外海有限条件下深水平台施工关键技术

Key Technologies for Construction of Deepwater Platform under Limited Offshore Conditions

本文在对以往外海条件下作业平台设计、施工调研的基础上,结合依托项目施工特点,提出在外海有限作业窗口期施工条件下,只有装配化整体式平台结构才能满足现场施工需求,才能实现水上平台快速化施工。本文介绍了本项目装配式平台的设计及施工工艺,提出了装配式平台节点连接技术——高性能混凝土灌注技术,探讨了外海有限作业窗口期施工条件下装配式平台的设计及施工技术控制要点。

By investigating the design and construction of offshore operating platform,combined with the project characteristics,it is found that only assembled integrated platform can meet field construction needs and achieve rapid construction of offshore platform during offshore operation window period.the design and construction technology of the assembled platform are introduced,including the joint technology,i.e.high-performance concrete pouring technique.In addition,further discussion is carried out for the control points for the design and construction technology of the assembled platform during offshore operation window period.
