One of the main points to arise from discussions at April’s Banff Pipeline Workshop in Canada was the burgeoning crisis presented by the age and experience gaps in the pipeline industry, across the board and across the globe.
Brazil’s state-owned petroleum company Petrobras has awarded Saipem a contract to install two export pipelines in the country’s Pre-Salt region, located in the Atlantic Ocean.
The Mexican Government is in the process of selecting contractors for the construction of the 200 km Tamazunchale – San Luis de la Paz Pipeline, which will guarantee supply for power generation providing certainty for domestic and foreign investors.
Progress continues on the Greece–Italy Interconnector pipeline, which will ultimately form part of a new strategic pipeline system for the export of natural gas from the Middle East to Europe.
Saudi Aramco has awarded Saipem the engineering, procurement installation and commissioning contract for 580 km of pipelines as part of its Wasit Gas Programme in Saudi Arabia.
China National Petroleum Corporation has commenced welding on a crude oil pipeline which starts in Lanzhou, passes through the Gansu, Shaanxi, and Sichuan provinces, and ends in Pengzhou, northwest of Chengdu.
The Nigerian National Petroleum Corporation is moving ahead with two major gas pipelines, which will form the backbone of the country’s national energy infrastructure.
In Sub-Saharan Africa, the pipeline industry is gaining momentum as investment flows from private companies and development banks. Ensuring a reliable source of energy is integral to the development of other industries and a focus for governments and regional bodies. Pipelines International provides a snapshot of some of the pipeline projects aimed at fuelling these developing economies.
A properly backfilled pipeline trench can considerably extend a pipeline’s lifespan, making it an integral part of the construction process. Pipelines International asked major construction company Nacap why padding is so important and what it looks for in a padding machine to ensure that pipelines are protected.
For a more portable backfill solution, ST Pipeline recently used on the ALLU Screener Crusher during the construction of a 55 km natural gas pipeline in Washington County, Pennsylvania, USA.
Through the operation of the world’s longest crude oil and liquids transportation system and with a growing involvement in the natural gas transmission and midstream business, Enbridge continues to work toward its vision of becoming the leading energy delivery company in North America.
Challenging seabed topography, pipelay depths reaching 2,155 m below water level and deep water cable crossings were just some of the obstacles successfully navigated by the team of engineers and pipeline construction workers on the Medgaz Pipeline.
Regulators in the USA continue to ensure the safe construction and operation of pipelines with PIPA releasing new safety guidelines for governments and developers to better protect communities, and PHMSA announcing it is considering expanding leak detection requirements for onshore hazardous pipelines. In offshore regulation news, Norway-based DNV has launched a more detailed procedure for the qualification and validation of pipeline girth weld automated ultrasonic testing systems. A new certification programme has also been released that will establish guidance for pipeline assessment across Canada.
Pipelay vessels have enabled the exploitation of petroleum resources from the depths of the ocean for decades. Pipelines International follows the life of a pipelay vessel from the engineers’ initial etchings to the first voyage on the open sea.
Inline Services Inc has recently successfully completed runs of its newly designed Speed Control Pig, which is designed to be run in high-velocity pipelines where pigging speeds need to be reduced.
Until recently, one of the principal options for the tee installation process was to use welding to attach the tee to the live pipeline. While there are many years of experience behind hot-tapping operations, welding to live pipelines is not always suitable; high flow rates and pressures, as well as modern pipeline materials, present a number of disadvantages to this technique, which also involves potential hazards.

In recent years there have been significant developments in carbon capture and storage technology fuelled by the desire of many governments and communities to mitigate the release of CO2 into the atmosphere. Here, Pipelines International looks at the hot topics on the agenda for the Second International Forum on the Transportation of CO2, the only dedicated event organised each year to update the industry on the issues of transporting anthropogenic CO2.
Formed in 1972, the European Pipeline Research Group is a registered association of European pipe manufacturers and gas transmission companies. The group's recommendations have contributed to the improvement of pipeline practices worldwide and, in conjunction with two other associations, it continues to strive toward developing safer and more efficient pipelines.By John Tiratsoo, Pipelines International Editor-in-Chief
The June edition of the Journal of Pipeline Engineering is focusing on Arctic pipelines. Guest editor Professor Andrew Palmer has compiled varied and interesting papers on the subject, in addition to providing an insightful editorial.By Bill Bruce, Director of Welding & Materials Technology and Bill Amend, Principal Engineer in the Welding & Materials Technol
External corrosion is a major concern for pipeline operators. When areas of corrosion or other damage on operating pipelines are identified, there are significant economic and environmental incentives for performing repair without removing the pipeline from service. There are a variety of repair strategies available to pipeline operators for a given repair situation. This article discusses the use of non-metallic composite materials and full-encirclement steel sleeves.
During large-scale, cross-border military actions, fuel for aircraft and ground vehicles must be expeditiously transported to where it is needed. The NATO Pipeline System was constructed during the Cold War to supply Alliance forces with fuel, and spare capacity is currently available for civil use.
Industrial Scientific is now supplying the Ventis MX4 multi-gas detector, a lightweight, highly configurable instrument that is available with or without an integral pump. The Ventis detects up to four gases, including oxygen, combustible gases (LEL or CH4) and any two of the following toxic gases: CO, H2S, NO2, and SO2.
Borealis has introduced a new high-density polyethylene (HDPE) pipe ‘PE 100’ grade for the gas market, BorSafeHE3492-LS-H.
The Cat Rental Store recently launched a new website, where clients can find their nearest store, view rental rates if available, submit a request to rent equipment and view their dealers’ services and special offers.
GE’s Inspection Technologies business has released its USM Vision, an innovative, ultrasonic (UT) weld inspection system that allows non-UT trained specialists to gather reliable and accurate pipe weld inspection data for subsequent remote assessment by a suitably qualified UT expert.By John Tiratsoo, Pipelines International Editor-in-Chief
Over 200 delegates and 14 exhibitors recently converged in Houston, Texas, USA, to discuss new technology and innovative methods to solve the unpiggable pipeline puzzle.
After its 23rd successful year in Houston, the acclaimed Pipeline Pigging and Integrity Management Conference and Exhibition is coming to Europe! Pipelines International gives you three reasons to attend.By Dan Lentell, Membership/Business Development Manager, PIPE
The Case Studies Lecture Series, organised by the North East England Branch of the Professional Institute of Pipeliners, is introducing the unique insight and knowledge of leading experts from around the region.
