Quantitative risk modelling of maintenance work on major offshore process equipment
(Journal article; Peer reviewed, 2018)Investigations of major offshore accidents show that both technical and non-technical factors have crucial effects on the accident sequences. Nonetheless, quantitative risk analyses (QRAs) have traditionally focused on the ... -
Quantitative seismic characterisation of CO2 at the Sleipner storage site, North Sea
(Journal article; Peer reviewed, 2017)Reliable quantification of carbon dioxide (CO2CO2) properties and saturation is crucial in the monitoring of CO2CO2 underground storage projects. We have focused on quantitative seismic characterization of CO2CO2 at the ... -
Quantitative Seismic Geomorphology of Cenozoic submarine channel system in the Canterbury Basin, Offshore New Zealand: Implications for paleoenvironment interpretation and hydrocarbon prospectivity
(Master thesis, 2019)Nowadays, high resolution 3D marine seismic reflection data have allowed to study the morphology of submarine channels (primary conduits to transfer sediment from shelf to the basin) to understand the sedimentary processes ... -
Quantitative Seismic Interpretation using Rock Physics Templates - case examples from the Zumba field
(Master thesis, 2016)A post drill inversion study was done by Avseth et al. (2016) after the dry well result from Zumba prospect. The AVO inversion failed in a graben setting, caused by a hard carbonate layer and associated refraction just ... -
Quantitative Seismic Monitoring
(Doctoral theses at NTNU;2022:127, Doctoral thesis, 2022)Seismic data is the main input for reservoir characterization in developing plays, when - in general - only conceptual geological models and few wells are available. When repeated over time, in a process called 4D seismic ... -
A quantitative ship risk model to select unannounced ship inspection - A tool to improve safety and environment?
(Master thesis, 2015)Norwegian Maritime Directorate has been worked with development of the risk-based inspection. The Directorate has established a method for risk assessment at a general level. However, they do not have any concrete method ... -
Quantitative spatial analysis of rockfalls from road inventories: a combined statistical and physical susceptibility model
(Journal article; Peer reviewed, 2014)Quantitative spatial analyses and statistical susceptibility assessments based on road inventories are often complicated due to the registration of impacts instead of source areas. A rockfall inventory from the Norwegian ... -
A quantitative study of salinity effect on water diffusion in n-alkane phases: from pore-scale experiments to molecular dynamic simulation
(Peer reviewed; Journal article, 2022)Numerous mechanisms have been proposed to untangle the effect of a low concentration of dissolved salts in the water flooding medium. One potential mechanism for enhanced oil movement is proposed with osmosis effect, ... -
Quantitative time lapse seismic analysis - rock physics, repeatability and inversion aspects
(Doctoral thesis at NTNU;2015:127, Doctoral thesis, 2015)Quantitative prediction of pressure as well as saturation effects from time-lapse seismic data is one of the topics of interest for geophysical society since the last decade. Time-lapse amplitude variation with offset ... -
Quantm som erstatning for tradisjonelle linjevalgsmetoder
(Master thesis, 2021)Quantm er et digitalt prosjekteringsverktøy fra teknologiselskapet Trimble som i de siste årene har fått mer og mer oppmerksomhet. Programmet skal angivelig gjøre valg og vurderinger av linjeføringer mer effektivt og ... -
Quartz Fine Particle Processing: Hydrophobic Aggregation by Shear Flocculation
(Peer reviewed; Journal article, 2023)This study investigates the hydrophobic aggregation of fine quartz particles through shear flocculation induced by dodecylamine in aqueous solutions. The effect of stirring speed, collector concentration, flocculation time, ... -
Quasi-cleavage hydrogen-assisted cracking path investigation by fractographic and side surface observations
(Journal article; Peer reviewed, 2019)Despite recent substantial advances in understanding of hydrogen embrittlement (HE), many important aspects of this widespread phenomenon remain a subject of debates. Particularly, remarkably different opinions have been ... -
Quasi-dynamic modelling of shared mooring lines for floating wind turbines
(Master thesis, 2022)The idea of shared mooring systems has been introduced in the offshore wind farm industry as an effort to lower the overall installation costs for floating offshore wind farms. The reason for building such plants is that ... -
Quasi-static Analyses of Slender Structures with Complex Cross-Sections using Explicit FEM Codes
(Master thesis, 2013)It has previously been done analyses to find global stiffness values of an umbilical cable, with mixed results or no results at all when subjected to bending. There have also been difficulties in finding a distinct stick-slip ... -
Quasi-static and dynamic behaviour of fillet welded connections
(Master thesis, 2016)Introduction Understanding the behaviour of the joints in a construction is crucial for structural engineers. In fact, the behaviour of steel joints exposed to static loading is well documented. Steel joints exposed to ... -
Quasi-static and dynamic indentation of offshore pipelines with and without multi-layer polymeric coating
(Journal article; Peer reviewed, 2018)Offshore pipelines are occasionally subjected to accidental impact loads from trawl gear or anchors, which may damage the pipe. In this study, a series of indentation experiments carried out on offshore steel pipes covered ... -
Quasi-Static and Dynamic Testing of Annealed Float Glass
(Journal article; Peer reviewed, 2018)Three different experimental set-ups were employed in the investigation of the fracture strength of annealed float glass. These included four-point bending tests on three different specimen sizes, and quasi-static and ... -
Quasi-static behavior of 3D printed lattice structures of various scales
(Peer reviewed; Journal article, 2021)Additive manufacturing technology has been playing an important role in industrial applications due to the potential capacities to fabricate complex geometries such as lattice structures, which are treated as outstanding ... -
Quasi-static behaviour of crash components with steel skins and polymer foam cores
(Journal article; Peer reviewed, 2018)Different types of crash components are extensively used by the automotive industry to absorb energy during car accidents. Such components typically consist of sandwich structures with thin metal or composite plates as ...
