  1. 1. Waste heat recovery in a cruise vessel

    University dissertation from Kalmar : Linnaeus Universtity

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

    Abstract : 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. READ MORE

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

    University dissertation from Växjö : Linnaeus University Press

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

    Abstract : 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. READ MORE

  3. 3. Management of ship-generated waste - illustrated from the Baltic Sea perspective

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Magda Wilewska-Bien; [2017]

    Abstract : Globally around one-third of food produced for human consumption is wasted or lost. Although the food waste issues on land are being widely discussed, the food waste generated on ships seems not to receive similar attention. READ MORE

  4. 4. Controlling the Roll Responses of Volume Carriers

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Carl-Johan Söder; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PCTC; parametric roll; roll response; roll damping; rudder control; aerodynamic roll damping; roll mitigation; racking; Ikeda’s method; CFD; model tests; Full-scale tests; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : Modern volume carriers such as container vessels, cruise ships and Pure Car and Truck Carriers (PCTC’s) have become more vulnerable to critical roll responses as built in margins have been traded against increased transport efficiency. The research presented in this doctoral thesis aims at enhancing the predictability and control of these critical roll responses. READ MORE

  5. 5. Quantification of sources and removal mechanisms of atmospheric aerosol particles

    University dissertation from Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Author : Henrik Grythe; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aerosol; aerosol removal; aerosol emission; aerosol sources; FLEXPART; Arctic aerosol; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The focus of this work has been to quantify important processes for climatically relevant aerosols, and to improve our understanding of, and ability to accurately model, aerosols in the atmosphere on a large scale. This thesis contains five papers focused on different parts of the life cycle of atmospheric aerosol particles. READ MORE
