  1. 1. Air Pollution from Ships - Emission Measurements and Impact Assessments

    Författare :Hulda Winnes; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel; air pollution; ships; impact assessment; emission measurement; ship emissions; emission inventory; manoeuvring ships; abatement;

    Sammanfattning : Environmental impact and air pollution from ships have received increasing attention the last decades. Due to combustion characteristics of typical marine engines and a wide spread use of unrefined fuel, the global fleet emits significant amounts of SO2, NOX and particles to air. LÄS MER

  3. 3. Waste heat recovery in a cruise vessel

    Författare :Fredrik Ahlgren; Marcus Thern; Aykut Ölcer; Linnéuniversitetet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  4. 4. The Regulation of Global SOx Emissions from Ships: IMO proceedings 1988-2008

    Författare :Erik Svensson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; SOCIAL SCIENCES; IMO; SOx; global cap; Annex VI; MARPOL; air pollution; ships; sulphur oxides; policy-making; emissions;

    Sammanfattning : MARPOL Annex VI regulates air pollution from international shipping. Emissions of sulphur oxides (SOx) are regulated through a global limit for the sulphur content of bunker fuels (referred to as a global cap) as well as a stricter limit in particularly sensitive areas, referred to as SOx Emission Control Areas (SECAs).

  5. 5. On Board the Global Workplace : Coordination and Uncertainty on Merchant Ships

    Författare :Carl Sandberg; Patrik Aspers; Arni Sverrison; Boris Holzer; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Coordination; merchant ships; global workplace; mixed crews; formal organization; state of dissonance; evaluative principles; social networks; hierarchy of worth; Sociology; sociologi;

    Sammanfattning : The purpose of this thesis is to analyze how work and social life are coordinated on board merchant ships. The merchant ship is a global workplace where people from different nationalities come together to work and live for an extended period of time.The study is based on ethnographic field work on board merchant ships.
