摘要： A hydraulic reactor system for minimizing mooring forces of a vessel attached to an offshore structure, by means of a ramp which enables access between the two, comprising a structural frame provided with a hydraulic piston utilizing a one-way pressure relief valve which allows inward movement with minimal resistance. Conversely, the outward movement of the hydraulic piston provides considerable resistance. The device is connected to, or involved in, a ramp structure allowing an extension or reduction in length of the radius of the geometric configuration as it pivots vertically when attached to a vessel on its outboard end. The upward movement energizes the system by compressive action with minimal resistance, while the downward movement produces considerable resistance to outboard movement of the vessel. This vertical movement of the vessel caused by the waves produces reaction forces in a direction against those elements such as wind, waves and current that would tend to cause horizontal movement of the vessel. It is this process of gently nudging the boat in an up weather direction, with each of its downward movements, that causes an inertial reaction that overcomes the forces of the environment with minimal effort. The device can be pivotally attached to a mooring point, known as a "king post", allowing the device and attached ramp/vessel to "weathervane" about the "king post" responsive to changes in direction of the mooring forces.
