Inflatable pipe drum systems and methods

1. A pipe drum system comprising a drum body, wherein:

the drum body is configured to be disposed within an interior channel of a pipe coil that is formed from a flexible pipe comprising tubing that defines a pipe bore and a fluid conduit within an annulus of the tubing; and

the drum body comprises:

a drum core implemented with substantially fixed dimensions; and

a fluid bladder layer implemented circumferentially around the drum core, wherein the pipe drum system is configured to:

maintain the fluid bladder layer in a first state to enable the drum body to be inserted into the interior channel of the pipe coil after the pipe coil is formed; and

increase inflation of the fluid bladder layer from the first state to a second state to enable an outer surface of the drum body to push against an inner surface of the pipe coil to facilitate supporting the pipe coil.

2. The pipe drum system of claim 1 , wherein the fluid bladder layer of the drum body comprises a fluid bladder helically wrapped in an axial direction along the drum core of the drum body.

3. The pipe drum system of claim 1 , wherein the fluid bladder layer of the drum body comprises:

a first fluid bladder wrapped circumferentially around the drum core; and

a second fluid bladder wrapped circumferentially around the drum core such that the second fluid bladder is adjacent to the first fluid bladder in an axial direction along the drum core.

4. The pipe drum system of claim 3 , wherein the pipe drum system is configured to supply more actuation fluid to the first fluid bladder than the second fluid bladder to facilitate accommodating nonuniformity in shape of the interior channel of the pipe coil along the axial direction.

5. The pipe drum system of claim 1 , wherein the fluid bladder layer of the drum body comprises a plurality of fluid bladders arranged in a honeycomb or quilted arrangement.

6. The pipe drum system of claim 1 , comprising:

one or more fluid sources fluidly coupled to the fluid bladder layer of the drum body via one or more external fluid conduits; and

a control sub-system communicatively coupled to the one or more fluid sources, wherein the control sub-system is configured to selectively instruct the one or more fluid sources to supply actuation fluid to the fluid bladder layer, to extract actuation fluid from the fluid bladder layer, or both.

7. The pipe drum system of claim 1 , wherein the drum body comprises another fluid bladder layer implemented circumferentially around the fluid bladder layer, wherein the pipe drum system is configured to:

maintain the other fluid bladder layer in the first state to enable the drum body to be inserted into the interior channel of the pipe coil after the pipe coil is formed; and

increase inflation of the other fluid bladder layer from the first state to the second state to enable the outer surface of the drum body to push against the inner surface of the pipe coil to facilitate supporting the pipe coil.

8. The pipe drum system of claim 7 , wherein the pipe drum system is configured to increase inflation of the fluid bladder layer from the first state to the second state while maintaining inflation of the other fluid bladder layer in the second state when the drum body is disposed within another pipe coil that has a smaller inner surface diameter than the pipe coil.

9. A method of implementing a pipe drum system, comprising:

implementing a drum core of a drum body in the pipe drum system that is to be disposed within an interior channel of a pipe coil such that the drum core has substantially fixed dimensions;

securing a drum shaft to the drum core of the drum body such that the drum shaft extends out from the drum core; and

securing a plurality of fluid bladders circumferentially around the drum core of the drum body to enable:

the drum body to be inserted into the interior channel of the pipe coil at least in part by maintaining the plurality of fluid bladders in a deflated state; and

the drum body to be secured to the pipe coil at least in part by transitioning the plurality of fluid bladders from the deflated state to an inflated state to enable flexible pipe to be deployed from the pipe coil at least in part by rotating the drum body about the drum shaft.

10. The method of claim 9 , wherein securing the plurality of fluid bladders circumferentially around the drum core comprises:

wrapping a first fluid bladder around the drum core to form a first fluid bladder loop; and

wrapping a second fluid bladder around the drum core to form a second fluid bladder loop that is adjacent to the first fluid bladder loop in an axial direction along the drum core.

11. The method of claim 10 , comprising:

fluidly coupling the first fluid bladder to one or more fluid sources in the pipe drum system via a first one or more external fluid conduits; and

fluidly coupling the second fluid bladder to the one or more fluid sources in the pipe drum system via a second one or more external fluid conduits.

12. The method of claim 9 , wherein securing the plurality of fluid bladders circumferentially around the drum core comprises securing the plurality of fluid bladders circumferentially around the drum core in a honeycomb or quilted arrangement.

13. The method of claim 9 , wherein securing the plurality of fluid bladders circumferentially around the drum core comprises:

securing a first fluid bladder directly on the drum core; and

securing a second fluid bladder over the first fluid bladder.

14. The method of claim 9 , wherein implementing the drum core of the drum body comprises:

forming a rim, wherein securing the plurality of fluid bladders circumferentially around the drum core comprises securing the plurality of fluid bladders circumferentially around the rim of the drum core;

forming a base, wherein securing the drum shaft to the drum core comprises securing the drum shaft to the base of the drum core; and

securing a plurality of spokes between the rim and the base.

15. A drum body comprising:

a drum core implemented to have a substantially fixed geometry;

a drum shaft that extends out from the drum core to enable flexible pipe to be deployed from a pipe coil that is secured to the drum body at least in part by rotating the drum body about the drum shaft; and

a plurality of fluid bladders secured circumferentially around the drum core, wherein the plurality of fluid bladders is configured to:

contract an outer surface diameter of the drum body inwardly as the plurality of fluid bladders is transitioned from an inflated state to a deflated state to enable the drum body to be inserted into an interior channel of the pipe coil; and

expand the outer surface diameter of the drum body outwardly as the plurality of fluid bladders is transitioned from the deflated state to the inflated state to facilitate securing the drum body to the pipe coil.

16. The drum body of claim 15 , wherein the drum core comprises:

a rim, wherein the plurality of fluid bladders is secured circumferentially around the rim of the drum core;

a base, wherein the drum shaft extends out from the base; and

a plurality of spokes secured between the rim and the base of the drum core.

17. The drum body of claim 15 , wherein the plurality of fluid bladders comprises:

a first fluid bladder that is wrapped circumferentially around the drum body to form a first fluid bladder loop; and

a second fluid bladder that is wrapped circumferentially around the drum body to form a second fluid bladder loop that is adjacent to the first fluid bladder loop in an axial direction along the drum core.

18. The drum body of claim 15 , wherein the plurality of fluid bladders comprises:

a first fluid bladder secured directly on the drum body; and

a second fluid bladder secured over the first fluid bladder.
