Identification of the WEC concept and starting of the conceptual design was made in 2005. Following the identification of the WEC, in 2006, the International Patent of the OCEANTEC WEC was filed. The Technology was validated through Numerical Simulations and Laboratory Tests in 2007, also the search for investors started the same year after the validation. In 2008 a €4.5m Investment led by IBERDROLA was obtained, and the Technology entirely was transferred to OCEANTEC ENERGÍAS MARINAS, SL. Sea trials of a quarter scale prototype was carried out in the same year as well. Finally, the design of linear absorber or attenuator based on a gyroscopic device for energy extraction was abandoned in favor of an OWC (Oscillating Water Column) with a point absorber.
It is typically known as SPAR BUOY OWC. Floating devices for harvesting energy from waves require at least two interacting bodies, so that energy is extracted from its relative movement. In most concepts, it is necessary to guide the movement of one body along another, requiring the existence of bearings and guidance systems which imply large loads in a hostile environment such as the sea. The goodness of the OWC systems is that one of the bodies consists of water, which besides being economical in the sea, it is guided without any concentrated forces. The size of the OWC is 42 m length and 5 m diameter
The prototype was launched out in Armintza (BIMEP site), in the Northern Coast of Spain in 2016. This area has a depth of 80m.
After 1 year at BIMEP the device will be removed to perform some reworks and substitute the turbines. Re-launching again in summer 2017.
Taking into account that the Oceantec protoype has been installed in BiMEP test site, the key environmental issues are those corresponding to the BiMEP test site.
