Flexible pipe handling system and method of using same
A system includes a drum assembly that includes a support bar having a first end and a second end, and a plurality of drum segments coupled to the support bar. The drum segments are movable between retracted and extended positions, and the drum assembly is configured to be disposed within an interior region of a coil of flexible pipe when the plurality of drum segments are in the retracted position. The system also includes a first containment flange coupled to the drum assembly at the first end, a second containment flange coupled to the drum assembly at the second end, a first coupling device configured to removably couple the first containment flange to the drum assembly, and a second coupling device configured to removably couple the second containment flange to the drum assembly. The first and second containment flanges are configured to contain the flexible pipe.
1. A system, comprising:
a drum assembly comprising:
a support bar; and
a drum segment coupled to the support bar, wherein the drum segment is movable between a retracted position and an extended position, and the drum assembly is configured to be disposed within an interior region of a coil of flexible pipe when the drum segment is in the retracted position;
a containment flange coupled to the drum assembly, wherein the containment flange is configured to contain the flexible pipe disposed on the drum assembly;
a coupling device configured to removably couple the containment flange to the drum assembly, wherein the coupling device comprises a latch coupled to the drum assembly and is configured to engage with a catch formed in the containment flange; and
a cam configured to disengage the latch from the catch.
2. The system of claim 1 , comprising a hinge that couples the cam to the latch, wherein the hinge is configured to enable the cam to rotate about the hinge with respect to the latch.
3. The system of claim 2 , wherein the cam comprises a handle to enable the cam to be rotated about the hinge.
4. The system of claim 1 , wherein the cam comprises a first surface and a second surface.
5. The system of claim 4 , wherein the drum assembly comprises:
an expandable spoke coupled to the support bar and the drum segment;
a spoke frame coupled to the expandable spoke; and
a plate coupled to the spoke frame.
6. The system of claim 5 , wherein the first surface of the cam is in contact with the plate when the cam is in a first position and the second surface of the cam is in contact with the plate when the cam is in a second position.
7. The system of claim 6 , wherein the latch is disengaged from the catch when the cam is in the first position and the latch is engaged with the catch when the cam is in the second position.
8. The system of claim 1 , comprising a spring mechanism configured to retain the latch engaged with the catch.
9. The system of claim 1 , wherein the catch comprises a plate disposed orthogonal to the containment flange and comprising an opening therein, and wherein the latch comprises a duck head-shaped portion configured to engage with the opening of the catch.
10. The system of claim 9 , wherein the duck head-shaped portion comprises an angled surface and a tip.
11. A method of engaging a drum assembly with a coil of flexible pipe, comprising:
disposing the drum assembly within an interior region of the coil of flexible pipe, the drum assembly comprising:
a support bar; and
a drum segment coupled to the support bar, wherein the drum segment is movable between a retracted position and an extended position, and the drum assembly is configured to be disposed within an interior region of a coil of flexible pipe when the drum segment is in the retracted position;
moving the drum segment from the retracted position to the extended position;
removably coupling a containment flange to the drum assembly via a coupling device by engaging a latch coupled to the drum assembly with a catch formed in the containment flange;
containing the flexible pipe disposed on the drum assembly using the containment flange;
disengaging the latch from the catch via a cam; and
uncoupling the containment flange from the drum assembly.
12. The method of claim 11 , comprising rotating the cam about a hinge that couples the cam to the latch.
13. The method of claim 11 , wherein the cam comprises a first surface and a second surface.
14. The method of claim 13 , wherein the drum assembly comprises:
an expandable spoke coupled to the support bar and the drum segment;
a spoke frame coupled to the expandable spoke; and
a plate coupled to the spoke frame.
15. The method of claim 14 , comprising:
contacting the first surface of the cam with the plate when the cam is in a first position; and
contacting the second surface of the cam with the plate when the cam is in a second position.
16. The method of claim 15 , comprising:
disengaging the latch from the catch when the cam is in the first position; and
engaging the latch with the catch when the cam is in the second position.
17. The method of claim 15 , comprising retaining the latch engaged with the catch using a spring mechanism.
18. The method of claim 15 , wherein the catch comprises a plate disposed orthogonal to the containment flange and comprising an opening therein, and wherein the latch comprises a duck head-shaped portion configured to engage with the opening of the catch.
19. The method of claim 18 , wherein the duck head-shaped portion comprises an angled surface and a tip.
