Patent ID: 7469651

Claim:
A tank for holding a cryogenic liquid under conditions such that the tank is subjected to environmental forces which induce motion of the tank and, in turn, sloshing of the liquid in the tank, comprising: at least two converging panels and a tank bulkhead defining an exposed corner section of the tank, wherein the exposed corner section is selected from intersections within the tank consisting of: a) an intersection of a top panel and a vertical side panel of the tank at the fore-bulkhead; b) an intersection of a top panel and a vertical side panel of the tank at the aft-bulkhead; c) an intersection of a top panel and an upper chamfer panel at the fore bulkhead; d) an intersection of a top panel and an upper chamfer panel at the aft bulkhead; e) an intersection of a vertical panel and an upper chamfer panel at the fore bulkhead; f) an intersection of a vertical panel and an upper chamfer panel at the aft bulkhead; and g) any combination of a) through f) above; and a slosh impact reduction system for attenuating fluid forces acting on the exposed corner section of the tank during sloshing, said slosh impact reduction system being positioned inside the tank, configured to cover at least the exposed corner section, and wherein the slosh impact reduction system is fitted to the at least two converging panels and the tank bulkhead defining the exposed corner section of the tank.
