European Defense Review provides a first look at an EU funded Maritime Domain Awareness effort using “Unmaned Semifixed Sea Platforms,” 

“USSPs will develop a highly autonomous, energy efficient unmanned platform prototype, based on miniaturized oil platform technologies and with a wide range of aerial, surface and submarine sensors. It can be deployed in any geographical area, including deep water, and in adverse environmental conditions, so it will be very versatile in operation.”

Naval News reports that Naval Group has been selected as technical coordinator.
