  1. 1. Climate Impact of Wind Turbine Production : Emissions from Material and Energy Usage for Onshore and Offshore Wind Turbines

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

    Author : Joel Arnelo; Maria Kolte; [2023]
    Keywords : Wind turbine production; Wind turbine components; Onshore and Offshore wind power; Wind power climate impact; Produktion av vindkraftverk; Vindkraftverk komponenter; Landbaserad och havsbaserad vindkraft; Klimatpåverkan vindkraft;

    Abstract : Wind power is a renewable energy source that is making great strides in the global energy sector. While wind power is a renewable energy source, it is not entirely free from carbon emissions. This is because the production of wind turbines is dependent on the use of energy, and as a result can emit large amounts of carbon dioxide. READ MORE

  3. 2. Review and Design of DC Electrical Field Measurement Systems and Related Developments : For Measurements Around HVDC Cable Terminations

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

    Author : Emil Bergvall; [2023]
    Keywords : DC Field Probe; Measurement Systems; Electric Fields; Cable Termination; Ion Drift; Conductivity; HVDC; Field Mill; Field Simulations; Positioning System; MEMS; Electro-Optics; DC Fält Prob; Mätsystem; Elektriska Fält; Kabelavslut; Jondrift; Ledningsförmåga; HVDC; Fältkvarn; Fält Simulationer; Positioneringsystem; MEMS; Elektro-Optik;

    Abstract : With power generation and consumption placed further away from each other, with for example increased offshore power production, the need for HVDC transmission systems increases. As voltage levels in the HVDC transmission system are raised, the losses can be decreased, enabling efficient power transfer over longer distances. READ MORE

  4. 3. Value chain analysis : Searching for upstream value-adding in the Kenyan seaweed industry

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Anton Dahlberg; [2022]
    Keywords : ;

    Abstract : Growing interest for seaweed derived products in industrial applications have driven demand for tropical seaweeds in recent decades. To take part of this development, Kenya has incorporated a target of expanding its existing yet small-scale seaweed industry through the Kenyan Blue Economy agenda. READ MORE

  5. 4. CFD Analysis of Water Replenishment Holes in an Offshore Wind Turbine Foundation

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Shubham Arvind Tupkar; Swetha Sappe Narasimhamurthy; [2022]
    Keywords : CFD; Wave Dynamics; Implicit LES; GABC; OpenFOAM; Stokes V; Monopile Foundation; Replenishment Holes;

    Abstract : The study presented in this thesis investigates the passive exchange of enclosed water with seawater in an offshore wind turbine foundation. This thesis was undertaken in collaboration with Vattenfall R&D, Älvkarleby, Sweden. The water exchange is studied by utilizing Computational Fluid Dynamics (CFD) simulations. READ MORE

  6. 5. Offshore Wind Power Foundations' Corrosion Protection Strategy : Anlysis remotely controlled corrosion protection system and comparison to traditional corrosion protection of offshore wind foundation

    University essay from Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

    Author : Mazen Alhamalawi; [2021]
    Keywords : natural potential; corrosion; corrosion protection system; GACP; ICCP and sacrificial anodes; naturlig potential; korrosion; korrosionsskyddssystem; GACP; ICCP och offeranoder;

    Abstract : När en metall är omgärdad av en elektrolyt, så som havsvatten, kommer det att byggas upp en naturlig potential. Det sker en elektronvandring mellan materialet och havsvattnet och ju större potentialskillnad desto större sannolikhet att metallen kommer korrodera. READ MORE
