A wave energy converter (10) or the point absorber or heaving-buoy type comprises a buoyant body (11), an acceleration tube (14) dependent from and attached to the buoyant body (11), a working piston (17) reciprocable in the acceleration tube (14), and an energy-absorbing device (S) operatively connected with the working piston (17). A fluid compartment (21) provided in the acceleration tube (14) can hold an added mass which consists of water taken from the body of water in which the wave energy converter operates and is trapped in the compartment (21) and fills it to a desired degree. The added mass influences the resonant frequency of the wave energy converter. |
