The Intelligent Mattress Frame (IMF) has been developed to provide a cost effective solution for mattress installation without the need for ROV or diver intervention. The sophisticated tooling can be used to monitor and deploy concrete mattresses to the seabed, disconnect the deployment rigging and conduct a visual/ sonar confirmation of the mattress location. The IMF is a stand-alone unit, fitted with four vectored Thrusters and a standard fibre optic gyro for movement in the X and Y axis.
