Offshore/subsea systems
This paper reviews the motivation and development of response-based forecasting from the perspective of the authors, reviewing examples and processes that have served as validation and led to modeling refinement.
This paper compares traditional welded techniques, such as above-water repair methods and underwater hyperbaric welding, with the novel options offered by subsea connectors purposely developed for corrosion-resistant-alloy-clad pipelines.
This paper introduces a technology for offshore pipeline inspection centered on an autonomous robotic system equipped with underwater computer vision and edge-computing capabilities.

Because of extremely high internal and external pressures, unconventional separator designs must be used in ultradeepwater applications. A major operator has qualified a number of subsea technologies covering a wide range of operating conditions and fluid properties that encompass its subsea portfol -
The value of new technology, and its ROI, is examined. Understanding the value proposition is not a trivial matter. When investing in facilities technologies, we have traditionally looked to invest in those that will reduce Capex or Opex. But what about niche technologies?
-
This paper analyzes the various selection methods of integrated template structures (ITSs) for use in the Arctic environment. Operation and installation of subsea modules in the Barents Sea are also analyzed in this paper.
-
As production from mature basins onshore and in shallow water declines, the development of deepwater reserves has become vital. Consequently, production and Capex are expected to rise.

Linhua4-1 was China’s first tieback subsea development project. To develop this marginal oil field, a number of technical challenges were overcome through a series of new technologies, and their successful development and implementation.
-
As offshore development moves into deeper waters, harsh environments, and longer distances, the economic and practical advantages of moving as many components to the seafloor as possible has become a driving factor in technology development.
-
There is an increasing need to understand the strength and durability of subsea wellheads and conductors.
-
This paper demonstrates a design methodology that combines the API and American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessels Code (BPVC) for designing an example subsea pressure containing component for HP/HT conditions greater than 15,000 psi and 250°F.
-
Over the next decade, the number of electrically powered subsea systems in operation around the world will increase as companies adopt new technologies to produce oil and gas offshore more efficiently.
-
The world's first full-scale subsea gas compression system is the final stages of construction and is on schedule to be installed in the Åsgard gas field offshore Norway by year's end.
