Caused by improper crimping of the steel sheet in the production process, roof topping is a geometric anomaly that occurs along the longitudinal seam weld of the pipe. These incorrectly crimped sheets then result in a deviation from the perfectly circular geometry of the pipeline. The implications of roof topping for pipeline integrity are severe. They include risk of failure during hydro-testing or fatigue failure during pipeline operation.

The July 10, 2012 preliminary report from the National Transportation Safety Board (NTSB) on the major oil leak from an Enbridge pipeline in Michigan in July 2010 faults the company's operational and training procedures in numerous instances.

Creating a process for 49 CFR control room regulation compliance requires a great deal of thought, but ensuring that the hard work put into the investigative and implementation phases continue past a few months can require even more thought. To realize these benefits, pipeline operators must rise to meet a number of challenges, not the least of which is managing change.

The world’s energy picture is a complex mixture of factors. For years, oil has been the dominant source of energy in many countries. But in the past ten years, it has become clear that the world’s supply of oil is not unlimited, and that over time alternative sources of energy must be found.

With world population growing at a steady pace (the earth will be home to more than 9 billion people by 2050), global demand for energy is rapidly increasing and the untapped oil reserves lying in Africa are more and more attractive. Africa nowadays supplies around 11% of the world’s oil, but it is expected to pass North America soon to become the third-largest producing area after the Middle East and Central and Eastern Europe.

America is depending on natural gas for its energy future, and pipeline operators are focused on ensuring that their systems provide safe and reliable delivery. Doing so has its challenges, many of which can be managed through the use of technology to solve critical pipeline integrity management issues.

Natural gas production from shale, coal bed methane and tight sands is expected to generate significant job creation, economic growth, and revenue for federal, state and local treasuries throughout the U.S. in gas producing and non-producing states alike, according to a new IHS Global Insight study.

There are striking similarities between the pre-dot com period and today’s growing use of mobile technology. That is not to suggest now is the time to contemplate a new stock market boom. It is just that today’s mobile technology resembles what was then the Internet - much discussed, used en-masse by consumers and watched but yet to be widely adopted by business. In this article we discuss mobile: demystify it and look at current practices in the pipeline sector and how mobile can potential improve process and efficiency.

Optical fiber is increasingly being deployed in many upstream and midstream applications. It is now regularly used to provide high bandwidth telecommunications and infrastructure for SCADA, and is being used more to sense pressure, temperature and strain, along buried onshore pipelines, on subsea pipelines and down hole. In this article results are presented from the latest sensing capability using standard optical fiber to detect acoustic signals along the entire length of a fiber.

Clamp-on ultrasonic meters provide accurate measurement for natural gas reservoir storage wells and in several other applications. Natural gas is stored during the warm months so it is available when demand increases.
