Quick Stability Evaluation

Effective use of stability calculation results.

A typical example demonstrating NAPA’s quick design evaluation capability is the handling of flooding openings in damage stability calculations. As the immersion of openings is calculated on the basis of stability results (except in the case of progressive mode calculations, where the openings affect directly the stability results), no recalculation is needed when openings are redefined.

This is illustrated in the following flow chart:

Changing an opening, e.g. in MARPOL calculations immediately updates the output as the hydrostatics of the damage do not change. The only action required is a little scrolling.
