摘要： Compliant leak detection system. The system includes structure adapted to support at least two rows of leak detection leaves, each leak detection leaf supported by an arm pivotally attached to the structure and urged outwardly by a torsion spring into contact with a pipe wall so as to adjust for changes in pipe diameter. The leak detection leaf includes a rigid support and a flexible member such that suction from a leak will cause the flexible member to contact the pipe wall and put a drag force on the structure. An axial force transmitting drum measures the drag force to indicate presence of a leak.

摘要： Methods of remotely facilitating the transition between hydrotesting and dewatering of a subsea pipeline include a control unit of a subsea valve actuation system determining when hydrotesting of the pipeline has been completed and autonomously allowing fluid flow out of the pipeline at the receiving end thereof without the involvement of an external source at the surface, or a UV, at the pig receiving end of the pipeline to allow dewatering the pipeline from the launch end of the pipeline.

摘要： The system utilizes conductivity equipment as well as a camera, pressure sensor, and acoustic hydrophone within a probe deployed via cable into a pipe to be inspected. The probe completes an electric circuit back to ground when the probe is adjacent a defect through which electric currents can pass, thus producing varying electric current. The camera, incorporated into the electric probe, is utilized for both inspection and navigation through the pipe by providing a close-circuit video data feed. The pressure sensor detects alterations in the pressure and flow field of the fluidic region in the area of a leak. The acoustic hydrophone listens for the sound leaks in pressurize pipes may create. The inspection device is tethered to a cable and inserted a measured distance into the pipeline, typically with the pipeline under pressure, via a launch tube. Multi-sensor data versus pipe position is thus obtained.

摘要： The pipeline leak detector travels through a pipeline passively due to the flow of liquid through the pipeline. The device includes leading and trailing rings shaped to produce hydrodynamic resistance in order for the device to be carried through the pipeline. Wheels are provided about each ring, with at least one wheel having an odometer to measure distance traveled through the pipe. The rings are joined by a plurality of axially oriented connecting rods. A plurality of sensing elements extend between the rings. Each sensing element has a thin laminate of a piezoelectric film sandwiched between two electrically conductive layers, with an electrically insulating coating on the outside of each conductive layer. One of the rings includes microelectronic circuitry for data acquisition and storage.

摘要： Leak detection system. The system locates leaks in a pipeline that includes RFID tags deployed at known locations along the pipeline. A pair of bodies tethered to one another a fixed distance apart travels along the pipeline. Each of the bodies is supported for movement substantially along the centerline of the pipeline and each body includes a sensor responsive to sound or pressure variations generated by a leak. Signals are correlated to identify the existence of a leak. Each body also includes an RFID reader for reading the RFID tags in the pipeline. At least one of the bodies includes a power supply and/or electronics that are adapted to correlate signals from sensor on each body to determine the location of a leak within the pipeline.

摘要： A device and a method for pipeline leakage detection. A pipeline leak detector travels through the bore of a pipeline, applies a test pressure to a fluid contained within the pipeline, and measures the resultant rate of change of pressure in the pipeline by using back extrapolation of the test data to determine an initial pressure drop rate. The degree of leakage at a given position in the pipeline is then determined from the rate of change of pressure in the pipeline.

摘要： Normally closed valve for controlling flow of fluid material through a straight, non-tapered conduit has resilient elastomeric seal attached to the perimeters of two axially aligned rigid end plates. Elasticity of elastomeric seal draws end plates together while radially expanding so as to engage and seal against the inner wall of conduit. Valve may be opened by axially separating the two opposing end plates using a locally actuated displacer mechanism attached to one of the end plates, causing the elastomeric seal to radially contract and the valve to open.
