        On 20^th of December, 2023, 3680kW hybrid ASD tugboat "Yonggang Tuo 80" which is designed and built by our company for Ningbo Oil Handling&Tug(Barge) Co., Ltd was delivered successfully.

        The vessel uses the parallel oil-electric hybrid propulsion, that is, the superimposed drive of a traditional diesel engine and battery-powered motor. In the hybrid mode, energy saving and emission reduction can be achieved through the system working condition optimization and intelligent energy scheduling, it can not only meet the optimal power output requirements of the main engine, but also achieve the best energy consumption through the superimposed lithium battery propulsion. When the tugboat enters the emission control area, it can switch to the battery mode for propulsion, low noise, low vibration, comfortable and quiet, to achieve "zero fuel consumption, zero pollution and zero emissions" in the port. In the diesel propulsion mode, the excess power of the main engine can be fed back to the electric grid and the lithium battery for charging.

        The product fills the gap in the domestic "diesel-electric + battery" parallel hybrid tug, and is another landmark product that our company is iteratively upgrading in the direction of green, low-carbon, new energy for environmental protection and new drives.
