Abstract

An offshore wind turbine (OWT) analysis relies on aero-hydro-servo-elastic simulation tools, which take into account an interaction of various environmental conditions and the entire structural assembly of the turbine, including its control system. For the more confident analysis of loads imposed on OWTs located in ice infested regions, an additional interface between sea ice loading and a support structure is necessary. Two ice load models are interfaced with OneWind, a library for a couple, time domain simulation of OWT developed at Fraunhofer IWES (Strobel 2011). The first model is a procedure for soil-structure-ice-interaction (PSSII) used for vertical structures. The second an ice load model for simulation of the stochastic ice bending failure on a support structure with cone. A simplified OWT with a monopile support structure was considered. The nacelle and rotor assembly was modelled as a point mass at the top. In OneWind an interface for importing ice forces was build. The response of a structure and horizontal ice forces was simulated with PSSII procedure. Then, ice forces are imported with the interface into OneWind, where a structure response is re-simulated. A comparison of the structural response simulated with a standalone PSSII procedure and OneWind produces satisfactory results in terms of displacements. In addition, the difference between the standalone PSSII and OneWind comes from the fact that PSSII is based on modal analysis, whereas OneWind is based on a finite element method. Ice forces on conical support structure are generated by the ice load model and import as well with the interface into OneWind. The structural responses were simulated with Abaqus and OneWind. The comparison of the simulated structural responses shows a good agreement
