The project is likely to become the new standard in floating lidar devices. It delivers a customised full suite of meteorological and metocean data, in addition to the wind speed & direction data used for resource assessment, to better inform the development of offshore wind farms.
WindSentinel combines the well-proven NOMAD buoy, which is designed to perform in harsh marine weather, and the ZephIR 300 continuous wave (CW) wind lidar with more than 200 individual IEC compliant performance validations. The design philosophy for reducing risk associated with met data acquisition provides dual or even triple redundancy on all major components and the inclusion of two wind lidars allows for staggered servicing of the wind measurement sensors to permit continuous data capture during the campaign.
“Every element of our WindSentinel floating lidar buoy aims to include the best-in-class of each and every sensor, cable and connector” said Terry Tarle, President & CEO at AXYS, speaking at the Ocean Business 2015 technology event at Southampton in the UK. “ZephIR 300 is a proven market leader in the lidar sector and providing clients with an option for dual deployment really does offer an unparalleled level of risk reduction. We are also pleased to now offer ‘Data as a Service’ to the industry with no need to acquire technology, just the high quality data it provides. We can mobilise to any site, anywhere.”
Ian Locker, MD at ZephIR Lidar, added that the company has been working with AXYS since 2007 when ZephIR was installed offshore on a purpose-built meteorological station. AXYS are now delivering fleets of their WindSentinel floating lidar buoys for offshore wind resource assessment at a fraction of the cost, and time, of a traditional fixed met mast.
ZephIR 300 is a continuous wave (CW) wind lidar that provides high resolution measurements at an unmatched data rate of 50Hz. Every second, 50 points are measured in the free space targeted by the sensor, and chosen by the user, anywhere from 10 metres (33 feet) up to 200 metres (656 feet). This type of CW wind lidar gives very accurate measurements of the wind speed, direction and other characteristics including Turbulence Intensity (TI). ZephIR 300 is also the single most validated wind lidar at a consistent IEC compliant met mast site.
