Abstract: Apparatus for absorbing the shock of a relatively large, movable load, such as a ship striking a dock or the like. The apparatus includes a loadreceiving buffer comprised of a fluid piston and cylinder assembly, the buffer being in fluid communication with a hydro-pneumatic accumulator through first and second fluid flow paths. When a force is exerted on the buffer, fluid flows therefrom through one of said paths and part of the kinetic energy is stored in the accumulator with the greater portion dissipated as heat. The buffer is restored to its initial position by fluid flow from the accumulator to the buffer along the second path. The system operates to assure that the buffer will exert a substantially constant reactive force regardless of displacement to thereby assure dissipation of the kinetic energy with an efficiency approaching 100 percent and with a minimum storage of potential energy.
