Recently, China's first green and intelligent Three Gorges ship-type bulk carrier "Lihang Yujian No. 1" was jointly developed by Houpu Clean Energy Group Co., Ltd.(hereinafter referred to as HQHP) was put into operation and successfully completed its maiden voyage.
"Lihang Yujian No. 1" is the first Three Gorges ship-type ship propelled by oil-gas-electric hybrid power among the ships passing the locks of the Three Gorges of the Yangtze River. Compared with the traditional Three Gorges 130 ship-type ship, it has a strong advantage. During sailing, it can intelligently switch to a greener power mode according to the sailing status, resulting in lower energy consumption and higher efficiency. When launching into the water, the main engine drives the propeller, and at the same time, the generator charges the lithium battery; during the flood season, the main engine and the electric motor jointly drive the propeller; the ship lock can be powered by electric propulsion for low-speed navigation to achieve zero emissions. It is estimated that 80 tons of fuel can be saved every year, and the carbon dioxide emission rate will drop by more than 30%.
One of the power systems of "Lihang Yujian No. 1" adopts HQHP's marine FGSS, and the core components such as LNG storage tanks, heat exchangers, and double-wall pipes are all independently developed and designed by HQHP.
The LNG heat exchange method in the system adopts direct heat exchange with river water. Considering the different water temperatures in different seasons in the Yangtze River section, the heat exchanger adopts a special structural design for efficient heat exchange and daily cleaning and maintenance. Within the range of 30°C, the continuous and stable air supply volume and air supply pressure are guaranteed to realize the smooth operation of the system. In addition, also utilize BOG to achieve an economical operation mode that reduces BOG emissions and better helps ships save energy and reduce emissions.
