43. Largest Existing Offshore Turbine is REpower 5M Beatrice Project in North Sea will demonstrate two REpower 5-MW turbines in offshore application for the first time. Other firsts for Europe include: Deepest water (45 m depth) Farthest offshore (25 km) Tower platform and anchoring concept 750-tonne truss-work platform Rotor diameter = 126 m Suction-caisson anchor 410-tonne turbine and 210-tonne tower Each rotor blade weighs 18 tonnes Sep 2004 installation of turbine rotor in onshore prototype at Brunnsbutel, Germany, in Schleswig-Holstein

47. VCERC submitting a CRADA Proposal to Develop Large-Blade Testing Facility Opportunities to develop remote structural monitoring methods for non-destructive testing of long,composite aerospace structures Wind turbine blades require static (bending, twist) and dynamic (fatigue) load testing to ensure durability for book life of project. No North American test facilities now exist that are capable of testing 70 m long blades.
