1. FPGA Based Control of Multiple Electric Machines for Marine Propulsion Systems
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : This master thesis addresses the control of electric propulsion motors in a marine context. The focus lies mainly on the implementation of field oriented control (FOC) in a field programmable gate array (FPGA). The hypothesis is that FPGAs provide performance advantages over microcontroller-based control solutions by enabling parallel processing. LÄS MER
2. Relationship between Fatigue Properties and Surface Treatment of Aluminum Alloy
H-uppsats,Sammanfattning : Corrosion has posed a significant challenge within the maritime sector for numerousyears. In the 21st century, bolstering the corrosion resistance of alloys, particularlyaluminum alloys, has become paramount. Aluminum alloys find widespread use inpropulsion systems, boat hulls, and cargo vessels. LÄS MER
3. Propulsion efficiency with energy saving devices for vessels
Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Sammanfattning : Due to global warming, all industries must do everything they can to prevent temperature increases. In this bachelor thesis, the reader will get a description of how the marine industry is tackling the environmental problem and more precisely what a vessel can be equipped with to reduce fuel consumption.

4. Influence of current harmonics on the degradation of the catalyst coated membrane in PEMFC
Master-uppsats, KTH/KemiteknikSammanfattning : Sjöfarten är idag dominerad av förbränningsmotorer som är beroende av fossila drivmedel. Elektrifiering är en av huvudstrategierna för att möjliggöra fossilfri energiförsörjning inom internationell sjöfart. LÄS MER
5. Hydroacoustic Modelling of Podded Propulsion System : Underwater Radiated Noise Prediction Using ANSYS
Master-uppsats, KTH/Teknisk mekanikSammanfattning : Ocean noise pollution is an invisible but growing threat. There are many sources of sound in the ocean but human underwater radiated noise, in particular from shipping is one of the most prominent one. Ocean noise pollution can interfere or sometimes even directly harm marine life. LÄS MER
