... Abstract The BM-C-33 gas export pipeline, with its dimension of 22/24"OD, is one of the deepest large-OD pipelines under development. The pipeline design at such water depth is pushing the boundaries of current design codes, line pipe manufacturing capabilities and available installation...

... Abstract Flexible risers are an important component of offshore production systems of oil and gas. They are used to link subsea pipelines to floating installations, such as FPSOs. Flexible risers have been one of the preferred deepwater riser solutions in many regions of the world due...

... by a dedicated pipeline, to offset CO2-intensive production activities. The onshore CO2 stream is directed to the reinjection gas stream, enhancing the well-known capture and utilization (EOR) process that is already in course. As a proof-of-concept, the UNISIM-III model representing a fractured karst pre-salt...

... Abstract Flexible pipelines are widely used for oil and gas production in deep waters across the national territory. They have been designed to withstand a great amount of stress due to internal and external pressure, wave forces and their own weight. Over time, these pipelines may present...

... to the majority of offshore fields of production, also generating the necessity of construction of new pipelines to dispose of natural gas production; and the chemical characteristics of this natural gas, which presents a high level of contamination, such as carbon dioxide (CO2). According to Energy Research...

... Abstract When defining the subsea arrangement for a gas export system, a few options are available to connect a trunk gas pipeline to other pipelines or to FPUs, especially when there is uncertainty about future projects which may need to be connected to the export system. The objective...
