Abstract
A mass displacement wave energy conversion system comprising a platform mounted on a stable base to protect the system against the interference of wave motion. Beneath the platform are mounted a plurality of pumps operated by a buoyancy vessel and a ballast mass. The buoyancy vessel and ballast mass are attached to a sleeve pump on a shaft supported in the ocean floor by an anchored footing with the other end being secured to the system platform. The pumps are connected to a manifold so they accumulate a constant volume and pressure even though each pump operates separately. The ballast mass buoyancy vessel and pump are constructed to slide on the mounting shafts to produce water at a constant pressure and volume at the manifolds that can be interconnected to drive a variety of devices.
