The first one includes flat steel panels and lightweight core filled in the panels' gap, which is called laminated sandwich structures. The second one includes flat steel panels, steel corrugated core...

... be reduced to minimize the use of resin rope. In this study, the corrugation of the inner side of the hull is measured, and the offset table of the corrugation is used to calculate the deformation of the LNG tank hull. To solve the optimization problem, an objective function with constraints...

Wave impact tests enabled to gain much knowledge on the physics of liquid impacts including the influence of the compressibility of ullage gas and the interaction between waves and the protuberances on the wall like the corrugations of MarkIII containment system...

... ABSTRACT: MarkIII is one of the containment systems designed by GTT for LNG storage or transportation. It features a corrugated stainless steel membrane which modifies locally the flow of LNG in the tanks of LNG carriers, hence modifies the loads during sloshing impacts. The interactions...

...’ are not Froude-similar when the compressibility of the gas is not scaled. The one-dimensional model of Bagnold (1939) is used to correct the loading process ‘compression of entrapped air’ measured at scale 1:6, resulting in a similar load to the one measured at scale 1:1. horizontal corrugation wave...
