摘要

南海海域油气资源极其丰富，半潜式平台在该海域工作时常常面临着系泊失效这一重大危险情况。本文以一艘装配有悬链式系泊系统和DP-3动力定位系统的半潜式平台为研究对象，利用AQWA软件开展系泊失效前后半潜式平台运动性能研究。同时，借助于AQWA软件二次开发功能，将无模型自适应控制作为动力定位系统控制理论，以研究半潜式平台系泊失效后运动性能恢复。数值仿真模拟结果表明，采用无模型自适应控制作为动力定位系统控制理论的半潜式平台能很好地恢复系泊失效后的运动性能，有效地减小系泊失效带来的危害；基于偏格式动态线性化和全格式动态线性化的无模型自适应控制比基于紧格式动态线性化的无模型自适应控制能让半潜式平台更快地恢复运动性能。

Abstract

The South China Sea is rich in oil and gas resources, and semi-submersible platform often face the major danger of mooring failure when working in this area. In this paper, a semi-submersible platform equipped with catenary mooring system and DP-3 dynamic positioning system is taken as the research object, and study the motion performance of semi-submersible platform before and after mooring failure by using the software AQWA. At the same time, drawing help from the secondary development function of the software AQWA, model-free adaptive control is used as the control theory of dynamic positioning system to study the motion performance recovery of semi-submersible platform after mooring failure. Numerical simulation results show that the semi-submersible platform using model-free adaptive control as the dynamic positioning system control theory can recover the motion performance well after mooring failure and reduce the harm caused by mooring failure effectively. Model-free adaptive control based on partial form dynamic linearization and full form dynamic linearization can recover the motion performance of semi-submersible platform faster than model-free adaptive control based on compact form dynamic linearization.
