The University of Maine (UMaine) VolturnUS-S reference semi-submersible (Allen et al., 2020) is a generic steel version of the UMaine patented concrete floating foundation technology developed in collaboration with the U.S. Department of Energy (Viselli et al., 2016). According to UMaine, “the reference design aims to serve the wind industry by providing a publicly available design benchmark to explore new technologies and design methodologies while facilitating collaboration between industry and researchers”.
The overall layout of this example is as follows:
•Introduction gives an overview of the UMaine semisub, the IEA 15MW turbine and ROSCO controller, and the load cases simulated.
•Model Summary describes the Flexcom model in detail.
•Results from Flexcom are presented, alongside results from the UMaine report where possible.
