摘要

摘要: 作为一种改良型的钢悬链线立管（steel catenary riser，SCR），钢质懒波型立管（steel lazywave riser, SLWR）在深水油气开发中的应用越来越广泛.SLWR的立管形态在其设计中至关重要.在海流作用下，SLWR的立管形态会发生相当大的变化.利用非线性大变形梁理论建立了海流作用下的SLWR立管模型，能更好地反应其真实的力学形态.通过数值方法得到了本模型的数值解，并详细分析了海流对立管形态的影响.本模型对SLWR的动态分析提供了重要的参考作用.

Abstract: As a kind of improved SCR, the steel lazy-wave riser (SLWR) gained more and more application in the development of deepwater oil and gas field. The configuration of the SLWR is of great significance in its design process. Under ocean current, the configuration and mechanical parameters of the SLWR vary a lot. A model of multipoint boundary-value differential equations based on the nonlinear large deformation beam theory was proposed to simulate the responses of the SLWR under ocean current. Numerical program was built to get the approximate solution to the theoretical model and parametric analysis was conducted to study the influences of different ocean currents on the configuration of the SLWR. Results show that the axial tension force at the touchdown point of the SLWR increases distinctly with the rise of the ocean current velocity, which deserves full consideration in the configuration design of the SLWR. The proposed model makes an important reference for the performance analysis of the deepwater SLWR.
