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 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...

Gas transmission pipelines belong to the critical infrastructure – they are essential for the energy supply of the industry and public households. International and national statistics1,2 show a continuous decrease in the number of events per 1000 km pipeline length as a result of a permanent increase in Technical Safety during the last thirty...

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...

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...

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...

The guarantee of a high safety standard of the gas infrastructure must be the highest goal of economic and operational action within the framework of proceeding national and European regulation and the organisational changes interrelated in the companies [1]. At the beginning of the 1990th DVGW, the German Association for Gas and Water, developed...

An extensive gas infrastructure system crisscrossing Germany ensures the high reliability of supply of heat and electricity to the civilian population, of process heat/heat energy and natural gas as a raw material for organic chemistry to the industry, of highly efficient primary energies to power plants, and of alternative environmentally friendly...

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...

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...

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...

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...

The paper describes development of In-Line Inspection (ILI) tools and equipment for deployment in 500+m water depth offshore oil production pipelines. Various design challenges were posed by the operational conditions and the pipeline operator. A joint development project is described in which 3P Services and Total E&P define the necessary tool...

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...
