SeaGen Tidal Turbine Performance Appraised by DNV

Det Norske Veritas (DNV), a certification and classification agency for international marine and offshore development services, has made a statement of conformity manifesting the functioning of the SeaGen tidal turbine with 1.2 MW capacity manufactured by Marine Current Turbines (MCT).

The issuance of certification corroborates that the functions of the tidal turbine are correctly measured by following the laid out procedures of the Edinburgh Protocol prepared by the University of Edinburgh. The university has developed the procedures at the behest of the Department of Energy & Climate Change (DECC) of the U.K. government and on the basis of the testing protocol laid down the European Marine Energy Centre (EMEC). The results of the testing denote that the developed tidal wind turbine has achieved the goals of design with 48% peak efficiency in both of its rotors during both in and out tide conditions with a maximum efficiency of 52% and a minimum efficiency of 45%.

The tests on its overall system efficiency after counting on performance losses in the gearbox, generator and power electronics function was in the range of 40-45% and assessed as the power producing and delivering efficiency of the tidal turbine rotors of SeaGen.
