Inspector Detail
▸
Common issues
- Container/valise damage from UV exposure, corrosion, or impact during handling
- Hydrostatic release unit (HRU) expiry or malfunction
- CO2/gas inflation cylinder corrosion or under-charge
- Painter line chafing or incorrect securing
- Rubberised fabric degradation or delamination over service life
- Missing or expired survival equipment pack contents found at service
Inspection checklist
- Check container/cradle for physical damage, corrosion, and secure mounting
- Verify hydrostatic release unit (HRU) expiry date and correct installation
- Check painter line attachment and weak link condition
- Confirm a valid, in-date service/inspection sticker from an approved service station
- Verify float-free arrangement and cradle release mechanism function
- Check that the gas cylinder pressure/weight record from the last approved service is current
- Inspect for external damage, corrosion, or paint overspray on the container
- Confirm the SOLAS-B pack contents list matches the certificate
Service intervals
| Approved service station service | annually, as required by SOLAS |
| Hydrostatic release unit renewal | typically every 2 years or per the manufacturer's expiry marking |
| First overhaul | commonly required at 5 years from commissioning, then annually, per flag/class requirements |
| Full inflation/pressure test | performed at the approved service station per its schedule, not shipboard |
Critical spares
- Hydrostatic release unit (HRU) - replacement within expiry date
- Painter line and weak link assembly
- Container securing straps/cradle hardware
Safety
- Never open or service the pressurised container onboard - the inflation system is a pressure hazard
- Incorrect HRU installation can prevent float-free deployment in an emergency
- Painter line must be correctly secured - incorrect rigging can prevent deployment or cause the raft to be dragged under
- Container weight during handling and launching - manual handling injury risk
Class survey
Surveys check for a valid, in-date service certificate from an approved service station, correct HRU expiry, correct stowage and float-free arrangement, and that raft capacity matches the vessel's safety equipment certificate.
