SEATURNS

The SEATURNS solution is the result of a benchmarking of existing WEC (wave energy converter) technologies with the various obstacles that prevent their commercial development. The chosen solution is a compact, small, simple solution that uses the free water ballast technique.

The oscillating water pendulum, similar to an oscillating water column, induces compression / depression cycles in two chambers filled with air. The pressure differential between the two chambers generates a flow of air that drives a turbine. The steel float consists of two coaxial cylinders, of rigid bulkheads and a separate bulkhead, all soldered to each other, the only moving element being the free water ballast, consisting of sea water collected on the spot (80 % of the mass of the float).
