Our software systems for ship operations seek to give ship owners and operators efficiency benefits through improved performance while also enhancing ship safety. In addition to ensuring that safety regulations are met, they enable ships to operate in ways that are more economical and ecologically beneficial.

The Onboard-NAPA and NAPA Ship Performance Systems (NAPA SPS) product lines are both based on the same core technology as the NAPA ship design system. Thus the Onboard-NAPA loading computer and NAPA SPS software for fuel optimization and follow-up have the same accuracy and reliability as NAPA. Also, Onboard-NAPA and NAPA SPS base all their calculations on the real 3D product model of the ship, just as NAPA does. Furthermore, since the same calculation engine is utilized, the systems also feature the unbeatable calculation speed of NAPA.

Onboard-NAPA was developed to address the various needs for carrying out ship stability related calculations onboard ships. NAPA’s proven stability and calculation subsystems were the foundation on which Onboard-NAPA’s development was based. NAPA SPS, on the other hand, has its roots in the hydrodynamics subsystems of NAPA.

Established in 1995, Napa Ltd’s subsidiary Onboard-Napa Ltd is in charge of development and marketing of the NAPA ship operation software systems.
