NAPA Damage Stability Calculations Training

This three-day course covers all that you need to get started with damage stability calculations in NAPA.

The basic skills to use NAPA are required.


To begin with, the deterministic method is examined in order to familiarize the users with the damage stability concepts in NAPA. This part of the course is useful for those who have not used the Damage Stability subsystem before.

The course continues with the probabilistic method according to SOLAS II-1, including the index calculation, and Regulations 8 and 9. The calculation routine is gone through step by step for both cargo and passenger ships, by using NAPA Manager application for probabilistic damage stability calculations, known as PROB Manager. 

Day 1 Concepts of damage stability calculations in NAPA, deterministic damage stability, progressive flooding, damage stability criteria
Days 2 -3 Probabilistic damage stability calculations acc. SOLAS II-1
