- 针对冀东南堡1号人工岛和3号人工岛之间的海底混输管道和输水管道悬空的实际情况,通过对四种海底管道悬空治理方法进行比选以及现场实践,最终选用了"抛石回填、高点开挖、管顶覆盖"方案,成功地进行了悬空治理。文章介绍了冀东NP1-3D/NP1-1D海底管道悬空治理方案的实施过程。
According to the free spanning situation of the submarine multiphase pipeline and water pipeline between No. 1 artificial island and No.3 artificial island of Nanpu Oilfield in Jidong, four free spanning control methods were compared. With the help of field experience, the method of “rock dumping, high point excavation， sand and stone covering” was chosen and used successively to control the free spanning. The implementation of the pipeline free spanning control method is described in this paper.2011,S1(S1): 80-82 收稿日期：2011-8-10分类号：TE973作者简介：付春丽（1982- ），女，山东青岛人，助理工程师，2009年毕业于中国石油大学（华东），主要从事海底管道建设及预投产等相关的安装设计工作。参考文献：
