Pipeline Mapping: Using INS/GPS Data as the Fundamental Tool for Integrating Historical and Current Pipeline Data

摘要

Pipeline operators are today faced with an increasing number of challenges. In addition to implementing more rigorous pipeline integrity programs, integration of pipeline data has now become a major concern. Through the use of a highly accurate inertial navigation system (INS) on board an In Line Inspection (ILI) smart pig, longitude, latitude and elevation coordinates can now be provided along the pipeline every tenth of an inch. This information provides the most accurate reference for integrating and relating pipeline data in a comprehensive manner. One of the most significant benefits to the operator is an absolute reference for integration of legacy and current pipeline data. This paper describes the processes involved in providing a data integration service to a major pipeline operator in the continental United States. Additionally, this paper shall focus on the benefits of combining pipeline-mapping services with an ILI smart pig survey.
