    摘要:

    300米级深水导管架在我国南海陆坡区域应用广泛,但是由于导管架总高度高、舱容大,导致扶正过程中出现姿态和钩头力发生剧烈变化,影响扶正过程的安全平稳。为了解决常规扶正方案应用于深水导管架的弊端,迫切需要优化注水放空系统和扶正设计。本文以我国南海某深水导管架为研究对象,提出了系统管线腿内布置和增加压力表的带压注水方案,并通过数值模拟完成带压注水的扶正过程设计。导管架海上操作按照设计扶正方案进行,通过监测舱室压力反推注水量,实现精准控制。海上实测数据和数值模拟结果接近,且相对常规扶正方案实现了对舱室注水量的控制,导管架扶正过程姿态稳定。本文的研究表明,带压注水扶正设计可以满足深水导管架扶正精准控制的目标,降低导管架海上安装作业风险,相关技术可进一步推广至常规深水导管架。

    Abstract:

    300 meter deep water jacket is widely used in the South China Sea, however, due to the large overall height and compartment capacity, there are significant changes in jacket upending status and hook force during offshore installation, which affects the safety and stability of the upending process. In order to solve this problem, it is urgent to optimize the flooding and venting system and upending design. This paper takes a deep-water jacket as an example, introduces the flooding and venting system line arrangement and controlled upending scheme, and completes upending process numerical simulation. During offshore operation, the jacket is up-righted according to the upending and flooding sequence, and precise control is achieved by monitoring the compartment pressure to reverse the flooded water amount. The measured data and numerical simulation results are close. Compared with conventional upending plan, the control of compartment flooded water is achieved, and the jacket status during jacket upending process is stable. The research in this paper indicates that the controlled upending design can meet the goal of jacket upending precise control, reduce the risk of offshore installation, and related technologies can be further promoted to conventional jackets.
