“Oyster” is the name of a device purposed to harness nearshore wave power. The Oyster has been developed by Queen’s University Belfast and Aquamarine Power Limited. They are taking part in a new five-year research partnership that will develop this kind power wave power converters.
The Oyster is basically a steel oscillating wave surge converter. It is fitted with double-direction water pistons, deployed near-shore at depths of 10 to 12m. As waves activate it, the pump delivers high pressure water through a sub-sea pipeline straight to the shore, as seen in the picture above.
The most complex part of the system is onshore, in the electrical power generating system, using conventional standard hydroelectric generators.
The first Oyster will be launched launched this summer at the European Marine Energy Centre off the coast of Orkney. It will provide important data to the researchers as to whether it’s viable and survives the sea conditions.
