The support structure for an Offshore Wind Energy Converter (OWEC) is a vital component in the development of an Offshore Wind Farm. The purpose of the work described has been the design development of a structure to support an 80 m diameter 3 MW wind turbine under the imposed aerodynamic and hydrodynamic forces. Concept evaluations are described for a range of support structure options including both lifted and piled configurations. Further development of two options - a lattice-tower to stand in approximately 25 m water depth in relatively demanding environmental conditions, and a mono-tower in 15 m water depth in a more moderate environment, are presented. Innovative construction and installation techniques are described which obviate the need for the delicate offshore operation of lifting the rotor and nacelle and so totally remove the requirement for a heavy lift vessel - the most costly component of the offshore installation operation.
