Abstract
A fatigue analysis is being carried out for a wave energy converter subjected to ocean wave loads. The device is a bottom fixed structure, located in a shallow water environment. Interest is focused on the local stress response of a structural detail and a subsequent calculation of its fatigue life by using the rainflow counting approach. The wave energy converter is characterized by its ability to enter in a storm protection mode which - whenever extreme conditions occur - will drastically reduce the exposure to wave loads. The predicted fatigue life is calculated for two different control cases. Finally the question will be answered which control strategy is more favorable regarding the trade off between fatigue damage reduction and power production on the wave energy device.
