US-based and privately-owned Crowley, founded in 1892, has accepted delivery of the first all-electric harbour tugboat in the U.S. named “eWolf”.

The tugboat is constructed by Master Boat Builders at its shipyard in Coden, Alabama,and she was designed by Crowley’s engineering services team.

“eWolf” will operate with zero emissions while providing the complete performance capabilities of a traditional tug, by using ABB’s innovative, integrated electrical propulsion system.

Crowley states that she will generate 178 tons less of nitrogen oxide (NOx), 2.5 tons less of diesel particulate matter and 3,100 metric tons less of carbon dioxide (CO2) over the first 10 years of its operations, which is the equivalent of removing 350,000 gallons (about 1.325 million liters) of gas from use, according to EPA calculations.

The 82-foot harbor tug “eWolf” will after transport and final demonstration trials operate at the Port of San Diego.

After the completion of Crowley’s microgrid shoreside charging station at the port, Crowley notes that the Harbour towage operations are expected to begin in spring 2024.

James Fowler, senior vice president and general manager of Crowley Shipping, said that “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.”

“We are thrilled to reach this important achievement for our company and the U.S. maritime industry through the collaboration with our partners,” he added.

Garrett Rice, president of Master Boat Builders, pointed out that “The eWolf demonstrates where the maritime industry can go, in terms of both innovation and sustainability, with solid partnerships between owners, designers, suppliers and shipyards.”

“We are proud to have partnered with Crowley in the construction of the eWolf and look forward to seeing her at work in San Diego very soon.”
