Germany's EEW sends first batch of eight monopiles for largest US offshore wind farm

The 2.6GW project being developed by Dominion will deploy 176 foundations off the Virginia coast

German steel fabricator EEW sent its first batch of eight extra-large monopile offshore wind foundations en route to Dominion Energy’s 2.6GW Coastal Virginia Offshore Wind (CVOW) array, the US’ largest, under development 27 miles (43 km) off the coast of Virginia Beach.

These are the first of 176 monopile foundations that EEW will provide for the project out of its Rostock, Germany factory.

EEW – which previously delivered two monopiles for the 12MW CVOW pilot in April 2020, the first foundations to be installed in federal US waters – is set to process more than 200,000 tons of steel for the CVOW installation.

The foundations, each 83 metres long, weighing 1,538 tonnes and with a diameter up to 9.5 metres, will arrive at the project’s marshalling port at Portsmouth Marine Terminal in Portsmouth, Virginia in early October.

The project recently received its environmental nod from offshore energy regulator Bureau of Ocean Energy Management (BOEM), clearing the way for full approval and at-sea installation.

Skirted inflation

In contrast most of the US sector that has struggled with spiralling costs, Dominion contends that its nearly $10bn project has skirted the worst of inflation by signing supplier contracts for some 90% of its supply chain needs totalling around $7bn prior to costs hikes starting in 2022.

The utility signed its monopile contract with EEW in 2021. That same year it signed up contractors DEME and Prysmian to a record-setting $1.9bn deal that will see the European duo install EEW’s monopiles as well as power transmission infrastructure for the giant array slated to be online in 2026 and will supply electricity to 660,000 homes in the Commonwealth once to full power.

Virginia is placing a large bet on offshore wind for its energy transition and the associated economic development the sector will bring, such as Siemens Gamesa pledge to build a $200m blade factory in the Port of Virginia, initially to supply the CVOW project, where it has preferred supplier status to provide its 14.7MW turbies.
The Port of Virginia will also stage and pre-assemble turbine foundations for CVOW at its Portsmouth Marine Terminal, starting in 2024.
