Performance Prediction Software From Napa Oy

Onboard-NAPA is a program devised by Napa Oy for car ferries, cruise liners, tankers, and naval ships, which enables on-board calculations of ship loading, damage stability analysis and ship performance predictions.

In NAPA — also developed by Napa Oy—all calculations are based directly on a 3D geometry model, affording greater accuracy and reliability. Graphics and data management are based on a unique ship model concept, which enhances accuracy and consistency in both t he calculations and user information. The data are stored in one uniform database for flexible management of loading cases and providing impressive output report with powerful statistics. That accuracy and reliability are also features of Onboard-NAPA, as both systems use the same data and procedures. The design database used for production at a shipyard is directly transferable to Onboard-NAPA, which is available for 486 PCs running the Solaris- UNIX operating system.

According to Napa Oy, t he program improves safety by verifying loading conditions against rules and regulations before departure. It can also be used as an accurate damage stability analyzer for training purposes and in case of an emergency.

The program reportedly promotes maximum utilization of t he ship's cargo carrying capacity by means of accurate cargo planning and the production of precise cargo reports.
