Yacht/Boat DNV-Approved (Review) · Yacht & Boat Equipment
Optimus 575 by Ocean tec d.o.o. is a deck capstan intended for mooring and line-handling duties. The vertical warping head allows a rope to be surged, heaved or controlled while the operator manages the number of turns on the drum. The unit is normally mounted on an exposed deck with the drive, gearbox and associated electrical or hydraulic components protected below or within the deck machinery arrangement. Reliable operation depends on sound deck foundations, correct rope lead, effective braking or clutch functions where fitted, and protection against seawater ingress. Compared with neighboring capstan sizes, the main differences are normally rated pull, speed, drum geometry and drive package. Use the maker documentation and vessel deck-machinery drawings to confirm the installed execution and permissible operating limits.
What our service work and the manufacturer documentation say about keeping this model running.
Inspect the warping head, shaft, deck fastenings, guards, controls and visible corrosion routinely under the deck-machinery PMS. Check gearbox lubricant condition and leakage, and service bearings and lubrication points in accordance with the maker instructions. Function-test local and remote controls, emergency stop and brake/clutch functions where fitted. Inspect electrical insulation and water ingress or hydraulic hoses, fittings and oil cleanliness according to drive type. Class survey attention may include structural attachment, safe operation, braking/holding function where relevant and condition of associated controls; use manufacturer documentation for exact limits and intervals.
| Gearbox oil check | annually |
|---|---|
| Gearbox oil change | every 2-3 years or per maker's manual, duty dependent |
| Grease deck bearings/drum shaft | every 3-6 months |
| Electrical connection/corrosion check | annually |
Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.
This unit carries an RCD (Recreational Craft Directive) certificate, indicating small/leisure-craft equipment rather than a SOLAS class item. Where a class or flag regime does apply, surveyor interest is typically limited to secure mounting and safe operation rather than a dedicated machinery survey item.
Estimated lifetime: Small-craft capstans/mooring winches of this class typically give 10-15 years of service with routine gearbox and seal maintenance - confirm against maker's manual
Keep seal and gasket kits, control switches or contactors/solenoids appropriate to the drive type, brake or clutch wear parts where fitted, and common bearings if approved for onboard renewal. For hydraulic units, carry critical hose/seal items used in the installed circuit; for electric units, keep the relevant overload/control components. Confirm gearbox and drive spares against the serial number because different executions can share the same series name.
