NAPA Steel

Utilized by leading shipyards and design consultancies, NAPA Steel offers a new level of speed and flexibility for structural design. Further, NAPA Steel serves as a database for numerous design levels and is seamless in integration with production and outfitting systems

NAPA Steel is an integrated tool for various structural design tasks



Intelligent system for structural design

  • Increased productivity by using an integrated 3D model from the beginning of the design process
  • Consistent database for multiple design aspects as compartments are part of the same model
  • Enhanced accuracy of calculation results by using a 3D model
  • Significant time savings in creating finite element mesh from the structure model
  • Fast and consistent scantling analysis with the most common class rule check software
  • Rapid and flexible model variations provide possibilities for optimization and studying multiple design alternatives in shorter time
  • Automatic generation of drawings from the NAPA Steel model prevent typical inconsistencies between drawings while the model is frequently changing
  • Integration with outfitting design systems enable starting 3D outfitting design months earlier in the design process with higher quality information
  • Export to production design systems enables smooth transition and increased efficiency

NAPA Steel key features

  • Numeric outputs: Weight and center of gravity, bill of materials, welding lengths and painting areas
  • Generating data for production planning and cost estimation
  • Section modulus and radius of gyration
  • Generation of drawings and visualizations for plan approval
  • Data exchange with classification societies’ systems for scantling analysis and FEM
  • Export of the 3D structural model to outfitting and production design systems
  • Automatic idealization and generation of FEM mesh, export to FEM solvers such as Nastran and Ansys
  • IGES and DXF interfaces for linking to a wide variety of general CAD systems such as AutoCAD

For ship designers

Efficient design tool enabling rapid design variations. Automated generation of drawings provides time savings and is less prone to errors

For shipyards

Integrated design system covering all structural design aspects and relevant interfaces enables consistent designs. Accurate production planning already in early design stages provides savings

For offshore designers

3D structural design from the first steps of the project for even the most complicated geometries

For naval designers

Flexible concept design model for optimization. Automatic generation of numerous FEM models with local refinements. Interface to survivability assessment
