Airborne monitoring of compliance to NOx emission regulations from ocean-going vessels in the Belgian North Sea

Along the worldwide tightening of standards for sulphur emission from ocean going vessels (OGVs) come actions that are also being taken to reduce nitrogen emission. Particularly, as a milestone in this regard, on January 1st , 2021 NO x Emission Control Area (NECA) North Sea and Baltic came into effect. In response newly established NECA, sniffer sensor system Belgian coastguard aircraft was modified extended with sensor. Moreover, methodology developed evaluate OGV compliance limits through situ measurements plume exhaust. The quality uncertainty demonstrate it is likely achieve an effective monitoring sea. Those further divided four tiers depending keel laying date. As has been proved by results, emissions Tier II OGVs, contrary what might be expected, average higher than those I OGVs. What even more problematic, OGVs have often found non-compliant • Airborne MARPOL Annex VI regulation 13. Quality airborne measurements. may NOx vessels.
