Dominion Resources, Inc. Email Newsletter: April Monthly Mariner’s Update (April 3, 2024)

Hello Marcos,

Offshore construction work for Coastal Virginia Offshore Wind (CVOW) commenced in late February 2024 with the first seabed disturbing activity — the relocation of the first Munition of Explosive Cocner. Throughout this process, we remain committed to maintaining communications with mariner and fishing communities.

The goal of our monthly email updates is to give a high-level overview of ongoing and planned near-term construction activities and the vessels involved. Questions regarding construction operations are welcomed and can be directed here.

Mariners are encouraged to contact Dominion Energy’s Fisheries Liaisons with any specific questions about CVOW project activities in relation to fisheries. Additional project information is available on the CVOW project website. Sign up to receive USCG Local Notice to Mariners Updates here.

Mariners and the public are reminded that due to the nature of the construction activities, project vessels may be restricted in their ability to maneuver. It is requested that mariners communicate with project vessels on Channel 16 VHF to coordinate any necessary passing arrangement. Safety vessels will be on scene to assist with the coordination of commercial and public marine traffic and project vessels.

Project Background Information

CVOW is a 2.6-gigawatt offshore wind energy project that will consist of 176 wind turbines located 27 miles off the coast of Virginia Beach, three offshore substations, undersea cables and new onshore transmission infrastructure to deliver emissions-free wind power to homes and businesses.

Munitions and Explosives of Concern (MEC) Identification and Relocation

Vessels will be working on relocation activities in and around the export cable corridor offshore, followed by relocation in the lease area and then closer to shore east of the Dam Neck Ocean Disposal Site (DNODS).

Disposition activities started in ALARP Area 2 in late February along the export cable corridor and will then move to the WTG sites in ALARP Area 3.

The M/V Atlantic Breeze will be conducting light debris relocation in support of the MEC relocation work throughout the cable corridor.

Direct Pipe Punchout Construction

Construction activities onshore at and offshore of State Military Reservation (SMR) have begun, supporting the export cable landing sites, which will run via underground conduit from a transition bay shoreside of the beach to predetermined positions offshore.

The first phase of installation has been completed, and operations have been paused with plans to resume in June.

Component Arrival

There are several scheduled arrivals of components to Portsmouth Marine Terminal (PMT) in April, including 12 additional monopiles, 12 offshore substation pin piles and grout silos.

Fisheries Resource Characterization Studies

In partnership with the Virginia Institute of Marine Science (VIMS), the Virginia Marine Resource Commission (VMRC) and commercial fishermen, Dominion Energy is conducting resource assessment studies for Black Sea Bass, Channeled Whelk and Atlantic Surfclam in and around the project area.
