Cement properties characterization from a section retrieved from an oil production well after 33 years of downhole exposure
(Peer reviewed; Journal article, 2021)A unique data set has been constructed based on the study of class G cement recovered from an oil well on the Norwegian continental shelf. The cement was placed between two casing sections and submitted to downhole conditions ... -
Certification as support for resilience? Behind the curtains of a certification body — a qualitative study
(Peer reviewed; Journal article, 2020)Certification in healthcare often involves independent private sector bodies performing legally required or voluntary external assurance activities. These certification practices are embedded in international standards ... -

Certify or not? The effect of the MSC certification on the ex-vessel prices for Atlantic cod in Norway
(Peer reviewed; Journal article, 2023-07)There is strong evidence that ecolabeled seafood commands a price premium in the retail market in Northern European countries. At the same time, there is significant uncertainty as to whether these markups are passed on ... -

Cfd analysis of low frequency oscillations in Newtonian and non-Newtonian fluids in a vertical pipe
(Peer reviewed; Journal article, 2019)The effect of vertically imposed, low frequency oscillations on the rheology of shear-thinning non- Newtonian fluids are studied numerically by computational fluid dynamics (CFD). Both Newtonian (water) and inelastic ... -
CFD investigation of blind-tee effects on flow mixing mechanism in subsea pipelines
(Peer reviewed; Journal article, 2022)Blind tees are widely used in subsea pipelines to enhance the mixing conditions of oil and gas products, but their structural design still relies on experience. In this paper, a series of numerical investigations have been ... -
CFD Investigation on Hydrodynamic Resistance of a Novel Subsea Shuttle Tanker
(Peer reviewed; Journal article, 2021-12)The Subsea Shuttle Tanker (SST) was proposed by Equinor as an alternative to subsea pipelines and surface tankers for the transportation of liquid carbon dioxide (CO2) from existing offshore/land facilities to marginal ... -
CFD investigation on scour beneath different configurations of piggyback pipelines under steady current flow
(Peer reviewed; Journal article, 2022)Scour beneath piggyback pipelines laid on a sandy seabed is numerically investigated by solving two-dimensional (2D) Unsteady Reynolds-averaged Navier-Stokes (URANS) equations. The fluid flow and the sediment transport are ... -
CFD investigations of scour beneath a submarine pipeline with the effect of upward seepage
(Peer reviewed; Journal article, 2020-12)A numerical model of scour beneath subsea structures considering the effect of upward seepage in the seabed is proposed. A small seepage can cause significant changes to the hydrodynamic force on the bed surface and stability ... -
CFD simulations of a suspension bridge deck for different deck shapes with railings and vortex mitigating devices
(Peer reviewed; Journal article, 2019)Aerodynamic response of a single-box suspension bridge girder is investigated using CFD simulations. The importance of including railings and vortex mitigating devices such as guide vanes and a spoiler in the simulations ... -
CFD Simulations of the Propagation of Free-Surface Waves Past Two Side-By-Side Fixed Squares with a Narrow Gap
(Peer reviewed; Journal article, 2019)Two-dimensional computational fluid dynamics (CFD) simulations are carried out to investigate the gap resonance phenomenon that occurs when free-surface waves travel past twin squares in tandem. The volume of fluid method ... -
CFD simulations of violent breaking wave impacts on a vertical wall using a two-phase compressible solver
(Peer reviewed; Journal article, 2019)Four different types of breaking wave impacts on a vertical wall are simulated using a two-dimensional two-phase Computational Fluid Dynamic (CFD) model. Air is considered as an isentropic ideal gas without solving an ... -
Chad. Realpolitik and Aspirational Deprivation
(Chapter, 2021)Chadians have experienced harsh governance and personal rule since colonization. Between independence in 1960 and the coup d’état in 1990 that brought President Déby to power, violent conflicts, and civil war continuously ... -
Challenge your Brain. Blogging during the COVID Lockdown as a Way to Enhance Well-Being and Cognitive Reserve in an Older Population
(Peer reviewed; Journal article, 2022-06)Background: The lockdown linked with COVID-19 restrictions has been reported to have severe consequences at an emotional and cognitive level, this was especially true for vulnerable populations, such as the older adults. ... -
Challenges and opportunities of marine propulsion with alternative fuels
(Peer reviewed; Journal article, 2021-06)The increasingly stringent shipping emissions regulations and global decarbonisation movement have prompted the adoption of alternative fuels in the shipping industry. This review presents the performance results and ... -
Challenges and opportunities: impacts of COVID-19 on Norwegian seafood exports
(Peer reviewed; Journal article, 2022)A rapidly growing literature shows that COVID-19 and the measures to contain the spread of the virus can have significant market impacts for seafood. These can be interruptions of production, or reductions in demand directly ... -
Challenges Associated with Creeping Disasters in Disaster Risk Science and Practice: Considering Disaster Onset Dynamics
(Peer reviewed; Journal article, 2022-01)In this article, we set out to reconcile a general conceptualization of disaster temporalities by drawing on the epitome example of a creeping disaster, namely famine. Our argument is driven by the recognition that slowly ... -
The challenges experts face during creeping crises: the curse of complacency
(Peer reviewed; Journal article, 2024)The policy literature has generally conceptualised crises as urgent public threats with clearly demarcated ‘focusing events’. Consequently, most studies have identified the main challenges faced by expert agencies involved ...
