Specified Condition analysis lets you determine the hydrostatic parameters of the vessel by specifying the heel, trim and immersion. Heel can be specified by either the angle of heel or the TCG and VCG. Trim can be specified by the actual trim measurement, or the LCG and VCG. Immersion can be specified by either the displacement or the draft.
Select Specified Conditions from the Analysis Type option in the Analysis menu or toolbar.
The settings required for Specified Condition analysis are:
§ Specified Conditions from the Analysis menu
Three Sets of variables are provided, labelled Heel, Trim and Immersion. One choice must be made from each of these groups. Hydromax will then solve for the vessel hydrostatics at the conditions specified.
Values from the current loading condition can be inserted into the Centre of Gravity and Displacement fields by clicking on the Get Loadcase Values button.
Also see:
Setting the Frame of Reference on page 20
Specified Conditions on page 97 in the Analysis Settings section.
Note:
If the fluid simulation has been turned on in a previous analysis mode, then the VCG obtained from the loadcase will not include the free surface correction; the “Get Loadcase Values” button will return exactly the displacement and CG as displayed in the current loadcase window.
The specified condition analysis itself ignores tank fillings and does no correction to VCG.
The following environments can be applied to the Specified Condition analysis:
§ Density
§ Wave Form (if any)
§ Hog and Sag (if any)
§ Damage (or Intact) from the Analysis toolbar
The specified conditions results are the same as equilibrium analysis results except that criteria are not evaluated, i.e. hydrostatic data and key points freeboard are calculated.
