Investigation of Geotechnical Properties of TBM Spoil from the Follo Line Project
(Master thesis, 2018)In connection to the Follo line tunnel project this thesis investigate some of the existing experience on use of TBM spoil as a construction aggregate. Compaction control tests provided by Bane NOR for the deposit at Åsland ... -
Investigation of Grid Rent Business Models as Incentive for Demand-Side Management in Buildings - A case study on fully electric operated houses in Norway
(Master thesis, 2018)The increase in power drain on the grid, and increased penetration of inflexible, renewable energy sources, is creating a need for reduction in peak demand on the grid and matching the demand with supply, by demand-side ... -
Investigation of Heat Storage in Future Wood Stoves
(Master thesis, 2015)The objective of this work was to investigate heat storage in a heat storage unit utilizing a phase change material (PCM). This included finding an optimal geometry for heat transfer from the heat storage unit to the ... -
Investigation of high Temperature Energy Storage in NOrwegian Quick clay
(Master thesis, 2023)175 land, inkludert Norge, har forpliktet seg til å begrense det globale utslippet av klimagasser til under 2 grader gjennom Parisavtalen. Bærekraftig utvikling er avgjørende for å oppnå dette målet. Geotermiske konstruksjoner, ... -
Investigation of high-strength steel component subjected to stretch-bending: effect of forming history
(Journal article; Peer reviewed, 2014)The behaviour of a closed top-hat section made of Dogal 800 DP subjected to stretch-bending is studied both experimentally and numerically. The top-hat section was made by forming of a sheet using a FlexformTM fluid cell ... -
Investigation of Higher-Harmonic Wave Forces and Ringing Using CFD Simulations
(Chapter, 2018)Typical offshore structures are designed as tension-leg platforms or gravity based structures with cylindrical substructures. The interaction of waves with the vertical cylinders in high sea states can result in a resonant ... -
Investigation of Hook Load Behavior while Tripping Through Tight Wellbores
(Master thesis, 2011)Recognizing different HKL response patterns while tripping through different restrictions in the well can be a huge advantage in the sense that it can reduce downtime and stuck pipe incidents as it allows for right means ... -
Investigation of how Hydrophilic Silica Nanoparticles Affect Oil Recovery in Berea Sandstone: An Experimental Study
(Master thesis, 2014)Nanofluids, or nanoparticles dispersed in brine, has been launched as a promising enchaned oil recovery technique (EOR). Several coreflooding experiments were performed to investigate the effect of hydrophilic silica ... -
Investigation of how Silica Nanoparticle Adsorption Affects Wettability in Water-Wet Berea Sandstone: An Experimental Study
(Master thesis, 2013)Retention, or nanoparticle deposition, on the walls of porous media has been shown to cause alterations in rock properties, such as porosity and permeability. This thesis investigated the possible alterations in wetting ... -
investigation of hybrid power plant configurations for an offshore vessel with co-simulation approach
(Peer reviewed; Journal article, 2023)This work presents a full-system simulator consisting of a generic power system integrated with a vessel model and real-time capabilities. The whole system simulation facilitates evaluating the overall system performance ... -
