  1. 1. FPGA Based Control of Multiple Electric Machines for Marine Propulsion Systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Simon Weideskog; [2024]
    Keywords : FPGA; Field Oriented Control; BLDC; SVPWM; SMO; Electric Drives; Electric Machines; Sliding Mode Observer; Marine Propulsion; Multiple Machines; Boat Motor; Fältorienterad styrning; marin framdrivning; elektriska drivsystem; elmaskiner; flertal maskiner; båtmotor;

    Abstract : 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. READ MORE

  3. 2. Propulsion efficiency with energy saving devices for vessels

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Samuel Östlund; [2023]
    Keywords : ESD; Energy saving device; Maritime; Kongsberg; Pre-swirl stator;

    Abstract : 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.

    Abstract : Maritime transportation emits about 3% of global greenhouse gas, International Maritime Organization (IMO) aims to reduce shipping’s emissions by 50% with respect to 2008 levels. Proton exchange membrane fuel cells (PEMFCs) are considered among the most promising clean technologies for decarbonizing the maritime sector. READ MORE

  6. 5. Alternative fuels for Swedish short sea shipping and inland waterways: Techno-economic study

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Julien Maszelin; [2022]
    Keywords : Alternative fuels Comparison Short sea shipping Inland waterways Sweden Biofuels Fischer-Tropsch Methanol Hydrogen Ammonia Fossil fuels Sustainable transportation;

    Abstract : Climate change is raising huge challenges for all industries worldwide. It is mainly due to anthropogenic activity and energy consumption which is the cause for emissions of greenhouse gas (GHG) among other environmental impacts and is expected to have huge impact on our societies globally.
