Artificial Intelligence in the Design of Offshore Pipelines against Geohazards

National Technical University of Athens
National Technical University of Athens
Depending on the local site conditions (i.e. bathymetry, geomorphology, geology), an offshore geohazard may have a detrimental impact on an offshore high-pressure gas pipeline during its lifetime. This fact is more pronounced in areas characterized by seismicity and the associated earthquake-related geohazards. Therefore, the design of an offshore...

Spec Breaks: Application of Codes for Launchers and Receivers

T.D. Williamson
T.D. Williamson
Safety and compliance are priorities for the design and operation of pipeline pig launchers and receivers, also known as traps. During design, different codes and standards can be applied depending on the product that will be transported and where the equipment will be located. Because of code interpretation, an operator or equipment provider may...

The Sivas Gypsum Karst - Implications for Routing, Construction and Operation of the Trans Anatolian Natural Gas Pipeline

 ILF Consulting Engineers Austria & TANAP
ILF Consulting Engineers Austria & TANAP
The TANAP route runs 92 km through one of the world´s largest gypsum karst terrains, covering an area of 2140km² (Günay 2002; Doğan & Yeşilyurt 2019) located in the Turkish Province of Sivas. A fantastic place for the geologist but a big challenge for the routing and construction of a pipeline. Based on the morphology a karst classification...

Trenchless pipeline installations in European key projects

For the gas supply in Europe, a reliable pipeline network has the highest priority. Besides the construction of the main supply routes, the fast and safe installation of the regional country-specific distribution networks play a key role. Different points of view of all involved parties have to be considered when it comes to the planning of routes...

STREICHER launches fully-electric driven HDD rig - An intelligent and eco-sensitive solution to decarbonize the job-site footprint

Max Streicher GmbH & Co. KG aA
In recent years, the issues of the environmental protection and nature conservation - and thus the question of regenerative energy sources - have become particularly important. STREICHER also holds the objective to reduce CO2 emissions in the future in order to reduce the ecological footprint. Therefore, the group has made it a primary objective to...

Current View of Design and Evaluation of Sulfur Pipelines

Current View of Design and Evaluation of Sulfur Pipelines
The global production of natural gas is increasing continuously leading to development of gas fields with challenging contents such as sour gas containing highly toxic hydrogen sulfide. In a process called “gas sweetening” the hydrogen sulfide is removed, yielding liquid elemental sulfur. This substance is not just a by- product of the natural gas...

River crossing and water crossing survey by airborne bathymetric laser scanning - Case study TAG

River crossing and water crossing survey by airborne bathymetric laser scanning - Case study TAG
Airborne bathymetric laser scanning delivers the same results as regular airborne laser scanning, but with one major difference, this technology is able to penetrate water. The technology has matured through the past years, meanwhile it is used for the bathymetric survey of lakes, harbors, coastal shore lines and rivers. The Trans Austria...

Pipelines may observe significant axial displacement or force at the ends that tie-in with connected equipment and/or facilities. These axial forces are mainly driven by pipe size, temperature, pressure, length and surrounding soils or supports, and can have devastating effects on connecting facilities if not properly accommodated in the design...
