The world's first industrial-scale floating wind prototype, Hywind 1, installed in 2009 off the west coast of Norway, will be reborn as an R&D unit, following a deal between developer Equinor and subsea engineering contractor Unitech Offshore.

Moored at the Metcentre offshore wind testing centre off Karmøy, the spar-based unit, known internally as the Hywind Demo, will be renamed Zefyros and used for research projects, new technology development and for teaching and training courses.
