Crowley christens first fully-electric tugboat in U.S.

San Diego, CA – Joined by diverse partners and industry supporters, Crowley christened the eWolf, America’s first all-electric ship assist harbor tugboat. Operating with zero emissions and other sustainable technology, the tugboat delivers the high-power capability, safety and efficiency that Crowley has made its reputation. The eTug will enter commercial service this week.

“The eWolf is a historic milestone in the maritime industry and Crowley’s legacy, and underscores our company’s commitment to serve as global sustainability leaders and innovators. The all-electric tugboat is the most technologically advanced vessel of its kind, and eWolf will help our customers and communities reach their decarbonization goals while delivering capabilities that strengthen our vital supply chain,” said Tom Crowley, Chairman and CEO.

“We congratulate the people whose tireless dedication brought the eWolf to fruition with our partners at the federal, state and local government, setting a new standard not just in America, but globally.”

Crowley Vice Chairwoman Christine Crowley served as the sponsor to give the blessing and conduct the christening on San Diego Bay.

Built by Master Boat Builders in Coden, Ala., the 82-foot vessel delivers 70 tons of bollard pull – stronger than its conventional predecessor. The eTug also features a fully integrated electrical package for battery energy storage by ABB with advanced technology for mariner safety. eWolf is supported by a new microgrid shoreside charging station that enables the tug to operate at full performance daily on electricity.

Crowley was joined at the vessel christening by project partners including the Port of San Diego, San Diego County Air Pollution Control District, the California Air Resources Board (CARB), the U.S. EPA and the U.S. Maritime Administration. The collaborative effort among federal, state and local partners to decarbonize the port furthers the shared goal of improving air quality for San Diego.

A longtime leader in safe and efficient marine services, the company chose eWolf’s name in a nod to a tugboat in the company’s initial fleet, the Sea Wolf, which operated more than a century ago in California.
