Influence of Wave Spreading in Short-term Sea States on the Fatigue of Offshore Support Structures at the Example of the FINO1-Research Platform

The distribution of wave directions within a short-term sea state has a relevant influence on the fatigue loading of offshore structures. Measurement data collected at the FINO1 research platform will be used to demonstrate the effect. A better agreement between simulation and measurement can be achieved if wave spreading is taken into account in the simulation of the sea states. The effects of considering wave spreading both in the short-term as well as in the long-term will be studied at the example of a monopile and a tripod.
