Italian transmission system operator Terna has launched the Gavia autonomous underwater vehicle (AUV) as part of a partnership with US startup Terradepth. The program aims to advance marine geophysical surveys to facilitate the development and safety of seabed infrastructure. Terna technicians tested the performance of the Gavia drone while conducting geophysical surveys near Casamicciola Terme. The partnership can test innovative technologies, such as subsea drones, which can complement traditional subsea inspection tools. Italy's National Grid development plan includes large-scale submarine infrastructure projects.
