摘要
海洋立管是海底管道和岸上、海上设施之间的连接管路或挠性软管,目前海洋石油天然气发展速度加快,海洋管道的口径也随之增大。文章主要讨论了立管安装的国内外发展现状,并论述了立管安装的三种主要方法:大型起重施工船+DSV、动力定位工程船+DSV和DSV单船立管安装方法,阐述了大口径立管安装的可行性。合理的选材及设计,不同海域寻求最优的安装方法是大口径立管安装技术的关键。
Marine riser is the connecting pipe or flexible hose between the submarine pipeline and the production equipment of onshore or offshore facilities.At present,with the gradual acceleration of the development of offshore oil and gas,the diameter of Marine pipeline is getting larger and larger.The development status of vertical pipe installation at home and abroad is discussed,and the three main methods of vertical pipe installation,which are large lifting construction ship &DSV,dynamic positioning engineering ship &DSV and DSV single-vessel vertical pipe installation method are proposed.
