Deterministic Stability Objective

The objective of the deterministic stability calculations is to analyse 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, as described in the following sections.

The program will calculate the vessel's intact displacement and other hydrostatic particulars for up to 10 drafts and 5 trims for a given KGf and heel angle.

Damage stability calculations may be performed for any number of damage scenarios. These damage scenarios are created on the Damage Scenarios dialog (refer to Creation of Damage Scenarios for further information).

The intact and damaged results include a summary of the conditions, 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.
