The "WN" series built on the hull lines and the basic design of the Wartenfels class , but only had aft bridge structures. Despite this basis, which was constructed at the end of the 1950s, the DDG "Hansa " implemented a number of innovations with the ship type "WN". On the one hand, the heavy lift ships were designed as fast freighters in order to counteract the loss of time due to waiting times in the ports of their trade area, which were chronically congested at the time. In addition, the Crostafels ships were the first of the shipping company to allow a real 16-hour watch-free machine operation through a complex monitoring system. The loading gear consisted of a swinging 150-ton telescopic boom, eight 5/10-ton loading beams, two 5-ton loading beams and two mobile 5-ton cranes. The construction of the main deck had been reinforced for a higher deck load and the wooden hatch covers of the earlier series were replaced by MacGregor single-pull hatch covers in the "WN" type.

The keel laid for the first ship of the newly developed series took place on June 7, 1966. After the launch of construction no. In 1360 at AG "Weser", the finished crostafels were delivered to the shipping company on December 28, 1966. Exactly nine months later, on September 28, 1967, the shipping company was able to take over the last ship of the sextet, the Kybfels .
