DESIGN AND MODELLING OF BACK PRESSURE REGULATOR AND MEG FILTER FITTED TO SUBSEA SKID EQUIPMENT DEPLOYMENT

Abstract: SSCD is offshore marine structure used for equipment deploying into deep sea. Retrieval of subsea equipment using conventional retrieval tools is difficult due to absence of lifting arrangements and the tools may damage. When Subsea equipment is damaged, it needs to be retrieved and taken to the offshore rig platform for maintenance. This process usually takes 72-96 hours. During the retrieval of Subsea equipment, the process is disrupted, to overcome these difficulties a special SSCD frame (Back pressure regulator and MEG Filter) is designed to avoid damaging of equipment, to reduce operational time. The main aim of this project is to design Back pressure regulator, MEG Filter and analysis of various conditions of SSCD, when the Back pressure regulator and MEG Filter components are to be fitted to SSCD frame. The frame deploys the components in subsea and thus, the frame is called as SSCD. (Subsea skid for component deployment). Back pressure regulator is a control valve which maintains a constant fluid output. MEG Filter is an injection valve acts as a hydrate inhibitor when extracting the gas from undersea.
