Abstract
A pier cushioning system is disclosed having a contact surface, sliding elements and hydraulic cylinders and apparatus to determine the mass and velocity of a docking vessel and to respond with the necessary counterforce to assist in the docking of the vessel. The mass and velocity determining capabilities utilize a flow and pressure transducer in combination with either a microprocessor or analog electronic circuit to perform the necessary calculations and thus adjust the flow of hydraulic fluid within the hydraulic cylinder in accordance with the force exerted by the docking vessel.
