DESIGN OF LNG PIPING SUPPORTED ON A FLEXIBLE WHARF
At the LNG facility at Port Nikishi, Alaska, the loading lines had to be designed for large axial movements due to pipe contraction and wharf movements. Piping consists of 2000 ft of 24 in. stainless steel pipes insulated with polyurethane rigid foam. Thermal contraction of the pipe for the 1380 ft of wharf was as much as 46 in., while lateral deflection for any wharf support tube was as much as 24 in. The line was anchored at the shore end and provided with expansion joints at the loading end; supports slide back and forth under the pipe on teflon slide plates. To accomodate lateral deflection, the number of guides was minimized in keeping with the maximum free column length of pipe that could be tolerated within critical buckling limits.
