Deterministic Stability

In order to calculate a Deterministic Stability run, you can edit the 'Stability - Deterministic Stability' node and ensure that all input data is complete and current.

The objective of the deterministic stability calculation is to analyze the stability characteristics of the vessel based on the initial draft, trim, KGf and heel angle, considering both intact and damaged conditions. This information can then be used to calculate the critical KG or GM values, or permissible grain heeling moments.

The program will calculate the vessel's intact displacement and other hydrostatic particulars for up to 40 drafts and 5 trims for a given KGf and heel.

Damage stability calculations may be performed for any number of damage scenarios (see link to damage scenarios below).

The intact and damaged results can include a summary of the condition, hydrostatics at equilibrium, the GZ curve in tabular format and a list of the all openings and deck edge points giving their angle of immersion and distance to the waterline at equilibrium. In both cases the vessel will be balanced assuming that it is free to trim and heel.
