Oceanographic - Oil in Water Monitoring / Hydrocarbon Detection & Monitoring

Chelsea Technologies Group has a proven range of in situ sensors optimised for monitoring crude and refined oil. Applications include  detection of leaks in pipelines & subsea installations and for subsea control line leak detection.  Systems are also available for hydrocarbon monitoring in ports & coastal areas. Systems are also available for monitoring hydrocarbons in process control and water treatment plants. 

Systems include:      


UV AquaTracka Fluorometer

  UV AquaTracka Fluorometer: Extremely sensitive UV  fluorometers for the measurement in real-time of refined hydrocarbons (360nm) or crude hydrocarbons (440nm) in a wide range of oceanographic applications. In support of this, it has been designed to be deployed from gliders, undulating vehicles, moored or profiling systems.  

 Subsea Leak Detection

Subsea Pipeline Leak Detection

  Subsea Pipeline Leak Detection: Finds leaks by sensing the fluorescence of leaking hydrocarbons or, for pipeline commissioning, by introducing fluorescent dyes (such as Rhodamine, Fluorescein or Agma). This system provides both offshore pipeline commissioners and project engineers a highly sensitive detection system which allows quick location of leaks within subsea structures.  

Oil Wader


Dr Cathy Rushworth is shown left using the OIL-Wader  to monitor hydrocarbons in Southampton Marina.  It is the tool of choice for real-time hydrocarbon monitoring of ports & coastal area.  


The OIL-Station and OIL-Wader Systems enable in situ, real-time, reporting of Hydrocarbons within Waste Water Treatment Plants, water processing plants and natural water systems. The principle behind the measurement is the excitation of polycyclic aromatic hydrocarbon fluorescence within UV wavelength band, which has been shown to correlate with hydrocarbon contamination with high sensitivity.  These systems can inform on hydrocarbon content at abstraction points and hydrocarbon contamination into processed waters tanks and entering into waste water treatment works.
