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...
