  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. Simulation model of a ship’s energy performance and transportation costs

    University dissertation from Växjö : Linnaeus University Press

    Author : Fabian Tillig; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy efficiency; ship design; speed optimization; energy systems model; performance prediction; wind-assisted propulsion.;

    Abstract : Society faces a major challenge to reduce greenhouse gas emissions to limit the effects and propagation of climate change. As the main contributor to global trade, the shipping industry adds significantly to global greenhouse gas emissions and must actively work towards reducing, or eliminating, emissions in a short period.

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

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Magda Wilewska-Bien; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; shipping; fly ash; Baltic Sea; food waste; nutrients; leaching;

    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

  5. 5. 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
