Precision Auger Boring

Friday, August 21st, 2015

Installing pipelines can be a very daunting task. It requires precision familiarity and calculated decisions since the risks involved are simply too great. Columbia Gas is the largest utility in the state of Ohio with a clientele of about 1.4 million in both residential and commercial users. Last summer, this company had a very challenging project in front of them, and recruited the help of Miller Pipeline Corp. to install a pipeline through an existing line in Columbus across a 280-foot main gas line and had to cross the heavily travelled I-71. The project required precision drilling and the team has decided to do an auger boring method over the horizontal direct drilling. Due to the nature of the area, a trenchless method was necessary. Any wavering in the straight line could be very risky and might cause the operation to stop. Ground conditions were studied and precise auger boring was recommended as the best method to use. Ray Kennedy, the supervisor on the job, knew they only had one chance, and that if they failed the entire project would have to be shut down. They needed a clear view of the bore path so they used an On Target Steering System, a guidance system so they would be able to track what the rig was doing at all times. Read the full article here

Trenchless pipe repair

Friday, August 21st, 2015

Trenchless pipe repair technology is not only an advanced way of repairing and correcting sewer lines but also an economical one. It requires innovation since each repair is different and requires customization to meet client and market needs. Rehabilitating, replacing and installing underground structures can be done faster and cheaper using this procedure. Trenchless pipe repair technology involves several methods such as cured in place pipes (CIPP), pipe bursting thermoformed pipes, slipligning, gunite and more. Trenchless pipe repair has become a leading method in the civil engineering and construction sectors due to its numerous advantages. The development of modern repair equipment made previously complicated sewer repairs possible in a shorter amount of time. There are now sewer cameras that can help you identify cracks faster and easier, allowing teams to easily target damages and focus repairs. With these robotic trolley-cameras, routine checks on homes and industrial pipes can now be done without disrupting the surrounding environment.
Link Pipe is a manufacturing company that provides full range municipal and industrial repair and allied services. They have 35 years of experience in the industry making complicated repairs using all sorts of applications on both industrial and home repairs. Read the full article here

Valves: Block, remote, automatic – which is best?

Wednesday, August 19th, 2015

There are three basic types of valves found in pipelines: manual valves, remotely controlled valves (RCVs), and automatic shutoff valves (ASVs). The manual valves needs direct manpower to shut off valves on location. The remotely controlled valves can be turned off from an offsite control room. Lastly, the automatic shutoff valves are valves that can shutoff automatically without human assistance when the pipe malfunctions. These types of valves have been put on the spotlight when different types of pipelines encountered problems like leakages which resulted to massive damages to infrastructure, environment, and people. The San Bruno tragedy (a natural gas pipeline ruptured which caused lives and property to be lost) pushed National Transportation Safety Board (NTSB) to recommend the installation of automated valves on natural gas pipelines but it authorized the Pipeline and Hazardous Materials Safety Administration (PHMSA) and the industry operators to further study which type of valve is most effective. Their study resulted in diverse opinions which boiled down to the fact that there are no hard and fast rules on which valve (ASVs or RCVs) is better because several factors need to be considered including the pipeline system, operator training and the topography. Looking for the best type of valves and developing the best regulations for ensuring everyone’s safety is still a work in progress. For the full article, click here

Pipeline News: The future of intelligent pigging services to expand

Monday, August 17th, 2015

A pipeline infrastructure is the most strategic and efficient method for countries/governments and companies to transport liquids and gases across huge distances. The increase of investments in such assets also represent a greater need for maintenance and troubleshooting methods. One way to protect this investment is to do maintenance with the use of intelligent pigging tools. A pig is a device that is inserted in pipelines where it travels together with the product (gas or oil) to do specific tasks within the pipelines. According to Future Market Insight (FMI), intelligent pigging services market is set to increase up to $826.5 million in 2025 with a compound annual growth rate of 6.3% over a 10-year period starting in 2015. They have also analyzed the key trends in the market (including the growing demand for small pigs and long-term contracts with OEMs/vendors) as well as key factors (including growth of the global oil and gas industry, stringent government regulations, and advancement in pipeline inspection technology).

Economic Impact of Investment in Pipeline Infrastructure

Thursday, August 13th, 2015

Natural gas is quickly overtaking the position of coal as the leading source of energy in the market with an annual consumption in 2012 totaling 25 trillion cubic feet. Approximately fifty percent of North America’s consumption is sourced locally and the remaining half is imported. This requires a system of pipeline, storage facilities and supply points to be setup domestically and has so far resulted in a network of about 305,000 miles of pipelines.

With the rise of demands from different sectors (household, commercial and industrial), the need for extensive infrastructure installations becomes more pressing. The forecast for 2025 is that investments on pipeline infrastructure will increase to $73.8 billion, which will provide employment, labor income, increased government revenues and input to GDP. This will also set a chain reaction of economic effects within the industry’s supply chain which benefits manufacturers of raw materials (like steel and machinery) as well as finished products (like pumps, compressors, reading instruments, etc.). As a whole, the increase demand results to a better job market for suppliers as they build up their work force, increased income and an increase in the demand of consumer goods and services forming a complete cycle of economic stimulation.

Pipelines would ease rail freight capacity for US farmers

Thursday, August 13th, 2015

During the 2014 harvest, the average corn farmer in North Dakota received US$10,000 less than the prevailing rate for the same crop in the market and resulted in a US$570 million profit cut for the region. The main reason for this loss is that rail freight transportation in America is highly congested due to the spike in rail transportation of crude oil. According to a study by the American Farm Bureau Federation (AFBF), the expansion of North America’s pipeline infrastructure (especially in the Bakken region) would alleviate the overburdened freight rail network and in effect improve services for farmers who are very dependent upon the rail freight system to move their products to market.

Since crude oil is more flexible when it comes to methods for transportation, moving the crude oil to the market using pipeline infrastructure would be more efficient and would also enhance the American energy security. The study used mathematical simulated scenarios on how expansion of any freight method reduces the bottleneck in delivering goods and as a byproduct it presented the increase of annual volume of grains transported by around 14 percent.

Global pipeline processing and pipeline services market – industry analysis, size, share, growth, trends and forecast shared in new research report

Wednesday, August 12th, 2015

As of 2014, with approximately 3,800,000 kilometres of pipelines used locally and globally, pipelines remain the most economical and practical way to transport large quantities of various kinds of products (such as oil, gas, chemicals and water) from drilling/production sites to the storage terminals and end-users. In order to optimize their performance, pipeline companies take on maintenance and troubleshooting activities known as pipeline processing and pipeline services. Pipeline processing includes activities such as hot tapping, leak detection and metering, pipe freezing, chemical cleaning, controlled bolting, hot oil flushing, and foam inerting among others. Pipeline services include pipeline cleaning and gauging, testing services, filling and flooding, dewatering, nitrogen purging, and vacuum drying. The demand for these two are increasing steadily as current markets like the US, Europe and Middle East (Russia, Ukraine, U.K, Netherlands, Germany and Saudi Arabia), and emerging ones like Asia Pacific, Latin America and Africa continue to grow due to pipeline projects that are in the construction and planning phase as well their importance in the expansion and maintenance of existing pipelines.

Advantages of Natural Gas Pipeline

Wednesday, August 12th, 2015

With the growing demand for cleaner and more sustainable options in today’s increasingly environmentally-conscious world, the need for natural gas has also continued to rise. And because of the fact that natural gas is widely available and burns cleaner than coal, we currently get 25 percent of our electricity from this resource. That number is steadily increasing because of the positive impact natural gas is having on the economy and environment: burning natural gas produces lower levels of carbon monoxide, carbon dioxide and nitrous oxide compared to coal and does not produce ash and other particulates (according to the Environmental Protection Agency). In mid-September, Atlantic Coast Pipeline will commence construction on a 550-mile natural gas pipeline spanning across three states which will enable 50 to 60-year-old coal plants to be retired. The Governor of Virginia, Terry McAuliffe, has shown his support for the project since the coal plants will be replaced with a safer and more efficient energy source with fewer emissions as an environmental benefit.

Landowners unable to terminate aging pipeline contracts

Thursday, August 6th, 2015

Landowners in Gonzales County who live on top of a 40-year-old pipeline are now battling Texas pipeline companies over easements that they thought were rightfully theirs. The pipeline runs for about 30-something miles, and is part of the state’s extensive network of oil and gas pipelines that were built before 1970, some of which haven’t been used for years (according to data from Pipeline and Hazardous Material Safety Administration). Landowners like Sarah “Sally” Birkner and her neighbors believed the pipes were abandoned because the pipeline company didn’t trim any of the overgrown brush and trees, posted signages above the line, or respond to requests to build or dig over the top of the pipeline. But legal experts say the companies are using the law to redefine use to hold on to the pipelines and the thin strips of land that run over them. By keeping an electrical current on the pipeline to prevent corrosion, the company’s ownership of the line and the land over it remained intact. Read the full story here…

NoPig: A New Inspection Technique For Non-Piggable Pipelines

Monday, August 3rd, 2015

The NoPig technique has been developed as a supplement/alternative for inspecting unpiggable pipelines around the world (including the thousands of kilometers found in Europe), which require some non-destructive evaluation techniques that can be applied without inserting inspection tools into the pipelines. Some of the other indirect techniques like DC voltage gradient or current mapping can only be used externally because they can detect coating damages but are unable to gather information regarding metal loss. The NoPig technique, which comprises of the measurement and analysis of the surrounding magnetic field induced by the AC current passed through the inspected pipeline from a special source, performed significantly higher than existing corrosion detection methods and could also detect metal loss. It has been used in experiments with natural and artificial metal loss defects under field and laboratory conditions, and has been successfully implemented across Europe and overseas for gas, oil and fuel pipelines.
