Numerical analyses of a multiline ring anchor for floating offshore wind turbines in sand
The multiline ring anchor (MRA) is a novel anchor system proposed for the emerging floating offshore wind technology. The ring-shaped anchor concept comprises of an embedded ring anchor connected to multiple mooring lines, allowing sharing of anchors amongst multiple platforms, and thus resulting in a significant reduction of the total number of anchors and installations required. Apart from being cost efficient, the MRA can be installed deep into the seabed, resulting in the mobilisation of a higher soil resistance. The present paper assesses the performance of the MRA in sand soils where its behaviour is investigated under monotonic loading conditions using a three- imensional (3D) finite element (FE) model capable of making reliable estimates of axial and lateral ultimate capacities. Data on the anchors behaviour from centrifuge tests under similar loading conditions are employed as a calibrating tool for the numerical model.
