Internal Riser Inspection Device And Methods Of Using Same
US Patent:
2006026, Nov 23, 2006
Filed:
Jul 31, 2006
Appl. No.:
11/496160
Inventors:
Larry Harthorn - Conroe TX, US
Christopher Disher - Broussard LA, US
Christopher Disher - Broussard LA, US
International Classification:
E21B 47/00
US Classification:
073152570
Abstract:
An inspection apparatus includes an inspection unit that is lowered into vertically supported pipe filled with seawater. The apparatus includes a pipe weld location detector module carried by the inspection unit. The apparatus also includes a rotating time of flight diffusion (TOFD) module and a non-rotating wall thickness module carried by the inspection unit. The module includes a pair of rotatably mounted weld volume inspection transducers rotatable by an operator and adapted to inspect for and obtain data on weld volume defects. The TOFD module has a fluid carrier positioned within the TOFD module and contains an acoustic fluid. The non-rotating wall thickness module also contains an acoustic liquid and includes a plurality of fixedly mounted wall inspection transducers adapted to obtain data on wall thickness of a portion of the pipe.

Christopher Disher - Broussard LA, US
International Classification:
G01N027/72, G01R033/12
US Classification:
324/216000, 324/220000, 324/238000, 073/865800
Abstract:
A system for inspecting a pipe weld from within a pipe through use of magnetic particle imaging “MPI” includes an apparatus having a head unit that carries a wire wheel brush for cleaning an inspection area along an inner diameter of a pipe weld, and an MPI medium dispenser for spraying an MPI medium upon the inspection area, both controlled by an operator. The head unit also includes a video inspection device controlled by the operator and used for viewing at least portions of the inspection area after being sprayed with the MPI medium and when under the influence of a magnetic field to determine if the weld has any defects. The head unit is connected to a drive unit. The drive unit includes a frame having a longitudinal axis and mounted on a set of drive wheels, and a set of support wheels spaced axially from the drive wheels. A linear drive motor mounted to the frame and coupled to the drive wheels moves the head unit linearly along an interior of the pipe between weld inspection areas to allow the operator to locate and inspect the welds from within the pipe.
