Florida-based marine company Crowley has taken delivery of eWolf, the first all-electric, ship-assist harbor tugboat in the U.S.

Crafted under the expertise of Florida-based Crowley, the 82-foot (25-meter) eWolf is designed as a zero-emission vessel as it would operate fully electric.

eWolf has a 6-Mwh energy storage system with sufficient capacity enabling the vessel to deliver one full day of normal work without using a drop of fuel. 

“The eWolf will provide services through its advanced vessel control technology and first-in-class energy features, while providing the safety, quality and reliability that Crowley and our mariners are known for,” said James Fowler, senior vice president and general manager of Crowley Shipping.
“We are thrilled to reach this important achievement for our company and the U.S. maritime industry through the collaboration with our partners.”

The vessel was developed through collaboration with federal and California agencies, under the watchful eye of Crowley Engineering Services and the Jensen Maritime Naval Architecture and marine engineering group.
