Regu Ramoo, Director of Engineering at Altair Productdesign explains the work conducted with with Prof. Lamb of the University of Michigan to improve the design of a LNG tank system. Altair ProductDesign developed an innovative central interconnecting system that simultaneously mitigated hydrostatic loads while keeping the sloshing to a minimum. This design improvement retains all the advantages of the originally conceived idea of confining the liquid in a series curved shells so as to ensure that the structure is primarily loaded in a membrane mode rather than in a bending mode.
