Crowley Maritime Corp., Jacksonville, Fla., says it 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 using an ounce of fuel. “The eWolf represents everything Crowley stands for - innovation, sustainability and performance,” company Chairman/CEO Tom Crowley said in a media release. The 82-foot tug, with 70 tons of bollard pull, advances Crowley efforts of sustainability and decarbonization, Crowley said. Over the first decade, operation of the 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, Crowley officials said. The eTug will replace one that consumes more than 30,000 gallons of diesel per year. The eWolf will operate out of San Diego. It is to be built by Master Boat Builders of Coden, Ala., utilizing the design and on-site construction management by Crowley Engineering Services.
