A critical step in ensuring that a pipeline is fit and healthy for operations is continuous scraping “cleaning” and frequent scraping inspection. If scraping activities are not properly performed, pipeline integrity can be at risk. In a case study, numerous networks of pipelines were found to be operated with different experiences and internal…

In the recent years, the “integrity” issue has become a popular topic with pipeline operators and the development companies. Generally, it means the use of more advanced diagnostics tools, the corrective interventions that are based on the results and advanced SCADA (Supervisory Control and Data Acquisition) application. The advanced technical…

Under this well-known slogan one should classify what can currently be observed in pipeline technology: Large TSO with their technology subsidiaries from Asia and Eastern Europe (e.g. Transneft, Sinopec and others) are pushing their way into the markets in North America and Western Europe. This development naturally has several facets: On the one…

Increasing investments in renewable energy resources has led, in recent years, to the significant growth of wind energy and an associated increase in wind farm installations in many countries. However, the installation of wind turbines has very often been completed in the absence of specific requirements and limitations (e.g. minimum safety…

Within the scope of the presented work, a simulation model was developed which completely depicts the buried pipeline and the surrounding soil. The model was validated using a number of analytical methods. The bedding conditions of the pipe trench are described by means of a standardized criterion which takes into account the filled soil type…

Requirements for pipeline leak detection systems increase continuously. In Germany the operation of leak detection systems is regulated by the TRFL (Technische Regel für Fernleitungen). Even though it is a national standard, it has international acceptance as for example API1175 recommendations follow the TRFL. In May 2017 an updated version of…

The construction, operation and maintenance of high-pressure gas pipelines require conscientious planning and execution, taking numerous aspects into account. The focus must always be on ensuring that the surrounding is not impaired and that the safety of people and the environment is not endangered. In order to guarantee this, the DVGW rules and…

Risk management is an essential element in the pipeline integrity management process. Risk management involves not only the estimation of risk profiles and comparison against tolerable criterion but also ensuring that measures to treat the risk are effectively assessed and implemented. Performing risk assessments can assist operators and engineers…

The foundation of BIL eG by 17 German pipeline companies from the chemical, high-pressure gas and mineral oil sectors on 15 June 2015 cleared the path for developing the national information system for pipeline enquiries, BIL. With the implementation of an internet portal and a database backend, at the start of 2016 BIL will provide the first cost…

In the construction of pipelines for the transport and storage of combustible, corrosive or toxic gases and water-polluting fluids, independent inspections by experts is an essential aspect of quality assurance which contributes significantly to the safety of these systems. This does not only apply to new projects, but also to modifications,…

What an outstandingly warm summer this had been. We hope you could enjoy the sun and recharge your energy levels. Maybe some of you spent time on the water, including passing wind turbines and crossing offshore pipelines. However, despite the warmth, parts of Europe have suffered from severe weather, like dryness, thunderstorms, and flooding. It…

Pipelines in ultra-deep water depth are generally associated with design and installation technical challenges. Research and development efforts to improve reliability and efficiency of subsea pipelines, keeping the associated risks within an accepted range, are still a must. Improvement of the pipe steel grade quality, manufacturing innovations,…

Applicability of a simplified pipe-soil interaction model on determining pipeline’s dynamic behaviour, once seabed support is lost due to seabed liquefaction, is evaluated over Oleoducto Central-Ocensa (central oil pipeline). Located in Colombia, South-America, this transportation line has 12.5km of subsea pipeline in the Gulf of Morrosquillo-…

The Nord Stream 2 pipeline will transport natural gas into the European Union (EU) to enhance the security of supply, support climate goals and strengthen the internal energy market. Running through the Baltic Sea, Nord Stream 2 will deliver natural gas directly from some of the world’s largest known reserves in Russia to the neighbouring EU gas…

Safety is a crucial issue in operational activities. When performing a hot work operation on a live pipeline, it is very important to isolate the pipeline to prevent any dangerous event. In this paper, a newly and innovatively designed approach has been presented which has been used to isolate a 32” and an 18” offshore and infield pipelines from…

Pipelines are the veins of a worldwide energy system, serving industry and clients with all kinds of liquids and hazardous fluids and gases. In the 1920s to 1950s they have been built with a commercial lifetime of 25 to 30 years, but today some of the systems are reaching their 100 years of operation anniversary. The main bulk of high pressure…
