Millions of dollars are spent annually to maintain hydrocarbon pipelines free from any operational breakdowns. In most cases of such breakdowns, the cause is internal corrosion (Figure 1).
Corrosion of offshore oil and gas pipelines is a critical problem that can lead to catastrophic failure if not properly managed—from the design stage of the pipeline system through ongoing monitoring and maintenance.
Far too often these days we’re hearing about oil and gas pipelines giving way to the forces of corrosion. This is an issue that is drawing even more attention because of the combination of an aging infrastructure network, encroachment into urbanized areas and inadequate protection of some sort – be it coatings, cathodic protection, faulty welding, etc. that leads in faulty maintenance.
One of the key factors in meeting the design life requirement of an oil and gas flow or export line depends on the accuracy of corrosion prediction and its management. Therefore, the assessment of internal corrosion of a pipeline system must also include examining the mechanism by which corrosion is expected and understanding how it is most likely to occur.
The Southern Gas Association (SGA) holds an annual conference at which many subjects are discussed involving gas transmission and distribution operations.
The external corrosion protective coating of critical buried flowlines experienced premature coating failure in specific applications at Uthmaniyah Gas Plant in Saudi Arabia.
Tony Keane, executive director of NACE International, recently assembled a panel of NACE member pipeline corrosion control experts to answer a series of questions on the challenges involved with assessing and protecting pipelines at cased road and railway crossings.
Aging infrastructure, new state and federal regulations, unfriendly neighbors, an aging workforce and heightened security restricting site access are burdening company operations with increasing costs and deteriorating operational excellence.
This article shares experiences we have gained working with several customers to geo-code leak and pipe inspection reports and associate them with the pipe segment in the GIS that best matches the address location and other attributes of the report.
How best will the growing volumes of ethanol being produced to comply with federal laws be safely transported from producing plants in regions where there are few fuel transportation assets to consumers?
