1. Remote Measurements of Ship Emissions
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
2. Particle Emissions from Ships
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. Reducing ships' fuel consumption and emissions by learning from data
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
4. Remote Measurements of Gas and Particulate Matter Emissions from Individual Ships
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
5. A Generic Model for Simulation of the Energy Performance of Ships - from Early Design to Operational Conditions
Sammanfattning : Forecasts show a doubling of the world’s transportation needs until 2050. Shipping today accounts for 90% of all freight transport. Simultaneously, shipping must become cleaner and more energy-efficient to meet the target to more than halve 2005 greenhouse gas emissions by 2050. LÄS MER
