Imaging Analysis System Monitors Mexican Gulf Oil Spill
A single FlowCam oil spill imaging and analysis system from laboratory instrumentation manufacturer Fluid Imaging Technologies (USA), documents the presence of oil spilled in water and also measures its impact on coastal marine microorganisms. Effective in testing samples of sea water, freshwater and/or estuarine water, the FlowCAM particle imaging and analysis system automatically takes hi-resolution, digital images of every individual oil droplet, particle and waterborne microorganism detected, measures each one based on size, shape and dozens of other parameters in real time and saves the images and data for identification and analysis - with a date/time stamp to aid admissibility as legal evidence. Able to
automatically calculate the concentration of oil, grease and other particles in water, the FlowCAM is ideal for locating the boundaries of oil spill plumes at varying depths and verifying the effectiveness of dispersants and other remedial activities. The FlowCam is currently involved in monitoring the BP oil leak in the Gulf of Mexico under the direction of the National Oceanic and Atmospheric Administration (NOAA).
The FlowCam also features a fluorescence mode that reveals the presence of living algal cells, fish larvae, krill and other types of plankton, which form the basis of the aquatic food chain. Acquiring up to 10,000 images per minute, the FlowCam enables plankton ecologists, municipal officials and others concerned about protecting the ocean and shoreline to conduct time series studies that compare and track plankton levels in a region before, during and years after an oil spill. The data provides an indicator of the overall health of the ecosystem for use in assessing the impact of an oil leak or spill.
Reader Reply Card No 145 New Crude Oil Sampler
A new design of electric motor powered crude oil sampler has been delivered to the Middle East for installation on Jetty Sampling systems by Maurer Instruments (UK). The proven three-step action of the sampling head namely the - sample isolation , pump to receiver and retract to start position sequence is characteristic of the original Maurer Samplers developed in conjunction with BP Exploration in 1982 is retained in the new sampler.
The use of a bevel gear box has allowed the motor to be concentrically mounted with the main sampling cell section to yield a compact system and avoid the problems associated with a cantilevered motor configuration. A feature of the Maurer design permits the unit to be split into easily serviced sections that can be removed from the flanged cell without having to break and open the pipe lin. The motor controller has a facility for spot sampling which can be initiated remotely or locally to the sampler in addition to the separately controlled time or flow proportional sampling modes. The complete unit which is powered by 200/240 VAC 50/60 Hz single phase is ATEX approved for use in hazardous areas.
Designed for full ANSI Class 300 operation, the sampling rate is variable to a maximum of 15 grabs /minute. Once again the Maurer Engineering has once again produced a superb instrument that like its predecessors the Pneumatic and Hydraulic Samplers is designed to give decades of proven continuous reliable operation. Maurer Instruments Ltd has also recently obtained PED approval for their range of Constant Pressure Receiers and Piston Internal Mixing Receivers ( PIMR’s). Maurer Instruments philosophy has always been to design and manufacture its products to a high standard than down to a low price. As a consequence Maurer built flowmeters and samplers are still running reliably after more than four decades of continuous operation.

Leakwise Oil-on-Water Monitoring and Detection Systems from GE Analytical Instruments (USA) provide early, reliable, low maintenance warning of hydrocarbon leaks and spills. Leakwise systems provide reliable coverage 24/7 with no false alarms, operate virtually maintenance free for years, detect and measure oil layer thickness (as little as 0.3 mm)and offer an affordable solution for oil leak detection.
Flexible Leakwise systems can comprise a single analog sensor/ controller or multi-unit digital networks, with wired signal, wireless radio, and GSM communications capability.
The unique sensor technology is based on high frequency electromagnetic energy absorption Each sensor is designed to give reliable monitoring of hydrocarbon layers even when it is coated with dirt or oil, or encounters changes in water level or water pH or salinit.
A new application for Leakwise is monitoring oil leaks into clean water ballast tanks. Leakwise has proven to be an effective method for controlling oil crossover into clean water ballast tanks on floating barges – proof that Leakwise strengthens any vulnerable discharge points in SPCC plans.
Other applications include oil leak monitoring at refineries, petrochemical plants, pipelines, tank farms, gas stations, power plants, underground transmission, remote substations, transformer switchyards, marine ports, airports, steel and aluminum manufacturing plants, groundwater and stormwater runoff, wastewater treatment plants and more.
