Offshore/subsea systems
This paper presents a flexible, highly cost- and energy-efficient method of gas separation and CO₂ capture from many different gas mixtures with a large range of CO₂ concentrations.
This work introduces a novel predictive methodology combining historical metocean data with real-time riser analysis for shallow water dynamically positioned rig operations.
A shared digital mindset across subsurface, subsea, and drilling and wells is accelerating well planning at Vår Energi.

The component is part of a full subsea deepwater completion/intervention system being designed by Expro for use on the Chevron tieback. -
The project aims to power subsea equipment with wave power and subsea energy storage. The two technologies have been deployed in the seas off Orkney, Scotland, and have begun a test program where they will provide low-carbon power and communication to infrastructure.

The supermajor redefined its Mad Dog II development in three key ways: a blank-sheet redesign to cut costs, altering the way it works as a result of the COVID-19 pandemic, and a digital twin offering unique access to the asset from anywhere in the world.
-
Recent developments from Equinor and Murphy Oil Corp. offer hope that the industry is zeroing in the right approach to building megaprojects.
-
The drilling of the Berling field will begin in the third quarter of 2026, with gas and condensate production expected in 2028.
-
The contractor will see the delivery of its first subsea production systems to Azule Energy.
-
The Swiss-based company Hydromea announced advances in underwater optical modem technology and development of an underwater monitoring system capable of daily data sweeps remotely.
-
The authors describe coiled tubing operations that used a riser on a monohulled vessel already performing riserless interventions.
-
Production from the Dover field is expected to start in late 2024 or early 2025.
