A Feasibility Study of Hydrogen Production at Hitra
(Bachelor thesis, 2020)Klimaendringer og global oppvarming krever omstillinger i flere sektorer. Spesielt transportsektoren bidrar med store klimagassutslipp, som skyldes bruken av fossilt drivstoff. Hydrogengass er en energibærer med høy spesifikk ... -
A Feasibility Study of Large Scale Wind Powered Hydrogen Production
(Bachelor thesis, 2021)Det er skiftende tider, og verden gjennomgår for tiden en omstilling fra en levemåte basert på fossile brenselskilder, til et fornybart og utslippsfritt samfunn. Land over hele verden viser handlingskraft i forbindelse med ... -
A feasibility study of wind powered hydrogen production at Fosen
(Master thesis, 2019)Hydrogen (di-hydrogen, H2) er et ettertraktet drivstoff fordi det er det vanligste og letteste stoffet i universet, med to til tre ganger høyere energitetthet enn tradisjonelle drivstoff. Hydrogen kan produsere energi og ... -
A Field Study of Reduced Axial Compressor Performance Deterioration through Online Washing and Air Intake Filtration Upgrade
(Doctoral theses at NTNU;2018:300, Doctoral thesis, 2018)Background Oil and gas production at several North Sea offshore installations is limited by the gas turbine power available, and any deterioration in gas turbine performance directly affects production rates. Fouling in ... -
A Finite Element Tool for Investigation of Vortex-Induced Vibration of Marine Risers
(Master thesis, 2014)Vortex-induced vibration (VIV) is a major design issue for all deep-water riser systemsoperating in regions where severe sea currents can be expected. This highly complexphenomenon has resulted in a great deal of experimental ... -
A First-Principles Study of the Al (001)/Fe(0-11) Interface
(Journal article; Peer reviewed, 2018)Two phase Stefan problem was solved using analytical method in cylindrical domain. To solve governing equations Eigen conditions were formulated by using separation of variable technique. Eigenvalues of the eigencondition ... -
A flexural isostasy model for the Pleistocene evolution of the Barents Sea bathymetry
(Journal article; Peer reviewed, 2017)The topographic relief of the Barents Sea was subjected to major changes during the past 1.5 million years mostly due to sediment redistribution driven by glacial activity. This paper addresses the problem of Pleistocene ... -
A flow path detection algorithm to improve leakage risk assessment through defective jet-grouted cut-off walls
(Master thesis, 2022)Jetpelevegger er en attraktiv løsning som en kunstig strømningsbarriere for å hindre uønsket strømning av grunnvann i situasjoner hvor tungt utstyr ikke kan anvendes. Sannsynligheten for ukontrollert strømning må begrenses ... -
A Fluid-Structure Interaction study of flexible net sheet in uniform flow A comparative study between experiments and CFD
(Master thesis, 2021)Offshore aquaculture is a growing field with enormous potential. However, due to harsh condition in these site leads to higher loads. To effectively predict the hydrodynamic behaviour of flexible net in these conditions ... -
A Forecasting Model for Wind using Measured Correlation
(Master thesis, 2012)Wind power is currently one of the fastest growing power generation sectors in the world. The intermittent and random nature of wind energy, however, poses difficulties when integrating it into the electricity grid. ... -
A Formal Safety Assessment for Cruise Vessels Along the Norwegian Coast
(Master thesis, 2021)Cruisebransjen vokser over hele verden, og har blitt en stor industri i Norge. Den er spådd å fortsette å ha en solid vekst de neste tiårene, hvor trenden er større skip som frakter flere passasjerer. Cruisetrafikk langs ... -
