Set of 4 mooring winches designed, fabricated and supplied for the Hydro Dive DSV “HD Commander”.  Each winch carries 1,500m of 28mm SWR and has a bare drum pull capacity of 30 tonnes.  The winches are driven via a 110 kNm final drive planetary gearbox mounted inside the winch drum to minimise the space requirements.   For power efficiency the gearboxes are driven by variable speed axial piston motor to allow high speed operation on low load and low speed operation on high load . The two bow winches were fitted with automatic spooling- [Top Right]
