    Abstract

    ln-depth measurements of gaseous and particulate emissions were conducted onboard an ocean vessel by researcheis from VTT Technical Research Centre'of Finland Ltd, Finnish Meteorological Institute and Tampere University of Technology. Altogether more than 20 different instruments were used in these onboard measurements. A variety of instruments, MAAP (Multi-angle absorption photometer), Aethalometer, FSN (Filter smoke number), AVL MSS (Micro Soot Sensor) were used to measure black carbon (BC) concentrations. In addition, in-depth characterization of gaseous emissions as well as particulate emissions (concentration, composition, size distribution) and their properties (e g. volatility, secondary aerosol formation potential) of a ship equipped with a modern after treatment system (catalyst + scrubber) was achieved by using state-of-the-art online measurement devices (e.9. SPAMS, ELPI, SMPS, PSM, CPC, FTIR, Horiba PG-250A, Pegasor PPS -sensor, Nephelometer, Thermodenuder, PAM -chamber) and filter collections (AVL Smart Sampler). Fuels during measurements were HFO (0.7Yo Sulphur) and MGO (.0.1% Sulphur). The aim of this measurement campaign was to 1) evaluate suitability of BC instruments for onboard measurements and 2) to conduct in-depth characterization of gaseous and particulate emissions of a modern low emission ship. A special focus was on BC emissions as the international maritime organisation (lMO) limit is anticipated for BC emitted by ships. Measurements were successful and large amount of data about the ship emissions was collected. The particulate and gaseous emissions of ship were very low, as expected for a modern ship. The goal is to publish results in the scientific journals and as conference publications. ln addition information for authorities and IMO about the suitability of BC measurement methods for onboard BC measurements will be provided.
