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 ... -
Challenges and opportunities in tags and tag-related technical information management
(Masteroppgave/UIS-TN-IKM/2014;, Master thesis, 2014-06-16)The fact that many giant Norwegian oil and gas fields are in decline, and that these fields have reached their tail phase urges Oil and Gas (O&G) companies to focus on maintenance and modification projects to extend the ... -
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 ... -
Characterisation of extreme load responses of a 10-MW floating semi-submersible type wind turbine
(Peer reviewed; Journal article, 2023)The global average size of offshore wind turbines has increased steadily from 1.5 MW to 6 MW from 2000 to 2020. With this backdrop, the research community has recently looked at huge 10–15 MW class floating offshore wind ... -
Characterization of acoustic emission signals under 3-point bending test
(Peer reviewed; Journal article, 2021)This paper summarizes a master’s thesis project which explored whether the characteristics of Acoustic Emission Testing (AET) signals can be used to detect yielding in steel samples undergoing a three-point bending test. ... -
Choice of fuel system for the offshore support fleet
(Journal article; Peer reviewed, 2019)The stringent requirements of the IMO's emission regulations call for alternative fuels and new ways of powering ships. However, the IMO predicts that technology which could reduce ship emission to zero, will either not ... -
The classification and reutilisation of recycled asphalt pavement binder: Norwegian case study
(Peer reviewed; Journal article, 2022)With increased demand of asphalt pavement and limited binder and aggregate supply, the reutilisation of Recycled Asphalt Pavement (RAP) has gained more attention in pavement engineering from the environmental, sustainable, ... -
Coastal Erosion Due to Decreased Ice Coverage, Associated Increased Wave Action, and Permafrost Melting
(Chapter, 2018-11)It is broadly recognized that the Arctic area has become highly popular for hosting new activities and new infrastructure. This is due to the combination of the need of exploring new areas to satisfy the ever increased ... -
Combining Computational Fluid Dynamics and Gradient Boosting Regressor for Predicting Force Distribution on Horizontal Axis Wind Turbin
(Journal article, 2021)The blades of the horizontal axis wind turbine (HAWT) are generally subjected to significant forces resulting from the flow field around the blade. These forces are the main contributor of the flow-induced vibrations that ... -
Compaction and Fluid—Rock Interaction in Chalk Insight from Modelling and Data at Pore-, Core-, and Field-Scale
(Peer reviewed; Journal article, 2020)Water weakening is a phenomenon that is observed in high porosity chalk formations. The rock interacts with ions in injected water and additional deformation occurs. This important effect needs to be taken into account ... -
Comparative analysis of artificial neural network model and analysis of variance for predicting defect formation in plastic injection moulding processes
