In this case study, design-level depth to bedrock estimation for three short new pipeline alignments routed through southeastern...

..., estimates from a design-phase excavatability assessment conducted for a pipeline alignment routed through sedimentary rocks of the Canadian Cordillera are compared to actual construction observations including blasting records. Discrepancies and possible associated causes are then discussed...

... Abstract The safety and reliability of pipelines and piping components for any infrastructure network are crucial, particularly in regions prone to seismic activity. Since midstream facilities play a key role in the energy supply and water conveyance chains, safeguarding these assets from...

... control requirements as more time is spent in the ditch. This, in turn, elevates the risk associated with environmental threats such as the formation of hydrogen cracking in the welds due to poor moisture control. Quest Integrity and Colonial Pipeline executed a study utilizing detailed elastic-plastic...

... Abstract Pipeline in-line inspection (ILI) stands out as an effective approach for comprehensively understanding the conditions of pipelines. Matching of corrosion features detected in multiset pipeline ILI is an essential prerequisite to determining corrosion growth. State-of-the-art methods...

... Abstract This study investigates the burst capacity of pipelines containing pinhole-in-corrosion (PIC) defects through elastoplastic three-dimensional finite element analyses (FEA) and quantify the extent to which the burst capacity of the PIC defect is affected by sizes of the corresponding...

... Abstract Kuwait Oil Company (KOC) has been in operations since 1934 as a major upstream Oil & Gas Company with the main objective of exploring, producing & exporting Crude oil and Hydrocarbon Gases to customers across the globe. It operates several gas and liquid pipelines from 3″ to 60...

... but distinguishes itself by offering continuous monitoring capabilities. This is achieved through the use of permanent collars on pipelines, integrated into a system capable of automated data collection and upload to a cloud-based data management and visualization software. The information is delivered directly...

... Abstract Corrosion of buried, coated steel pipelines transporting natural gas is a significant source of methane emissions, from pipeline venting required for maintenance and repairs and from pipeline leaks and incidents. Corrosion of steel under field applied coatings is an important safety...

... Abstract Steel pipe bends manufactured by induction or cold bending processes have become increasingly prevalent in the oil and gas pipeline industry, often replacing fittings in many applications. However, the absence of clear specifications for the manufacturing of these types of bends...

... Abstract Buried pipelines serve as reliable conduits for transporting energy products such as oil, gas, and chemical fluids. Their pivotal role in facilitating the transportation of these resources underscores their substantial impact on businesses, economies, and the overall quality of life...

..., the compatibility of utilized materials must be investigated. First comprehensive studies on pipeline material hydrogen compatibility indicate that these materials can be applied to a certain extent. Nonetheless, the material compatibility is currently of high interest and focus of numerous research projects...

... Abstract Horizontal directional drilling (HDD) is a common pipeline installation method increasingly preferred to avoid challenging terrain, geohazards, and environmentally sensitive areas that would otherwise be encountered with conventionally trenched installations. However, HDD pipeline...

... Abstract An ongoing study is assessing the suitability of line pipe materials for use in gaseous hydrogen transmission pipelines. Previous publications present fracture and fatigue testing of the parent and seam weld centre line microstructures of an offshore 1970’s API 5L X60 grade SAW...

... Abstract In decarbonizing Canada’s energy systems, utilizing hydrogen as a low-carbon fuel is growing in interest, and repurposing in-service natural gas transmission pipelines to transport large volumes of hydrogen can be a key solution. Existing intraprovincial natural gas transmission...

... Abstract Transporting anhydrous ammonia by pipeline is receiving greater interest with global efforts to decarbonize and transition away from carbon-based energy. In the United States, there are currently over 2,000 miles (3,200 km) of anhydrous ammonia pipelines, which were constructed between...

...). Focusing on a hypothetical scenario closely resembling actual project requirements in the industry, the study evaluates three design options for hydrogen storage and transportation. Design Option 1 utilizes oversized pipelines, leveraging pipeline packing/unpacking mechanism, while Design Option 2 involves...
