Pipeline companies install oil collection containments in sensitive locations along the pipeline (e.g. near rivers and or groundwater drinking wells) for oil leakage monitoring. When an ID-223 Oil Sheen Detector installed in such a containment detects oil or oil on water, it sets off an alarm in a remote location. The ID-223 Detector may be installed in unmanned remote locations where power and communication lines are seldom available. In such cases, the system can be powered by solar panels, and communication can be done wirelessly.
Most pipeline pumping stations have either oil-water separators or retention tanks for collecting oil spills and stormwater run-offs that may carry oil. Water is continuously discharged from the separator or retention tank directly into the local public drainage system. An ID-223 Oil Sheen Detector is installed near the separator outlet or in the sump to monitor the water discharge continuously. If an oil sheen is detected, an alarm is triggered, the water outlet valve is automatically closed, or the Leakwise system can turn the water pump off. An ID-225 Oil Layer Thickness Monitor can be installed in the separator to monitor the thickness of the accumulated oil layer.
This is especially important in unmanned locations since it will trigger an alarm in the pipeline control centre in case of large spills or leaks. It can prevent the costly removal of oily water before enough oil has accumulated in the separator.
Many shut-off valves are built along the pipeline for emergency and maintenance purposes. In some areas, due to specific environmental regulations, new shut-off valves must be installed in concrete containment where leaks accumulate and can be detected. ID-223 Oil Sheen Detectors installed in these containments continuously monitor these unmanned shut-off stations and, in case of oil detection, send an alarm to a remote location.
