Influence of Offshore Wind Farms on Primary Production in the North Sea
(Master thesis, 2016-06-01)The less studied environmental consequences of power production from offshore wind energy on the marine ecosystem dynamics, are studied through investigation of response on primary production. An idealized wind farm ... -
Investigation of gaseous ammonia for NOx control by SCR on an experimental basis
(Master thesis, 2016-08-15)My dissertation argues which of the two reducing agents, urea or pure ammonia, is better suited for reducing NOx emissions in Marine SCR applications. While the question might seem straight forward, there are several upsides ... -
An Investigation of Single Wind Turbine Wakes with Static LiDAR Wind Profilers
(Master thesis, 2016-06-01)Three static LiDAR wind profilers were deployed during the seven month field experiment WINTWEX-W at ECN's test site in Wieringermeer. The campaign was focused on capturing the structure and dynamics of the wake of a NORDEX ... -

Konsepsjon, simulering og testing av en elektronisk styrt hydraulisk aktuator for styring av en motorventil
(Master thesis, 2018-08-23)Denne masteroppgaven tar for seg elektrohydraulisk styring av en motorventil i en medium speed motor. Det forsøkes å utnytte en eksisterende kamaksling til å drive en pumpe som skal gi trykk til en aktuator, slik at denne ... -
A Numerical approach for Ship Energy Analysis
(Master thesis, 2018-06-20)This master´s thesis has focused on energy analysis of ships and ship designs by developing a tool and a method for numerical analysis for evaluation of emissions, efficiency and costs. The overall focus has been on making ... -
A numerical estimate of the tidal energy in the Lofoten area
(Master thesis, 2014-05-28)In the following study the energy potential associated with tidal energy will be investigated. A depth integrated model based on the Navier Stokes equations and the continuity equation will be applied to simulate the tides ... -
Numerical Study of a Microturbine Combustor
(Master thesis, 2018-06-21)Microturbines are small-scale gas turbine engines with a power range of 20 to 500 kW, typically used for off-grid power generation or mechanical drive scenarios. The technology also shows potential in combination with ... -
Numerisk modellering av varmeoverskudd i grunnvarmeanlegg – Konsekvenser og forebyggende tiltak
(Master thesis, 2018-06-21)The emission of greenhouse gases must be reduced to meet the objectives of The Paris Agreement. Geothermal heat pumps (GSHP) can reduce energy consumption and emission of greenhouse gases in the building sector. When an ... -
Ocean Thermal Energy Conversion
(Master thesis, 2016-05-31)På grunn av verdens stadig økende behov for energi, samtidig som klimaproblemene har økt er det tydelig at flere tiltak må iverksettes. Ocean Thermal Energy Conversion er lovende fornybar energiteknologi som kan være med ... -
Optimization of the Offshore Wind Inter-Array Cable Layout problem using heuristic based algorithms
(Master thesis, 2018-06-13)The current work presents an in-exact solution method used to identify feasible, and less costly inter-array cable layout for offshore wind farms. The solution method developed has been built considering the interests of ... -
Sensitivity analysis of the dynamic response of floating wind turbines
(Master thesis, 2018-08-23)Development of offshore wind turbines shows a clear shift from the fixed-bottom turbines to the floating turbines. The reason for such tendency is due to the fact that moving towards the deep ocean will substantially limit ... -
Simulations of the Effect of Integrated Metal Nanoparticles on the Optical Absorptance of Perovskite Photovoltaic Solar Cells
(Master thesis, 2018-09-08)The negative effects from the use of fossil fuels that are evident in the ongoing climate change and pollution challenges necessitates a shift from fossil fuels to renewable energy technologies. The most promising of these ... -
A Solar Absorber Based on Metal Nanoparticles
(Master thesis, 2016-06-01)Metal nanoparticles (MNPs) exhibits unique optical properties often found in the visible spectrum of light. The key point of interest is the so-called Localized Surface Plasmon Resonance (LSPR) effect that arises within ... -
