The World Oil & Gas Pipeline Integrity Management and Technology Latest Development and Chinese Pipeline Countermeasure

The safety of oil and gas pipeline is very important for Quality, Healthy, Safety and Environment (QHSE) policy of PetroChina. How to ensure the safety of pipeline,how to prevent new pipeline from incident and how to make the old pipeline be continually safety operation is a big problem for the pipeline company. This paper discusses the worldwide (Europe, North American, Southeast Asia and Australia) pipeline integrity management and pipeline integrity technology development, mainly introduces the pipeline integrity technology development,including the inspection technology,evaluation technology,risk management technology, maintenance technology, geography information system (GIS) technology and pipeline integrity standard system. The authors consider that the pipeline integrity management theory and technology from overseas should be integrated with China pipelines' status quo. The recommendation countermeasure is to divide the pipeline integrity management application to four divisions; (1) the main pipeline with defects: (2) geological disaster and pipelines' environment; (3) pipeline external coating and its validity; (4) stations and its facilities. And next step is to set up and improve the pipeline integrity management system and pipeline integrity technology, and establish the pipeline data management platform. This will be the effective model for Chinese pipeline integrity management.
