Edison Chouest Offshore (ECO) is constructing mini-crew transfer vessel designed by Chartwell Marine

U.S. offshore vessel operator, builder and owner Edison Chouest Offshore (ECO) is constructing the U.S. offshore wind industry’s first ever mini-crew transfer vessel (CTV), designed by U.K.-based Chartwell Marine.

Set to enter service in summer 2024, the 39-foot catamaran will serve as a daughter craft deployed from ECO’s ECO Edison, the first U.S.-built service operation vessel (SOV). The vessel has capacity for up to 12 personnel and is designed to be deployed from ECO Edison during extended offshore stays, offering access to turbines, vessels and other project infrastructure across the Revolution Wind, South Fork Wind and Sunrise Wind offshore wind farms being developed by Ørsted and its joint venture partner Eversource Energy in the U.S. Northeast.
