MindChip is developing an autonomous surface vessel for harbour monitoring and cleaning application. We have developed a robotic vessel for autonomous data collection and seabed/underwater infrastructure monitoring for harbour basins, quays and fairways. Our focus is on the detection of siltation, oil spills, floating obstacles and in the condition monitoring of the underwater infrastructure. We aim to provide a technical solution for fully autonomous regular service, meaning that repeated monitoring cycles in harbour basin and the recharging of the vessel are done without any need for human interaction. Gathered data can be used to develop an almost live digital twin of the harbour is provided for the user. As a side benefit, the floating waste can be collected from water surface during the monitoring runs. In addition, our situational awareness and navigation solution, trained in demanding harbour environment, has a potential to be developed into a separate product for manned vessels improving their autonomous capabilities and manoeuvering safety.
