Crowley Maritime Corporation has announced it will be building and operating eWolf, the first all-electric powered harbour tugboat that can complete a job without expending a drop of fuel. 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 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 eTug will operate at the Port of San Diego’s Tenth Avenue Marine Terminal and will be operational by mid-2023.
