DNV offers geospatial tech support to wind power

Oslo, Norway: Det Norske Veritas (DNV), an independent foundation with the purpose of safeguarding life, property, and the environment, published a new recommended practice document, DNV-RP-J101 Use of Remote Sensing for Wind Energy Assessments. The document provides wind power industry with in-depth knowledge about the use of remote sensing technology for characterising wind resources. It addresses the use of Sonic Detection and Ranging (SODAR), and Light Detection and Ranging (LiDAR) equipment.

“As the size of wind turbines continues to increase, both in terms of blade diameter and hub height above ground, remote sensing is being increasingly relied on to gain vital insight into resource conditions at operating heights well above traditional meteorological towers. As long as this sensing technology is used correctly, it can provide a cost-effective technique to obtain the required data,” said Dr. Tony Rogers, Principal Specialist and a remote sensing expert at DNV.

“DNV’s independent role in developing technology standards together with the key players and authorities is especially valued by the wind industry. This supports the rapid development of the industry, ensuring the highest levels of safety and added business value,” said Robert Poore, Vice President of Business and Service Development at DNV’s Cleaner Energy operations in the U.S.

Poore explained, “A better understanding of the conditions above typical measurement heights is a key part of reducing the uncertainty in energy assessments. The RP, therefore, addresses the planning and implementation of remote sensing measurement campaigns, as well as using the data obtained by remote sensing in energy assessments. Key topics include sitting of sensors to avoid noise and echoes; complex flow effects, correlation with other measurement sources, to name a few.”
