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

    Författare :Hulda Winnes; [2010]
    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

  2. 2. Particle Emissions from Ships

    Författare :Maria Zetterdahl; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LNG; marine fuel; fuel sulphur content; particle emission; sulphur emission control area; aromatics; SECA; heavy fuel oil; marine diesel oil; liquefied natural gas; ship emission;

    Sammanfattning : Since 1st of January 2015 ships operating in sulphur emission control areas (SECAs) have to use marine fuels with a fuel sulphur content less than 0.1 %m/m. This regulation forces the ship owners to make a fuel shift and use low-sulphur marine fuel oils, use alternative fuels or use scrubbers on-board their ships. LÄS MER

  3. 3. Remote Measurements of Gas and Particulate Matter Emissions from Individual Ships

    Författare :Jörg Beecken; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pollution; compliance monitoring; shipping; ship emission; particle emissions; identification of polluting ships; emission factors;

    Sammanfattning : Shipping significantly contributes to the world's anthropogenic emissions of sulfur, nitrogen species and particulate matter. These species affect the global radiative forcing as well as local acidification, eutrophication and human health. LÄS MER

  4. 4. Remote Measurements of Ship Emissions

    Författare :Niklas Berg; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; airborne; Ship emissions; sulphur dioxide; nitrogen dioxide; DOAS; in situ measurements; carbon dioxide;

    Sammanfattning : The combustion of sulphur-containing fossil fuels gives rise to emissions of sulphurdioxide. Nitrogen oxides are also emitted when fuels are burned. The InternationalMaritime Organization (IMO) has ratified regulations regarding Sulphur Fuel Content(SFC) and NOx emissions from the shipping sector. LÄS MER

  5. 5. The Character of the Particle Emissions from Possible Future Marine Fuels in SOx ECAs

    Författare :Maria Anderson; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy fuel oil; emission factor; marine fuel; black carbon; marine diesel oil; LNG; ship emission; liquefied natural gas; nanoparticle;

    Sammanfattning : Particles in the ambient air come from both natural and anthropogenic sources. One anthropogenic source is combustion of fossil fuels. The awareness of these particles impact on human health and climate has increased the interest for the particle emissions from e.g. LÄS MER
