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 operational 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.
Refurbishment of operational systems is possible in many cases and it can be done with the help of our experienced climbing crews that will remove instruments, undertake the refurbishment and recalibration and then return them to service.
To help wind farm owners and asset managers understand the data accuracy of met-masts during the development phase and (ultimately protect their margins), Dulas also offers a ground based verification service using our LiDAR units. These are able to identify inaccuracies in the met-mast measurements which may have crept in over time during their deployment in the field. The advantage of this approach is that the accuracy and functionality of meteorological masts can be assessed in the field without having to disassemble and lower the structure and take it out of service. In addition, LiDAR measurements are able to capture data above the height of the met-mast, up to around 200m or more, that helps the developer to understand to wind shear models that are used to predict the wind speed up to the tip height of the turbine.
For expediency the LiDAR can be deployed in less than 4 weeks and are able to measure wind speeds and characteristics from 10 metres to 200 metres or more – ensuring correlations may be performed across a range of suitable heights.
