Images: First U.S.-built Wind Turbine Installation Vessel Undergoes Sea Trials

Seatrium has begun sea trials for Charybdis, the first U.S.-built Wind Turbine Installation Vessel (WTIV) compliant with the Jones Act.

The vessel is 96% complete and remains on track for delivery in 2025. It has been constructed at Seatrium’s AmFELS shipyard in Brownsville, Texas.

Charybdis is commissioned by Dominion Energy and designed to support offshore wind projects in U.S. waters. It recently passed critical tests, including a jacking trial and main crane load testing.

The vessel is expected to play an important role in the Coastal Virginia Offshore Wind project after final preparation works, such as grillage installation, are completed.

It has a length of 472 feet, width of 184 feet, and depth of 38 feet and is among the world’s largest WTIVs. It features a 426-foot crane with a lifting capacity of 2,200 tonnes and can accommodate up to 119 people.
