The project aims at validating the high-level RoboVaaS vision via a selection of identified services by addressing near-shore maritime operations that have a strong benefit on automation and digitisation: The anti-grounding service allows a ship to book an USV that travels ahead for safe guidance through shallow water. The inspection service can be ordered by ships to get a robotic hull and propeller inspection via USV and ROVs while e.g. loading or bulking in port. The data collection service has a wide range of application such as measuring ship emissions or cost-efficient autonomous bathymetry survey of waterways with an USV. RoboVaaS will perform necessary scientific and technological developments to validate these services on three levels in real (small- and large-scale) and virtual (full-scale) demonstrations.
