  1. 1. Navigating the Seas of Change: A Grounded Theory Analysis of the First Adopters of Wind Propulsion Technology in the Shipping Industry

    University essay from Lunds universitet/Institutionen för tjänstevetenskap

    Author : Sofia Laaksonen; Shazbah Shafi; [2023]
    Keywords : grounded theory; wind propulsion technology; shipping industry; sustainability; paradigm model; conditional consequential matrix; Social Sciences;

    Abstract : Study purpose: The maritime shipping industry, particularly the commercial sector, is a significant contributor to carbon emissions and environmental pollution. Various solutions are being proposed to enhance the sector's sustainability, including the adoption of wind propulsion technologies. READ MORE

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

    University essay from Lunds universitet/Institutionen för energivetenskaper

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

    Abstract : 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. READ MORE

  4. 3. Comparison of Achieved Fuel Savings on Ships by Different Wind Propulsion Systems Using a 3-DoF Resistance Model

    University essay from KTH/Marina system

    Author : Severi Sarsila; [2022]
    Keywords : ;

    Abstract : This thesis aims to determine how different wind propulsion systems should be sized in order to achieve comparable fuel savings. The selected wind propulsion systems for the comparison are Dynarig, rigid wing sail and rotor sail. To answer this question, a performance prediction program based on a 3 Degree of Freedom resistance model was developed. READ MORE

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

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

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

    Abstract : 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. READ MORE

  6. 5. Development of a CFD Boundary Condition to Simulate a Perforated Surface

    University essay from Umeå universitet/Institutionen för fysik

    Author : Medet Kiflemariam; [2021]
    Keywords : Computational Fluid Dynamics; CFD; Boundary Condition; Bleed; Aerospace Engineering; Aeronautical Engineering; Physics;

    Abstract : In aircraft with jet propulsion engine intakes at supersonic speed, strong pressure waves referred to as shockwaves occur, which may interact with any present boundary layers along the intake surface. The adverse pressure gradients associated with Shock Wave-Boundary Layer Interaction (SWBLI) may cause boundary layer flow separation, which can result in disturbances of the flow that can be harmful to the device or decrease engine performance.
