Offshore engineering outfit Dr Techn Olav Olsen's OO-Star WF floating wind concept has taken a leap toward commercialisation, with milestone tank trials now being completed at a research centre in Trondheim, Norway.

The programme at Sintef Ocean, which included a battery of tests on a 1:36-scale model in a range of simulated environments from “benign” Mediterranean to "very harsh Atlantic Sea", is a key step for the innovative semisubmersible design being advanced under the EU's Lifes50+ technology development project as a 10MW nameplate unit.
