Crowley tugboats used for ship assistance and escort operations in the Port of Los Angeles have begun using newly-installed shore-side electrical power when not on the job in an effort to cut fuel consumption and reduce carbon dioxide emissions. Previously, the tugs tied up at the dock needed to run their generators to provide electrical power. Crowley and the Port of Los Angeles recently completed this initiative, known as cold ironing, at Berth 86. The port paid to run electrical power to the dock, and Crowley purchased and installed the electrical connections to the boats and transformers to decrease the voltage. Crowley expects to conserve fuel used by the generators daily in its Los Angeles operations, and consequently reduce carbon dioxide emissions by more than 486,180 pounds in the first year.
