摘要: 深水钻井平台移位主要有使用自身推进器自航、由拖轮拖带(纯拖)、由拖轮拖带且同时使用推进器协助(混拖)三种方式。以海洋石油981为例,就该平台的自航、纯拖及混拖三种移位工况,就三种移位方式存在的风险隐患及经济效率分别进行分析。分析结果表明,自航移位方式经济性最好,混拖次之;混拖所需移位时间最短,自航和纯拖所需时间基本相同。

Abstract: Deepwater semi-submersible drilling units normally move between well locations by sailing using self-propulsion, towing by tug boat, or combination of self-propulsion and towing. Comparison and analysis of these three approaches are carried out in the aspects of risk tolerance and economic efficiency using HYSY981 as an example. The results show that: self-propulsion is the most economical way of the three, combination towing is the second, but the combination towing could save a lot of time, and the time of moving the platform by self-propulsion and that by towing are almost the same to each other.
