Integrated numerical modelling of soil-anchor-mooring line-floater response for floating offshore wind
Integrated numerical modelling of soil-anchor-mooring line-floater response for floating offshore wind
This paper presents the development of an anchor macro model and its integration with mooring analyses, for easy coupling of the anchor-seabed-mooring response and full system modelling of a floating offshore wind turbine. The model combines techniques that (i) mobilise additional seabed resistance by considering the added mass and whole-life effects of changing strength of the seabed and (ii) reduce the anchor loads by considering a compliant mooring system, to result in reduced required anchor size. The benefits of combining these approaches lead to reductions of up to 50% in the minimum required anchor size for the same system reliability.

Abstract
This paper presents the development of an anchor macro model and its integration with mooring analyses, for easy coupling of the anchor-seabed-mooring response and full system modelling of a floating offshore wind turbine. The model combines techniques that (i) mobilise additional seabed resistance by considering the added mass and whole-life effects of changing strength of the seabed and (ii) reduce the anchor loads by considering a compliant mooring system, to result in reduced required anchor size. The benefits of combining these approaches lead to reductions of up to 50% in the minimum required anchor size for the same system reliability.
