15t heavy-lift winch
A 15-tonne SWL hydraulic heavy-lift winch, engineered to DNV offshore-lifting standard for deep deployment, designed and detailed for manufacture.

A compact, high-capacity hydraulic winch for deep heavy-lift deployment and recovery offshore. Rated at 15 tonnes SWL on the working layer with around 700 m of wire deployed, it is built around a piston-motor-and-planetary-gearbox drive on a Lebus-grooved drum and designed to the recognised offshore lifting-appliance standard. It is dimensioned to sit compactly at the base of a derrick and feed wire up to head sheaves, and can be deployed as a pair where a heavier lift or a spooling arrangement calls for it.
What we engineer
- Hydraulic drive – a piston hydraulic motor through a planetary gearbox, sized to the line pull and the available hydraulic supply, with proportional control via the spool valve.
- Grooved drum & rope – a Lebus-grooved drum sized to the wire’s bend-radius and safe-turn requirements, running a compacted, rotation-resistant heavy-lift rope; the fleet angle is engineered so the winch can run without a spooler, with accommodation designed in for future spooling gear.
- DNV-compliant braking and load-holding – fail-safe braking and load-holding engineered to the offshore lifting-appliance standard, so the load is held safely on loss of power.
- Compact, derrick-base envelope – a base-frame winch dimensioned to fit at the foot of a derrick and feed the head sheaves, with parts commonality designed in to standardise spares across a fleet.
- Pairable for heavier duty – two units can work together, including arrangements where one drum spools the other.
| Parameter | Design basis |
|---|---|
| SWL | 15 t on the working layer at depth (layer-dependent; higher on the first layer) |
| Deployment | ~700 m wire deployed; drum capacity sized well beyond, for pairing/spooling |
| Line speed | ~40 m/min (mid-drum), subject to hydraulic supply |
| Wire | Compacted, rotation-resistant heavy-lift rope (~28 mm class), Lebus-grooved drum |
| Drive | Piston hydraulic motor + planetary gearbox; proportional spool-valve control |
| Braking | Fail-safe braking & load-holding to DNV offshore lifting-appliance standard |
| Standards | DNVGL-ST-0378 (offshore & platform lifting appliances); wire/drum to DNV-OS-D101 / E101 |
| Maturity | Designed and detailed for manufacture (DNV-standard design + manufacturing drawing pack) |
Ratings are a design basis confirmed to the duty at enquiry; exact figures and the drive/HPU sizing are set per project. This is a straight heavy-lift winch, for constant-tension or heave-compensated duties see our active constant-tension and active heave compensation winches.
