摘要: 为了解海洋石油支持船(Offshore Support Vessel-OSV)抛锚作业过程中,系泊缆和工作缆的缆型、张力变化以及抛锚作业对锚作船的影响,提出了一种OSV抛锚作业的建模方法。采用MMG(Ship Manoeuvring Mathematical Model Group)建模思想,建立了六自由度拖船运动数学模型,通过水下缆索任一微元段的受力平衡条件导出各微元段的动力学微分方程,建立了拖缆模型在此基础上考虑耦合边界条件,建立了船-缆-锚-缆系统的运动数学模型, 并采用龙格库塔方法对船舶运动积分求解,采用差分法对拖缆运动进行求解。仿真结果表明该模型可为制定抛锚控制策略提供参考依据,并对OSV模拟器开发提供理论基础。

Abstract: In order to understand the configurations of mooring line and working wire, tension variation at release point of working wire and the influence of the offshore support vessel during anchoring operation, a mathematical models of OSV anchoring operation was established. According to the MMG (Ship Manoeuvring Mathematical Model Group) ship motion mathematical modeling theory, a 6dof ship motion mathematical model was built. And a 6dof cable motion mathematical model was established with finite difference method. A coupling ship-cable-anchor-cable system model was established. The system motion simulations were carried out, and the results indicate that the model can be used to determine the control strategy of the systems during operation, and provide theory support for offshore oil ship simulator development.

Key words: offshore support vessel, mooring line, working wire, ship motion mathematical model, finite difference method
