...field of wind turbine wake estimation, that again leads to uncertainties in the load and power estimation of wake affected turbines. Recent studies have shown significant effects of floater motions on power production and emphasizes the need for the effect to be integrated into existing wind farm energy...
...development and increasing ship traffic, coastlines are at greater risk of oil pollution resulting from these operations. Fjords are one feature common throughout the arctic, with many dotting the coast of Norway. While these fjords often remain ice free year-round, some fjords in both southern and northern...
There are hundreds of PAH compounds, and some of them are known to have negative effect on nature and humans if emitted to the environment. On a regulatory level, the long-term goal is to eliminate PAH emissions. It is important to measure PAH correctly to understand where these pollutants come from...
...refrigerants and should also contribute to increasing the overall energy efficiency of the ship. Against this background, the present diploma thesis deals with the design of a CO2 refrigeration system to supply the air-conditioning units on board of a cruise ship. The characteristics and peculiarities...
This paper presents the methodology and main results of the most recent Norwegian customer survey on consumer valuation of interruptions and voltage problems. The survey provided cost estimates that have been incorporated in the quality of supply regulation, in terms of the cost of energy not supplied...
...of CO2-mixtures are prerequisites for development of more accurate models and hence more precise design of CO2 capture and storage (CCS) processes. A literature survey was conducted on both the available experimental data and the theoretical models associated with the transport properties of CO2-mixtures...
This study investigates the impact of operational fluctuations and uncertainties on the design and expected cost of ship-based CO2 transport. The model analysis is based on a two-stage stochastic investment model for a single-source single-sink CCS value chain with a ship-based transport system. The...
...base for evaporation of flowing isobutane and propylene in compact internally enhanced surfaces is extended by experimental tests in two microfinned tubes and a smooth tube. The outer diameter for all of the test tubes was 5 mm. Heat transfer coefficient and pressure drop were compared for both fluids...
This report elaborates on the toolchains applied for generation scheduling in the two countries Norway and Brazil. Both countries have vast hydropower resources, with numerous geographically widespread and complex reservoir systems. Although the underlying objective of the scheduling is essentially the same...
Pyrolysis conditions in charcoal production affect yields, properties, and further use of charcoal. Reactivity is a critical property when using charcoal as an alternative to fossil coal and coke, as fuel or reductant, in different industrial processes. This work aimed to obtain a holistic understanding...
