Based on long-range fluorometer technology, Neptune’s fluorescent leak detection system responds to a wide variety of fluorescent dyes and liquid hydrocarbons at low concentrations.
Neptune’s sensors can maintain this level of functionality in turbid conditions, and with high spatial coverage.
The long-range remote sensing fluorometers have a proven track record of success, detecting crude and lubricating oil, along with hydrocarbon-based control fluids.
They feature a forward facing ‘tuned’ light source (like a torch) that produces a beam of excitation light which spreads to about 40cm diameter at 3m. Fluoresced light signals generated in the leaked fluid are detected by the sensor and converted for transmission to the surface via the ROV umbilical for display and recording.
By mounting the fluorescence detector on the ROV manip, quick and easy scanning for leaks is achieved without needing to consider tidal flow direction to ‘capture’ dye, as is necessary with most fluorometers.
