Numerical study on the penetration behaviour of drag-embedded anchor
Numerical study on the penetration behaviour of drag-embedded anchor
The Taiwanese Government plans to develop the floating wind turbines for Round 3 offshore wind tenders, including at least one demonstration project. The water depths of the offshore wind farms in Taichung City and Hsinchu County are less than 100 m. The seabed at the sites consists of interbedded noncohesive and cohesive soils. For these offshore wind farms with floating offshore wind turbines, the catenary mooring system with drag-embedded anchors (DEAs) could be an option in commercial development. This study establishes a Coupled Eulerian-Lagrangian method (CEL) finite element (FE) model to analyse the anchor trajectory and holding capacity in cohesive soil with considering the effect of fluke geometry and layered soils. The results show good agreement between the FE analysis and theoretical analysis. The movement directions of the drag anchors are affected by the layered soil conditions significantly.
