作为常规地面管架或栈桥管廊方案的替代,LNG接收站卸料管道专用隧道是一种全新的技术解决方案,具有许多独特之处,为此,介绍了目前世界上仅有的两条卸料管道专用隧道--美国Dominion Cove Point LNG接收站和日本东京瓦斯Ohgishima LNG接收站卸料管道专用隧道的情况,并以广东省某地处于前期可行性研究阶段的LNG项目为例,分析了国内第一条LNG卸料管道专用隧道工程的内部系统相关设计和研究情况,提出了该类型隧道内系统设计应着重考虑的设计特点:横断面的基本形状;高等级安全性的保障;合适的操作和维护设施;连续监控系统的设置.该研究成果对更为广泛的低温管道专用隧道内部系统的设计和研究具有借鉴和参考意义.

As an alternative scheme for pipe-racks or trench on the ground, the LNG unloading pipeline tunnel with many unique features is a brand-new solution during the construction of a LNG receiving terminal. This paper hereby introduces two LNG unloading pipeline tunnels - Dominion Cove Point LNG Receiving Terminal in the USA and Ohgishima LNG Terminal in Tokyo, Japan - only two of this kind in the world. The paper also introduces the relevant research and design of the inner system of the Chinese first LNG unloading piping tunnel in a LNG terminal of Guangdong, which is still in front-end feasibility study. Finally, this paper brings forward four special points necessary to be emphasized, including the basic configuration of transect, high-grade security control, reasonable operation and maintenance prevention, the setting of continuous monitoring system. This paper will contribute to the study and design of the inner systems of cryogenic pipeline tunnels.
