NAPA Statutory Compliance

Shipyards and marine engineers of today are in need of precise calculation for stability and strength. Through its strong product model, speed, and accurate calculation engine, NAPA’s Statutory analysis tools is the de facto standard for the shipbuilding industry. NAPA offers a comprehensive stability criteria library covering a substantial portion of the existing statutory requirements. In addition, criteria can be defined for any existing and future stability regulations.

NAPA enables rapid and timely damage analysis with an excellent visualisation of results

Stability analysis software for compliance and approval of design and statutory requirements

  • Evaluation capability for all relevant stability criteria and requirements
  • Approved and continuously used by world's leading classification societies and maritime administrations
  • Industry standard module integrating the current regulations and significantly contributes to a smoother approval process
  • Easy-to-use tools for handling the analysis process, such as probabilistic damage stability
  • Flooding simulation enabling time-domain progressive calculations for future stability regulations
  • Superb capabilities for integration into the  ship design process
  • Powerful tools for generating data and reports for relevant parties in the design process
