Torque Control

-19 Abstract Title: Torque control for wave energy converter A power take-off arrangement for a wave energy converter is described. The arrangement has a gearbox having a first shaft (20) connected to the wave energy 5 converter (1) which is adapted to receive, in use, rotational motion from the wave energy converter. The gearbox has a second shaft connecting the annulus gear (31) to the generator shaft (36). A third shaft (38) is connected to one or more means (39) of applying torque to it. Torque applied by the one or more means (39) may be varied in operation so as to alter the relative rotational velocities and accelerations of 10 the second and third shafts in response to any given rotational velocity or acceleration of the first shaft.
