Swedish wind turbine maker SeaTwirl received the go-ahead to check its 1 megawatt (MW) S2X vertical-axis floating offshore prototype in Norway.

Vertical-axis floating wind turbine pilot

In March 2022, Norway’s Ministry of Vitality gave approval to SeaTwirl and Norwegian offshore wind take a look at middle Marine Vitality Check Centre to pilot the vertical-axis floating wind prototype for 5 years at a former fish farm in Boknafjorden, northeast of Lauplandsholmenoff, 700 meters (2,297 ft) from the coast.

However 4 teams – the Norwegian Environmental Safety Affiliation, the Norwegian Fishermen’s Affiliation, and two marketing campaign teams – appealed in opposition to SeaTwirl’s allow, and so the mission was placed on ice.

Yesterday, the Norwegian Water Assets and Vitality Directorate rejected the enchantment, so SeaTwirl’s S2X pilot can now proceed, and no additional appeals can be thought of.

CEO Peter Laurits mentioned:

Our major focus is the commercialization of huge generators, SX, in floating wind farms. The end result offers freedom to decide on and plan the set up of S2x in the way in which that finest helps that objective.

How S2X works

SeaTwirl says that “a number of S2xs will be positioned in a dense sample for elevated output.” The corporate’s reasoning for constructing vertical (as a substitute of horizontal) axis floating generators is that this:

The simplicity of the design and low middle of gravity are the large benefits. All shifting elements and electrical programs are simply accessible [and] near the water’s floor, reducing upkeep prices.

The S2X prototype is 55 meters (180 ft) above sea stage, and it’s round 80 meters (262 ft) beneath sea stage. The turbine diameter is 50 meters (164 ft). Its rotor blade top is round 40 meters (131 ft). Its optimum working depth is 100 meters (328 ft) and deeper.

SeaTwirl isn’t the one firm testing vertical-axis wind generators off the Norwegian coast – earlier this month, aluminum and power big Hydro and floating wind specialist World Large Wind introduced that they’re going to check a vertical-axis wind turbine made out of aluminum.
