Gisas Power

< 20 m

1000-1500 kWh

World’s 1st all-electric zero-emission tugboat now at work in Tuzla Aydınlı Bay, Istanbul. Electric motors are the perfect propulsion system for certain tugboats because they can generate a lot of power instantaneously and at low speeds. They also provide major savings on fuel, which is the second biggest expense for tugs after personnel. Maintenance expenses are also much lower with an electric propulsion system.
