Zodiac USCG/SOLAS 'A' Liferaft 8-Person, Low Profile Container
Survitec Group Zodiac USCG/SOLAS 'A' Liferaft 8-Person, Low Profile Container — Commercial vessel emergency evacuation.
Inspector Detail
▸
Common issues
- Painter line securing point corrosion or improper lashing to the deployment cradle
- Hydrostatic release unit (HRU) past its service life or incorrectly mounted, preventing free-float release
- Container seal band deterioration allowing moisture ingress
- CO2/N2 inflation cylinder valve corrosion or under-pressure found only at annual service
- Cradle securing straps over-tightened or seized, delaying manual launch
- UV degradation of the container GRP shell on exposed weather decks
- Retro-reflective tape and light bracket missing or damaged after re-fit
Inspection checklist
- Confirm annual service due date and last approved service station stamp on the container
- Check HRU manufacture/expiry date (typically 2-year service life) and correct weak-link attachment
- Verify painter line is free to run and secured to the ship, not seized to the cradle
- Check cradle securing arrangement releases without tools under load
- Inspect container for cracks, distortion, and integrity of the sealing band
- Confirm container is stowed with correct float-free clearance and no obstruction above
- Check that the SOLAS pack contents list and last repack date match the service certificate
- Verify raft light bracket and float-free link are fitted and undamaged
Service intervals
| Annual service at approved liferaft service station | 12 months (extension up to 17 months only where permitted by flag/class) |
| Hydrostatic release unit (HRU) replacement | per manufacturer service life, typically 2 years |
| Full raft condition/pressure test | at each approved service, per manufacturer schedule |
| Container and cradle visual inspection by crew | monthly |
Critical spares
- Hydrostatic release unit (weak link + HRU assembly, correct model for this container type)
- Painter line (approved length/breaking strain for this raft size)
- Container sealing/banding tape
- Raft light and battery (service-station supplied)
- Cradle securing strap/lashing set
Safety
- CO2/N2 cylinder is pressurised; do not attempt to open or service the container onboard
- HRU weak link must match the vessel's displacement class - wrong link can prevent release or cause premature release
- Never stow cargo or lines over the raft that would obstruct float-free operation
- Manual launch under load can cause crush injury if the cradle release binds
Class survey
Liferafts are surveyed against the valid approved-service-station certificate; class checks the certificate date, HRU expiry, and that container/cradle marking matches the ship's fire and safety plan. A raft found overdue for annual service is normally logged as an outstanding condition of class.
