The German-based Shipyard J.J. Sietas, used Nupas-Cadmatic for its intricate offshore wind farm transport and installation vessel. The jack-up was developed for use near the coast in offshore wind parks. The vessel required a complex design in order to operate reliably, quickly and hold a stable position, even in heavy seas. JJ Sietas required software that could efficiently cope with these characteristics. With the use of Nupas-Cadmatic J.J. Sietas managed to reduce the design and engineering time to a minimum.
