超大型导管架建造工艺探讨

Brief Introduction to Construction Technology of Ultra Large Jackets

随着海洋油气田向深水发展，超大型导管架在国内建造越来越多，论文主要以荔湾3．1导管架为例对超大型导管架的建造工艺进行介绍和探讨。荔湾3．1浅水平台导管架为南海深水天然气开发项目的中心平台导管架，气田位于南中国海东部，北偏西距香港约300kin。荔湾3．1导管架水深190m，重量约32000t。

With the development of offshore oil and gas fields to deep water area, more extra-large Jackets are built in China. With Liwan3-1 Jacket taken as an example, construction technology of extra large jackets is introduced and researched in this thesis. Li Wan 3-1 shallow water platform jacket belongs to Nanhai Deep Water Gas Field project. The field is located in the east part of South China Sea, about 300 km away from Hong Kong in north-west. Water depth of Li Wan 3-1 jacket is 190m and its weight is about 32000 tons.
