The Johann Welker ship is one of five after the Second World War as a self-drive developed types of ships of the German inland navigation.

details

In the time after the Second World War, a large part of the units destroyed or damaged in the war had to be replaced in German inland navigation. To this end the Technical Committee took Central Association of German inland waterways his interrupted during the war back to work and developed in collaboration with the Federal Ministry of Transport different to certain channel dimensions adapted standard ship types . For the journey on the Rhine-Herne Canal , the Rhine-Herne Canal was 85 meters long, 9.5 meters wide and 2.5 meters deep. The ships were later extended up to 110 meters. The self-propelled committee (a subcommittee of the technical committee), under the leadership of chairman Ernst Weber, continued the interrupted pre-war work on the further development of the Rhine-Herne canal ship . With the cooperation of the shipyard owner Theodor Hitzler, whose concern was the typification of inland vessels, the engineer Friedrich Kölln, who took over the construction, and the engineer Helm from the Hamburg Shipbuilding Research Institute , who led the towing tests, the self-propelled committee developed the Johann Welker ship . The transition from rivet construction to welding resulted in a weight saving of eight percent in the construction of the hull. The ships have a cargo space of around 1900 m³ and a load capacity of around 1240 to 1350 tons. There were versions with one and two propellers - the propulsion power was around 700 hp with one engine and around 1000 hp with two-engine ships. After completion of the development, the members were provided with building descriptions and line plans in order to be able to implement the construction of the ship type as uniformly as possible. At the end of the 1960s, the Johann Welker ship was developed into the European ship , which has the same basic dimensions.
