Engineering Shipbuilding Office ( Dutch NV Ingenieurskantoor voor Scheepsbouw , IvS ) is a Dutch shell company founded by the German Reichsmarine after the First World War to create new developments for submarine projects in connection with the prohibitions imposed by the Versailles Peace Treaty . The company has designed several types of submarines for various countries, including projects of submarines of type "Medium" for the USSR and submarines of type II and type VII for Germany . In addition, the company performed work on the order of the Finnish Ministry of Defense: armored carriers of the Väinämöinen type were built according to their project.

The company was a joint venture of the German shipyards AG Vulcan , Germaniawerft from Kiel and AG Weser from Bremen . Design work was carried out on the territory of these companies in Germany .

Submarine Sales
The company was founded by the German Navy as a branch of the German company Deshimag [1] . The head of the design team was a German, a former submariner, captain Blum, the position of technical director was performed by the famous designer Dr. Techel [1] .
The first submarines designed by IvS were intended for Spain , but were subsequently resold to Turkey . Both of these boats were launched in 1927 and were very close to German UBIII-type submarines from World War I. Between 1927 and 1933, 5 submarines designed by IvS were built in Finland . The first of these was the miniature Saukko , intended for service on Lake Ladoga. The second, CV 707, was later renamed Vesikko and was the prototype for the creation of Type II submarines. Then three boats of the Vetehinen type were built, which were, in fact, the forerunners of German type VII boats . The contracts were designed in such a way that IvS personnel participated in the training of crews, as well as were allowed and took part in submarine sea trials . Thanks to this, the Germans, who at that time were strictly forbidden to have their own submarines, acquired the necessary knowledge about how the new types of boats designed by them behave in practice.
Recent Projects
In 1933, Germany founded a school for training submarine crews under the name "Submarine Defense School" ( Dutch. Unterseebootsabwehrschule ). This school was located in the city of Kiel , and its appearance led to the creation of a flotilla of 8 submarines, with a displacement of 500 tons. Subsequently, their number increased to 16.
Later, Germany developed a plan to recreate the existing fleet. According to this plan, the already designed types of submarines, which were to form the basis of the fleet, were called "Experimental motor boats." The Deutsche Werke plant in Kiel was chosen for their construction, and a new submarine base was to be built in Kiel-Dietrichsdorf. According to the plan, the following submarines were to be built and launched:
- 1934 - 2 large, 800-ton and 2 small, 250-ton submarines.
- 1935 - 4 small 250-ton submarines.
- 1936 - 2 large, 800-ton and 6, 250-ton submarines
- 1937 - 2 large, 800-ton and 6, 250-ton submarines
Cruisers
IvS also participated in the design of battle cruisers for the Netherlands . Line cruisers were considered by some to be very important in protecting the Dutch East Indies from possible expansion by Japan , especially because of the lack of such vessels in the Dutch Navy. These projects were largely based on the German battleship Gneisenau and it was assumed that Germany would build gun turrets for these ships, since their construction in the Netherlands was impossible. As a result, political disagreements did not allow to bring these projects to the end and not a single battleship was launched, since on May 10, 1940, Germany invaded the Netherlands .
