Hybrid Tug Conversions
Conversion of existing tugs and workboats to hybrid propulsion based on the technology of the Carolyn Dorothy, the first hybrid tug.
Description
The Foss Rainier Shipyard built the world's first hybrid tug, the 23.8 m (78 ft) Dolphin-class Carolyn Dorothy, designed to retain power and maneuverability while reducing emissions, noise, fuel consumption and maintenance costs. The same technology can convert existing harbor tugs and other workboats to hybrid vessels.
