Disclosed is a fluid leak detection system for monitoring leaks in a pressurized vessel. The system includes a temperature sensor, a pressure sensor, and a processing module. The processing module is configured to any one or combination of: compare a temperature output from the temperature sensor to a reference temperature to produce a temperature differential; or compare a pressure output from the pressure sensor to a reference pressure to produce a pressure differential. The processing module is configured to any one or combination of: monitor the pressure differential to indicate when a leak occurs in a pressurized vessel; or monitor the temperature differential to indicate when a leak occurs in a pressurized vessel. The processing module is configured to generate an alert when a leak is detected.

Sensor for high-pressure line and method for manufacturing thereof. The sensor detects parameters or properties of fluid conducted in a high-pressure line while maintaining the high pressure of the fluid. The sensor includes an inner tube extending concentrically in the outer tube that together form a tube and at least one groove which extends in the inner surface of the outer tube or in the outer surface of the inner tube in a longitudinal direction, at least one signal line arranged in the groove, and at least one pick-up element connected to the signal line and arranged at least in the groove or in at least one recess which is provided at least in the outer surface of the inner tube or in the inner surface of the outer tube in addition to the at least one groove. The outer tube is in frictional connection with the inner tube.

The present disclosure provides a method and a device for detecting a fault of a monitoring device. The method includes: obtaining monitoring data at a preset sampling period, wherein the monitoring data comprises monitoring values respectively corresponding to a plurality of sampling points; calculating a monitoring value change rate between each monitoring value and a following monitoring value based on the preset sampling period; performing normalization processing on each monitoring value to obtain a normalized monitoring value corresponding to each monitoring value; determining a first number of monitoring values each having the monitoring value change rate greater than a preset change rate threshold and the normalized monitoring value greater than a preset monitoring value threshold; judging whether the first number is less than a first preset number threshold; and determining that the monitoring device has a fault if no.

Systems for containing a fluid leaked from a pipeline include a flexible, impermeable liner comprising a coated substrate and disposed to extend along a trench for enveloping the pipeline deployed therein; and separating means disposed between the pipeline and the liner for containing the fluid therein; wherein the liner prevents migration of the fluid into the trench by flowing the fluid laterally within the liner. Methods for deploying the above systems are provided.
