Exercise of the ESPS (European Submarine Pilot Society) to leave a sunken privat two person submarine (Psub). A trainning course for the crews of Nemo-II, Two2 and the Euronaut submarine to escape from a submarine. Cours was taken on September 2011 in Potsdam near Berlin, Germany. The new build submarine Nemo II was used in unfinished condition (no electronic or electric) for this exercise. Thanks to the Küster Family for all the support from Michael, Ulrich, Georg, Tom, Arne , Alex, Emile and Carsten. We learn a lot on that weekend.
