Abstract

Abstract: The design of a tension mooring system plays a key role in the overall layout of deepwater semi-submersible production platforms. To explore the influence of the connection point position between the mooring line and hull, anchor position, and mooring line configuration on the maximum mooring line tension and platform maximum displacement, a finite element model of the tensioned mooring system for semi-submersible platform was established using numerical analysis software in this research. An automatic simulation program was developed through data interface integration to generate a sample set. Subsequently, the backpropagation neural network combined with genetic algorithm was employed to optimize design parameters of the mooring system, thus deriving the optimal mooring system configuration. The results show that compared with the pre-optimization data, the maximum mooring line tension is reduced by 10.04 %, and the platform maximum displacement is reduced by 25.29 % . The prediction error of the algorithm is controlled within 10 % . The combination of numerical simulation with the neural network-genetic algorithm provides engineering guidance for the mooring system design of deep-water semi-submersible production platform.

摘要： 张紧式系泊系统设计是深水半潜式生产平台总体布置的关键点之一。为研究系泊缆与船体连接点位置、锚点位置和系泊缆构型对系泊缆最大张力与平台最大位移的影响规律,基于数值分析软件建立半潜式平台张紧式系泊系统有限元模型,并通过接入数据接口构建自动仿真程序得到样本集,然后结合反向传播神经网络-遗传算法对系泊系统设计参数进行优化,得到最优的系泊系统参数配置。研究结果表明,通过系泊系统优化前后数据进行对比,系泊缆最大张力减小10.04%,平台最大位移量减小25.29%。该算法所预测误差控制均在10%以内。将数值模拟与神经网络-遗传算法相结合,可为深水半潜式生产平台系泊系统的设计提供工程指导。
