摘要： A apparatus and method of using the apparatus for removing a blockage in a subsea pipeline without retrieval of the pipeline to the surface. The apparatus components include a hot tap saddle, a drill assembly, a fluid blaster assembly and a support frame. The hot tap saddle component has a first portion and a second portion, with the first and second portions being configured to clampingly engage in a sealing relationship to the subsea pipeline. The first portion of the saddle includes a first and second opening with the first opening extending generally upwardly and configured for connecting to a drill assembly and the second opening being positioned generally at an angle to the first opening and configured for connecting to a fluid blaster assembly. The fluid blaster assembly including a nozzle, a hose and a high pressure pump with the fluid blaster assembly being contained within a pressure vessel. The fluid blaster assembly is configured for mounting to the second opening of the hot tap saddle component. The support frame assembly is configured for gripping and supporting the subsea pipeline on the sea floor while the fluid blaster assembly operates to remove a blockage in the subsea pipeline with the pipeline being under pressure and without severing the pipeline.
摘要翻译：一种使用该装置去除海底管道中的堵塞而不将管道返回到地面的装置和方法。设备组件包括热水龙头，钻头组件，流体喷射器组件和支撑框架。热丝addle部件具有第一部分和第二部分，其中第一和第二部分构造成夹紧地与海底管道密封接合。鞍座的第一部分包括第一和第二开口，其中第一开口大致向上延伸并且构造成用于连接到钻头组件，并且第二开口通常以与第一开口成一定角度定位并且被构造成用于连接到流体喷射器组件。包括喷嘴，软管和具有流体喷射器组件的高压泵的流体喷射器组件包含在压力容器内。流体喷射器组件构造成用于安装到热水龙头鞍部件的第二开口。支撑框架组件构造成用于在海底上夹持和支撑海底管道，同时流体喷射器组件操作以在管道处于压力下并且不断开管道的情况下移除海底管道中的堵塞。
