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.
| Weekly/monthly operational test | per the SOLAS LSA maintenance schedule and manufacturer instructions |
|---|---|
| Wire rope inspection | at each davit inspection; renewal typically every 4-5 years or condition-based - confirm against maker/class requirement |
| Gearbox oil change | per maker manual, typically annually or per running hours |
| Annual thorough examination | annually, by a competent person per the SOLAS LSA Code |
| Winch/davit dynamic load test | 5-yearly at proof load per SOLAS/flag-state requirement - confirm exact interval and load with class |
Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.
| Wire rope broken wires | discard criteria are set by the rope's own standard and the maker manual (commonly a set number of broken wires within a given lay length) - confirm the exact figure there rather than applying a single generic number |
|---|---|
| Brake lining wear | renew at the maker's minimum thickness or wear indicator - condition-based, no safe generic figure to quote |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Lifeboat/rescue boat davits and winches are SOLAS LSA Code items requiring annual thorough examination by a competent person and 5-yearly dynamic load testing at proof load, per SOLAS III and the manufacturer's maintenance manual. Class/flag state will want records of the annual service, load test certificates, and wire rope renewal history; missing current load test certification is a common detention item.
Estimated lifetime: Davit winches of this type are typically kept in service for the life of the vessel, with periodic overhaul and wire rope renewal governed by a fixed calendar/condition schedule rather than a running-hour count.
