Hywind Floating Wind Installation Challenge Named as one of the three winners of Equinor’s innovation campaign, the Hywind Installation Challenge, which looked at options to improve the Hywind turbines assembly and installation sequence to make the concept more cost effcient and available in more markets around the world. Our offshore oil and gas teams in the UK and North America, and UK-based renewables team developed a design of multiple turbines attached to a reusable transportation frame.
