A Matheuristic Algorithm for an Offshore Multi-period Location Routing Problem
(Master thesis, 2024-06-28)With the recent increase in energy production generated by offshore wind farms, regular maintenance is important for wind farm owners to ensure that they remain operational. Currently, maintenance tasks are performed by ... -
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 ... -
A POD-Based Reduced Order Model for Offshore Wind Applications, using LiDAR Measurements and WRF-PALM Simulations
(Master thesis, 2022-06-03)Wind flow fields within a wind farm, including wake dynamics, are a complex system of large degrees of freedom. The wake shape and velocity deficit downstream of a turbine may be calculated using numerical modeling, such ... -
A Pore-Scale Study on Cyclic Flows in Porous Underground Hydrogen Storage
(Master thesis, 2022-06-01)A solution for energy storage is needed to balance supply and demand in future energy markets with an increased share of fluctuating renewable wind and solar energy. A key enabler is large-scale, seasonal energy storage, ... -
A Short-Term Optimization Model for Routing and Scheduling of Maintenance on Offshore Wind Farms
(Master thesis, 2024-06-03)Drift og vedlikehold bidrar til en stor del av den totale kostnaden på havvindparker. Derfor er det et mål å minimere disse kostnadene, samt maksimere produksjonen på vindparken. I denne masteroppgaven blir det presentert ... -
