摘要

利用TechnipFMC专有软件MLTSIM进行了炮塔/FPSO全耦合时域仿真。为了分析FPSO与其转塔之间的水动力相互作用和力学耦合效应,建立并分析了多体相互作用模型。在多体相互作用模型中,考虑了全耦合流体动力相互作用,并采用非线性弹簧和摩擦阻尼对轴承连接进行建模。将整体性能分析结果与模型试验结果(Kim et al.[1])进行了系统比较,并给出了转塔的水动力载荷和机械耦合载荷。

Time Domain Turret Load and Motion Analyses for a FPSO
Fully coupled time domain turret/FPSO simulations are conducted using TechnipFMC proprietary software MLTSIM. To analyze hydrodynamic interactions and mechanical coupling effects between an FPSO and its turret, a multi-body interaction model is developed and analyzed. In the multi-body interaction model, full coupled hydrodynamic interactions are considered, and the bearing connections are modeled with nonlinear springs and frictional damping. The global performance analysis results are systematically compared with model test results (Kim et al. [1]), and hydrodynamic loads and mechanical coupling loads on the turret are presented in this paper.
