Incat Crowther Designs CTVs for U.S. Offshore Wind Market

Incat Crowther has recently secured contracts to design three offshore Crew Transfer Vessels (CTVs) for the U.S. operator Windea CTV.

Two of the CTVs will be built by St Johns Ship Building in Florida and one will be built by Gulf Craft in Louisiana.

The vessels, which are 30m in length feature a large foredeck with a 23 t.m knuckle boom crane and container securing lugs. The vessels incorporate Incat Crowther’s patented Resilient Bow Technology minimizing boat landing impact forces. The  CTVs vessels will have a deadweight capability of more than 50 tonnes. 

"A resiliently mounted superstructure offers excellent comfort for both technicians and crew with six crew berths provided in above deck staterooms. Other notable features include a large wet room and stores warehouse, fully-featured bathrooms and a discreet mess area. Workshop and utility spaces in the hulls are immediately accessible from the cabin," Incat Crowther said.

The vessels will be propelled by quad Volvo IPS propulsion units driven by Volvo DI13 main engines, and will be hybrid-ready.

The CTVs are scheduled to be delivered in 2023 and will go immediately into service for GE Renewables. The vessels will first operate out of New Bedford, MA, during the Vineyard Wind I construction period.
