ROV-Mounted Thermal Leak Sensors

ROV-Mounted Thermal Leak Sensors

Under some circumstances such as with water injection flow lines and high pressure control systems, leaks can be identified using temperature detection of the difference between the surrounding seawater and the water leaking from the flowline. The flowline water temperature is normally above ambient seawater temperature due to the high pressure pumping required. Neptune Oceanographics has developed a differential temperature technique that can detect very small temperature changes. The thermal leak detector comprises a fast, high precision thermistor connected through the Neptune Oceanographics leak detection system to the ROV umbilical for onboard display and recording.
