Dynamic simulation results of thermal and hydraulic performance of the Gemini deepwater subsea production system of three wells and two pipelines are presented. This paper shows how transient models such as OLGA are used to predict and alleviate the flow assurance problems associated with deepwater production of a gas condensate subsea system. The paper addresses the importance of flow modeling before and during production. The results of this study can be applied to the design of new deepwater production systems in order to maintain flow assurance, and to safely operate a subsea pipeline/riser system. Comparisons of predictions with the measured production data are presented.
