Service

Service notes.

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

Weekly engine test run (min. 5 min). Release hook servicing annually by an approved service provider (SOLAS MSC.402(96)). GRP hull inspection at docking. Five-year thorough examination.

Inspection

Inspector Detail

Common issues

  • Wire fall wear or corrosion, particularly at drum and sheave contact points
  • Docking head misalignment leaving pendulum motion not fully suppressed
  • Electric drive motor or hydraulic pump faults limiting available drive modes
  • Brake system drift under load
  • Limit switch or overrun protection failures
  • Manual back-up drive (handwheel/crank) seized from lack of use

Inspection checklist

  • Visual inspection of wire falls, drum, and sheaves
  • Test all available drive modes - electric, hydraulic, and manual - in turn
  • Check docking head function and alignment against the hull
  • Test brake holding and controlled lowering speed
  • Test on-load release gear per the maker's procedure
  • Check limit switches and overspeed/overrun protection
  • Verify emergency stop and local/remote control stations

Service intervals

Weekly operational testper SOLAS, davit and boat operated through range where practicable
Monthly inspectionvisual and functional per the LSA Code
Annual thorough examinationper SOLAS III/20 and the LSA Code by a competent person
On-load release gear overhaul and load testevery 5 years, per SOLAS III/20.11
Manual back-up drive exerciseat each monthly test, to prevent seizure

Typical wear limits

Wire fallreject per the LSA Code wire rope rejection criteria - condition-based, not a fixed number
Brake lininginspect for glazing and thickness per the maker's manual, no generic figure applies across davit sizes

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

Critical spares

  • Wire fall set
  • Brake linings/pads
  • Limit switch assemblies
  • On-load release gear components
  • Hydraulic pump or electric drive motor seal/brush set, as applicable

Safety

  • On-load release gear malfunction risk as with all davit systems - strict test procedure adherence required
  • Suspended load hazard during any test or maintenance
  • Multiple drive modes increase the risk of an un-isolated back-up drive engaging unexpectedly - confirm all drives isolated before working on the mechanism
  • Docking head pinch points

Class survey

As an IMO/SOLAS-approved launching appliance, subject to the same SOLAS III/20 and LSA Code inspection, annual thorough examination, and 5-yearly overhaul/load test regime as other lifeboat/raft davits; class specifically checks on-load release gear overhaul records.

Estimated lifetime: Davit structure is designed for the ship's service life with periodic overhaul; wire falls and on-load release gear are renewed on the condition/interval basis above rather than by running hours, given the intermittent duty cycle.
