Abstract
A tank is provided that reduces sloshing pressures in the corner sections of a tank, such as an LNG membrane tank. The tank includes a sloshing impact reduction system placed in selected corner sections within the tank. The system serves as a slosh attenuation system, and reduces the severity of the corner geometry and improves the flow of fluids into the tank corner. In one embodiment, an impermeable structure is disposed in an internal corner section of the tank. The impermeable structure may be a triangular planar surface, or a non-planar structural surface. The non-planar structural surface may be a concave surface or other curved surface. In another arrangement, a permeable structure is placed in an internal corner section of the tank. Such a permeable structure would enable fluid to pass through the device, but would reduce the fluid velocities and accelerations via friction or eddies. The permeable structure may be either rigid or flexible.
