CROWLEY TO BUILD FIRST US ALL-ELECTRIC HARBOUR TUG

CROWLEY TO BUILD FIRST US ALL-ELECTRIC HARBOUR TUG

Tuesday, July 13, 2021 

Crowley Maritime Corporation says it is to lead the next generation of industry sustainability by building and operating 'eWolf', believed to be the first all-electric powered harbour tugboat that can complete a job without itself expending any fuel.

Chairman and CEO Tom Crowley said: “The eWolf represents everything Crowley stands for: innovation, sustainability and performance. With this groundbreaking tug design, our team continues to embrace our role as leaders in the maritime industry while providing our customers with innovative and sustainable solutions done right."

The 70t bollard pull vessel is expected to save, over the first 10 years of its use, 178t of NOx, 2.5t of diesel particulate matter, and 3,100t of 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, utilising 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.

Port of San Diego Board of Port Commissioners Chairman Michael Zucchet said: “Crowley’s first-of-its-kind electric tugboat is a game changer. It checks all the boxes by providing environmental, economic, and operational benefits for our communities and maritime industry. We are proud to work with Crowley and couldn’t be more pleased the eWolf will operate exclusively on San Diego Bay.”

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 that customers demand.

“Our dedicated shipbuilding employees are proud to be working with Crowley to lead innovation with the construction of this first-of-its-kind tugboat,” said Garrett Rice, president, Master Boat Builders. “This vessel will set a standard in the US maritime industry for sustainability and performance, and its zero-emissions capability and autonomous technology will benefit the environment and the safety of mariners and vessels.”

The eTug is 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 US EPA and the US Maritime Administration, which all provided financial support and other resources.
