The 82-foot vessel with 70 tonnes of bollard pull advances Crowley and 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 tonnes of nitrogen oxide (NOx), 2.5 tonnes of diesel particulate matter, and 3,100 metric tonnes 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 operate at the Port of San Diego’s Tenth Avenue Marine Terminal and will be operational by mid-2023.
