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 ... -
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 ... -
Low-level jet height’s impact on wind turbine loads: A case study
(Master thesis, 2023-06-01)Over the years, wind turbines have been steadily increasing in size, with newer models boasting larger dimensions. For instance, the diameter of an installed prototype offshore wind turbine in late 2022 was over 200 m, ... -
Microbial behavior and hydrogen consumption of Oleidesulfovibrio alaskensis - Implications for subsurface hydrogen storage
(Master thesis, 2023-06-01)To reduce global warming an energy transition going from fossil fuel to renewable energy is required and energy storage opportunities to store surplus electricity are needed. Hydrogen gas (H2) is an energy carrier and can ... -
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 ... -
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 ... -

Ombygging av en én-sylindret dieselmotor til dual fuel-drift og testing av alternative gassformede drivstoff
(Master thesis, 2020-06-26)Denne rapporten beskriver ombygging av en én-sylindret dieselmotor til dual fuel-drift, og videre testing av alternative gassformede drivstoff. I tillegg omhandler rapporten simuleringer gjort på samme motor ved hjelp av ... -
On the use of a new mathematical formulation for loads- and motion analysis of a mooring line
(Master thesis, 2023-11-20)This master thesis investigates the use of a new mathematical model for calculating loads and dynamic motion of a mooring line. Current industry standard mooring analysis tools uses a lumped parameter modelling approach. ... -
Optimal location of charging stations for electric vehicles
(Master thesis, 2023-11-20)The electrification of road transportation requires a massive investment in charging infrastructure to keep up with the demand for underway charging. A substantial research effort is put into the problem of finding optimal ... -
Optimization Models for Wake Mitigation in Floating Offshore Wind Farms
(Master thesis, 2024-06-03)Multiple methods for mitigating wake at floating offshore wind farms have been studied, and in this thesis yaw control and turbine repositioning are investigated. Four optimization models are proposed, yaw control, winch-based ... -
Optimization of Inter-Array Cable Layouts in Offshore Wind Farms Considering Reliability
