| Hydraulic oil and filter change | annually or per manufacturer schedule |
|---|---|
| Gear oil change (geared sections, if fitted) | annually |
| Brake band inspection | annually, renewal condition-based |
| Cable lifter wear check against chain | annually, per class requirement for anchor gear |
| Grease bearings and pivot points | per PMS, commonly every 1-3 months |
Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.
| Cable lifter pocket wear against chain | condemn per the chain diameter-loss criteria in the applicable class rules (a chain link diameter reduction of roughly 12% is a common condemning guide across class societies) rather than a windlass-specific figure - confirm against Nippon Pusnes documentation and the vessel's class rules |
|---|
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Anchor and windlass gear is surveyed under class deck machinery rules, including a brake holding test, cable lifter/chain wear check, and confirmation that anchor and chain markings match the vessel's equipment certificate.
Estimated lifetime: Anchor windlasses are normally rated by design life in years (typically 20-25 years of vessel service) rather than running hours, given the intermittent duty cycle; wear parts (brake lining, cable lifter, seals) are renewed on condition.
