Caroline Dorothy” & “Campbell Foss”

Foss Maritime (founded in 1889) is the largest tug and towing concern on the west coast of the United States. For their Carolyn Dorothy and Campbell Foss we provided new 150 kWh battery packs (Lithium Polymer) in their existing tugs, thus creating the first hybrid tugs on the US west coast.
