Profile: Neptune Oceanographics Ltd. specializes in sub-sea pipeline leak detection. Our sub-sea leak detection services are able to prevent serious environmental damage by detecting the leakage of hydrocarbons whether gas or oil from risers, sub-sea control systems, water injection systems, manifolds, and other sub-sea facilities. We develop several systems that enable efficient pipeline leak detection. These include long range fluorescent dye detection for tracer dyes & liquid hydrocarbons, acoustic leak detection, hydrocarbon leak detection, differential sub-sea temperature measurement, mono ethylene glycol detection, and hydrocarbon leak detection system. Our hydrocarbon detector can detect oil & gas in water, and can display data in real time. It is primarily a methane detector, and also detects all gaseous hydrocarbons. Our SNIFFIT hydrocarbon detector system uses two types of sensor depending on requirement: a sensor for methane, and a similar underwater gas sensor. A prime application for the technology is detecting leaks from sub-sea gas pipelines and installations. This system covers applications like offshore pipeline & sub-sea installation monitoring, environmental monitoring of outfalls & waste, seabed dredging safety monitoring, methane hydrate exploration, additional data for route surveys gas vents, and marine accident searches & forensics.
