Taking the riser of offshore platforms as the research object,the actual sea conditions and the actual structural characteristics of the riser are comprehensively considersed.The force coupling effect between multi-layer risers,as well as the force coupling effect between multi-layer risers and platforms are studied.Through finite element analysis software,a typical and representative numerical model of marine multi-layer risers is established to address the influence of pipe clamp position on the structure of the riser.Based on the position of pipe clamps,the structural strength and fatigue life of offshore pipe risers are analyzed and studied.Based on the analysis results,the installation position of pipe clamps is optimized to provide theoretical guidance for on-site operations and further provide scientific basis and safety guarantee for offshore engineering design and construction.
