Correct Pigs, Procedures for Hydrostatic Testing of New Pipelines

Laying a cross-country pipeline is expensive. Many hours of engineering and planning must meet certain standards and regulations and receive federal government approval before starting construction. It costs approximately $100,000 per diameter-inch-mile to build a pipeline in a reasonable lay area. This number can easily triple in marsh lands, hills, mountains and rocky terrain. In those areas it could cost about $20 million to lay 100 miles (161 km) of 20-inch pipe.

Doosan, Skyfire Consulting Partner for Long-Range Pipeline-Inspection Project

Skyfire Consulting, a public safety drone consultancy, has announced a partnership with Doosan Mobility Innovations to launch a long-range pipeline-inspection project with a major U.S. pipeline operator.

Drones on Deck to Make Pipeline Inspections Safer, More Efficient

Using unmanned aerial vehicles (UAV) to inspect pipelines is one of the most promising uses of new technologies that our industry has ever seen. Unmanned aerial vehicles, often called drones, can be launched from nearly any location, controlled remotely and programmed to operate autonomously.

Beyond-Visual-Line-of-Sight Drone Inspects Trans-Alaska Pipeline

Researchers at the University of Alaska Fairbanks recently made history by completing the first true beyond-visual-line-of-sight (BVLOS) flight under the small unmanned aircraft systems (UAS) rule.

Robotics Applications Making Advances in Norway

In the oil and gas industry, the use of robots, whether fixed or mobile, is not new, as such devices were introduced to a lesser extent in the 1970s. Today, however, we are beginning to see highly advanced applications of such robotics being used.

Improving Data Loss During In-Line Inspections

Although there are other inspection methods, such as direct assessment or hydrostatic testing, ILIs are the most popular worldwide due to number of factors, including practicality, cost-effectiveness and accuracy.

PHMSA Publishes "Mega" Rule After Nearly A Decade of Work

U.S. transportation officials on Tuesday adopted long-delayed measures that are meant to prevent pipeline spills and deadly gas explosions but don't address recommended steps to lessen accidents once they occur.

Iran Checks Cyber Security at Key Energy Sites

Iran has launched an inspection of security at its key Gulf oil and gas facilities, including preparedness for cyber attacks, the Oil Ministry news agency SHANA said, following media reports of Washington weighing possible cyber attacks on Tehran.

Feds Recommend New Requirements After Natural Gas Disaster

Federal officials are recommending stronger nationwide requirements for natural gas systems following last September's natural gas explosions and fires in Massachusetts.

Digital Alternative to In-Line Inspection

There are two traditional schools of thought for monitoring internal corrosion in pipelines. One advocates the use of theoretical modeling techniques to predict the location, severity and behavior of corrosion; the other favors inline inspection (ILI) as a means to measure corrosion directly.

East Africa’s Leakage Incidents Points to Detection Needs

Barely one year after the commissioning of East and Central Africa’s only refined oil transportation pipeline in Kenya, leakages have been reported, raising concerns about the ability of existing government agencies to monitor the safety of oil infrastructure at a time when similar projects have been unveiled across the region.

Looking to Lessen Fluctuating Flow Problems in Measurement

Good measurement practices suggest flow measurements should occur without instabilities or pulsations in the flow. Even minor inaccuracies in the measurement of high value products can lead to significant financial exposure over extended periods of time.

Using Computational Fluid Dynamics When Equipment Fails

The importance of accurate measurement cannot be under-estimated. In 2012, the oil price was above $100 per barrel, but only a year later, as oil prices began to decline, the average price of a barrel of crude oil was $91, dropping to $42 by 2015.
