July 2, 2025 — The next offshore service operation vessel (SOV), ECO Liberty, was christened to officially enter the U.S. fleet in support of the offshore wind sector. The vessel, which was completed in May, has been in jeopardy after the Trump administration suspended work on the Empire Wind project, but with work back underway, the vessel was named in New Orleans, Louisiana on June 28 by Louisiana’s First Lady Sharon Landry.
The 262-foot (80-meter) hybrid-powered ECO Liberty will be homeported at New York’s South Brooklyn Marine Terminal, where more than 2,000 workers are constructing the staging facility, O&M base, and control center for Empire Wind. The ECO Liberty will be deployed to support ongoing marine construction in the lease area and eventually serve as the floating home for Empire Wind’s skilled workers when stationed offshore.
The vessel is 5,700 GT. It provides accommodations for up to 60 workers and is designed to remain offshore at the site to support the construction and later maintenance operations.
The vessel was built by Edison Chouset Offshore, which continues to own the vessel through its offshore division. It will be operating on a long-term charter to Empire Wind, which is being developed by Equinor. Empire Wind is located 15 to 30 miles southeast of New York’s Long Island and spans 80,000 acres, with water depths of between approximately 75 and 135 feet. Offshore work started this spring for the project, which will have a capacity for 810 MW when completed.
