Abstract:

Jumper spools with connectors are widely used in subsea devices installations during offshore oil and gas fields exploration, and can be operated by horizontal tie-in system or vertical tie-in system. Mechanical collet connector, hydraulic collet connector, and clamp connector are the most common selection in subsea jumper spools connection. Mechanical collet connector is compactive, and leaves no hydraulic components subsea, but connector actuation tools is needed in operation. Hydraulic collet connector is operated directly from the ROV, and with no need for a dedicated actuating tool. Clamp connectors consist of a two piece segmented clamp design and are particularly well suited for larger bore, lower pressure horizontal connection applications. Different connector types and different tie-in manners demand different installation process and different tools. Diameter, tie-in manner, and tools should be considered carefully in the connetor  selection of jumper spool.

摘要： 跨接管两端携带连接器, 广泛用于海洋油气田水下设备之间的连接, 可以采用水平或者垂直连接方式。常用的水下跨接管连接器主要是机械式套筒连接器、液压式套筒连接器, 以及夹钳连接器。机械式套筒连接器结构紧凑, 安装完毕, 海底不留任何液压部件, 但是安装时需要采用接头作动工具。液压式套筒连接器集成了全部液压操作功能, 不再需要其他作动工具。夹钳连接器采用分离式闭合夹紧设计, 特别适合于大口径、低压管线和立管的水平跨接。不同的连接器, 以及相同的连接器在不同位置的安装, 其安装流程不同、需要的配套工具也不相同。跨接管连接器选型原则主要考虑因素包括管径、连接方式和安装工具。
