The IMMS monitors, logs and displays data in real-time to provide operational support functionality and archives data for assessing the facility's integrity over time.

The Stones IMMS is comprised of a set of subsystems including environmental and facility monitoring, mooring line monitoring and subsea acoustic monitoring of the disconnectable turret buoy.

The IMMS interfaces with other platform control systems and uses BMT proprietary data acquisition system along with custom human-machine interface user display screens.

BMT provided a similar system to the Cascade Chinook field development, the first deepwater FPSO in the GoM.
