LNG投资运营方案及经济性分析

LNG Investment Operation Scheme and Economic Analysis

探讨了与现有沿海LNG接收站合作建设储罐,通过管输、槽车及小型LNG船舶分销的投资运营方案,并与传统的LNG经营模式进行经济性对比,并对LNG槽车运输及小型LNG船舶运输方式的经济性进行了对比分析。在选定的运输距离及建设规模条件下,提出的LNG投资运营方案均摊总成本为0.447元/m3,而传统LNG经营模式的均摊总成本为0.82元/m3;自行建设沿海LNG储罐等设施可以规避窗口期费用及部分费用,经济性有较大提高。在LNG槽车和小型LNG船舶运输距离均为550 km的情况下:当小型LNG船舶周转量为19.57×104 t/a时,两种运输方式经济性相同;当运输量小于19.57×104 t/a时,槽车运输的经济性优于船运。在沿海储罐的年周转量为200×104 t/a,LNG槽车运输量为40×104 t/a,内河小型LNG船运输量为50×104 t/a的情况下,当运输距离大于252 km时,小型LNG船舶运输的经济性具有显著的优势。

The investment operation scheme of cooperation with existing coastal LNG terminal to build storage tanks and distribution of through pipeline transportation,tank trucks and small LNG ships is discussed,and economically compared with the conventional LNG business model.The economy of two transportation modes,LNG tank trucks and small LNG ship transportation is compared and analyzed.In the case of a fixed transportation distance and a certain construction scale,the average total cost of the proposed scheme is 0.447 yuan/m 3,while that of conventional LNG business model is 0.82 yuan/m 3.Self-construction of facilities such as coastal LNG storage tanks can avoid the cost and part of the window period,and the economy has been greatly improved.Under the condition that the transportation distance of LNG tank trucks and small LNG ship transportation is both fixed at 550 km,when the annual transportation volume of small LNG ships is 19.57×10 4 t,the two modes of transportation are economically equivalent;when the annual transportation volume is less than 19.57×10 4 t,the economy of tank trucks transportation is better than that of shipping.Under the condition that the annual turnover of coastal LNG storage tanks is 200×10 4 tons,and the annual transportation volumes of LNG tank trucks and inland river small LNG ships are 40×10 4 tons and 50×10 4 tons,respectively,the transportation of small LNG ships has a remarkable economic advantage as the transportation distance exceeds 252 km.
