Overview

• Eight tugs valued at about $20 million each are on order, with the first four committed for delivery before the end of 2027.
• Each vessel will use over 4,000 horsepower of electric propulsion and a 6 MWh battery buffer in an electric-first hybrid setup with a diesel generator for backup.
• The design supports megawatt-class shore charging, with Arc planning MCS installations at the Port of Los Angeles.
• Arc will provide vertically integrated electric powertrains, while Curtin Maritime and Snow & Co. will handle design and construction on the U.S. West Coast.
• The companies say the program will lower fuel and maintenance costs, boost reliability, and prove commercial viability versus diesel without relying on grants.
