Abstract
WINDMOOR is a Competence Building Project (KPN), with the main objective of improving the under-standing of loads governing the mooring system design of floating wind turbines (FWTs). As a base case, the project adopts a semi-submersible platform supporting a 12 MW wind turbine. This report describes the platform, mooring system, and wind turbine adopted. A detailed analysis of the platform hydrody-namics is provided, as well as the design of the 12 MW wind turbine developed for the project. Following, a SIMA model for the FWT is presented. The research leading to these results has received funding from the Research Council of Norway through the ENERGIX programme (grant 294573) and industry partners.
