    Abstract: A fender for fending a ship from a mooring wall comprises a hydraulic cylinder and piston assembly arranged so that compression of the fender is translated into a force to move the piston in the cylinder. Valves couple the hydraulic cylinder to reservoir that is at least partially filled with gas. An overpressure valve allows hydraulic liquid to flow from the cylinder to the reservoir when the fender compression force exceeds a threshold, allowing the fender to be compressed. When the force drops away, a return valve allows hydraulic liquid to return to the cylinder, causing the piston to move to expand fender, following movement of the ship away from the fender. In this way oscillating motion is reduced. A plurality of such fenders may be combined with mooring cable holding devices with a similar mechanism that pays out cable when the movement of the ship from the mooring wall cause the force on the mooring cable to grow. Energy generated from such forces may be used to reduce movement of the ship.

    Abstract: A tri-adaptive apparatus is disclosed and configured for functioning as a dynamic force isolation and dampening metamaterial that reduces the transmission of dynamic forces between a dynamic force source and an object. In at least one embodiment, the apparatus provides at least one cell unit that provides a pair of opposing first and second cell plates, between which is positioned at least one spring, restrainer and dashpot. An outer surface of the first cell plate is positioned in contact with the dynamic force source. An outer surface of the second cell plate is positioned in contact with the object. The at least one spring, restrainer and dashpot are configured for transferring dynamic force energy mutually between one another while deforming mechanically in response to the dynamic forces transmitted by the dynamic force source.
