Spanish company Esteyco has sucessfully completed installation of an offshore turbine atop a telescopic tower and float-and-sink gravity base foundation both made of concrete.

The so-called Elican prototype is in place at the Plocan test site off the island of Gran Canaria with generation from the Siemens Gamesa 5MW nacelle due to commence in the fourth quarter of the year.

UK company Ale Heavy-lift, which was part of the Horizon 2020 team working on the project, said this was a first of its kind project.

“It does does not need large, costly offshore equipment for its installation thus reducing the overall installation cost about 30%,” it said.

"All of the wind turbine’s components are assembled onshore in the port then the turbine is towed into its offshore position by tugs, making it a more efficient and economic methodology,” it added.
