Inspector Detail
▸
Common issues
- CO2 cylinder pressure loss from a slow leak at the valve or thread connection
- Hydrostatic release unit (HRU) reaching its expiry date without being renewed
- Container/valise UV and weather degradation leading to cracking
- Painter line incorrectly rigged or chafed
- Inflation valve leakage found only at service
- Canopy or buoyancy tube fabric degradation from years of UV exposure on deck
- Survival kit contents (flares, rations, first aid) expiring unnoticed between services
Inspection checklist
- Check the container/cradle for damage and secure stowage
- Check securing straps and lashings
- Check the hydrostatic release unit's expiry date and correct fitting/orientation
- Check the last-service date on the container label/certificate
- Check the painter line is correctly attached to the ship and not fouled
- Confirm the launch area is clear of obstructions
- Check the davit and cradle release mechanism where the raft is davit-launched
- Cross-check raft capacity and type against the ship's SOLAS equipment list
Service intervals
| Annual service | at an approved liferaft service station, per SOLAS requirements |
| Hydrostatic release unit renewal | per the unit's marked expiry, commonly every 2 years - confirm against the fitted HRU's label |
| Extended service scheme (partial disassembly) | where approved by the flag administration/manufacturer, typically introduced around 10-12 years of age - confirm against the specific approval |
Critical spares
- Spare hydrostatic release unit (correct type and in-date)
- Painter line and lashings of the correct rating
- Spare container securing strap set
Safety
- The CO2 cylinder is a pressure vessel - never attempt to open or service the container aboard; use only an approved service station
- Hydrostatic release units contain a water-triggered release element - handle and store per the expiry date, never tamper with it
- Container weight is substantial - use correct manual handling technique or lifting gear during drills to avoid injury
- Keep hands and body clear of the painter line and container during launch drills in case of unexpected inflation
Class survey
Surveyors check the service certificate is current, the raft's capacity and type match the ship's SOLAS equipment list, the HRU is in date and correctly fitted, stowage and painter rigging are correct, and for davit-launched rafts that the launching appliance operates correctly
