After decades of starts and stops and two operating pilot projects, commercial offshore wind installation began this week with the driving of the first foundations for Vineyard Wind 1.

The 800MW project off the coast of Northeast state of Massachusetts owned by Copenhagen Infrastructure Partners (CIP) and Iberdrola-controlled Avangrid has been under development for around a decade and is the first to be fully approved by state and federal regulators.

“We can finally say it – as of today, there is ‘steel in the water,’” said Vineyard Wind CEO Klaus Moeller. “Over the next few months, we’ll be working hand in glove with the Building Trades and our contractors to ensure the work is done safely and efficiently.”

The foundations are being installed by the offshore construction firm Deme’s Belgium-flagged, 216-metre wind turbine installation vessel (WTIV) Orion.
With a heavy lift crane by Liebherr cable of lifting 5,000 tonnes, Orion is one of the few WTIV globally capable of handling the project’s massive, 1,895-tonne monopiles fabricated by German manufacturer EEW.
The foundations are being hauled directly to the Orion from Germany at the lease area 15 miles (32 km) south of Martha's Vineyard in the Massachusetts wind energy area.
Orion will be replaced by WTIV Sea Installer for the installation of the array's 13MW GE Haliade-X turbines, which will be the most powerful in the world.

Vineyard plans on installing around half of its 62 turbines this year, when it will begin sending power to the Massachusetts grid.

Orion will return in the spring of 2024 to instal the remainder of the turbines and the project expects to be fully commissioned at the end of next year.
