导管架平台拆除安全性分析

随着海洋石油工业的迅猛发展，废弃海洋平台的拆除问题已成为海洋工程界的研究热点，并得到世界各国该领域的广泛关注．在废弃导管架平台拆除过程中，保证其安全性是非常重要的．本文提出了用于分析导管架平台拆除安全性的危险指标Do和Ds，通过对Do和Ds的各列数据进行比较或对Do和Ds的各行数据做出折线图，可以很容易的得出最安全的桩基切割顺序。

Analyzing the safety of removal sequences for piles of an offshore jacket platform

An inevitable consequence of the development of the offshore petroleum industry is the eventual obsolescence of large offshore structures. Proper methods for removal of decommissioned offshore platforms are becoming an important topic that the oil and gas industry must pay increasing attention to. While removing sections from a decommissioned jacket platform, the stability of the remaining parts is critical. The jacket danger indices D _σ and D _s defined in this paper are very useful for analyzing the safety of any procedure planned for disassembling a jacket platform. The safest piles cutting sequence can be determined easily by comparing every column of D _σ and D _s or simply analyzing the figures of every row of D _σ and D _s .
