The effects of operational loads and wind loads on offshore wind turbines are well understood.
At most sites, however, the water depth is such that breaking or near-breaking waves will occur causing impulsive excitation of the foundation and consequently, considerable stresses and displacements in the foundation, tower and turbine.
WiFi aims to improve the way effects of steep (and breaking) waves are taken into account in the design methodology of fixed offshore wind turbines, so that optimised turbines can be developed.
Kicking off in Q2, the Joint Industry Project (JIP) will run for three years.
