Hydrocarbon Monitoring

Chelsea Technologies Group has a proven range of in situ sensors optimised for monitoring crude and refined oil. Applications include: reporting of hydrocarbon monitoring in ports & coastal areas, within natural water systems, pollution survillance, point source pollution tracking. Systems are also available for detection of leaks in pipelines & subsea installations and for subsea control line leak detection.

Systems to choose from include:

UV Aquatracka for hydrocarbon monitoring in process control or natural water waysUV AquaTracka Fluorometer: Extremely sensitive UV fluorometers for the measurement in real-time of refined hydrocarbons or crude hydrocarbons in a wide range of applications. Suitable for deployment from gliders, undulating vehicles, moored or profiling systems.

OIL-Wader Hydrocarbon Monitoring OIL-Wader & OIL Wader Pro Provides surveyors and regulators with real-time in situ measurement of dissolved Polycyclic Aromatic Hydrocarbon (PAH). The sensors detect UV fluorescence with industry-leading sensitivity and selectivity and has been optimised for minimal interference from water turbidity.

subsea leak detection Subsea Pipeline Leak Detection: This is the industry preferred tool for subsea pipeline leak detection. The system finds leaks by sensing the fluorescence of leaking hydrocarbons or, for pipeline commissioning, by introducing fluorescent dyes (such as Rhodamine, Fluorescein or Agma).

Case Study: CTG UV AquaTracka fluorometers used extensively to monitor the extent & dispersion of oil spill in the Gulf of Mexico.

Originally designed for military use the highly sensitive UV AquaTracka fluorometers monitored the extent of the oil from surface waters to full ocean depth. The fluorometers were used in combination with the FastOcean Fast Repetition Rate (FRR) to monitor the effects of the oil on the primary productivity of the Gulf.

The FastOcean underwent extensive challenge testing to characterise its response to contamination events in the aquatic environment and provided unique real time data on the response of the marine ecosystem to the elevated hydrocarbon levels in Gulf of Mexico.

Long term monitoring of the offshore and coastal waters of the Gulf is fundamental to understand the rate of recovery of the ecosystem from both the oil spill and the chemical dispersants used. The detection and monitoring of very low levels of hydrocarbons over long periods of time, and their effects on the ecosystem, is key.

"The FastOcean is fast becoming the instrument of choice for a range of organizations wishing to investigate the physiological responses of a diverse range of phytoplankton within ocean. The ability to combine this with the high precision UV AquaTracka provided investigators in the Gulf with a powerful tool," reports Loren Hiller, CTG's Sales Manager. Since the introduction of the FastOcean there has been a significant increase in the range of applications from coastal and ocean algal studies to the protection of reservoirs and potable water supplies.
