TÜMMLER on the Elbe river, seen from Bubendey Ufer, Hamburg, 02.11.2011

At the time of the photo she was a laboratory vessel of Niedersächsischer Landesbetrieb für Wasserwirtschaft, Küsten- und Naturschutz (NLWKN). In 2013 she was withdrawn from service due to an engine breakdown and replaced in 2014 by a new "Tümmler" (built in 1980 as a customs vessel).

No further info about the vessel in the photo found and no info if she was scrapped or what happened to her after the engine breakdown...
