Abstract

A method includes providing a length of pipeline that has a housing defining a central bore extending the length of the pipe and a space formed within the housing and extending the length of the pipe. At least one condition within the space is continuously monitored within the space to detect in real time if a change in the housing occurs.

First claim

What is claimed is:

1. A method, comprising:
providing a length of pipe, the pipe comprising:
a housing, wherein the housing includes
an inner layer having an inner surface defining a central bore extending the length of the pipe,
an outer layer having an outer surface, and
one or more intermediate layers disposed between the inner layer and the outer layer,

and a conduit formed within a section of the one or more intermediate layers and extending the length of the pipe; and

continuously monitoring at least one condition within the conduit to detect in real time if a change in the housing occurs, wherein the continuous monitoring is performed using a plurality of sensors disposed along the length of the conduit.

2. The method of claim 1 , wherein the conduit comprises a predetermined amount of gas, and the at least one condition being continuously monitored comprises pressure.

3. The method of claim 2 , wherein a plurality of pressure transducers continuously monitor the pressure of the conduit.

4. The method of claim 2 , further comprising monitoring temperature along the pipe and comparing the pressure to the temperature to determine if a pressure change is from a temperature change.

5. The method of claim 1 , wherein a gas composition within the conduit is continuously monitored.

6. The method of claim 5 , wherein the gas composition is continuously monitored by continuously flowing a gas through the conduit and testing the gas after the gas exits at least one venting port formed in the housing.

7. The method of claim 5 , wherein the gas composition is continuously monitored by extracting a gas from at least one venting port formed in the housing at an interval and testing the gas composition of the gas after extraction.

8. The method of claim 1 , wherein the length of pipe further comprises a plurality of pipe segments and at least one pipe joint connecting adjacent pipe segments together in an end-to-end configuration, wherein the space conduit continuously extends through the pipe segments and the at least one pipe joint.

9. The method of claim 4 , wherein the temperature is monitored using a plurality of temperature sensors.
