Crowley Maritime Corporation, pioneers of innovative, high-performance ship support tugs, will lead the next generation of sustainability in the industry by building and operating eWolf. This first all-electric harbor tugboat can get the job done without consuming any fuel.


“The eWolf represents everything Crowley stands for: innovation, sustainability and performance. With this groundbreaking tug design, our team continues to fulfill its role as a leader in the marine industry, providing our customers with innovative and sustainable solutions done right.” said the company’s chairman and CEO, Tom Crowley.


The 82-foot, 70-ton bollard pull vessel advances Crowley and the maritime industry’s sustainability and decarbonization efforts. In the first ten years of its use, operating the new e-tractor saves 178 tons of nitrogen oxides (NOx), 2.5 tons of diesel particles and 3,100 tons of carbon dioxide (CO2) compared to a conventional tractor. The electric tow tractor will replace one that uses more than 30,000 gallons of diesel annually. The eTug will be deployed 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, Alabama, using on-site design and construction supervision from Crowley Engineering Services and its recently integrated naval architecture and marine engineering group, Jensen Maritime. The eTug’s battery system is charged at a purpose-built shore station developed with Cochran Marine.


“Crowley’s first electric tug of its kind is a game changer. It ticks all the boxes by providing environmental, economic and operational benefits for our communities and the maritime industry,” said Chair Michael Zucchet of the Port of San Diego Board of Port Commissioners. “We are proud to be working with Crowley and couldn’t be happier that the eWolf will be used exclusively on the San Diego Bay.”


The eWolf will feature a design that allows the ship to operate fully electrically at full capacity – with zero CO2 emissions. The eTug will feature a fully integrated electrical package from ABB. With 360-degree visibility, the eTug will also be equipped with ABB’s artificial intelligence (AI) to increase safety and efficiency for seafarers and provide sustained performance with the reliability customers demand.


“Our dedicated shipbuilding workforce is proud to work with Crowley to drive innovation by building this first tugboat of its kind,” said Garrett Rice, President of Master Boat Builders. “This ship will set a standard for sustainability and performance in the U.S. shipping industry, and its zero-emission capability and autonomous technology will benefit the environment and the safety of seafarers and ships.”


The eTug will be the result of a partnership between 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, all of whom have provided financial support and others Resources.
