... control systems. The proposal for the project is to have a subsea electrohydraulic module providing all monitoring and control functions for the intelligent well. The proposed system is based on the hydraulic configuration 2 (IWIS option 3), as detailed in the IWIS Recommended Practice A1 to the ISO 13628...
