Foss Maritime wins ports’ clean air technology award

San Pedro Bay Ports has given Foss Maritime an award for advancing hybrid tug technology that reduces greenhouse gasses, airborne particulates and pollution in all its forms.

Foss was chosen for a San Pedro Bay Ports Clean Air Action Plan air quality award (CAAP) in recognition of the XeroPoint hybrid retrofit system,  which was developed in partnership with Aspin Kemp and Associates of Owen Bay, Ont.  and underwent rigorous testing in Southern California waters. The award was given by a committee that includes representatives from the Long Beach and Los Angeles ports, the South Coast Air Quality Management District, CARB and the EPA.

Foss developed, built and operates the world’s first hybrid tug, Carolyn Dorothy, that has home-ported in San Pedro Bay for four years. Following the success of the first hybrid, Foss retrofitted a second tug, Campbell Foss, to hybrid technology. It has been in service in southern California since 2012 and was used in University of California-Riverside testing that is the basis for EPA’s hybrid retrofit system verification.

The UC-Riverside test found significant economic and environmental savings:

  • Fuel savings of roughly 30 percent;
  • 25 percent particulate matter reduction;
  • 30 percent reduction in nitrogen oxides produced during combustion;
  • 30 percent reduction in one of the prime greenhouse gases, carbon dioxide;
  • 35 percent reduction in carbon.


Foss plans to convert a third vessel, Alta June, to hybrid technology in 2014.
