industrialization, to bring flexibility in fabrication and increase the use of a local supply chain in the project fabrication life cycle.OCG-Data is an innovative multi-disciplinary ocean observer for complete offshore site assessment. It has enough footprint to host and power multiple instrumentation packages for resource and environmental characterization. Underwater biodiversity monitoring relies on the combination of restoration technologies and passive acoustic monitoring arrays. The buoy also hosts a bird and bat detection and identification system. OCG-Data provides high-quality data including ecological information for stakeholders' engagement.
