Met mast verification

Ensure your data accuracy over time

Despite the importance of meteorological masts during wind prospecting, once the wind farm is fully operational, meteorological masts can become a neglected asset, as production priorities and operations and maintenance activity on turbines take precedence.

Over time, neglected masts can have the potential to lose data accuracy, thereby providing owners and secondary investors with incorrect data, which ultimately affects project returns, the investment grade of the development, and client reporting.

To help wind farm owners and asset managers maintain the data accuracy of their masts, and ultimately protect their margins, Dulas has launched a new service with ZephIR Lidar.  Using the ZephIR 300, a finance-grade lidar system that is able to detect many of the causes of inaccuracy in the met mast and validate wind shear models used above mast height, Dulas is able to assess the accuracy and functionality of meteorological masts without having to disassemble and lower the structure.

For expediency the ZephIR 300 can be deployed for less than 4 weeks and is able to measure wind speeds and characteristics from as low as 10 metres to as high as 200 metres – ensuring correlations may be performed on even the shortest masts.

The ZephIR 300

The ZephIR 300 is able to:

  • Identify flow distortion at the anemometer, caused by the mast itself
  • Confirm any deterioration in anemometry calibration over time
  • Discover misalignment of anemometry with respect to the mast
  • Detect anemometry failings during freezing temperatures
