Designed to ensure rapid and safe deployment in emergency situations, the 25 man throw-over SOLAS A and B pack inflatable liferaft, packed in cylindrical container / Trademarks: SURVITEC, ENDURA, CREWSAVER, ELLIOT, DSB, SURVITECZODIAC, RFD, SSP, BRUDE, RFD TOYO is a critical piece of crew evacuation equipment. This liferaft is certified to carry 25 persons and meets the stringent safety standards set by SOLAS, ensuring reliable performance in maritime emergencies. The hydrostatic release unit (HRU) is a crucial component, but it must be replaced at the manufacturer's recommended interval, typically every two years, to prevent critical safety failures. Common issues include pressure loss in the CO2 bottle due to corrosion or aging, fabric degradation from UV exposure, and corrosion or blockage of the painter line. Additionally, survival equipment such as flares, water, and rations must be regularly checked and replaced. Annual servicing at an approved SURVITEC GROUP LIMITED service station is mandatory, and it is essential to keep a spare HRU on board. The 25 man throw-over SOLAS A and B pack inflatable liferaft, packed in cylindrical container / Trademarks: SURVITEC, ENDURA, CREWSAVER, ELLIOT, DSB, SURVITECZODIAC, RFD, SSP, BRUDE, RFD TOYO requires recertification or replacement every five years to ensure ongoing compliance with SOLAS/MSC.1/Circ.1328 regulations.

Inspection

Common failures & inspection points

Inspection

Inspector Detail

Common issues

  • Hydrostatic release unit (HRU) reaching its expiry date without replacement
  • Painter line chafe or degradation
  • Container cradle and retaining band corrosion
  • Quick-release/lashing mechanism seizing from corrosion
  • Canister seal deterioration allowing water ingress before service

Inspection checklist

  • Container external condition - no dents, corrosion or visible damage
  • HRU expiry date check
  • Cradle and quick-release/lashing condition
  • Painter line attachment and routing check
  • Service due date label check
  • Launching area clear of obstructions for throw-over deployment

Service intervals

Annual service at an approved shore station12 months, per SOLAS requirement
Hydrostatic release unit replacementevery 2 years, standard HRU service life
Full raft condition/inflation test at the service stationat each annual service per SOLAS
Painter line/lashing inspectionat each annual service and at routine deck rounds

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

Typical wear limits

Painter line conditionrenew if chafed, cut or below the SOLAS LSA Code strength requirement for the raft's capacity - confirm against Survitec's service manual

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

Critical spares

  • Hydrostatic release unit (HRU)
  • Painter line
  • Cradle lashings/retaining band

Safety

  • The HRU is a life-critical item - an expired or incorrectly fitted HRU can prevent automatic float-free release in a sinking
  • Liferaft servicing and repacking must only be carried out by an approved service station - never open or repack the container onboard
  • The inflation cylinder is under pressure - mishandling during service risks injury
  • Throw-over launch needs clear deck space and trained crew to avoid injury during deployment

Class survey

Checked at the annual safety equipment survey - class verifies the service due date, HRU expiry, correct capacity/type for the vessel's LSA arrangement, and a valid service station certificate; an overdue liferaft service is a common detention-level deficiency.

Estimated lifetime: Not applicable in running hours - SOLAS liferafts have a service life on the order of 12-17 years subject to passing each annual service, after which the maker or class may require retirement or major refurbishment - confirm against Survitec and the flag state requirement.
