Abstract
A method of repairing a flexible pipe within a carrier pipe. The method then increases a first area of a first hole in the carrier pipe. The method then bends a first layer of the flexible pipe around a second hole in the first layer. The method then patches a third hole in a second layer of the flexible pipe.
Claims20
A pipeline comprising:
- a carrier pipe, wherein a first hole is present in the carrier pipe;
- a flexible pipe disposed within a bore of the carrier pipe, wherein:
- a second hole aligned with the first hole in the carrier pipe is present in an outer layer of the flexible pipe;
- a third hole aligned with the first hole in the carrier pipe is present in a middle layer of the flexible pipe;
- and
- a fourth hole aligned with the first hole in the carrier pipe is present in an inner layer of the flexible pipe;
- and
- a hole seal secured over the fourth hole in the inner layer of the flexible pipe, wherein:
- material in the middle layer of the flexible pipe around the third hole in the middle layer is bent back to increase an initial area of the third hole to facilitate securing the hole seal over the fourth hole in the inner layer;
- and
- an initial area of the first hole in the carrier pipe is increased to enable the material in the middle layer of the flexible pipe to be bent back.

A method of repairing a flexible pipe that is disposed within a bore of a carrier pipe, comprising:
- increasing an area of a first hole in the carrier pipe to provide access to the flexible pipe, wherein the first hole in the carrier pipe is aligned with a second hole formed in an outer layer of the flexible pipe, a third hole formed in a middle layer of the flexible pipe, and a fourth hole formed in an inner layer of the flexible pipe;
- patching the fourth hole in the inner layer of the flexible pipe via the first hole in the carrier pipe, the second hole in the outer layer of the flexible pipe, and the third hole in the middle layer of the flexible pipe;
- implementing a first annulus seal in an annulus defined between an inner surface of the carrier pipe and the outer layer of the flexible pipe such that the first annulus seal is upstream of the fourth hole in the inner layer of the flexible pipe;
- implementing a second annulus seal in the annulus defined between the inner surface of the carrier pipe and the outer layer of the flexible pipe such that the second annulus seal is downstream of the fourth hole in the inner layer of the flexible pipe;
- securing a seal body to the carrier pipe to cover the first hole in the carrier pipe;
- and
- flowing liquid material into the annulus defined between the inner surface of the carrier pipe and the outer layer of the flexible pipe using the seal body to facilitate implementing solid material in the annulus between the first annulus seal and the second annulus seal.

A pipeline repair system, comprising:
- a hole seal configured to be sealed over a first hole formed through an inner layer of a flexible pipe, wherein:
- the flexible pipe is disposed within a bore of a carrier pipe;
- and
- the first hole in the inner layer of the flexible pipe is aligned with a second hole formed through a middle layer of the flexible pipe, a third hole formed through an outer layer of the flexible pipe, and a fourth hole formed through the carrier pipe;
- a first annulus seal configured to be implemented in an annulus defined between an inner surface of the carrier pipe and the outer layer of the flexible pipe such that the first annulus seal is upstream of the first hole in the inner layer of the flexible pipe;
- a second annulus seal configured to be implemented in the annulus defined between the inner surface of the carrier pipe and the outer layer of the flexible pipe such that the second annulus seal is downstream of the first hole in the inner layer of the flexible pipe;
- and
- a seal body configured to be secured to the carrier pipe to cover the fourth hole in the carrier pipe, wherein the seal body comprises:
- a first port configured to enable fluid material to be flowed into the annulus defined between the inner surface of the carrier pipe and the outer layer of the flexible pipe;
- and
- a second port configured to enable air displaced by the fluid material to be released from the annulus.
