The Pipeline and Hazardous Materials Safety Administration (PHMSA) is about to embark on two studies which will be used by Congress to tee up (or not) new safety requirements related to leak detection and automatic and remote controlled shut-off valves (ASV/RCV). But gas transmission, distribution and hazardous liquid pipeline companies and their trade associations are uncomfortable with some of the parameters the PHMSA wants to set. For example, Jeffrey L. Maples, Director, Gas Operations, Paiute Pipeline Company, argues that PHMSA has broadened the two studies to include gas distribution pipelines.

The cone meter is a simple and robust generic differential pressure (DP) meter. It has been shown to be remarkably resistant to the effects of both asymmetric and swirling flow. The cone meter is often the meter of choice when there is limited straight pipe length available for a flow meter. Therefore, cone DP meters are becoming increasingly popular gas flow meters.

The U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) proposed on July 2 a record $3.7 million civil penalty and 24 enforcement actions against Enbridge Energy for the July 25, 2010, crude oil spill near Marshall, MI.

Enterprise Products paid a fine of more than $1 million concerning three spills in Iowa, Kansas and Nebraska. Enterprise Products spokesman Rick Rainey said all three incidents covered by the settlement announced May 29 were caused by factors outside the company’s control.

The Export-Import Bank of the United States authorized a $2.95 billion direct loan to support U.S. exports to the Australia Pacific LNG project.

This article considers the bypass method for capacity control in reciprocating compressors. The method is the oldest in controlling outlet capacity, which is used in all types of compressors for turndown capacity between 100% and zero.

The National Association of Pipe Coating Applicators (NAPCA) heard good news about the volume of 2012 pipeline work expected in North America and elsewhere during the association’s 48th annual meeting in April in Tucson, AZ.

There are over 2 million km of oil and gas production pipelines worldwide and ensuring the effective and efficient flow of products through these pipelines makes a huge difference in revenues generated.

For pipeline owners and operators, efforts to mitigate or control internal corrosion generally fall into one or more of a handful of strategies. Moisture content control seeks to limit the amount of moisture (as measured in grains of water per million cubic feet of product, or by dew point) to eliminate the electrolyte for corrosion cells to develop.

The native-owned corporation that would control a third of the long-delayed Mackenzie Valley natural gas pipeline is open to discussing the idea of a liquefied natural gas project that would allow the resource to be shipped to Asia to kickstart development.
