GHS/BHS Bug Report

Versions affected:

8.76C - 10.46

Note that this bug has been fixed in versions 10.46A and subsequent versions.

Program area affected:

Spilling Tanks

Conditions under which a problem could occur:

The FSM values of tanks in spilling mode were being reported for the surface at the nominal load setting rather than for the surface at the spill point.

Discussion:

This bug affects only the free surface moment, not the actual free surface. Therefore the volume properties of the tank are correct, and righting-arm calculations are correct (unless RA /FSM is being used, which would not make sense with spilling tanks present).

Workaround:

Before getting a report where the free surface is shown, the load level in a spilling condition can be captured, then the tank converted to intact:

LOAD *
TYPE INTACT

It should then be reestablished to spill.

LOAD 1
TYPE SPILL
