OC3—Benchmark Exercise of Aero-elastic Offshore Wind Turbine Codes

Abstract

Establishment of a suite of benchmark simulations to test new codes and train new analysts Identification and verification of code capabilities and limitations of implemented theories Investigation and refinement of applied analysis methodologies Investigation on the accuracy and reliability of results obtained by simulations to establish confidence in the predictive capabilities of the codes Identification of further research and development needs These objectives are achieved by a sophisticated approach investigating different types of bottom-mounted and floating support structures. Although the emphasis of the benchmark exercise is put on the support structure, various issues, important to the overall dynamics of offshore wind turbines, the turbulent inflow and the aeroelastic behaviour are investigated in the course of the project.
