Hydraulic mooring cable anchor, system and method

摘要

The hydraulic mooring cable fixture provides a hydraulic cylinder-piston combination (20) for controlling the force exerted on the mooring cable between one end of the ship and the mooring point. The overpressure prevention portion 26 allows the hydraulic fluid to pass from the hydraulic cylinder 20 to the reservoir 260 when the in-cylinder pressure exceeds the threshold value, and when the pressure is lowered, the overpressure prevention portion 26 conveys the hydraulic fluid. An auxiliary reservoir (24) with a more abrupt pressure response than the main reservoir (260) is connected in parallel with the main reservoir. The auxiliary reservoir may be connected to and / or separated from the cylinder under the control of a further mooring device at the other end of the sensor or vessel to reduce movement of the vessel in the play. The pressure from the auxiliary reservoir can also be used to drive the generator.
