The 82-foot vessel with 70 tons of bollard pull nudges the maritime industry’s efforts toward sustainability and decarbonisation. 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) compared to a conventional tug. It will replace a tug that currently consumes more than 30,000 gallons of diesel per year and will operate at the Port of San Diego’s Tenth Avenue Marine Terminal. It will be operational by mid-2023.
“The eWolf represents everything Crowley stands for: innovation, sustainability and performance” said Chairman and CEO Tom Crowley. “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 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.
The eWolf will feature a design that allows the vessel to operate fully electric with full performance capabilities – and zero carbon emissions. It 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 US Environmental Protection Agency and the US Maritime Administration, which all provided financial support and other resources.
