Foundations for offshore wind turbines
A foundation for an offshore wind turbine installation. The foundation is made of at least three suction caissons 16 and a connector body 22, the connector body having radially extending arms 50 that connect the caissons to a central hub. Each of the caissons has an upright tube consisting of: a lower tube 42 defining an open-bottomed suction chamber; an upper tube 44 defining a ballast receptacle 46; and an internal partition 38 that divides the lower tube portion from the upper tube portion. Each arm terminates by the upper tube portion of the associated suction caisson. Each arm may be a box-section structure which may be closed by the upper tube portion of the associated suction caisson and may have top and bottom walls. The partition of each caisson may be coplanar with the bottom wall of each arm. The top wall may be level with or bellow a top edge of each upper tube portion. The foundation may also have a curtain system (72, fig. 9) suspended from each arm.
