50 personsCapacity

This Survitec 50-person open reversible inflatable liferaft is a SOLAS A rated survival craft supplied in a high-speed craft (HSC) pack. Being open reversible, it floats and can be used with either side up, and it is stowed in a container on deck and launched by throwing overboard or using a float-free arrangement. It is listed with SOLAS A and IMO type approval and provides buoyant refuge for 50 people after abandoning ship.

Service

Service notes.

What our service work and the manufacturer documentation say about keeping this model running.

Liferafts must be serviced at an approved service station at the required intervals, including inflation test, pressure holding check and renewal of the equipment pack. Surveyors check stowage and securing arrangements, hydrostatic release unit validity, markings, painter attachment and the certificate of service.

Inspection

Common failures & inspection points

Inspection

Inspector Detail

Common issues

  • Canister/valise UV and salt degradation over years of exposed davit or deck stowage
  • Hydrostatic release unit (HRU) reaching its marked expiry/service date without renewal
  • Painter line chafe or incorrect securing to the weak link/HRU
  • CO2 inflation cylinder corrosion or under-charge, typically found only at annual service
  • Raft fabric chafe/wear at cradle or davit contact points
  • Missing or expired items in the survival equipment pack found at service

Inspection checklist

  • Check the HRU model/serial and expiry date against its own marked service life
  • Inspect the canister/valise for cracking, corrosion, or seal damage
  • Verify the painter line is correctly rove and secured through an approved weak link
  • Check the cradle/stowage securing arrangement and both manual and hydrostatic release function
  • Confirm the last approved service station stamp and next-due date on the container
  • For the HSC pack, verify davit-launch attachment points and rapid-deployment release gear are free and correctly rigged
  • Check the raft is stowed clear of any obstruction to allow a fully float-free/inflated launch

Service intervals

Annual service at an approved liferaft service stationmandatory per SOLAS, typically every 12 months, or per any flag state extension allowance
Hydrostatic release unit renewalper the HRU's own marked service life, commonly around 2 years for hydrostatic-type units - always check the fitted unit's marking, do not assume
CO2 cylinder weighing/inspectionat each annual service

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

Critical spares

  • Hydrostatic release unit (correct approved type for a 50-person HSC-pack raft)
  • Approved weak link for the painter
  • Replacement CO2 inflation cylinder (service-station supplied and fitted only)

Safety

  • Sudden inflation hazard - the CO2 cylinder and inflation system must only be handled by an approved service station, never opened onboard
  • An incorrectly installed HRU is a life-safety single point of failure that can prevent free-float release
  • Confirm the davit/launch appliance SWL matches the fully equipped raft weight for HSC deployment
  • Painter line under load during launch - crush/entanglement hazard for crew handling deployment

Class survey

As a SOLAS life-saving appliance, this is subject to annual service by an approved station and to class/flag survey of the certificate and stowage arrangement. Class checks the service station report, HRU expiry, and davit/launch appliance condition rather than performing any internal inspection of the raft itself.

Estimated lifetime: Liferaft fabric and container service life is normally stated in years rather than running hours - typically a 10-12 year design life before class/maker review of further service, subject to condition confirmed at each annual inspection.

Replacement Parts

Spare parts notes

Keep spare hydrostatic release units and spare lashings or securing parts as permitted. Raft contents and gas cylinders are handled by the approved service station. Maintain the service records and labels for each raft.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
