المستخلص: Pipelines are considered one of the most important sectors of the petroleum industry, as they are one of the most important ways to transport gas and oil from production to refining stations and also to treatment plants for several reasons, on top of which they are considered the safest and least costly, and they are difficult to steal. These pipeline networks are equipped with valves, pumps and controllers. There are several types of pipelines, some of which are intended for the transportation of crude oil, some of which are intended for the transportation of petroleum products, and marine pipelines to transport gas and petroleum, whether for export or for transportation from marine fields to onshore processing plants. In order for the pipeline to fulfill its purpose with minimum losses, there are pre-measures to be taken to guarantee flow assurance throughout the flow line. The purpose of this paper is to perform a study and simulation using OLGA of the gas transport lines at Sabratha offshore platform in Libya. Specifically, Bahr Essalam 36’’ Gas Export Trunk-line to test its ability to withstand new flow rates. focusing on two major challenges which are hydrate formation prevention and slug tracking, so to ensure smooth flows without any interruptions which may cause enormous economic losses, not to mention mechanical plugging or technical issues that may consume a large amount of time to repair. This is done through several possible scenarios that occur during operation, including the emergency shutdown and blow down, as well as the breakdown of one of the gas processing units in the platform. The results obtained from this study showed that the maximum flow rate which can be delivered by the 36’’ export line is 1300MMSCFD and injection of hydrate inhibitors is needed in cases of shutdown. Results also show that the existing slug catcher size is small for the expected liquid in case of raw gas delivery (maintenance on platform).
