Abstract

Subsea multiphase boosting is a technology that is gaining interest from oil & gas operators and suppliers. In response to the growing interest in multiphase boosting technology, GE is working on the development of a subsea multiphase boosting station. In this work, controller synthesis needs are identified for safe and reliable operation of the boosting station. In order to implement and validate control strategies pertaining to the multiphase pump and subsea boosting station, an integrated co-simulation environment is used. After estimating certain process parameters, various control strategies are developed to meet the control objectives. The strategies are distinguished based on sensor requirements, implementation difficulty, efficiency and expected production. Performance of the controllers are tested in the most severe conditions the boosting station may be subjected to. Finally, sensitivity analysis is done to test the control strategies in the presence of uncertainties.
