  1. 1. Probabilistic Added Wave Resistance Predictions for Design of RoPax Ferries

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

    Author : Jonathan Viinikka; [2023]
    Keywords : Added wave resistance in head waves; Roll-on Roll-off Passenger ferry; Probabilistic wave environment; Semi-empirical method; Adderat vågmotstånd i motsjö; Roll-on Roll-off Passagerar Fartyg; Probabilistiska vågförhållanden; Semiempiriska beräkningsmethoder;

    Abstract : This thesis investigates reasons for significant uncertainties in added wave resistance predictionsand how wave conditions can potentially affect the design of RoPax ferries. The objectiveis to find a suitable prediction method of added wave resistance for the RoPax ferry designapplication. READ MORE

  3. 2. System-level assessment and comparison of fast charging and battery swapping technologies for full electrification of Maritime vessels

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

    Author : Pradeepsakthi Ulipuram Kandasamy; [2023]
    Keywords : ;

    Abstract : This thesis focuses on the system-level assessment and comparison of fast charging and battery-swapping technologies for the full electrification of maritime vessels. The maritime industry is a significant contributor to global greenhouse gas emissions and reducing emissions from shipping is crucial for achieving a sustainable future. READ MORE

  4. 3. Propulsion modelling of a generic submarine propeller

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Gustav Boman; [2023]
    Keywords : OpenFOAM; CFD; actuator line model; rotor disk; actuator disk; INSEAN E1619; propeller;

    Abstract : Self propulsion modelling is important in order to accurately simulate ships and submarinesusing Computational Fluid Dynamics (CFD). However, fully resolved simulations of hull andpropeller geometries are computationally heavy and time consuming. As such there is a greatinterest in lower order CFD models of propellers. READ MORE

  5. 4. 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.

  6. 5. Accelerating the Green Transition - Investigating the Feasibility of E-Fuel Production Connected to a CHP Plant

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Johanna Scholtz; Alice Maillard; [2023]
    Keywords : CCU; CHP plant; e-fuels; e-methane; e-methanol; e-kerosene; Technology and Engineering;

    Abstract : The overall purpose of this thesis is to investigate the feasibility of producing electrofuels from CO2 and H2 in connection to a CHP plant equipped with carbon capture technology. This is done by investigating the production of e-methane, e-methanol and e-kerosene from captured CO2 and H2 produced from electrolysis. READ MORE
