Security of Supply in a Gas‐Transmission System

Summary This paper attempts to quantify the relative vulnerability to pipeline breaks of different demand centres in a large‐scale gas‐transmission system. Demand centres remote from the points of supply are found to be the most vulnerable. The effects of siting liquefied natural gas storage at strategic points in the system are examined and it is discovered that quite modest storage proposals can increase the security of supply in the system threefold. No elaborate operational research technique is used and the analyses depend only on simple probability theory. The paper is an illustration of the use of simplifying assumptions to gain insight into a highly intricate problem.
