Project Purpose

Dominion Energy, on behalf of the Virginia Department of Mines, Minerals, and Energy, has developed the Coastal Virginia Offshore Wind (CVOW) Pilot Project in federal waters 24 nautical miles (43 kilometers) off the coast of Virginia (Figure 1). In 2019, Dominion contracted Normandeau Associates, Inc. to provide postconstruction monitoring for the CVOW Pilot Project. Normandeau's Acoustic and Thermographic Offshore Monitoring (ATOM™) systems are deployed on platforms underneath the two CVOW Pilot Project offshore wind turbines. They collect thermographic and natural light imagery within the rotor swept zone (RSZ) and the vicinity of the wind turbine 24/7 during the monitoring period. Additional ATOM™ sensors include bird and bat acoustics and VHF/MOTUS Nanotag receivers and antennae. Normandeau also conducted six boat-based surveys every other month during the first year of operations using a transect design (Figure 1).

This Dominion CVOW ReMOTe site is Normandeau's data management, analysis, and reporting center for the Dominion CVOW project. It provides access for image analysts to review animals found in thermographic (Figure 2) and visible light (Figure 3) video data, and track acoustic and VHF/MOTUS detections. It also provides results for the following components of the Dominion postconstruction monitoring:

• Results of boat-based visual bird surveys
• Results from the VHF/MOTUS receivers
• Results from the bird and bat acoustic sensors
• Results from the thermographic and visible light cameras, including
• Identification
• Number of individuals
• Flight height
• Flight speed
