Inspection

Inspector Detail

Common issues

  • Skid/ramp release mechanism seizing from corrosion or paint build-up
  • Freefall release hook misalignment or failure to reset cleanly after a dry test
  • GFK hull gelcoat cracking, particularly at the bow area from repeated free-fall impact
  • Engine starting failure after prolonged standby
  • Harness/seatbelt degradation from UV exposure and wear
  • Painter line and secondary retrieval line chafe
  • Ramp/skid lubrication breakdown causing an uneven or delayed launch

Inspection checklist

  • Visual hull inspection, including the bow impact area, for cracks or delamination
  • Freefall release hook dry function test
  • 5-year on-load release gear overhaul/load test
  • Skid and ramp condition and lubrication check
  • Harness and seat condition check for all occupant positions
  • Engine start and cooling system test
  • Battery and electrical system check
  • Painter and secondary means of launching inspection
  • Hydrostatic release unit service-date check, if fitted
  • Cradle securing and lashings condition check

Service intervals

On-load release gear overhaul5 years, class-witnessed per SOLAS/LSA Code
Full davit-free-fall system thorough examination12 months
Engine servicingper running hours or annually
Skid/ramp lubricationper maker's schedule, commonly every 6-12 months or before each drill

Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.

Typical wear limits

Hook pin/bushing wearrenew per the maker's tolerance stated in the O&M manual
Harness webbingrenew on visible UV degradation, cuts, or fraying, or once the maker's rated service life is reached - confirm against the harness label/manual

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

  • Freefall release hook assembly components (name only - confirm exact part with maker)
  • Harness sets
  • Engine starter battery
  • Ramp/skid lubricant (maker-specified type)
  • Hydrostatic release unit, if fitted

Safety

  • Free-fall launch carries inherent occupant-injury risk from impact deceleration
  • Accidental operation of the on-load release hook during maintenance
  • Fall-from-height risk during boarding and drills
  • Engine exhaust build-up during confined start tests

Class survey

Freefall lifeboats are under LSA Continuous Survey: annual thorough examination plus the 5-yearly on-load release gear overhaul; class pays particular attention to release-hook maintenance history given the industry's known incident record with freefall systems.

With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days.
