ID-227WL Wireless Oil Sheen Monitoring System for Marine Applications

The new Leakwise WL, Wireless oil-sheen detectors, and oil build-up monitors use Orbcomm satellite communication and cellular networks to alert operators of oil leaks/spills. These floating sensors, which use the latest technology of high frequency electromagnetic energy absorption, are unaffected by dirt or oil coating or by changes in water level, salinity, and temperature. This technology enables reliable operation with no false alarm and very low maintenance costs.

The Leakwise IS-227WL system consists of a Wave Rider Buoy incorporating:

  • An oil detection sensor
  • Awireless digital signal processor
  • Wireless communication antennas
  • A solar panel with battery

The wave rider buoy is designed to maintain the position of the sensor's detecting antenna at the liquid-air interface, despite fluctuations in the liquid level due to waves and tide. The ID-227WL sensor can detect as little as 0.3 mm layer of oil on water reliably, repeatedly and without false alarms. It has five levels of adjustable oil alarm set points for monitoring on-line changes in oil layer thickness up to 20 mm.

The wireless digital signal processor (WSP-220) transmits alarm and status messages via satellite and/or cellular and/or other wireless methods in the form of e-mail, SMS message, or other message media. An alarm message will be transmitted when an oil alarm set point is violated. A status message is transmitted every programmable time interval, thus enabling monitoring the oil layer thickness trend. A built-in test feature is continuously monitoring failure free system operation.

Applications
The ID-227WL is designed to be installed off-shore near oil tanker buoy terminals, jetties, and piers in order to detect floating oil sheens resulting from spills or leaks which may occur during the loading/discharge process. Additional applications are available in detecting and monitoring floating hydrocarbons near off-shore oil rigs and in lagoons, lakes, rivers, open channels, and large retention ponds.
