Catch-the-Wind Laser Wind Sensor Deployed by AXYS Technologies

Catch the Wind Ltd.'s Vindicator Laser Wind Sensor (LWS) has been deployed by AXYS Technologies as part of validation testing of the WindSentinel, the world's first offshore wind assessment buoy. Commercial launch of the WindSentinel, which combines an AXYS floating platform with a Vindicator LWS, is expected once testing is successfully completed.

AXYS and Catch the Wind had entered into an OEM distribution agreement pursuant to which AXYS was granted a license to combine and integrate the Vindicator LWS with custom AXYS salt/fresh water fixed and floating platforms, and sell the bundled products worldwide.

Validation testing of the WindSentinel buoy is being conducted off of Race Rocks Island, in the coastal waters of British Columbia, Canada. The validation testing is designed to compare wind data collected by the Vindicator LWS on the moving buoy to wind data collected from a second, stationary Vindicator LWS, on Race Rocks Island 0.5 kilometers away.

The test site at Race Rocks Island was specifically chosen to thoroughly test the buoy's capabilities. The waters surrounding Race Rocks see currents of 5 to 6 knots, waves from 2 to 4 meters high and winds up to 50 knots.

The WindSentinel was designed to assist offshore wind farm developers in determining the available wind resource at potential wind farm sites. It is the world's first wind resource assessment buoy capable of accurately measuring wind data at heights of conventional offshore wind turbines. Historically, wind farm developers have had to construct permanent offshore meteorological towers or "met masts" to collect wind speed and direction data. It is estimated that offshore met masts can cost as much as U.S. $10 million to build.
