1. A pipe handling system comprising:
an inboard bore plug assembly configured to facilitate plugging an inboard end of a pipe bore in a flexible pipe that is formed into a pipe coil, wherein the inboard bore plug assembly comprises: a first inflatable plug having:
a first inflatable bladder that defines a first fluid cavity and a first inflation port opening that opens to the first fluid cavity;
a first inflation fluid port secured within the first inflation port opening such that the first inflation fluid port opens to the first fluid cavity; and
a first plug securement mechanism, wherein the first plug securement mechanism comprises a first threaded fastener configured to be secured in a first fastener opening formed through tubing of the flexible pipe such that the first threaded fastener extends into the pipe bore of the flexible pipe behind the first inflatable plug of the inboard bore plug assembly; and

an outboard bore plug assembly configured to facilitate plugging an outboard end of the pipe bore in the flexible pipe, wherein the outboard bore plug assembly comprises a second inflatable plug having:
a second inflatable bladder that defines a second fluid cavity, a second inflation port opening that opens to the second fluid cavity, and a bore port opening that extends through the second inflatable bladder; and
a second inflation fluid port secured within the second inflation port opening such that the second inflation fluid port opens to the second fluid cavity;
a bore fluid port secured in the bore port opening such that the bore fluid port extends through the second inflatable plug to enable the pipe bore in the flexible pipe to be pressurized to an elevated fluid pressure at least while the flexible pipe is being unwound from the pipe coil; and
a second plug securement mechanism, wherein the second plug securement mechanism comprises a second threaded fastener configured to be secured in a second fastener opening formed through the tubing of the flexible pipe such that the second threaded fastener extends into the pipe bore of the flexible pipe behind the second inflatable plug of the outboard bore plug assembly.
