Crowley Shipping and Shell Trading (US) Co. (STUSCO) recently began use of low carbon biofuel to power the Crowley tugboat Veteran, a ship assist and escort tug serving San Francisco Bay.
The fueling contract between the companies reflects their commitment to sustainable operations that decrease the carbon footprint and greenhouse gas impacts of maritime operations.
The Veteran, a 6,800-hp tug with a bollard pull of 182,000 lbs., received its first bunkering of 24,000 gals. of low carbon biofuel on March 9 in San Francisco, where Crowley has operated tugboats since 1906.
Veteran joins Crowley’s Vision/650-10, a U.S.-flagged, articulated tug-barge unit (ATB) that has continued to be bunkered with biofuel from STUSCO since December 2019. The ATB serves the U.S. and Canadian West Coast.
“Using biofuel continues Crowley’s commitment to enhancing the safety, sustainability and reliability of operations as stewards of the waters and communities that we serve,” Crowley’s John Ara, vice president, commercial logistics and customer interface, said in a statement announcing change. “Our customers benefit from cleaner, efficient services that reduce our impact on the air and greenhouse gases, helping lead our industry toward greater sustainability.”
The biofuel is lower in carbon intensity than conventional fuel, the use of which results in a reduction of greenhouse gas and air emissions such as carbon dioxide and Sulphur oxide. The biofuel runs the vessels’ main engines, generators and barge generators.
Crowley Shipping, a business unit of Crowley Maritime Corp., is the largest independent operator of petroleum tank vessels in the U.S., and an operator of ship assist and escort tugs serving domestic ports, company officials said.
