The payload can be transferred between two relatively movable stations, for example two ships (10,12) using a winch having an inhaul winch (30) and an outhaul winch (32). The barrel of the outhaul winch is driven by an outhaul motor through a toroue converter so that the outhaul winch provides pull on the trolley (16) regardless of the sense of rotation of the outhaul winch barrel. A control is used to control the speed of the inhaul winch barrel either to retrieve cable or to pay out cable. Thus, the speed of the trolley (16) is controlled by the speed at which the inhaul winch barrel is driven. The outhaul winch either can be at the same station as the inhaul winch or can be at the opposite station to the inhaul winch. |
