PYROTECHNIC SIMULATION OF THE PRESSURES DUE TO WAVE ACTION--APPLICATION TO THE PROBLEM OF SLOSHING IN (LNG) TANKERS
The risk of accidents occurring on sea routes increases with the growth of LNG tonnage carried. The nature of the gases carried deserved particular attention. Should a methane carrier of 200,0900 m capacity accidentally discharge its load, a release of energy equivalent to a Type A nuclear charge would result. Reference is made to an incident that occurred in the LNG carrier Arctic Tokyo which was due to a small escape of gas across the membrane of the insulation bulkhead of a cargo tank. This membrane had been distorted by the sloshing effect of the methane in the tank during rough weather. Tests carried out by Technigaz and Bureau Veritas to evaluate the critical pressure wave are mentioned. The pyrotechnic research and study group of D.C.A.N., Toulon, have developed a pyrotechnic device to generate an impulse comparable to a nuclear shock wave. The tests, which were carried out on 1/10th scale to reduce the risks involved, are briefly described. These tests provided a realistic simulation of the sudden stresses due to sloshing in the tank and wave effect on the hull.
