Abstract: This paper presents the main objectives of the research project “GIGAWIND alpha ventus” in regard to the assessment of wind-and wave loads for supporting structures of offshore wind energy converters. The multiple sensor-equipped tripod structure for the acquisition of test field data in approximately 30 m water depths is presented here. Preliminary results from laboratory experiments with the objective to determine wave slamming and non-breaking wave forces on foundation structures are given exemplarily. Three dimensional numerical models combined with laboratory experiments and field data will be used. Temporal and spatial highly-resolved modelling of design loads are developed and validated to provide calculation methods for an efficient mass production of offshore wind turbines.
