Onshore/Offshore Facilities
This paper identifies opportunities and risks associated with repurposing an offshore oil and gas platform for green hydrogen production. Various technical scenarios were investigated for the case study platform, and their profitability was determined using economic calculations. In addition, all the submodels were compared with standard decommissioning costs for reco…
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.

This year gas is expected to look only a bit better, but after 2019 that is a relief. -
On the normally unmanned Valhall Flank West platform, the survey of a 1-year-old box boom pedestal crane featured auto-testing of the automatic overload protection system. A similar inspection program was performed on two knuckle boom cranes on a FPSO vessel in Skarv.

Monitoring of corrosion in process pipelines has always been of paramount importance in ensuring plant-asset integrity. Similarly, steam traps play an important role in ensuring steam quality and, thus, the integrity of critical assets in the plant.
-
A combination of computational-fluid-dynamics and finite-element modeling offers a potentially powerful tool for assessing and diagnosing multiphase-flow-induced vibration problems in hydrocarbon-production piping systems.
-
Innovative elements of digitalization and automation of workflows provide a new approach for better handling of slugging in subsea developments with long tiebacks, potentially optimizing production and limiting the amount of flaring.
