Statoil operates and provides the technical assistant for the operation and the overall integrity for most of the rich gas pipelines on the Norwegian Continental Shelf (NCF) with the approximate total length of 1700 km. It is very important to operate and maintain the pipeline in the most effective and safest way. Rich gas pipelines provide the gas delivery to processing plants before the gas is exported to the various customers. The gas is pre-processed and dehydrated on the platform before the product quality is measured and the gas is routed into a transmission pipeline. Product monitoring is an essential part within the corrosion management of the pipeline. Corrosion would not occur if no free water was available on the material surface. Hence monitoring the WDP or water content has a high priority in the operation of a rich gas pipeline. In addition to that understanding the water precipitation process in the pipeline together with CO2 and H2S corrosion mechanisms is important for complete corrosion control. This paper will focus on product monitoring and a comprehensive internal evaluation including TEG-water behaviour in a rich gas pipeline as practised within Statoil Pipeline operation.
