Question 66 RVR04 - Master or Mate of LT 200 GRT

The Correct Answer is C **Why Option C is Correct:** Inflatable liferafts are critical lifesaving appliances that rely on complex inflation systems and must maintain structural integrity and proper functioning of their packed contents (survival gear, rations, signaling devices, etc.). Regulatory bodies (such as the IMO/SOLAS and national maritime authorities like the USCG) mandate that these liferafts must be regularly inspected and serviced by certified personnel working at facilities specifically approved by the manufacturer and/or the relevant maritime administration. This typically requires the liferaft to be sent ashore to the approved maintenance station, usually on a schedule of every 12 months, or as dictated by the specific inspection regime (e.g., maximum 12 months, though some regulations allow for 30-month intervals between some servicing rounds if approved for extended service). **Why Other Options Are Incorrect:** * **A) Have them serviced by the shipyard annually:** While the shipyard might coordinate the service, they are usually not the approved service station for the liferaft itself. Liferaft servicing requires specialized equipment, controlled environments, and certification unique to lifesaving appliance maintenance stations, not standard shipyard facilities. * **B) They do not need any maintenance:** This is dangerously incorrect. Liferafts absolutely require regular, certified maintenance to ensure the integrity of the container, proper operation of the hydrostatic release unit (if applicable), and functionality/shelf-life of the contents. * **D) Have your crew check them annually:** Crew members are responsible for visual inspections and mandatory monthly/weekly checks of the liferaft’s condition, security, and accessibility (perishing of lashing, pressure gauge check, etc.). However, they are legally and technically unqualified to perform the mandated annual internal servicing, repacking, and testing required for certification. This annual service must be done by approved experts.
