  1. 1. Energy flows and potential energy development strategies in RoRo ports: A study based on the Port of Trelleborg

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Gabriele Gonzales; [2023]
    Nyckelord :RoRo Ports; Energy Flows; Energy Development; Energy Strategies; Renewable Energy; Ports; Energy Hub; Energy Storage; Hydrogen; Technology and Engineering;

    Sammanfattning : The recent push for decarbonization in the maritime sector presents an opportunity for ports to strengthen their position as energy hubs. This work studies the existing energy flows in the Port of Trelleborg, one of Europe's biggest roll-on, roll-off ports, and proposes some energy-related development strategies. LÄS MER

  3. 2. Experimental Investigation of the Aerodynamics of a Sailing Cargo Vessel with Four Rigid Wingsails under Unsteady Sailing Conditions

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Antonia Hillenbrand; [2022]
    Nyckelord :Experimental Aerodynamics; Pressure measurements; Sailing; Scale model testing; Trimming; Sea trial; Experimentell aerodynamik; Tryckmätning; Segling; Testning av skalamodeller; Trimning; Sjöprovning;

    Sammanfattning : Wind propulsion is a traditional way to propel ships over the oceans. In the recent development towards more sustainable shipping, sailing is considered in the industry again with high momentum. For a modern merchant ship, the aerodynamic forces generated on the particular rigging are unusual. LÄS MER

  4. 3. Performance Prediction Program for Wind-Assisted Cargo Ships

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Martina Reche Vilanova; [2020]
    Nyckelord :;

    Sammanfattning : Due to the accelerating need for decarbonization in the shipping sector, wind-assisted cargo shipsare able to play a key role in achieving the IMO 2050 targets on reducing the total annual GHGemissions from international shipping by at least 50%. The aim of this Master’s Thesis project is todevelop a Performance Prediction Program for wind-assisted cargo ships to contribute knowledgeon the performance of this technology. LÄS MER

  5. 4. Energy Sail Ships

    Kandidat-uppsats, KTH/Energiteknik

    Författare :Tagiadin Assenai; Oscar Hendey Bröte; [2020]
    Nyckelord :;

    Sammanfattning : Oceans offer a vast supply of energy through ever-present winds and currents. Offshore wind energy alone could provide many times the current global energy demand. One concept approach that aims to tap into these reserves are energy sail ship, wind powered vessel that take advantage of oceanic energy to produce and store harvested energy. LÄS MER

  7. 5. Putting a New Spin on Shipping

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :David Newman; [2020]
    Nyckelord :wind ship propulsion; Flettner rotor; human factors; technological innovation system; operational experience; Technology and Engineering; Social Sciences; Earth and Environmental Sciences;

    Sammanfattning : This thesis concerns Flettner rotors, a wind propulsion technology for commercial shipping which has recently gained momentum due to its ability to reduce fuel consumption, and consequently CO2 emissions, in a polluting sector of industry. Flettner rotors are able to reduce average fuel consumption by up to 20% and can be operated on a wide variety of ship types and sizes through both retrofit and installations on new builds. LÄS MER
