Pioneers of innovative, high-powered ship assist tugboats, Crowley Maritime Corporation will lead the next generation of industry sustainability by building and operating eWolf, the first all-electric powered harbor tugboat that can complete a job without expending a drop of fuel, according to the company's release.
Crowley will build and operate first all electric tug in U.S.
The 82-foot vessel with 70 tons of bollard pull advances Crowley and the maritime industry’s efforts toward sustainability and decarbonization. Over the first 10 years of its use, the operation of the new eTug will reduce 178 tons of nitrogen oxide (NOx), 2.5 tons of diesel particulate matter, and 3,100 metric tons of carbon dioxide (CO2) versus a conventional tug. The electric tug will replace one that consumes more than 30,000 gallons of diesel per year. The eTug will operate at the Port of San Diego’s Tenth Avenue Marine Terminal and will be operational by mid-2023.
The eTug will be built by Master Boat Builders in Coden, Ala., utilizing the design and on-site construction management by Crowley Engineering Services and its recently integrated Jensen Maritime naval architecture and marine engineering group. The eTug’s battery system will be charged at a specially designed, shoreside station developed with Cochran Marine.
The eWolf will feature a design that allows the vessel to operate fully electric with full performance capabilities – and zero carbon emissions. The eTug will feature a fully integrated electrical package provided by ABB. With 360-degree visibility, the eTug will also feature ABB’s artificial intelligence technology (AI) to increase safety and efficiency for mariners and provide sustainable performance with the reliability customers demand.
The eTug will be a result of a partnership among Crowley, the San Diego County Air Pollution Control District, the California Air Resources Board, the Port of San Diego, the U.S. Environmental Protection Agency and the U.S. Maritime Administration, which all provided financial support and other resources.
