Seismic Response of Wind Turbines: Dynamic Analysis of a Wind Turbine in Horizontal and Vertical Direction - Subject to Earthquake, Wind & SSI
(Master thesis, 2013)For a numerical model of a 5-MW wind turbine, it is shown that vertical excitation from earthquake can produce severe response in the upper parts of the tower. Furthermore, for horizontal excitation it is shown that mainly ... -
Seismic Response of Wind Turbines: Time Domain Simulations Including SSI
(Master thesis, 2014)This thesis presents the time-domain seismic response of a parked wind turbine with a skirted foundation exposed to soil-structure interaction. The wind turbine is discretized using the finite element program ABAQUS/CAE ... -
Seismic Response of Wind Turbines: Time domain simulations, including SSI
(Master thesis, 2014)In this study, a numerical model of a 5MW offshore wind turbine on a monopile foundation was created in order to calculate the dynamic response of the structure including soil-structure interaction. The main focus was to ... -
Seismic sedimentology of triassic channel complex in the Barents Sea
(Master thesis, 2014)The Barents Sea area is located in the Arctic region, categorized as a marginal sea of the Arctic Ocean. The average of water depth is between 230 meters to 1500 meters, bordered by the shelf edge towards the Norwegian ... -
Seismic Shot Processing on GPU
(Master thesis, 2009)Today s petroleum industry demand an ever increasing amount of compu- tational resources. Seismic processing applications in use by these types of companies have generally been using large clusters of compute nodes, whose ... -
Seismic Signature in Fractured Reservoir
(Master thesis, 2019)Anisotropy in large parts of the earth's crust, particularly in sedimentary basins is well modeled by orthorhombic (ORT) symmetry. Schoenberg and Helbig (1997) introduced the orthorhombic medium as a combination of vertical ... -
Seismic signatures of effective anisotropic media based on well-log data
(Master thesis, 2023)Med utgangspunkt i masterspesialiseringsprosjektet TPG4570 ble denne masteroppgaverapporten skrevet. Noen teoretiske deler ble hentet fra fordypningsprosjektet, og det ble gitt referanser til delene som ble brukt. Målet ... -
Seismic signatures of fluid substitution in fractured media
(Master thesis, 2019)Seismic response to the fluid substitution of oil with water and CO2 in a reservoir is analysed. A model consisting of horizontal layers based on the upscaling of well log data is studied. An interval of the model is ... -
Seismic signatures of vertically fractured media
(Master thesis, 2019)Natural fractures are essential elements which can be commonly observed in reservoirs. The saying that "All reservoirs should be considered fractured until proven otherwise. (Narr et al., 2006)" is the best portrayal of ... -
Seismic Stratigraphic Interpretation of Late Palaeozoic Carbonates and Paleogeography of the Loppa High.
(Master thesis, 2016)This thesis presents a detailed study of Late Palaeozoic stratigraphic successions on the Loppa High using seismic 2D and 3D data and well logs. Four intervals of interest have been mapped using carbonate stratigraphy ... -
Seismic Study of the Outer Vøring Margin
(Master thesis, 2013)Rifting between Norway and Greenland culminated in Late Paleocene - Early Eocene when the continents of Greenland and Eurasia separated through seafloor spreading. This seafloor spreading was accompanied by voluminous ... -
Seismic Wave Attenuation in Partially Saturated Sandstone and AVO Analysis for Carbon Dioxide Quantification at Sleipner
(Master thesis, 2017)Sleipner field (North Sea) is the first largest CO2 storage site, where the Carbon Dioxide is reinjected into the Utsira Sandstone. The main aim of this work is to obtain an estimate of the CO2 saturation by using AVO ... -
Seismic wave modelling on GPU clusters
(Master thesis, 2019)Vi utvikler et program for å simulere seismiske bølger på GPU-klynger ved hjelp av CUDA og MPI. Ved å bruke spektralelementmetoden til å løse den elastiske bølgelikningen i 3D kan problemet paralleliseres og løses effektivt. ... -

Seismically guided CO2 storage resource estimation - A case example from the Smeaheia site in the Norwegian North Sea
(Master thesis, 2022)Ettersom CO2 i atmosfæren når nye rekorder, krever det internasjonale samfunnet en betydelig reduksjon av utslippsgasser. Karbonfangst og -lagring (CCS) er en viktig bidragsyter i denne innsatsen. For å oppfylle målet om ... -
Seismisk dimensjonering av strukturer ved hjelp av ikke-lineære modeller
(Master thesis, 2014)Det er ingen tvil om at Fibermetoden er den mest nøyaktige metoden for beregning av ikke-lineær seismisk respons. Fibermetodens evne til å fordele inelastisitet over tverrsnitt bestående av komponenter med forskjellige ... -
Seismisk inversjon ved bruk av genetiske algoritmer
(Master thesis, 2006)Det er ønskelig med nøyaktig informasjon om fysiske egenskaper som beskriver havbunnen for å kunne modellere akustisk utbredelse i vannet. Det har i denne oppgaven blitt sett på global inversjon av geoakustiske parametere. ... -
Seizure Precipitants
(Doctoral theses at NTNU;2017:214, Doctoral thesis, 2017)In the comprehensive management of epilepsy, both preventive pharmacological treatment and awareness of possible seizure precipitating factors are important. The true cause of seizure generation is often hard to disentangle, ...
