TP Installation Coming up at America’s First Large-Scale Offshore Wind Farm

April 30, 2024, by Adnan Memija

The installation of transition pieces (TPs) is about to commence at Vineyard Wind 1, America’s first large-scale offshore wind farm.

Beginning next month, DEME Group’s jack-up vessel Sea Challenger will begin placing TPs at 17 monopile locations in lease area OCS-A 0501. The campaign will continue through June 2024.

The units are being manufactured by Spain’s Windar Renovables, which won the contract in 2019.

The first of 62 transition pieces arrived at the Port of Avilés in December 2022. DEME Offshore US is responsible for the transportation and installation of the units.

In addition to TPs, DEME’s wind farm installation vessel Sea Installer has installed ten wind turbines so far at the offshore construction site located about 15 miles (approximately 24 kilometres) off the coast of Massachusetts.

The first GE Haliade-X 13 MW wind turbine was installed at the site in October 2023 and the offshore wind farm produced its first power in January 2024.

A month later, five of the planned 62 units were delivering energy to the New England grid, generating 68 MW of clean energy, enough to power 30,000 homes in Massachusetts, according to the developers of the project, Avangrid and Copenhagen Infrastructure Partners (CIP).

Once completed the project will generate 800 MW, enough to power more than 400,000 homes and businesses across the Commonwealth, while reducing carbon emissions by over 1.6 million tonnes per year.
