Introduction:This R&D project involves building a 1:10 scale model of an AquaBuOY wave energy converter and followedby open sea testing at the test site in Nisum Bredning on 6.5 meter deep water.The experiment has been designed to demonstrate the function and power generation of the AquaBuOY andthus validate the numerical model. In addition the tests provides AquaEnergy and Ramboll with valuablepractical experience prior to larger scale testing.The full scale AquaBuOY has a diameter of 7 meter and is projected to generate about 250 kW in sea statesof Hs = 5m installed on a water depth of approximately 60 meter. Further optimization is anticipated in laterand parallel stages of the product development program.History of the projectDuring the Swedish wave energy programme in the early 1980 th the company Technocean was created todevelop wave energy in Sweden. Driving forces behind Technocean was a multidisciplinary team ofresearchers from Chalmers University such as professor Lasse Bergdahl, Jan Forsberg og Bengt-OlafSjöström og Lennart Claeson and others [1].During the years 1979 to 1981 the Swedish company Interproject Service IPS in cooperation withTechnocean developed and tested a wave power converter the “IPS Buoy” outside Götenborg in the opensea. The IPS converter is described in [2] and some of the results in [3].The research within Technocean lead to another concept called the “Hose pump project” developed incooperation with the large Swedish company Svenske Varv. The Hose pump project consisting of four floatswas also tested outside Götenborg pumping high pressure water to a small pelton turbine placed on shore.The Swedish wave energy programme ended around 1986 and cooperation between IPS and Technoceancontinued and Gunner Fredrikson CEO of IPS maintained patents. In co-operation with Bengt Olaf theypatented in 1999 the incorporation of hose-pumps in the IPS buoy “the AquaBuOY”.Ocean Tested IPS Buoy Ocean Tested Hose Pump AquaEnergy's AquaBuOY2
