液化天然气船到港接卸流程与优化

运输是LNG产业链中的一个重要环节,直接影响供应的稳定性与消费的经济性。船舶运输以其运距长、运力大、安全性高等特点一直在LNG运输中占据主导地位。结合大宗LNG国际贸易的特点,参考国内外相关标准与接收站操作规程,对LNG船到港接卸工艺、流程进行详细论述。根据目前在役的LNG船型,特别是国内已接船型的特点,对船、岸兼容性与各环节工艺设备选型与操作等进行了分析。针对LNG船在港卸货过程中存在的安全、技术及操作等问题,提出了切实可行的解决办法与优化措施,细化并完善了LNG接卸程序,可为国内外船运LNG到港接卸提供参考。

Harbor unloading process and optimization of LNG ship

Transportation is one of the important links in the LNG industry chain,which directly affects the stability of gas supply and the economy of gas consumption.Shipping has taken a leading position in the LNG transportation by its long distance,large capacity,high safety,and other characteristics.Combined with the characteristics of the bulk LNG international trade and with reference to domestic and international relevant standards and receiving station operating procedures,LNG ship receiving and unloading technology and process are discussed in detail.According to characteristics of different LNG ships in service and especially received domestic ships,ship-harbor compatibility,selection and operation of process equipment in various aspects,etc.are analyzed.For the safety,technology,operation,and other problems of LNG shipping in the unloading process,practical solutions and optimization measures are proposed and LNG receiving and unloading procedure is carefully detailed and improved,which can provide a reference to domestic and international LNG ship receiving and unloading.
