Session description Among the wind energy community there is a common notion that dedicated offshore wind turbine designs are needed in order to realise the ambitious goals of various governments and the EU, and to make offshore wind energy more competitive. Currently, offshore wind turbines may be considered derivatives of wind turbines designed for land applications. Features of those dedicated offshore machines include, amongst others, lighter constructions, high speed rotors and design for reliability (simplicity). All of these aspects will be addressed in this session. Two of the presentations will discuss the first results of multi MW existing wind turbine types, which will provide very valuable input to the debate on reliability. Specific design issues for dedicated offshore wind turbines, including up-scaling, simplicity versus the need for load alleviation and harsh eternal conditions will also be presented in this session. Finally, the most important component of a wind turbine, the rotor, will be discussed in terms of making extreme lightweight blades and increasing the tip speed ratio, both of which are essential elements in realising cost reductions on the longer term. |
