Locopias Damages

Direct Damages calculations

This module calculates whether the relevant mandatory damage cases comply with the stability requirements in damaged condition. This modules calculates the end stage of flooding as well as the intermediate stages of flooding, even when unequal stages of flooding occur.

The effect of free surfaces in tanks is accounted for by calculating the actual shift of centre of gravity of the liquid in the tanks. The use of this “direct-calculation-method” allows for a more accurate calculation of the vessel stability without the need to “overcorrect” the vessels stability with a free-surface moment correction. These large overcorrection’s mainly occur when tank as almost full or almost empty.

LOCOPIAS takes in account the potential outflow of liquid from a damaged tank. This in order to account for the actual effect of a specific damage case. The effects on stability of an empty or full tank being damaged are noticeably different.

LOCOPIAS also allows for assessment of an actual damage case. The Damages-module allows the user to specify which compartments are damaged, after which LOCOPIAS will calculate the actual stability condition of the vessel.
