Cost-effective, accurate, offshore wind resource assessments

The FLiDAR measurement buoy represents a major break-through for the offshore wind industry enabling dramatic cost reductions for offshore wind resource assessments.

It can be deployed in one day and delivers highly accurate wind data throughout the project development. The business concept of FLiDAR is based on a renting model with data service agreement, minimizing financial risk and maximising flexibility for the customer.

The offshore meteorological station is designed for marine renewable energy technologies such as offshore wind, wave, tidal etc. provides real time data access.

FLiDAR is made up of an offshore-ready WINDCUBE®v2 LIDAR, secured on top of a mechanical stabilisation unit on an industry standard buoy. The system is highly accurate due to the combination of mechanical stabilization and software based measurement correction. It has been proven several times to measure wind potential with an accuracy equivalent to fixed offshore met masts, regardless of the sea state.

Features

  • Highly accurate measurement data
  • Industry standard robust buoy structure
  • Commercially proven product

Benefits

  • Lower CAPEX and OPEX of offshore wind resource assessment
  • Reduces permitting requirements
  • Reduces risk on offshore investments
  • Simplify resource assessments, before, during and after construction

Validations

FLiDAR is designed to operate maintenance free and autonomous for more than six months in demanding offshore environments such as the European North Sea area.

The first version of the FLiDAR floating LiDAR product was successfully tested and validated in 2011 in the North Sea. It has subsequently been tested next to a fixed offshore met mast on the RWE Gwnt Y Mor offshore wind farm in the Irish Sea (UK), from October 2012 to January 2013. The reports of these validations by DTU wind energy and Fraser-Nash consultancy can be found in the downloads section.

FLiDAR has been providing commercial services to large utility clients since June 2013.

DONG Energy installed the first FLiDAR in 2013 on one of its offshore wind farm developments in the Irish Sea. After 5 months of successful operation they ordered a second measurement buoy which was also deployed in the Irish Sea in April 2014.

Mainstream Renewable Power kicked off Phase 2 of their floating LiDAR campaign by deploying a floating LiDAR on its 450MW Neart na Gaoithe offshore wind farm. FLiDAR deployed the device almost 21km off the Fife coast on April 20th. The technology is designed to capture valuable hub height wind resource data in the harshest conditions and will remain on site for 6-12 months in support of the Neart na Gaoithe project development.

Prior to the Neart na Gaoithe deployment, the FLiDAR device completed its 3 month Phase 1 validation at NAREC’s (National Renewable Energy Centre) Offshore Meteorological (met) Mast located off the coast of Blyth, Northumberland. DNV-GL (legacy GL Garrad Hassan) were appointed to provide independent oversight of the validation and are now producing an independent report on the accuracy and reliability of the device during the Phase 1 met mast comparison.

Successful validation of FLiDAR technology signals a significant shift from the reliance on fixed offshore met masts in assessing the potential wind resource for offshore wind farms.
