Horizontal pipe connection and length detection system

1. A tubular handling apparatus for a drilling system, comprising:

a first trough configured to receive at least a first tubular and a second tubular;

a second trough extending generally parallel to the first trough, the first and second troughs being generally horizontal, wherein the second trough is configured to receive the first and second tubulars from the first trough;

a first skate movable along the first trough and configured to engage a first end of the first tubular;

a second skate movable along the first trough and configured to engage a second end of the second tubular, wherein the first and second skates are configured to push a third end of the first tubular into engagement with a fourth end of the second tubular in the first trough;

a tongs configured to engage the first and second tubulars in the first trough and apply torque thereto; and

a V-door, wherein the second trough is aligned with the V-door and a well center.

2. The apparatus of claim 1 , further comprising a reader positioned proximal to the second trough and the v-door, wherein the reader is configured to acquire an identifier associated with the first tubular, the second tubular, or both.

3. A method for handling tubulars in a drilling system, the method comprising:

receiving a first tubular and a second tubular into a first trough;

moving the first and second tubulars together in the first trough using a first skate that engages a first end of the first tubular, and a second skate that engages a second end of the second tubular;

connecting together a third end of the first tubular and a fourth end of the second tubular by applying torque thereto;

determining a distance between the first and second skates after connecting together the first and second tubulars, wherein the distance corresponds to a length of the first and second tubulars after being connected together; and

transferring the first and second tubulars, after connecting the first and second tubulars together, to a second trough that is generally parallel to the first trough and is aligned with a well center.

4. The method of claim 3 , further comprising moving the first and second tubulars from the second trough to the well center.

5. The method of claim 4 , further comprising reading an identifier from the first tubular, the second tubular, or both while moving the first and second tubulars from the second trough to the well center.

6. The method of claim 5 , further comprising storing the identifier in association with the distance using a processor.

7. The method of claim 3 , wherein transferring the first and second tubulars comprises:

lifting the first and second tubulars out of the first trough using one or more kicking devices; and

rolling the first and second tubulars along a surface into the second trough.

8. A drilling system, comprising:

a drilling platform positioned over a well;

a V-door extending from the drilling platform, the drilling platform being configured to receive a tubular via the V-door; and

a catwalk positioned adjacent to the V-door, the V-door being configured to receive the tubular from the catwalk, the catwalk comprising:

a first trough configured to receive at least a first tubular and a second tubular;

a first skate movable along the first trough and configured to engage a first end of the first tubular;

a second skate movable along the first trough and configured to engage a second end of the second tubular, wherein the first and second skates are configured to push a third end of the first tubular into engagement with a fourth end of the second tubular in the first trough;

a tongs configured to engage the first and second tubulars in the first trough and apply torque thereto; and

a second trough extending generally parallel to the first trough, the second trough being configured to receive the first and second tubulars after the first and second tubulars are connected together in the first trough, wherein the second trough is aligned with the well.
