During the past 3 years Gaz Transport (GT) and McDonnell Douglas Corporation (MDC) have sponsored a study to develop improved methods for predicting the sloshing in prismatic LNG tanks. We have concentrated on fill ratios of above 90%, because it was originally thought that only low pressures would occur in this region, until shipboard experience in 1978 showed that pressures on the order of 10 bars could occur on the ceilings of the tanks even for fill ratios of 96% (Reference 1). These experiences led to the first model test programs at high fill ratios (References 1 and 2) conducted in 1979. However, the pressures predicted from these tests were no more than 2 to 3 bars. Thus it appeared that GT/MDC should try to develop a better understanding of the high fill ratio sloshing phenomena and to develop improved prediction methodology.
