PROCESS CONTROL OF A SUBSEA PROCESSING PLANT

The Tordis subsea separator station is the first commercial processing plant in the world that is located subsea. The station will be installed 200 m below sea level, and will be remotely operated from the Statoil operated Gullfaks C platform, which is located in a distance of 12 km from the Tordis oil field. Operation of the subsea separator station with pumps is a challenge for the design of the control system. By use of dynamic simulation different control strategies have been investigated, and the control system is also tested with the real pumps and instruments connected to the dynamic simulator.
