Sloshing modeling in marine applications

The physical properties of sloshing in rectangular and prismatic tanks are discussed. Performance requirements for numerical methods are presented. The context is marine applications. A sloshing model based on a nonlinear modal theory analysis of two-dimensional nonlinear sloshing of an incompressible fluid with irrotational flow in a rectangular tank is outlined. This multi-modal method is the basis of a methodology used to calculate sloshing induced impact pressures. A procedure used to determine a statistical distribution of impact pressure for the case of sloshing in porismatic LNG tanksonborad a carrier operating in the North Sea is outlined.
