OVERCOMING DATA GAPS ON OLDER PIPELINES: HOW MAGNOLIA RIVER HELPED A MAJOR UTILITY ESTABLISH GIS





The client now has the benefit of an updated GIS map along with the information needed to move forward with pipeline main preplacement. As a result of this success, the same utility enlisted Magnolia River to conduct this service on seven additional projects totaling another 39 miles for other gas system acquisitions.

CHALLENGE:

When a large division of a major utility acquired a new gas system, they planned to replace some of the pipeline based on information from a leak survey to ensure system integrity. While preparing for the replacement work, they quickly recognized they were unable to determine the location or the type of pipeline that was in the ground, which was a significant safety concern. To remedy the situation, they enlisted Magnolia River (MR) to help establish a pipeline main verification and mapping project.

ACTIONS TAKEN:

The priorities were to locate and expose the pipeline mains through soft dig excavation and identify the material and size of the exposed pipeline, a process commonly referred to as “potholing”. Magnolia River would then GPS the existing pipeline and import the mapped areas into the utility’s GIS system.

Magnolia River teamed with a trusted business partner to expose every 100 feet of 31,000 foot pipeline main to identify the diameter and material. MR inspectors provided field services project management and gathered GPS data, which was sent to the MR GIS group for mapping. Once the mapping was complete, it was imported into the utility’s GIS system.

RESULTS

The client now has the benefit of an updated GIS map along with the information needed to move forward with pipeline main preplacement. As a result of this success, the same utility enlisted Magnolia River to conduct this service on seven additional projects totaling another 39 miles for other gas system acquisitions.
