摘要
介绍国外在新型深水立管系统——钢悬链线立管关键技术方面的研究发展现状,论述浮体一、二阶运动对钢悬链线立管疲劳寿命的影响、浮体升沉运动对钢悬链线立管触地点疲劳寿命的影响;钢悬链线立管与海底相互作用机制的实验研究及结果;钢悬链线立管涡致振动与疲劳的研究现状。并简要论述钢悬链线立管触地点问题的研究结论。
A number of key techniques about Steel Catenary Risers, a new type of deepwater riser abroad, are introduced in the paper. The influence of the first-and second-order motion of floating structures on the fatigue life of steel catenary risers and the influence of heave motion of floating structures on fatigue life at the touchdown point （TDP） of steel catenary risers are expounded. A full-scale test on the riser-soil interaction and its influence on the riser are discussed. The state of with the art associated with VIV and VIV fatigue of steel catenary risers are also presented. The problems of the touchdown point of steel catenary risers are briefly discussed.
