Floating offshore wind is opening new possibilities for wind power locations and will play a critical role in the transition to a cleaner energy supply, contributing significantly to an increase in offshore wind power. DNV enables floating offshore wind commercialization by providing digital tools and guidance to develop safe, reliable and cost competitive projects. Using the DNV software packages for OWTs, the floater substructure can be modelled in Sesam and its hydrodynamic properties can be determined. This is then used in Bladed in a coupled analysis of the complete system of floater and wind turbine. The output can then be used in Sesam for analysis of the floater substructure, in Sima for mooring and cable design, while turbine design can be performed using Bladed.
