[Ocean New Energy] Sichuan’s first LNG-diesel dual-fuel dry cargo ship makes its maiden voyage in Luzhou
Thread Content
On the morning of August 15, accompanied by a long whistle, Sichuan's first LNG (liquefied natural gas)-diesel dual-fuel dry cargo ship "Jixiang 2022" slowly sailed out from Luzhou Jiangyun Shipyard, marking the beginning of the era of green energy ships in Sichuan. Sichuan has officially entered the "dual-fuel" era in the field of large-scale dry cargo ship construction. Equip the ship with a "green heart" and reduce pollutant emissions by 80%. The "Jixiang 2022" has a total length of 109.8 meters, a molded width of 16.26 meters, a molded depth of 6.6 meters, a design draft of 5.88 meters, a gross tonnage of 3898, and a reference cargo capacity of about 8000 tons. It is a large dry cargo ship. Unlike other large dry cargo ships, "Jixiang 2022" has a "green heart" - a 30 cubic meter marine LNG tank. Like a gasoline-electric hybrid vehicle, "Jixiang 2022" is a diesel and LNG (liquefied natural gas) dual-fuel hybrid ship. The maximum proportion of LNG in the ship can reach 80%. It is estimated that in gas mode, sailing at 23 kilometers per hour, the endurance of "Jixiang 2022" can reach 2,000 nautical miles, which is equivalent to the distance from Yunnan Shuifu Port to Shanghai, and only requires one LNG refueling. “When sailing against the current in the rapids section, diesel is used as power, while when sailing along the current or in other waters such as reservoir areas, clean energy compressed natural gas is used as power. ”“Luo Yongzhi, captain of "Jixiang 2022", said that the ship has an additional LNG gas control system. In order to become familiar with the performance and operation of the new system, all crew members received professional training before sailing. Jiang Wentao, a ship inspector at the Luzhou Navigation Administration Bureau, said that when LNG is used as ship fuel, compared with traditional ship fuel, it can reduce nearly 100% of sulfur oxide emissions, 85% of nitrogen oxide emissions, 20% of greenhouse gas emissions and nearly 80% of particulate matter emissions.
After preliminary research and development, the construction of "Jixiang 2022" began in January this year. With the joint efforts of shipyards, LNG manufacturers, diesel engine manufacturers and other parties, it took 7 months to complete the construction. The construction cost is about 16 million, which is about 3 million higher than building an ordinary ship. “Although the initial investment cost is high, it is estimated that each voyage can save 20% of fuel, which can be achieved over many years. * * Save costs. ”Chen Junjie, the legal representative of Luzhou Jinjixiang Shipping Co., Ltd., said that if "Jixiang 2022" can achieve the company's expected environmental and economic results after a one-year trial, it will consider continuing to build dual-fuel ships. At present, Luzhou City has listed the "Jixiang 2022" ship type as a standard ship type that is focused on encouraging development, giving priority to promotion, and has successively received orders for the construction of "green clean energy ships" from many shipping companies. In addition, in Zhaoba, Jiangyang District, in the Luzhou section of the Yangtze River, a "water LNG filling station" for refueling new energy ships has been planned and reserved with a dedicated shoreline, and construction is expected to start during the 14th Five-Year Plan.
Can make full use of Sichuan natural gas
“"Jixiang 2022" is a ship built by Luzhou Jiangyun Shipping Co., Ltd. for Luzhou Jinjixiang Shipping Co., Ltd. It mainly carries dry bulk cargo. Its navigation area is the A, B, C, J1, J2 navigation areas (sections) of the Yangtze River waters and the Three Gorges Reservoir area. Construction of the ship started in March this year, with a construction cost of approximately 17 million yuan. The hull is 110 meters long, 16 meters wide, has a designed draft of 5.7 meters, a designed gross tonnage of 3,908 tons, a full load displacement of 8,972 tons, a cargo capacity of 7,616 tons, and a speed of 18 kilometers per hour. It is expected to be put into operation in September this year.
It is reported that Luzhou has the best Yangtze River waterway in the province, and its shipbuilding technology has always been at the leading level in the province. Especially in the construction of large-scale and standardized ships, it has a lot of advanced experience and representative products. In addition to the 110-meter LNG diesel green energy standard ship currently under construction, in 2018, Luzhou Shipping Administration and Wuhan University of Technology jointly researched and developed a 105-meter Three Gorges ship lift standard container ship. From 2020 to 2021, 15 105-meter standard ships were built.
