STRUCTURAL DESIGN CRITERIA FOR THE SAFE AND ECONOMICAL TRANSPORTATION OF LIQUEFIED NATURAL GAS

Major problems in the engineering design of ship structures have emerged from the requirements for specialized vessels to transport liquefied natural gas (LNG). Transporting the largest volumes of cryogenic cargo ever carried, our vessels will ply but a single trade route, and they must meet strict draft limitations and stringent delivery rate requirements. They must be built and operated to provide an extra margin of safety and a long service life. They must meet or exceed all regulatory requirements. It has been necessary to develop new designs for structures, and to utilize the latest analytical techniques in order to evaluate and optimize the designs. The techniques include fleet modeling, three dimensional finite analysis and model basin tests. Quality control is important, especially in design definition and review, material selection and control, and inspection. Although there has been substantial progess in the design of structures for LNG ships, there is still considerable work to be done.
