Project presentation

This project aims to increase our knowledge of the nature and concentration of fine particles emitted by maritime transport, in particular by accurately quantifying fine particle emissions linked to port manoeuvres, using dynamic source (stack) acquisitions synchronised with the recording of ship parameters (position, speed, load) and propulsion. – To define a validated experimental methodology for measuring particle emissions under operating conditions,


– Carry out dynamic measurements of fine particle emissions

– Correlate stack emissions with air quality measurements in the immediate environment (deck and cabin measurements) and in the port environment,

– Test the improvements in fine particle emissions obtained using two technological solutions

– Carry out two test campaigns on the ‘Honfleur’, a Brittany Ferries vessel equipped with an LNG propulsion system, whose real emissions can be assessed under operating conditions using iso instrumentation, and characterise the nature of the fine particles emitted.

Project duration : September 2019 to September 2022
