  1. 1. Reducing ships' fuel consumption and emissions by learning from data

    Detta är en avhandling från Växjö : Linnaeus University Press

    Författare :Fredrik Ahlgren; Linnéuniversitetet.; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shipping; energy efficiency; orc; machine learning; emissions; Sjöfartsvetenskap; Maritime Science;

    Sammanfattning : In the context of reducing both greenhouse gases and hazardous emissions, the shipping sector faces a major challenge as it is currently responsible for 11% of the transport sector’s anthropogenic greenhouse gas emissions. Even as emissions reductions are needed, the demand for the transport sector rises exponentially every year. LÄS MER

  2. 2. Waste heat recovery in a cruise vessel

    Detta är en avhandling från Kalmar : Linnaeus Universtity

    Författare :Fredrik Ahlgren; Linnéuniversitetet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; whr; orc; ships; waste heat recovery; energy efficiency; cruise ships; Sjöfartsvetenskap; Maritime Science;

    Sammanfattning : In three studies of a cruise ship the author has investigated waste heat recovery (WHR)from exhaust gases using an organic Rankine cycle (ORC), and also mapped the energyand exergy flows within the ship. Data were collected from the ship’s machinerysystem for a total extent of one year, and this data were used for simulations andenergy calculations. LÄS MER

  3. 3. Complexity and Ambivalence in Ship Safety Inspection The view of Swedish Port state control officers

    Detta är en avhandling från Växjö : Linnaeus University Press

    Författare :Fredrik Hjorth; Linnéuniversitetet.; [2015]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Inspection; Port state control; Detention; Deprofessionalization; Compliance; Maritime safety; Profession; Bureaucracy; Sjöfartsvetenskap; Maritime Science;

    Sammanfattning : Despite an extensive system of Port state controls (PSC) on ships, inspection loopholes in European control functions have been reported. Furthermore, risk factors associated with fatigue, stress and a poorly developed safety culture on board ships have been identified in earlier research. LÄS MER

  4. 4. Heat Transfer Prediction of In Service Welding in a Forced Flow of Fluid

    Detta är en avhandling från Gothenburg : Chalmers Univeristy of Technology, Department of Shipping and Marine Technology

    Författare :Per Lindström; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sjöfartsvetenskap; Maritime Science;

    Sammanfattning : An algorithm for heat transfer prediction of in-service welding operations in a forcedflow of fluid is presented. The algorithm presented is derived from Rosenthal’s 3D heatflow equation and boundary layer approximations. LÄS MER
