Foundation Technologies for Offshore Deep Water Renewable Energy EVALUATED
Floating platforms for bearing offshore wind turbines are fast becoming required to produce renewable energy from the wind capacity in the Atlantic, Mediterranean and deep North Sea. These platforms can be attached by way of mooring lines and anchors embedded in the seabed. The purpose of this study was to investigate the reaction of the soil on different types of pile anchors. A numerical study of anchor piles was performed by using the finite element software Abaqus. Several two-dimensional and three-dimensional models were simulated with different pile lengths and embedded in soils with different failure criteria. First, an elastic behaviour for the pile and soil was simulated. After, the analysis focused on the reaction of undrained, clayey soil with the failure criterion of Tresca. As well as axial, lateral and combined loads were examined. The effect of the pile length to diameter ratio was analysed in an undrained soil with constant and with varying cohesion.
