C2 onboard measurement campaign

On 31 August, SCIPPER researchers boarded “Stena Germanica” vessel of Stenaline for the measurement campaign that investigates the impact of abatement measures on air pollutants emissions. The campaign combines (i) detailed investigation of ship stack emissions, (ii) field test and verification of emission sensors, (iii) test and validation of remote emission monitoring from permanently operated and mobile shore sniffer stations as well as from UAVs.

Two mobile laboratories (one of Tampere University and one of Aix-Marseille Université), carrying advanced state-of-the-art instrumentation for online analyses of detailed chemical composition and physical properties of gases and particles in the exhaust, as well as the monitoring equipment of the Finnish Meteorological Institute and the IVL Swedish Environmental Research Institute are employed for in-stack investigation of emissions.

In parallel, researchers from TNO Netherlands Research Institute for Applied Scientific Research and Aeromon installed emission sensors of gaseous pollutants and particles and established transmission of data to SCIPPER data centre. A prototype of soot sensor developed by Aristotle University Thessaloniki and Helmholtz Centrum Munchen was also employed in the campaign.

A third mobile laboratory of Chalmers University joined the campaign to analyse the plume released from vessel’s stack as well as from bypassing ships with remote technique (IR camera) and sniffer instruments connected to an air inlet placed on a 10-m tall mast. Researchers from Fraunhofer Center for Maritime Technologies and Services joined the remote sensing group with sensors monitoring air pollutants upwind and downwind the stack.

At the same time, the mobile measurement stations of Chalmers University and German Maritime and Hydrographic Agency joined Explicit’s UAV equipped with emission sensors, are monitoring emissions from ships at the entrance to the Kiel canal where the vessel passes on its voyage between Gothenburg and Kiel. During its voyage, the vessel passes also by permanent monitoring stations on Great Belt Bridge and Älvsborg’s fortress (entrance to Gothenburg), both operated by Chalmers University, which also monitors emissions with a second UAV.

This campaign offers unique opportunity for analysis of emissions from current marine fuels and how they are affected by abatement measures and in parallel test sensors and remote techniques for monitoring compliance with current and upcoming maritime environmental legislation. This setup enables valuable cross validation of different sensors and the advanced research instrumentation. This campaign is coordinated by IVL Swedish Environmental Research Institute.
