Wind Measurement
In wind farm business, wind observation using various instruments such as met-mast or Doppler LIDAR is imperative.
We provide high-quality and high-stable wind observation complying with domestic/global standards (eg. IEC, JIS) and guidelines (eg. MEASNET - Evaluation of Site Specific Wind Conditions; Certification for Onshore Wind Farms) in cooperation with our technical partners CLIMA-TEQ and SEIDENSHA.
1. Observation planning
<Outline>
We draw up plans of wind observation using met-mast and/or Doppler LIDAR based on desk research and on-site survey.
<Our sales points>
- Conduct desk research to line up candidate observation points based on GIS data and satellite images by considering buildings, trees and terrain structures around the target areas.
- Conduct on-site survey to identify the location data, peripheral status, power supply availability, etc. required to draw up a final observation plan.
- Base on NEDO's "Wind Farm Development Support Project (Establishment of Wind Survey Method)" and the latest knowledge in global/domestic to meet wind farm certification requirements.

2. Met-masts (observation towers)
<Outline>
We provide a seamles service from mast equipment procurement, installation, observation, maintenance, removal, and observation data organization.
<Our sales points>
- Provide a mast installation report, and monthly/annual wind observation reports.
- Examine whether the mast structure and equipment design (installation boom, etc.) meet global/domestic standards.
- Examine whether the sensor models are appropriate for the sites (eg. a three-cup wind speed meter, and arrow-type wind speed meter).

3. Doppler LIDAR
<Outline>
In addition to vertical LIDAR that target only directly above wind, other technologies, especially for offshore observations, have been proactively development such as scanning LIDARs that use spherically irradiated laser beam to observe several-km away and floating LIDARs that are vertical LIDARs mounted on offshore buoys.
We provide a seamless service from mast equipment procurement, installation, observation, maintenance, removal, and observation data organization.
<Our sales points>
- Conduct services even for harsh environments such as heavy snow areas, building rooftops, etc.
- Recommend the best scanning LIDAR model considering with the site conditions.
- Provide a plan of turbulence intensity observation based on the knowledge of NEDO’s "Fixed Offshore Wind Farm Development Support Project (Establishment of Offshore Wind Survey Method)"
- Conduct paperwork required to apply permits/licenses related to floating LIDAR installation.
