With recent FERC approval for its comprehensive pipeline infrastructure replacement program in hand, NiSource has undertaken the initial five-year investment plan for the Columbia Gas Transmission pipeline and its related facilities.

In less than three years, the San Francisco-based combination utility Pacific Gas and Electric Co. (PG&E) has had to reconstitute its vast natural gas transmission and distribution system on a scale that is unprecedented for the U.S. pipeline sector.

With what could be viewed ominously as the perfect storm bringing a much rougher winter than last year’s to New England, concerns about the need for additional natural gas infrastructure in the region have once again been dramatically underscored.

We live in an era when natural gas and pipelines are part of everyone’s vocabulary. Never have pipeline operators and the companies that service them had to work more closely to ensure that natural gas is delivered reliably and most important safely throughout our vast underground transportation network.

Since it was formed in 1961, the American Public Gas Association (AGPA) has played an instrumental role in the operations of more than 700 member companies in 36 states. The non-profit trade group has a number of vital functions that serve the interests of the industry and ultimately the consumers who are buying that natural gas in increasing amounts and will continue to do so far into the future.

Oil and gas companies need to change their perspective on cybersecurity initiatives from one of incident-based response to a holistic approach more analogous to counterintelligence to prevent espionage, said experts attending IHS CERAWeek 2013, March 4-8. A two-part strategy to decrease exposure and mitigate possible consequences was recommended for a realm where the consensus was that some degree of infiltration is nearly inevitable.

This article describes the two different process applications and quality-control aspects of zinc for corrosion control. A question often faced by engineers and material procurement personnel concerns making a choice between hot-dip galvanized material and zinc-electroplated options. The process, properties and quality-control issues of the two are discussed here in simple terms. This article also references typical applicable ASTM specifications.

Establishing pipeline integrity requires identifying specific threats, understanding their relationship to the condition of the pipeline, and establishing what mitigative measures are appropriate to assure integrity. The pipeline industry has relied on many years of research and experience to develop a set of tools to perform qualitative analyses of pipeline integrity. With the implementation of the Integrity Management Program (IMP) by the Pipeline and Hazardous Material Safety Administration (PHMSA), the analysis methods and results must be defendable and documented.

Custody transfer measurement in the oil and gas business has been described many ways. It has been called, “An accuracy in measurement that both the buyers and sellers can agree upon” and “The best that can be achieved to meet the contract conditions.” But I prefer to call it, “The search for the truth.”

Corrosion is a widespread problem across many industries. Corrosion-related costs to the pipeline industry are estimated anywhere from $5.4 billion to $8.6 billion annually in a report by NACE and CC Technologies. These costs include failures, capital, and operations and maintenance.
