For pipelines with successive ILI runs the detected population of corrosion defects can be compared to identify both internal and external corrosion growth. Depending on the number of defects to be compared, the assessment can demand significant effort and expertise to ensure accurate and meaningful correlations between often very large ILI data…

The 40 bar regional gas transportation network of Gasunie Transport Services (GTS) consists of, in addition to pipelines, valve stations, pressure regulating and metering stations and gas receiving stations. The majority of these stations have been built in the period 1960-1980. This raises questions on the remaining technical life-time of these…

Leaks from oil pipelines, storage tank and other facilities can be disruptive, expensive and can cause significant damage to the environment. The consequences of such leaks have been well published in recent years, leading to increased political pressure on the industry to find improved ways of monitoring for leaks. According to data published by…

Third-party interference is widely documented as being a major cause of damage to buried pipelines. In addition to routine surveillance, maintaining a minimum depth of cover is recognized as a key means of mitigation against third-party interference. We know that the depth of cover over pipelines can change with time. Current techniques available…

Studies indicate that we in the international pipeline industry are heading for a shortage of well-trained engineers and scientists. On the one hand, this is due to the fact that in recent years there have been fewer and fewer young people starting engineering or scientific studies, and on the other hand to the fact that the scope of tasks has…

All professional engineers make a commitment to maintain and enhance their competence by undertaking ‘Continuing Professional Development (CPD)’. CPD is the process of managing, and documenting the skills, knowledge and experience that a member of staff gains, both formally and informally. It is not simply training (learning how to do something,…

Knowledge transfer from senior to junior pipeline specialists and attracting young pipeliners to our industry is a topic on the agenda of many Pipeline Events. The few events that the writer of this article has attended have at least addressed these challenges. During one of the venues, a participant stated that his company could not attract some…

The paper deals with Life Long Learning (Vocational Education and Training (VET) system) by providing adaptive learning resources for work-based learning in the water industry. The emphasis is on the presentation of concepts, methodology and media examples. The necessity to develop such a concept is directly connected to the huge qualification…

Companies that operate technical systems, e.g. the German gas transmission system operator ONTRAS Gastransport GmbH, must ensure operational safety at all times, that all associated procedures and processes comply with the applicable laws and regulations, and that the company is also prepared to react in case of emergencies. Haphazard trial and…

Gas pipeline systems are not necessarily designed and constructed in such a way that modern inline inspection methods can be used successfully. This applies in particular to older lines constructed around the second half of the last century. The consequences of this are expensive problems for many pipeline operators because the mechanical…

Pipeline DN 400 Opatovac-Slobodnica of the total length of 105 km, was constructed in 1968 and its original purpose was to transport oil from Opatovac terminal to an oil refinery near Slavonski Brod, Croatia. When it was constructed it was made in five sections. Four of them was already converted to pipeline for natural gas transmission but the…

Enhanced Oil Recovery (EOR) technology with injection of carbon dioxide (CO2) in production oil fields become common method of oil recovery increase. From the first commercial CO2 EOR injection project on the Kelly-Snyder Field in West Texas past more than 45 years. However, there can be significant corrosion management challenges resulting from…

There are thousands of unpiggable and challenging pipelines running through Europe alone. The integrity management of these pipelines requires nondestructive evaluation techniques, which can be applied without introducing inspection tools into pipelines. Pipeline diagnostics shall, therefore, be executed from above ground. Indirect approaches…

Pipeline inspection using intelligent pigs is currently the safest and most reliable way to detect relevant defects, to plan repairs and maintenance and to calculate the pipeline lifetime. However, there are still many pipeline systems on- and offshore which were never designed and built for conventional ILI tools and modifications would be…

Particularly in the 1940s and 1950s, gas pipeline systems were not necessarily designed and built with inline inspection in mind. As a result, mechanical configurations are encountered that cannot be inspected with currently available inspection equipment. Furthermore, operators are trying to reduce capital and operational expenses by merging…

A natural gas leakage was detected on the unpiggable high-pressure DN 600 pipeline Kasejovice – Mikulášov in Czech Republic after 50 years of operation. The pipeline was excavated and found to suffer from extensive corrosion; corrosion of a similar extent was also found when another section of the pipeline was excavated on the same location. The…

Pipelines are the most economic and secure transport systems for oil, gas, and other products. But they can rupture, leak, or be damaged or destroyed by improper operation, theft, cyberattacks, terrorism or sabotage. Every day, many millions of tons of liquids and gases are transported via overland pipelines or pipelines within facilities. As a…

A “lean model” that minimizes uncertainties by simulating only the necessary characteristics for batch tracking proves to be more accurate than complex models that make a plethora of assumptions in attempting to model every single characteristic of pipelines with extreme elevation changes and slack. Energy supply chains require energy companies…
