We are providing detailed engineering and design services for the onshore portion of Dominion Energy Coastal Virginia Offshore Wind (CVOW), one of the largest offshore wind initiatives in the U.S. We are supporting the underground transmission of the nearly 3 gigawatts (GW) of offshore-generated renewable power to a new onshore substation. The project is a key part of Dominion Energy’s initiatives to meet clean energy targets.

We performed detailed design for nine 230-kV high-voltage alternating current (HVAC) circuits that establish the critical link between the offshore substations and the new onshore substation located 3.5 miles inland from the initial cable landfall. To facilitate the cable transition from sea to land, we engineered direct-pipe trenchless installations, enabling the safe and efficient landing of submarine cables without disrupting sensitive coastal environments.

Given the site’s challenging sandy soils, our design included multiple foundation support options to ensure long-term structural stability and to prevent buoyancy or settlement issues. This work was underpinned by comprehensive geotechnical investigations and nearshore surveys.
