From November 11th to December 16th, 2021, the company La Méridionale took advantage of a regulatory technical stop of the ferry Piana in Santander (Spain) to equip it with dry particulate filters.
The 3 first prototypes of particulate filters were installed in 2019 with Chantiers de l’Atlantique in charge of engineering and integration supervision support, they demonstrated their ability to treat sulfur oxides and particulate matters.
After this conclusive test, the shipowner decided to make the system permanent on all the ship’s engines, with the additional installation of 3 innovative particulate filters.

La Méridionale has renewed its confidence in the Services BU (Business Unit) of Chantiers de l’Atlantique to carry out the general and detailed engineering for the installation of these dry scrubbers and to support their integration on board the Piana at the shipyard Astilleros de Santander, S.A.U. (“ASTANDER”).

This system, based on an existing concept in service ashore, can neutralize acid gases and assure the fixation of ultrafine particulates. To achieve this, bicarbonate is injected into the exhaust gas. It reacts with the sulfur oxides by neutralizing them and ends up in the filters through which the exhaust gas are led to and from which the particulates and heavy metals are captured to nearly 99%.
