锚泊定位系统是海洋工程装备的关键技术之一,因其具有较高的安全性、较强的定位能力、相对较低的经济成本等优点,因使用范围相当广泛,是海洋开发过程中必不可少的一项技术。本文针对南海岛礁复杂地形,设计一套适应极浅水下平台定位的锚泊系统,并计算分析其定位能力。考虑到复杂的地形,锚链采用非对称式布置,同时,为增加锚链与海底摩擦力,提高平台在偏离平衡位置后的回复力,在锚链上分散布置了许多重块。通过分析时域模拟的结果,验证该锚泊系统的可行性,为模型试验和极浅水环境下平台系泊系统的设计提供参考。
Mooring positioning system is one of the key technologies for marine structures, and it has high security, high positioning accuracy, relatively low economic cost, so it is widely used. It is an essential technology ocean development process. In this paper, designed a mooring system for a semi-submersible platform in ultra-shallow water of South China Sea reefs area and analyzed platform positioning accuracy. Considering the complex coastal ocean environment and ultra-shallow water, asymmetric arrangement mooring system is usually adopted. In order to increase bottom friction, chain is decorated a lot of weight.
