SYSTEM FOR MONITORING HEAT-PROOF SECTION OF LNG SHIP CARGO TANK

摘要

PROBLEM TO BE SOLVED: To more precisely monitor an abnormal state.;SOLUTION: A system is provided with a first pressure gauge 23 which measures a primary space pressure of primary spaces 7-1 to 7-5, a second pressure gauge 23 which measures a secondary space pressure of secondary spaces 8-1 to 8-5, a third pressure gauge 23 which measures atmospheric pressure, and a measuring computer 21 which discriminates an abnormal state on the basis of the primary space pressure, the secondary space pressure, atmospheric pressure. The abnormal state is quickly found by the measuring computer 21.;COPYRIGHT: (C)2002,JPO
