theoretical and practical knowledge regarding safety when working with electrical equipment. Mastery of this information is a key indicator of an employee's competence in their specific role on a vessel. As a 3rd officer responsible for navigation duties, your primary tasks include assisting senior officers in planning the ship’s voyage by calculating safe passage routes, preparing navigation charts, and monitoring weather conditions. You are also responsible for conducting regular safety checks on all life-saving equipment to ensure it is in good working order, as well as operating and maintaining navigational equipment like radar, GPS, and compasses to ensure they are functioning correctly.
