It would be able to move between different subsea garages, which would also house various tooling skids, as in 2020-23, ready to pilot a UID that can swim autonomously between stations and perform survey and IMR tasks. well as recharging facilities, and would be open to third party

In fact, Norwegian company Stinger is developing a UID component integration, Giovanni Massari, a Saipem project docking station able to support any resident vehicle.
