Design of monopiles for cyclic loading

With Dr Rasmus Tofte Klinkvort, Senior Consultant, NGI (Norwegian Geotechnical Institute)

Offshore wind turbines are placed in loading environments with actions from wind and waves transferred through the monopile to the soil as cyclic loading. It is well established that cyclic loading of soil may lead to pore pressure accumulation and loss of effective stress and strength. The effect of cyclic loading therefore needs to be addressed when designing monopiles. This presentation will present a methodology to design monopiles for cyclic loading using a simplified approach. The methodology can be used together with simple spring models or more advanced finite element models.
