Remotely operated underwater vehicle
InactiveUS20100212574A1Solve the lack of spaceMore forceCommunication meansUnderwater vesselsWireless transceiverTransceiver
A system for communicating with a remotely operated underwater vehicle (ROV) includes a winged ROV coupled to a surface buoy by a tether. A controller on a support ship is coupled to the tether and the control signals are then transmitted through the tether to the ROV. Feedback and sensor signals are transmitted from the ROV through the wireless transceivers to the controller. The wings of the ROV produce negative lift which is greater than the buoyant force of the ROV and the vertical tension forces on the tether.

ActiveCN109070976AFast and reliable tensioningPrevent pull outWinding mechanismsTetherHydraulic cylinderControl system
Anchor winches (10) are used to lower and haul in anchors together with the anchor chains thereof. The anchor winches (10) have a drive, by means of which at least the hauling in of the anchor together with the anchor chain occurs in a motorized manner. Under unfavorable conditions, the power of the drive may be insufficient to haul in the anchor. Then there is the risk that the anchor chain is pulled from the anchor winch (10), which in the worst case leads to the loss of the anchor. The aim of the invention is to avoid the described disadvantages. This aim is achieved by an anchor winch (10), the band brake (15) of which can be manually actuated according to a first actuation mode and, in an emergency, can be automatically actuated by means of a second actuation mode, for example by means of a hydraulic cylinder (28) that can be actuated by a control system. The hydraulic cylinder (28) operates the actuating device (21) of the band brake (15) in an emergency in order to thus virtually initiate an "emergency stop", which eliminates the risk of the anchor chain being unintentionally pulled from the anchor winch (10) under high loads.
