LEAKAGE THROUGH CRACKS IN LNG TANKAGE
An experimental and theoretical investigation of leakage through fatigue indiced cracks in cylindrical test vessels was conducted. Test vessels were constructed from two aluminum alloys and 9% nickel steel. Experimental and theoretical leak rate vs pressure curves are presented and compared. The generally higher values of leak rate predicted by the theory are explained on the basis of the observed crack geometry. Recommendations are made for predicting leakage through fatigue cracks in tanks.
