Abstract

The cable handling apparatus includes a trolley beam, where the trolley beam is adapted to allow a cable trolley to slide thereon and an articulating arm. The articulating arm is hingedly coupled to the trolley beam, and the articulating arm is hingedly coupled to a piece of wellsite equipment. The articulating arm is repositionable between a retracted position and an extended position.

Claims

1. A cable handling apparatus comprising:

a trolley beam, the trolley beam adapted to allow a cable trolley to slide thereon;

an articulating arm, the articulating arm hingedly coupled to the trolley beam, the articulating arm hingedly coupled to a piece of wellsite equipment, the articulating arm repositionable between a retracted position and an extended position.

2. The cable handling apparatus of claim 1, wherein the articulating arm is hingedly coupled to the piece of wellsite equipment by a hinge assembly, the hinge assembly comprising a hinge and a pinning assembly, the pinning assembly positioned to retain the articulating arm in at least one of the retracted position and the extended position.

3. The cable handling apparatus of claim 1, wherein the trolley beam comprises an I-beam.

4. The cable handling apparatus of claim 1, wherein two or more cable trolleys are positioned on the trolley beam.

5. The cable handling apparatus of claim 4, wherein a cable is coupled to each of the cable trolleys such that the cable festoons below the cable trolleys as the cable trolleys move closer together.

6. The cable handling apparatus of claim 5, wherein each cable trolley of the two or more cable trolleys is coupled to at least one adjacent cable trolley by a spacing cable, the spacing cable having a length shorter than the length of the cable between the adjacent cable trolleys.

7. The cable handling apparatus of claim 1, wherein the piece of wellsite equipment comprises a frame and the articulating arm is hingedly coupled to the frame of the piece of wellsite equipment.

8. The cable handling apparatus of claim 1, wherein the piece of wellsite equipment comprises one of an equipment house, tank, mud pump skid, or substructure box framing.

9. A beam trolley festoon system comprising:

a first trolley beam, the first trolley beam adapted to allow a cable trolley to slide thereon;

a first articulating arm, the first articulating arm hingedly coupled to the first trolley beam, the first articulating arm hingedly coupled to a first piece of wellsite equipment, the first articulating arm repositionable between a retracted position and an extended position;

a second trolley beam, the second trolley beam adapted to allow the cable trolley to slide thereon;

a second articulating arm, the second articulating arm hingedly coupled to the second trolley beam, the second articulating arm hingedly coupled to a second piece of wellsite equipment, the second articulating arm repositionable between a retracted position and an extended position;

the first trolley beam and second trolley beam selectively coupleable when in the extended position.

10. The beam trolley festoon system of claim 9, wherein the first and second pieces of wellsite equipment are positioned in a wellsite substantially aligned such that, when the first and second trolley beams are positioned in the extended position, the first and second trolley beams are substantially aligned and are coupleable to form a continuous trolley beam assembly such that the cable trolley may slide freely from the first trolley beam to the second trolley beam.

11. The beam trolley festoon system of claim 9, wherein the first and second articulating arms are hingedly coupled to the first and second pieces of wellsite equipment by a first and second hinge assemblies respectively, the first and second hinge assemblies each comprising a hinge and a pinning assembly, the pinning assembly positioned to retain the first and second articulating arms in at least one of the retracted position and the extended position.

12. The beam trolley festoon system of claim 9, wherein the first and second trolley beams comprise an I-beam.

13. The beam trolley festoon system of claim 10, wherein two or more cable trolleys are positioned on the continuous trolley beam.

14. The beam trolley festoon system of claim 13, wherein a cable is coupled to each of the cable trolleys such that the cable festoons below the cable trolleys as the cable trolleys move closer together.

15. The beam trolley festoon system of claim 13, wherein each cable trolley of the two or more cable trolleys is coupled to at least one adjacent cable trolley by a spacing cable, the spacing cable having a length shorter than the length of the cable between the adjacent cable trolleys.

16. The beam trolley festoon system of claim 9, wherein the first piece of wellsite equipment comprises a frame and the first articulating arm is hingedly coupled to the frame of the first piece of wellsite equipment.

17. The beam trolley festoon system of claim 9, wherein the first piece of wellsite equipment comprises one of an equipment house, tank, mud pump skid, or substructure box framing

18. A method for rigging up a beam trolley festoon system, the method comprising:

positioning a first piece of wellsite equipment at a wellsite, the first piece of wellsite equipment including;

a first trolley beam, the first trolley beam adapted to allow a cable trolley to slide thereon;

a first articulating arm, the first articulating arm hingedly coupled to the first trolley beam, the first articulating arm hingedly coupled to the first piece of wellsite equipment, the first articulating arm repositionable between a retracted position and an extended position;

positioning a second piece of wellsite equipment at the wellsite generally aligned with and near the first piece of wellsite equipment, the second piece of wellsite equipment including;

a second trolley beam, the second trolley beam adapted to allow the cable trolley to slide thereon;

a second articulating arm, the second articulating arm hingedly coupled to the second trolley beam, the second articulating arm hingedly coupled to the second piece of wellsite equipment, the second articulating arm repositionable between a retracted position and an extended position;

positioning the first and second trolley beams into the extended position;

coupling the first and second trolley beams.

19. The method of claim 18, further comprising:

pinning with a pinning assembly at least one of the first or second articulating arms in the extended position.

20. The method of claim 18, further comprising:

decoupling the first and second trolley beams;

positioning the first trolley beam into the retracted position;

transporting the first piece of wellsite equipment to another location.
