| 摘 要： | 随着海洋油气资源开发逐渐走向深海,浮式结构物的定位能力越来越受到人们的重视。锚的泊辅助动力定位系统是将锚泊定位和动力定位相结合的一种新型海上定位系统。它具有安全性高、定位能力强、消耗功率小的特点。本文以某深水半潜式钻井平台为例,通过建立锚泊辅助动力定位时域模拟程序,分析平台在工作海况下的定位精度和功率消耗,并与相应海况下的动力定位进行比较。分析结果表明,该时域模拟程序能较为准确的地反映实际平台的定位情况。与动力定位相比,锚泊辅助动力定位能够取得更好的定位精度和较小的功率消耗,是更理想的定位方式。

| Abstract: | The higher demand of oil and gas has led to their exploitation and exploration in harsher and deeper waters. The capability to keep position with high accuracy of floating structures has been more and more concerned. Mooring assisted dynamic positioning system is a new positioning system combining mooring system with dynamic positioning system. It has the advantages of high safety, high positioning accuracy and low power consumption. With a certain deep water semi-submersible drilling platform as an example, this paper is dedicated to analyzing the positioning accuracy and power consumption by establishing a time-domain simulation program of positioning mooring system. Comparisons are made between dynamic positioning system and positioning mooring system. The comparisons show that the time-domain simulation can accurately reflect the practical positioning conditions of the platform. Compared with dynamic positioning, positioning mooring is a reasonable positioning method with better positioning accuracy and less power consumption. |
