The tug will provide improved fuel efficiency and emissions," Erik Larsen, Rolls-Royce vice president for tug and fish in the Americas. “The key benefit operating these thrusters in a hybrid configuration is that it reduced the power requirement. Typically, a tug of this size would need a power output 2500kW. The hybrid arrangement allows operators to achieve the required bollard pull from a smaller engine. It provides greater operational flexibility."
Foss Maritime pioneered the use of hybrid tugs in 2008 with the Carolyn Dorthy, a Dolphin-class tractor tug augmented with lead-ac....
