An indirect hydraulic load hierarchical control system and method for a wave energy device includes a first hydraulic cylinder group, a second hydraulic cylinder group, a third hydraulic cylinder group, a high-pressure energy accumulator group, a pressure detection control module, a first hydraulic power generator set, a second hydraulic power generator set and a third hydraulic power generator set. A detection end of the pressure detection control module is used for acquiring an internal pressure of the high-pressure energy accumulator group, comparing the internal pressure with a preset pressure level, and respectively controlling the on-off of reversing valves and electromagnetic valves according to a comparison result. The present invention has the beneficial effects that all hydraulic loads can be automatically loaded or automatically unloaded, so that the wave energy device operates in a full load state or in an optimal energy conversion efficiency state.

A constant tension anchoring system mounted on a floating body in the ocean includes an anchor, an anchor chain, an anchor windlass, a towing cable, a load and a chain stopper. During the oscillatory motion of the waves, the constant tension anchoring system repeats the release and retraction so as to maintain a generally constant tension force and thereby ensure the safety of the anchoring system and the floating body.
