Inspector Detail
▸
Common issues
- Container/valise weathering and seal degradation affecting weatherproofing
- Painter line chafe or corrosion at the hydrostatic release unit connection
- Hydrostatic release unit reaching its expiry date unnoticed
- CO2 cylinder corrosion or under-charge affecting inflation
- Canopy/buoyancy chamber fabric degradation from UV exposure
- Survival equipment pack contents (flares, food, water) passing expiry unnoticed
Inspection checklist
- Monthly visual inspection of container, cradle and hydrostatic release securing
- Annual service by an approved liferaft service station (mandatory for SOLAS A)
- CO2 cylinder weight/pressure check at annual service
- Hydrostatic release unit expiry date check
- Painter line and weak link condition check
- Survival equipment pack expiry date check (pyrotechnics, food, water)
- Cradle/securing arrangement corrosion check
Service intervals
| Annual service at approved service station | 12 months (SOLAS mandatory) |
| Hydrostatic release unit replacement | per marked expiry, commonly every 2 years |
| Pyrotechnic signals in equipment pack | replace per expiry, typically every 3-4 years |
| Deeper inspection/component renewal | per the maker's service bulletin schedule, e.g. every 5 years |
Critical spares
- Hydrostatic release unit (approved matching type)
- CO2 inflation cylinder
- Painter line/weak link
- SOLAS A survival equipment pack
- Inflation/relief valve service kit
Safety
- CO2 cylinder is under pressure - only trained service station personnel should handle inflation system components
- An expired hydrostatic release unit can prevent automatic float-free release in an emergency
- Container must be stowed to allow free-float release, never lashed in a way that could obstruct it
Class survey
A valid annual service certificate from an approved service station is required for compliance; class/flag surveys check the service due date, hydrostatic release unit expiry, and general condition of stowage and cradle arrangement.
