Crowley Unveils First Fully Electric Harbor Tugboat In The US, eWolf

Crowley has reportedly accepted the delivery of eWolf. This first-ever all-electric vessel assists harbor tugboat in the U.S. This is a significant milestone in advancing the firm’s dedication to sustainability and decarbonization. The 82-foot tug tugboat, designed by Crowley’s expert engineering services team, will operate with zero emissions while offering full performance capabilities of a conventional tug.

Constructed by shipbuilder Master Boat Builders, it is expected to enter service at the Port of San Diego this spring after the final trials and successful completion of Crowley’s micro-grid shoreside charging station.

The vessel is designed for ABS class and is fully compliant with the regulations of the U.S. Coast Guard Subchapter M. To bring eWolf to life, Crowley collaborated with the Port of San Diego, the California Air Resources Board (abbreviated the CARB), the San Diego County Air Pollution Control District, the Environmental Protection Agency (EPA) of the U.S., and Maritime Administration (abbreviated MARAD) of U.S., which provided financial aid besides other resources.

The eWolf will provide services via advanced vessel control tech and first-in-class energy features while providing unparalleled quality, safety, and reliability that Crowley and the mariners have long been known for, mentioned James Fowler, senior V.P. and general manager of Crowley Shipping. The firm is thrilled to reach such a significant achievement for the company and the broader U.S. maritime industry via collaboration with the partners.

Vessel owners and operators are considering full and hybrid electric vessels as part of their efforts to lower emissions.
Crowley mentioned that the eWolf will be generating about 2.5 tons less quantity of diesel particulate matter, 178 tons less quantity of nitrogen oxide, and almost 3,100 metric tons less quantity of carbon dioxide over the first decade of operations – equivalent to eradicating gas worth 350,000 gallons from its use, per EPA calculations.

The battery system will be charged at an exclusively designed shoreside station with two Corvus Orca BOBs (battery on the vessel), the containerized version of Corvus Orca ESS. In 2021, Crowley announced its target to achieve net-zero emissions across scopes by 2050. The Jacksonville, Fla.-based firm estimates that it will lower the overall emissions by approximately 4.2 million metric tons of greenhouse gases yearly.
