        On 7^th of April,2023,one unit of 3680kW Hybrid ASD Tugboat “Yonggang Tuo 80”which is designed and built by our Company for Ningbo Oil Handling & Tug(Barge) Co.,Ltd was launched successfully. 

        The ship uses parallel Oil-Electric hybrid propulsion, that is, the superimposed drive of traditional diesel engine and battery-powered motor propulsion. In the hybrid mode, energy saving and emission reduction can be realized through the system's working condition optimization and intelligent energy scheduling, which can not only meet the requirement of optimal power output of the main engine, but also achieve the optimal energy consumption by superimposed lithium battery propulsion. When the tugboat enters the emission control area, it can switch to the pure battery mode for propulsion to realize zero emission in the control area. In the diesel propulsion mode, the excess power of the main engine can be fed back to the grid and charged by lithium batteries.

        The ship will become the first domestic "diesel-electric + battery" parallel hybrid tugboat, is filling the domestic gap, and also is our company's implementation of green、environmental protection and another landmark product of low carbon technology upgrade.
