NORWICH, UK – Acteon has assisted Siemens Gamesa with a cable survey for Dominion Energy’s Coastal Virginia Offshore Wind (CVOW) pilot project, 43.5 km (27 mi) from the Virginia coast.
The export cables are around 45 km (28 mi) long and the array cables are 1 km (0.62 mi) in length.
TerraSond, part of Acteon’s geo-services division, performed the survey from the Atlantic Endeavor, the CVOW project’s dedicated crew transfer vessel, which was modified by provider Atlantic Wind Transfers for the campaign.
The arrangement avoided the need to mobilize a dedicated survey vessel.
Last September, Acteon entered an agreement with Siemens Gamesa to jointly provide a fully integrated offshore wind turbine operations and maintenance (O&M) service for the CVOW pilot.
The two companies have been working to optimize the wind turbine service and balance of the plant O&M work scopes for the 12-MW, two-turbine installation.
Both the Siemens Gamesa SWT-6.0-154 offshore wind turbines have been operational since October. Dominion will use experience from the pilot to support its proposed 2.6-GW commercial project, which is due to start construction in 2024.
