Hydrodynamics, Soil Characteristics and Floating Wind Turbines
Abstract Support structures for offshore wind turbines fall into two distinct types. Bottom-fixed turbines are connected to the seabed in a manner that restricts vertical motion; key examples of this class of concepts include monopiles, gravity-based structures, or jackets. Commonly, a transition piece connects the turbine tower and support structure. For monopiles this traditionally involves a grouted connection, but grout failure issues have recently led to a revision of the design practice and standards. A coning shape of the matching surfaces with or without shear keys is now increasingly employed for securing the transition piece and an overall higher quality of the grout connection. The seabed connection can be in the form of hammered or drilled piles, or suction buckets. Alternatively and with gravity-based solutions the mass of the support structure can be used for a stable and secure structure-seabed interface. Offshore bottom-fixed turbines have been realised routinely in commercial wind projects since the late 1990s, but the current market situation is characterised by continuously increasing water depths and a trend towards bigger turbines. This in turn leads to a constant shift away from the current state-of-the-art and to increasingly larger support structures.
