Abstract
A method and apparatus is provided for dissipating the energy of random dynamic forces exerted against a pier. The dynamic forces are received by a bumper connected to the side of a pier. The normal components of the forces exerted against the bumper are cushioned and the energy of these forces dissipated by means of reactive forces developed incident to compression of a plurality of compressible, self-restoring cushions connecting and extending orthogonally between the bumper and the pier. Lateral displacement of the bumper relative to the pier in response to components of the dynamic forces acting parallel to the bumper is rigidly restrained by restraining members connecting the bumper and the pier. Once the normal components of the dynamic forces are dissipated, the cushions restore themselves to uncompressed, fully extended conditions and the fender is prepared to receive subsequent loads.
