Dominion Energy installs first monopile at CVOW

When completed in late 2026, CVOW will consist of 176 turbines that will produce enough clean, renewable energy to power up to 660,000 homes and is expected to generate fuel savings for customers of $3 in its first 10 years of operation. billions of dollars.

“This is a monumental day for the Coastal Virginia Offshore Wind team, who have worked tirelessly to keep this project on budget and on schedule to provide our customers with reliable, affordable and increasingly clean energy,” said Robert Blue, president and president of Dominion Energy and CEO. “We are taking extensive precautions to ensure this project fully protects the environment and marine species.”

“We are proud to partner with Dominion Energy on this groundbreaking project,” commented Bill White, president of DEME Offshore US. “DEME Orion Equipped with industry-leading Vibro Hammer technology, the vessel has been specifically designed for the efficient installation of massive CVOW monopiles weighing over 1,000 tons. Our talented design team will include qualified American pile drivers, creating a solid and prepared workforce. We look forward to working with our consortium partner, Prysmian, to help bring energy produced in Virginia to the Commonwealth.

The monopile foundations being built at the Portsmouth Marine Terminal are single vertical steel cylinders manufactured by world leader EEW SPC and installed in the seabed to support the wind turbine generators. Under the project’s construction schedule, Dominion Energy will continue monopile installation through fall 2024 and will resume installation in May 2025.

To protect the endangered North Atlantic right whale, no monopiles will be installed between November 1 and April 30, when the whales are expected to migrate past the project area. Additional measures to protect whales and other aquatic life include the use of bubble curtains – perforated hoses through which air is pumped – to create a wall of bubbles around the monopiles during installation and reduce sound waves underwater. The vessels will also be manned by protected species observers and will adhere to speed limits to avoid collisions with protected species.
