Abstract
A truck mounted portable electromagnetic inspection (EMI) machine assembly is disclosed. The truck mounted portable EMI assembly includes a portable EMI machine having an input port coupled to a scanning tunnel and adapted to receive a tubular for passing through the scanning tunnel, the scanning tunnel comprising an excitation coil configured to induce an eddy current in a surface of the tubular passing through the scanning tunnel, and an output port coupled to the scanning tunnel and adapted to allow the tubular to exit from the scanning tunnel, and a mechanical turntable adapted to mount the portable EMI machine on a truck and adjust an orientation of the portable EMI machine with respect to the truck. The mechanical turntable includes an upper base and a lower base coupled together.

A truck mounted portable electromagnetic inspection (EMI) machine assembly, comprising:
- a portable EMI machine comprising:
- an input port coupled to a scanning tunnel and adapted to receive a tubular for passing through the scanning tunnel;
- the scanning tunnel comprising an excitation coil configured to induce an eddy current in a surface of the tubular passing through the scanning tunnel;
- and
- an output port coupled to the scanning tunnel and adapted to allow the tubular to exit from the scanning tunnel;
- and
- a mechanical turntable comprising:
- an upper base having a circular shaped protrusion extending from a bottom side of the upper base;
- and
- a lower base having a recess formed on a top side of the lower base to receive the protrusion when the upper base and lower base are coupled together to form the mechanical turn table,
- wherein the mechanical turntable is adapted to:
- mount the portable EMI machine on a truck;
- and
- adjust an orientation of the portable EMI machine with respect to the truck.
A truck equipped with a portable electromagnetic inspection (EMI) machine, comprising:
- a flat bed adapted to mount the portable EMI machine;
- the portable EMI machine comprising:
- an input port coupled to a scanning tunnel and adapted to receive a tubular for passing through the scanning tunnel;
- the scanning tunnel comprising an excitation coil configured to induce an eddy current in a surface of the tubular passing through the scanning tunnel;
- and
- an output port coupled to the scanning tunnel and adapted to allow the tubular to exit from the scanning tunnel;
- and
- a mechanical turntable comprising:
- an upper base having a circular shaped protrusion extending from a bottom side of the upper base;
- and
- a lower base having a recess formed on a top side of the lower base to receive the protrusion when the upper base and lower base are coupled together to form the mechanical turn table,
- wherein the mechanical turntable is adapted to:
- mount the portable EMI machine on the flat bed;
- and
- adjust an orientation of the portable EMI machine with respect to the truck.
A method for performing an operation of a wellsite, comprising:
- dispatching, to the wellsite prior to performing the operation, a truck equipped with a portable electromagnetic inspection (EMI) machine, comprising:
- a flat bed adapted to mount the portable EMI machine;
- the portable EMI machine comprising:
- an input port coupled to a scanning tunnel and adapted to receive a tubular for passing through the scanning tunnel;
- the scanning tunnel comprising an excitation coil configured to induce an eddy current in a surface of the tubular passing through the scanning tunnel;
- and
- an output port coupled to the scanning tunnel and adapted to allow the tubular to exit from the scanning tunnel;
- and
- a mechanical turntable adapted to:
- mount the portable EMI machine on the flat bed;
- and
- adjust an orientation of the portable EMI machine with respect to the truck;
- performing EMI to detect a defect of the tubular, wherein the tubular with the defect is rejected from being use in the operation of the wellsite;
- and
- facilitating, by at least rejecting the tubular with the defect, the operation of the wellsite.
