Bore and annulus monitoring pipe breach detection systems and methods

A method of operating a monitoring apparatus deployed in a pipeline system, comprising:

• determining, using a control sub-system in the monitoring apparatus, a bore monitoring integrity state that indicates whether a breach is potentially present in a pipe segment deployed in the pipeline system based at least in part on first sensor data determined by a plurality of bore sensors in the monitoring apparatus to be indicative of one or more bore fluid parameters present within a pipe bore of the pipe segment;
• determining, using the control sub-system, an annulus monitoring integrity state that indicates whether a breach is potentially present in the pipe segment based at least in part on second sensor data determined by one or more annulus sensors in the monitoring apparatus to be indicative of one or more annulus fluid parameters present within free space defined in a tubing annulus of the pipe segment;
• and
• determining, using the control sub-system, a cross-checked integrity state that indicates whether a breach is actually present in the pipe segment at least in part by cross-checking the bore monitoring integrity state and the annulus monitoring integrity state against one another.

A monitoring apparatus, comprising:

• a plurality of bore sensors, wherein the plurality of bore sensors is configured to be fluidly connected to a pipe bore of a pipe segment to enable the plurality of bore sensors to determine first sensor data indicative of fluid pressure present within the pipe bore of the pipe segment;
• one or more annulus sensors, wherein the one or more annulus sensors are configured to be fluidly connected to free space defined within a tubing annulus of the pipe segment to enable the one or more annulus sensors to determine second sensor data indicative of fluid pressure, fluid temperature, fluid flow rate, fluid composition, or any combination thereof present within the tubing annulus of the pipe segment;
• and
• a control sub-system configured to be communicatively coupled to the plurality of bore sensors and the one or more annulus sensors and to:
• determine a bore monitoring integrity state that indicates whether a breach is potentially present in the pipe segment based on the first sensor data indicative of fluid pressure present within the pipe bore of the pipe segment;
• determine an annulus monitoring integrity state that indicates whether a breach is potentially present in the pipe segment based on the second sensor data indicative of the fluid pressure, the fluid temperature, the fluid flow rate, the fluid composition, or any combination thereof present within the tubing annulus of the pipe segment;
• and
• determine a cross-checked integrity state that indicates whether a breach is actually present in the pipe segment based on the bore monitoring integrity state and the annulus monitoring integrity state.
