NAPA has been approved and it is continuously used by the world's leading classification societies and maritime administrations.

NAPA sets the industry standards

NAPA integrates effectively the design approval with the overall design process. Most classification societies and maritime authorities use NAPA for their plan approval.

Specific tools have been developed together with leading classification societies to further improve the integration and design process. The Statutory Compliance Manager applications developed for LR and ClassNK contain the up-to-date know-how required for checking statutory requirements.

NAPA is one of the main tools used by experts in the development of new stability regulations. The Flooding Simulation feature, for example, for calculating progressive flooding and the floating position of the damaged ship offers a powerful tool especially for future stability regulations.
