In 2020 the Development and Assessment Institute in Waste Water Technology at RWTH Aachen University (PIA) in cooperation with the Ship Safety Division (BG for Transport and Traffic) and the German Shipowners' Association (VDR) invites to SOWOS 12, a symposium on environmental topics and prevention of pollution from ships.

The seas are the largest ecological system of the earth. And yet, seagoing vessels are typically used in long-distance traffic and are not limited regionally. Thus, all involved parties need to set common goals and cooperate internationally in order to protect the seas. Only in this way can solutions be found. In previous symposiums about sewage, bilge and ballast water and flue gas cleaning, the participants became aware of the need for substantial discussion on all of these topics. Due to this demand, PIA and its partners decided that a 12th Symposium should be arranged.

SOWOS 12 will be held as a 2-days conference on 28-29 May 2020. On day 1 the conference is guest on the cruise vessel "Mein Schiff 4" of TUI Cruises.

SOWOS is a conference for all the parties involved (authorities, certifying bodies, constructors, operators, shipowners, ship yards, etc.). SOWOS enables discussions between all participants in an informal meeting.
