A lock gate can be seen on the left and behind the submarine is another and the lock behind is higher than the shown lock which means the submarine is descending to sea level. She may be in a center lock or the last lock. It is unclear which direction she is proceeding.
The time frame is most likely prior to her March 1924 to February 1925 conversion, when she became an engineering test platform, testing a variety of engine configurations. Her standard S-class bow was replaced with a radical new bow to test the sea keeping and submerged abilities of the new design. This type bow was to be used in the next class of submarines, the V-class and in a modified version was used in the later WWII boats and became known as a "fleet bow".
