Crowley has received the eWolf, the first all-electric harbour tugboat in the US, showcasing a major step in sustainable maritime operations. Designed by Crowley and built by Master Boat Builders, the eWolf will operate with zero emissions in the Port of San Diego starting in spring 2024. The tugboat is part of a collaborative project aimed at reducing environmental impact, involving various government and environmental partners. The tug will generate 178 tons less of nitrogen oxide (NOx), 2.5 tons less of diesel particulate matter and 3,100 metric tons less of carbon dioxide (CO2) over the first 10 years of its operations – the equivalent of removing 350,000 gallons of gas from use, according to EPA calculations. The vessel uses ABB’s innovative, integrated electrical propulsion system.
