The purpose of this report is to present COREWIND results related to mooring and cable design and its influence on FOWT response as well as design recommendations from the structural point of view. Results from station keeping predesign, mooring optimized designs, cable influence and experimental results are used to perform an overview analysis of the mooring and cable influence. Design recommendations are given from a structural point of view. First, a standard review for structural design is performed. Second, the main design bases followed for the design are presented, and, third, some detailed examples for the designs are given, for the whole platform, as well as for particular zones like the mooring connection points.
