The pilot, in a 57sq-km site 19km offshore in 140-158 metres of water, will be built around a quartet of second-generation Hywind spar-type hulls outfitted with 3MW turbines.

“On the commercial side, this is one of the biggest obstacles [overcome],” Statoil project manager Kristin Aamodt tells Recharge. “It is a real achievement.

“This project will show that these turbines can be deployed in a [wind] park setting, that you can reduce cost significantly from the one-off demo unit.
