Seawind Ocean Technology has developed a complete offshore wind energy system to bring the LCoE below 9 cents reducing CAPEX and OPEX and extending the life-time of the system to 30+ years. Seawind uses a two-bladed wind turbine head with an elastic teetering hinge, which prevents the moments coming from the rotor action reach the drive train. The drive train of the Seawind 6 only sees rotor torque, no bending moments and no gyroscopic momentum as the elastic hinge eliminates the gyroscope, which a wind turbine with a ridged rotor represents. This enables the Seawind 6 wind turbine to control the power of the turbine simply by yawing, not bypitching blades, reducing the complexity of the wind turbine. The elastic rotor coupling also reduces drastically fatigue and ultimate loads on rotor, drive train and the entire turbine structure. The Seawind 6 is designed for 25 years of lifetime and will operate 30+ years in the rough sea environment with a lifetime extension program due to very low fatigue values. The two-bladed configuration opens up assembly and installation methods, based on sinking of the entire unit at the site; rather than constructing the offshore wind turbine at sea. Installation of the system and any maintenance operation do not require heavy and costly crane vessels or jack-ups. The system is designed to allow maintenance and operation on board and has a double access: via sea and via the strong helideck for double engine helicopters mounted on the self-sustaining steel nacelle body.
Martin Jakubowski is a serial entrepreneur active in the renewable energy sector since the late 80s. He has developed, built and operated hydropower plants and onshore wind farms in several European countries and set up green energy distribution companies among which Good Energy Plcin the UK listed at the London Stock Exchange. In 2008, he installed with his long term partner Silvestro Caruso, the world’s first floating wind turbine in the Italian Southern Adriatic Sea with Blue H. Since then he is developing the complete offshore wind energy system based on aproprietary two-bladed wind turbine technology.
