Abstract
The monitoring of oil pipeline is an important task for economical and safe operation, loss prevention and environmental protection from crude oil emission. A leak detection of oil pipeline, therefore, plays a key role in the overall integrity monitoring for a pipeline system. Especially for a long pipeline operated alongside of dense cropland, a leak detection system is an indispensable condition to allow its construction. In this paper, a leak detection and location approach based on double sensors pressure gradient method is proposed. An industrial application to a long oil pipeline is also illustrated. The result of application supports the effectiveness of the proposed method.
