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.

To provide a best practice approach aimed aimed at reducing delivery time and production costs and improving material quality, a joint industry project led by DNV GL resulted in a recommended practice for steel forgings in subsea applications. -
Created by the Institute for Energy Technology in Norway in 1979, Olga was the oil and gas industry’s first transient multiphase flow model. A source of national pride, the program has been declared one of the country’s most important innovations in recent decades.
-
In the realm of enabling technologies, multiphase flow modeling has proven to be one of the most important to the oil and gas industry. Without it, nearly all subsea wells would be too costly or dangerous to develop.
-
Subsea power demand is growing to support various processing loads, including pumps and compressors. This paper presents a modular direct-current electrical-power system that is designed for use in a subsea field with medium or long step-out distance

After severe damage in a typhoon, the Huizhou oil field in the South China Sea was back on production in 5.5 months. This paper reviews how this feat was accomplished.
-
Over the next 5 years Douglas-Westwood (DW) expect USD 122 billion to be spent on global subsea vessel operations—an increase of 64% compared with the previous 5-year period.
-
This paper summary focuses upon reporting new research-and-development (R&D) initiatives related to subsea processing and boosting offshore Brazil.
-
This paper focuses on the applicability of subsea-processing technology (SPT) using multiphase pumps (MPPs) to develop marginal fields commercially.
-
Subsea processing is a significant technology that presents and will continue to bring many challenges and opportunities to the industry.
-
This paper summarizes the results of a qualification program that included a multiphase, subsea-separation system for shallow-water applications.
