Arc Marine Technologies has initiated the engineering phase for the battery-electric conversion of the Harbor Sentinel, a 50-foot harbor tugboat operated by Pacific Maritime Group (PMG). The project marks a significant step toward decarbonizing port operations in Southern California.
Port of Long Beach’s Support Drives Innovation
The conversion is backed by funding from the Port of Long Beach through its Technology Advancement Program (TAP) and the SWIFT Program, both aimed at accelerating zero-emission marine solutions. This initiative aligns with the port’s broader commitment to reducing greenhouse gas emissions and improving air quality in the region.
Key Technical Considerations
The retrofit will replace the tug’s conventional diesel propulsion system with a high-voltage battery-electric powertrain, ensuring operational efficiency while maintaining the vessel’s performance in harbor operations. Arc’s expertise in marine electrification will guide the project, with a focus on reliability, safety, and compliance with maritime regulations.
Broader Implications for the Industry
This project underscores the growing trend of electrifying harbor tugs and auxiliary vessels, offering a scalable model for other operators in the U.S. and beyond. The successful implementation of the Harbor Sentinel conversion could serve as a benchmark for future zero-emission vessel projects, reinforcing the maritime industry’s shift toward sustainable propulsion technologies.
