A leakage mitigation system includes a leakage detection device having a canister configured to: (i) contain a first reactant and a second reactant and, (ii) based on a volume of liquid leaked from a tank, allow the first reactant and the second reactant to react with each other to produce a gas. A shut-off valve coupled to an inlet pipe of the tank is configured to actuate between an open condition and a closed condition. Further, a conduit extending between the leakage detection device and the shut-off valve allows flow of the gas from the leak detection device to the shut off valve. In order to mitigate the leakage of water, the shut-off valve is actuated between the open condition and the closed condition based on the pressure exerted thereon by the flow of the gas.

Systems and methods for efficiently identifying gas leak locations may include traversing, by an investigator and within a search area in which a gas leak has been indicated, a route defined according to at least one of a surge-cast algorithm or a surge-spiral algorithm. The systems and methods may also include sampling, with a gas detection device carried by the investigator, an environment along the route to identify a location of the gas leak.

Technologies for producing efficient investigation routes for identifying gas leak locations include a mobile compute device. The mobile compute device includes circuitry configured to obtain route data indicative of a route to be traveled along to identify a location of a gas leak. The circuitry is also configured to present the route data to a user to guide the user along the route.

A petroleum pipeline safety system for preventing contamination of an environmentally sensitive area close to a pipeline is provided. The system includes a first portion of the pipeline including an upstream portion of the pipeline supplying a flow of fluid material and a flow restriction downstream of the first portion of the pipeline. The system further includes a second portion of the pipeline downstream of the flow restriction, receiving the flow of fluid material from the first portion and conveying the flow of fluid material through the environmentally sensitive area to a downstream portion of the pipeline. The flow restriction is configured to create a lower pipeline internal pressure within the second portion as compared to a pipeline internal pressure within the first portion. The system further includes a third portion of the pipeline downstream of the environmentally sensitive area and including the downstream portion of the pipeline.
