Structure Production Preparation

Create and automate steel structure work preparation to optimize manufacturing

The fabrication and assembly of the ship structure is a core undertaking of the shipyard. The process to convert the engineering design of the ship structure into manufacturing plans to support the fabrication and assembly was long considered an “art” that only highly specialized “loftsmen” could successfully undertake. As technology has taken over the design and manufacturing planning of ships, the process of structure work preparation has started to become more and more automated. A key challenge in today’s modern shipbuilding environments is for shipbuilders to leverage existing “lofting” expertise with integrated design and manufacturing solutions to lead to more efficient and effective structure work preparation and production.


Optimized Production For Sea provides tight integration between design and manufacturing information that allows Structure Production Preparation to correctly interpret the design information that defines the stiffeners and to automatically create the markings where these stiffeners will be positioned and welded. Companies can also define rules based on their experience and know-how to guide the placement of required markings, further optimizing manufacturing. Efficient nesting capabilities help utilize, in the best way possible, steel plates thereby reducing waste. 

Key Highlights and Benefits

  • Perform rule-driven generation of structure work preparation based on engineering design
  • Perform rule driven creation of weld planning and the corresponding manufacturing features
  • Create and modify 3D manufacturing for structure plates and profiles
  • Synchronize manufacturing features based on engineering changes
  • Generate and capture profile and plate nesting information
  • Generate workshop documents such as drawings and XML files
