First CVOW Offshore Substation Jacket En Route to US

December 4, 2024, by Adnan Memija

The first of three offshore substation jacket foundations has departed from the Danish Port of Esbjerg and is en route to the US, where it will be installed at the 2.6 GW Coastal Virginia Offshore Wind (CVOW) project.

In 2021, a consortium comprising Semco Maritime and CS Wind Offshore (previously Bladt Industries) was awarded a contract for the supply of three 880 MW substations for the offshore wind project, developed by Dominion Energy.

CS Wind Offshore is responsible for the design, procurement, and manufacturing of the steel structures and jacket foundations for the substations, while the design, procurement, and installation of electrical equipment, energy systems, and inter-array cables will be managed by Semco Maritime.

The first of three offshore substation jacket foundations, weighing approximately 2,445 tonnes and standing 60 metres tall, has been transferred to a transportation vessel and is on its way across the Atlantic.

The four pin piles for one offshore substation jacket are already installed at the site 27 miles off the coast of Virginia Beach.

The first of three 880 MW offshore substations arrived at the production site in Aalborg, Denmark, in January this year.

As reported, Dominion Energy selected a consortium of DEME and Prysmian as the Balance of Plant (BoP) contractors in charge of the transportation and installation of the foundations and the substations, and the engineering, procurement, construction, and installation (EPCI) services for the inter-array and export cables.

Recently, DEME Offshore contracted JDR Cable Systems for cable installation and commissioning work on the CVOW project.
