Abstract

Global buckling for exposed HPHT (High Pressure / High Temperature) subsea pipelines is an important feature that needs to be considered during detailed design. The design of exposed pipelines will aim for; either to document that the pipeline will not buckle laterally, or, that the pipeline will buckle laterally and the post-buckling condition is acceptable. By safely triggering controlled buckles at predetermined locations, snaked lay design is often the preferred method to manage lateral buckling. Using finite elemet analyses, This paper discusses the effect of distance between two snaked-lays on lateral deflection, bending moment and strains. It was found that the distances between two snaked-lays have small effect on the max bending moment of the snaked-lay pipeline. For both sine curve and arc curve, with distances between two snaked-lays increasing, the resulting axial plastic strain is clearly enhanced.
