Future Abrupt Changes in Winter Barents Sea Ice Area
(Master thesis, 2021-06-01)The Barents Sea is an area of strong anthropogenic winter sea ice loss that is superimposed by pronounced internal variability on interannual to multidecadal timescales. This internal variability represents a source of ... -
Oil Spill Modeling in Sea Ice Covered Ocean
(Master thesis, 2021-06-01)The ongoing reduction in extent and thickness of sea ice in the Arctic allows the expansion of shipping activity and oil exploration in the high north, and with that a potential increased risk of oil spill in ice covered ... -
Vertical diffusivity and oxygen concentrations in a fjord basin - A case study of the deep basin in Masfjorden
(Master thesis, 2021-06-01)The basin layer in a sill fjord is isolated from the coast, and may become hypoxic or anoxic if the renewal frequency is low. Deep water renewals and vertical mixing are the physical processes which affects the oxygen ... -

Control of Doubly Fed Asynchronous Generators for Wind Power Application
(Master thesis, 2021-06-01)This thesis researches and develops a Doubly Fed Induction Generator (DFIG) model suitable for a university lab environment. DFIGs have attracted significant amount of research, as it is one of the leading generator systems ... -
Bidirectional DC-DC Converter for Supercapacitor as DC-bus Stabilization Element
(Master thesis, 2021-06-01)The demand for renewable energy from wind and solar is increasing. These energy sources are intermittent and unpredictable to a degree and require a stable but fast responding DCgrid. This is achieved by extending the ... -
Bidirectional DC-DC Converter For Charging Batteries of Electric Vehicles
(Master thesis, 2021-06-01)The popularity of electric vehicles has seen significant growth in the latest years. More electric vehicles are connected to the grid, and the load is increased consequently. The electric vehicle battery can be employed ... -
Numerical Investigation of a Radially Cooled Turbine Guide Vane Using Air and Steam as a Cooling Medium
(Master thesis, 2021-06-01)Gas turbine performance is closely linked to the turbine inlet temperature, which in turn is limited by the turbine guide vanes ability to withstand the massive thermal loads. To improve the efficiency in modern high-temperature ... -
Evaluering av potensiale for hybride fremdriftsløsninger i fritidsbåter
(Master thesis, 2021-06-01)Evaluering av hybriddrift for fritidsbåter av typen snekke og sjark med fartspotensiale 0 til 9 knop. Bruk av dataverktøy som Ricardo IGNITE og Excel for å se på effektbehov, forbruk og rekkevidde ved hybriddrift -
A NAWDEX case study: Water vapor transport in atmospheric rivers and quantifying hand over of moisture between extratropical cyclones
(Master thesis, 2020-10-31)Meridional water vapor transport occurs predominantly within the warm sector of extratropical cyclones. The warm sector is seperated by the cyclone's warm front ahead, and the cold front behind. In this region the warm ... -

Investigation of the dynamic response of a spar FOWT, and its sensitivity to variations in draft
(Master thesis, 2020-06-30)The objective of this thesis is to investigate how the dynamic properties of a spar supported FOWT change when the draft is reduced, and what draft is needed in order to support a 10 MW wind turbine. Design solutions of ... -
Miljøpåvirkninger fra produksjon og bruk av hydrogen i maritim transport
(Master thesis, 2020-07-01)I denne studien er hydrogen foreslått som et alternativt drivstoff for maritim transport. Miljøpåvirkninger fra å erstatte konvensjonelle fossile brensler i sjøtransport med hydrogen vurderes ved å utføre en livssyklusvurdering ... -

Long-term changes in the Nordic Seas' hydrographic structure and overflow waters
(Master thesis, 2020-06-30)A collection of historical hydrographic data was used to examine the hydrographic properties of the water masses in the Nordic Seas from 1950 to 2018, with particular focus on the dense overflows from the Nordic Seas. ... -
Life cycle assessment of hydrogen fuel in aviation
(Master thesis, 2020-07-01)The aviation sector emits 2% of the global emissions caused by transportation. This is a problem for our global climate and has also shown to be an issue for the public after the Swedish boycott of airtravel, inspired by ... -
Tidal forcing and internal tide energetics around Svalbard: a numerical study
(Master thesis, 2020-06-27)The hydrostatic and linear Regional Ocean Modeling System (ROMS) is used to examine the tidal forcing and the resulting baroclinic response and energetics of internal tides generated around Svalbard in the Arctic Ocean. ... -
