• Maintenance regime: SOLAS III Regulation 20.11
• Launching appliances: annual survey, dynamic winch brake test at max lowering speed with survival craft mass, 5-year test with 1.1× full load
• Release gear: annual survey, operational test, 5-year overhaul with 1.1× full load test
• Free-fall release systems: operational test by free-fall launch or non-launch test per maintenance requirements
• Pre-drill check: maintenance per manuals, report abnormal wear/tear/corrosion
• Secondary lowering means: winch and falls, maintained per SOLAS III/20.11, no dynamic brake test per IACS SC244
• Abandon ship drills: every 3 months, boarding, securing, simulated launch (no hook release)
• 6-month drills: free-fall launch with operating crew or simulated launch per MSC.1/Circ.1206
• Monthly drills: embarkation, seating, safety belts, launching actions per manufacturer’s instructions
• FPD requirement: in place unless off-load hook or approved exemption
