Development of Advanced Natural Gas Storage by Steel-Lined Rock Cavern System

3^rdReport : Experimental Result and Evaluation of Air-Tight Steel Liner in Test Cavern

Abstract

During the developing of next-generation type High-Pressure Natural Gas Strage System, we intended to store the gas in the rock cavern. In order to develop a steel-line rock cavern stroge system, we have designed and constructed a small scale model tank to carry out demonstration tests.
For assessment of adequacy and viability of design technology, the demonstration tests were consisted of Pressure Test, Air Tight Test and Repeated Long-term Loading Test at 20MPa and Pressure Test at 30MPa. Report #2 of this paper describes the outlines and test results of the demonstration test and the assessment results on the adequacy of design technology for the steel liner, which is a steel lining, and the viability of the system based upon the subsequent analysis.
