Abstract

The Technical University of Denmark (DTU) has defined a rotor, medium‐speed geared drivetrain, land‐based tower and controller for a 10‐MW wind turbine (Bak et al., 2013; Hansen and Henriksen, 2013). The Norwegian University of Science and Technology (NTNU), in partnership with the NOWITECH Research Centre for Offshore Wind Technology, developed a direct drive shaft and generator design for a 10‐MW turbine tailored to deep water, high wind locations (Dahlhaug, 2012; Smith, 2012; Khan, 2012; Singh Klair, 2013) and dimensioned a piled offshore foundation, transition piece and tower, at a location whose water depth (30 m) and seabed conditions are representative of those at the Dogger Bank. These designs were combined into the 10‐MW Offshore Reference Wind Turbine (ORT), used as a case study in this chapter.
