基于数值模拟的浮式平台系泊研究

Design of Mooring Wharf for Floating Offshore Platform

浮式海洋平台作为一种较为新兴的海洋平台形式,具有工作水深大、运动性能好、抗恶劣环境能力强等诸多优点,一般用于深远海油气开发工程的应用。但由于浮式平台本身结构的复杂性,加之对该型平台的建造经验还很缺乏,国内海工行业在浮式生产领域存在着不少问题。其中,建造过程中的浮式平台码头系泊问题就是一项亟待解决的关键技术。基于此,采用数值模拟方法,对不同工况下的各方案中的系泊缆受力进行了详细计算。

As a relatively new type of offshore platform,floating offshore platform has many advantages,such as large working depth,good motion performance,strong ability to resist adverse environment and so on.It is generally used in deep and far sea oil and gas development projects.However,due to the complexity of the structure of the floating platform itself and the lack of experience in the construction of the platform,there are many problems in the field of floating production in the domestic offshore industry.Among them,the mooring problem of floating platform Wharf in the construction process is a key technology to be solved urgently.In this paper,empirical numerical simulation is used to calculate the mooring line forces under different conditions.
