The innovative next-generation TetraSpar floating wind power concept devised by industry pioneer Henrik Stiesdal is safely anchored off Norway, soon to start sea-trials.

Installation contractor Bourbon Subsea Services (BSS) reports the unit, which is topped with a 3.6MW Siemens Gamesa turbine, is now hooked-up to a pre-laid mooring lines and power cable in 200 metres of water at the MetCentre testing site off Karmøy, in the west of the Nordic country, and set for final commissioning “in the coming weeks”.
