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.
| Annual service/thorough examination | annually per LSA Code/SOLAS requirements |
|---|---|
| 5-yearly winch overhaul and load test | davit winch to be overhauled and tested to proof load at 5-year intervals per SOLAS III requirements |
| On-load release gear overhaul | per SOLAS/maker requirement, typically every 5 years |
| Wire fall replacement | condition-based per inspection findings, commonly renewed within 5 years or sooner if damage/corrosion is found |
| Hydraulic oil change | per maker's interval, typically annually |
Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.
| Wire fall diameter reduction | discard per the class/rope-maker's criteria, commonly around 10% reduction from nominal - confirm against the wire's certificate |
|---|---|
| Brake lining thickness | renew before reaching the maker's minimum mark |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
LSA Code annual thorough examination and SOLAS III 5-yearly load test/overhaul of the winch and release gear are mandatory documentation items; class will want to see dated test records, wire fall certificates and evidence the on-load release gear has been maintained per the maker's instructions, not just visually checked.
Estimated lifetime: Not expressed in running hours; the davit structure is typically designed for 20-25 years of service subject to annual survey, while wire falls, brake linings and seals are condition-based consumables
