Hansa building program
The Hansa construction program was a series construction program of standard cargo ship types launched during the Second World War , which was carried out at German and several other shipyards in European countries that Germany occupied during the war in order to compensate for ship losses by German shipping companies due to the war.
history
On June 23, 1942, the eight Bremen and Hamburg shipping companies Bock, Godeffroy & Co., DDG "Hansa" , Deutsche Afrika Linien, John T. Essberger , Hamburg America Line , Hamburg Süd , Norddeutscher Lloyd , Schulte & Bruns and Rob. M. Sloman founded the Schiffahrt Treuhand GmbH with the aim of developing the contractual and financial framework for the program. For this purpose, the necessary materials, such as 420,000 tons of steel, had to be ordered, or questions from the building supervision had to be clarified.
Three types of ships (Hansa Type A, Hansa Type B, Hansa Type C) were built in the Hansa program, which were mainly designed for the accessible navigation areas of the North and Baltic Seas. For each type, a so-called “front-end shipyard” was determined, according to the design of which the series structures were to be built. These were the Deutsche Werft , Hamburg for the smallest type and the Bremer Vulkan for the medium type. The large type was developed by the Deutsche Werft, but built by F. Schichau in Danzig as a front-end shipyard. A total of 65 general cargo ships were built between 1942 and 1945, which were built from Thomasstahl , which was actually too brittle for shipbuilding, due to the scarcity of raw materials and, for the same reason, were equipped with coal-fired steam boilers and piston steam engines , which were already unusual in German shipbuilding at the time. Despite this shortcoming, some of the units, converted to oil-fired boilers, were in service until the late 1970s.
