结合南海海域条件对传统式张力腿平台进行整体设计,计算平台所受各种环境荷载的大小,并采用拟静力分析法分析此平台的非线性运动响应,考虑平台水平漂移和下沉的非线性关系以及张力腿预张力、横截面面积、就位长度和立柱横截面面积等参数对平台运动响应的影响。
The general design of a classic tension leg platform (TLP) was completed in light of the environmental condition of South China Sea and interrelated criterion. Various environmental loads acting upon the TLP were calculated and the quasi-static movement response of the TLP was analyzed considering the nonlinear relations between horizontal drift and vertical subsidence. The inflence of TLP's tension, cross-sections, lengths and column's cross-sections upon the movement response of TLP were studied.
