| Brake band lining inspection | every 3-6 months, or per maker's manual |
|---|---|
| Gearbox oil sample/analysis | annually |
| Gearbox oil change | typically 1-2 years depending on duty cycle - confirm against maker's manual |
| Hydraulic filter change | 6-12 months or per differential pressure indicator |
| Wildcat/chain gauge check | annually or at each dry-docking |
| Brake holding capacity test | annually - typical class/statutory requirement, confirm against certificate |
Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.
| Wildcat tooth wear | manufacturer-specific limit before chain slip begins - check against the class-approved chain gauge, no universal figure |
|---|---|
| Brake band lining thickness | renew before base material contacts the drum, follow maker's minimum thickness |
| Gear backlash | bauart-typical 0.1-0.3 mm for this size class - confirm against maker's manual |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Anchor windlass and mooring winch equipment typically falls under Continuous Survey Machinery or an annual survey item depending on class. Surveyors generally want to see brake holding-capacity test records, chain gauge measurements, and evidence of periodic function testing of remote/emergency controls, plus repair records for any load-bearing component.
Estimated lifetime: Structural/mechanical service life of 20-25 years is typical for windlass/mooring winch equipment of this size and duty, with hydraulic components usually renewed every 5-10 years depending on duty cycle - confirm against maker's manual
