    Abstract: It is a pig launcher (l) comprising a pig magazine (2), launcher mechanism (3) and a connector (7) being connectable to a fluid flow line. The pig magazine (2) is able to hold a number of pigs arranged side by side, control lines (4) being connected to the pig magazine in such a way that each control line (4) is able to provide control fluid to manipulate a pig. The pig launcher further comprises a pig selector (5) being able to receive source control fluid from one control fluid source line (9) and to channel the control fluid to one of a number of control lines (4) being connected to the pig selector, thereby being able to launch one of the number of pigs by means of the control fluid.

    Abstract: A compact subsea pig launcher (16) comprises a tubular magazine (42) for holding a plurality of pipeline pigs (10) in longitudinal succession ready for launching successively into a subsea pipeline. The magazine (42) is shaped to define at least one turn such as a coil around an upright axis. Thus, a series of pigs are stored in longitudinal succession along a path that is curved in plan view around the upright axis. During launching, at least one of the series of pigs is advanced along the path with angular movement around the upright axis.

    Abstract: A method and apparatus for cleaning a fluid conduit (112) in a hydrocarbon production installation. The method comprises providing a composite pipe (104) having a cleaning head (102) coupled to a first end, and introducing the first end of the composite pipe (104) and the cleaning head (102) into a fluid conduit (112) to be cleaned. Fluid is circulated between an annulus (124) between an interior wall of the fluid conduit (112) and the composite pipe (104), through a fluid circulation path defined by the cleaning head. The method comprises running the first end of the composite pipe (104) and the cleaning head (102) into the fluid conduit and cleaning at least one substance from the fluid conduit.A method comprising circulating a heavy fluid through the fluid circulation path to reduce the effective weight of the pipe in the fluid conduit, and another aspect relates to a method comprising generating at least one pressure pulse in fluid in the fluid circulation path while imparting a pulling force or a pushing force on the pipe.

    Abstract: A coupling device (20), a system (50,150,250), and a method for transferring a pig between inner tubes (12) of a jacketed pipes unit (11) (JPU) to clean the inner tubes (12). The coupling device (20) includes a mounting block (30). The mounting block (30) has at least first and second openings (33) extending through the mounting block (30). Each opening (33) is in fluid communication with a corresponding inner tube (12) when the mounting block (30) is mounted to the JPU (11). The coupling device (20) also has a looping conduit (40) connecting two of the inner tubes (12) in serial flow communication. The looping conduit (40) extends between a first loop end (41) mounted to the mounting block (30) about the first opening (33), and a second loop end (42) also mounted to the second surface (32) of the mounting block (30) about the second opening (33). The looping conduit (40) in use transfers the pig from one of the inner tubes (12) of the jacketed pipes unit (11) to another one of the inner tubes (12).

    Abstract: A pipeline pig includes a venturi and a modulating valve located rearward of the inlet side of the venturi. When the valve is in the open position, a predetermined maximum bypass flow is allowed through the venturi. The closed position allows a predetermined minimum bypass flow. The valve may be a poppet-style valve or a frusto-conical shaped stopper. The stopper has sufficient mass and/or aerodynamic drag to overcome the spring force holding the valve in the open position. When the pig stalls, the valve closes and the stopper chokes bypass flow through the venturi. When the pig starts running again, the valve opens as inertia forces the stopper away from the inlet side of the venturi. Also, as friction of the pig increases due to changes in the internal diameter of the pipeline or accumulation of debris ahead of the pig, increased airflow across the valve creates drag.

    Abstract translation: 管道猪包括位于文丘里管入口侧后方的文氏管和调节阀。 当阀门处于打开位置时,通过文丘里管允许预定的最大旁路流量。 关闭位置允许预定的最小旁路流量。 阀可以是提升阀或截头圆锥形止动器。 止动器具有足够的质量和/或空气动力学阻力以克服将阀保持在打开位置的弹簧力。 当猪失速时,阀关闭,止动器扼流器旁路流经文丘里管。 当猪再次开始运行时,阀门打开,因为惯性力使塞子远离文丘里管的入口侧。 此外,随着管道的内径变化或猪排前方的碎屑的积聚,猪的摩擦力增加,增加的气流横跨阀门产生阻力。
