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

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

    Författare :Jonathan Viinikka; [2023]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

    Författare :Emil Eliasson; William Dahl; [2023]
    Nyckelord :biofouling; aquatic species; invasive alien species; ship hull; vessel; ship; Baltic sea; Baltic; natural environment; new research; Ekosystem; Fartygsskrov; Hav; Biofouling; Biologisk påväxt; Östersjön; Organisationer; Invasiva arter; Maritim miljö; Fartyg; Påväxt;

    Sammanfattning : The aim of this literature study was to investigate the effects of biofouling in the Baltic Sea. This was done to increase environmental awareness and understanding of the importance of a sustainable marine environment. A systematic search in selected databases resulted in the study being based on tio research articles. LÄS MER

  4. 3. Study of stability improvement measures meeting the effects of new use of a secondhand cement carrier vessel

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

    Författare :Jansen Novri; [2022]
    Nyckelord :ship modification; cargo type; stability code; center of gravity; center of buoyancy; fartygsmodifiering; lasttyp; stabilitetskod; tyngdpunkt; flytkraftscentrum;

    Sammanfattning : Secondhand ship is an option to improve marine business competitiveness. It provides a way for ship owners to integrate customer market rapidly without spending many resources on producing new ships. However, secondhand ships that perfectly suit owner's requirements becomes unavoidable challenge. LÄS MER

  5. 4. Sensor system for pressure measuring over a sail : Construction and implementation of a sail pressure measuring system

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Filip Palm; [2022]
    Nyckelord :Oceanbird; Sail pressure; KTH; pressure sensor system; Environment; Oceanbird; tryckmätningssystem; miljö; KTH; tryckmätning segel;

    Sammanfattning : Wallenius Marine, KTH and SSPA are working together on a wind powered car carrier, that will ship cars over the atlatic. KTH has a small scale prototype of this vessel, and uses this prototype to test performance and new sensor systems, that can be used on the full scale vessel. LÄS MER

  7. 5. Stability Analysis of Hydrodynamic Performance Indicator Based on Historic Data Sets

    Master-uppsats, Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

    Författare :Canan Özel Kennedy; [2022]
    Nyckelord :Stability analysis; Anderson-Darling test; Shapiro-Wilk test; curve fitting; Q-Q plot; British Standard BS ISO 19030;

    Sammanfattning : This paper presents a stability analysis of the sensor data which is collected by QTAGG from alarge ocean going ship and using the stability results, introduces some information about howthe measurements that come from the sensors can be improved and how reliable they are. In thetheoretical part, some background information is given mainly based on British Standard(BS)ISO 19030 which was published in November, 2016. LÄS MER
