At Fraunhofer IWES a Modelica Library including all major components needed for load calculations of current offshore wind turbines is developed. The library additionally includes models for external conditions; like wind; soil and waves; and their respective influence on the structures. The library constitutes a large effort in the creation of a highly coupled multiphysics model with Modelica for an industrial project. The results obtained with this library are compared to the results from the IEA Wind Task 23 project OC31 (Offshore code comparison collaboration). The OC3 project is an international effort to define a set of loadcases and a reference wind turbine that are used to verify simulation systems on a code-to-code basis. In this paper the status and the implemented theories of the individual models at IWES are explained and verification results are presented and discussed.
