Loading Condition Dialog - Options Tab

General options

If the Check stability criteria option is checked, then the righting lever (GZ) curve properties will be checked for compliance with the specified intact and damage stability criteria sets.

The critical vertical centre of gravity positions will be reported, if the Report Critical KGs option is checked.

If the Set TCG = 0 option is checked, then the position of the centre of gravity for the intact condition, will be adjusted so that the vessel is upright, that means, zero heel angle.

If the Force Even Keel option is checked, then the position of the centre of gravity for the intact condition, will be adjusted so that the vessel has zero trim.

The Vessel is Submerged option has been added to enable the loading condition for a submerged submarine to be calculated. When the option is selected, the vessel is assumed to be fully submerged. The weight is checked and a correction added, so that the weight equals the buoyancy and the trim zero in the upright position. The VCG of this additional weight is located at the same height as the weight before the correction. Draft and immersion information is not output, as this is irrelevant. Also no stability criteria are checked, or damaged states calculated. Longitudinal strength and the free surface of internal compartments, are calculated as normal.

If the Loading Diagram option is checked, then a loading diagram based on the Tankplan, showing the compartment contents, will be included in the report. If this is not required, then uncheck the option.

If the Check Visibility option is checked and parameters for determining visibility have been set up in the Visibility Check node, then the loading report will include the calculated blind length for the equilibrium draft, heel and trim, and a comparison with the required value.

If the Use Even Keel Hydros option is checked, then the tabulated even keel hydrostatics, are used in the loading condition report. Note that this does not effect the loading condition calculations.

If the Interpolate criticals option is checked, then the results from the selected Deterministic Stability calculation will be used when checking compliance with the stability regulations.

Longitudinal Strength options

If you select the BM/SF Limits drop-down menu, then he is presented with a list of names of the specific sets of still water Bending Moment and Shear Force ship-length distributions that he will have created earlier, and from which he can select the single appropriate set that is to be associated with the particular deadweight loading condition, for example an in-harbour operations only condition. If he has not created any BM & SF Limits then nothing will appear.

Note:
Different BM/SF Limits sets can be used for Intact and Damaged conditions.

Longitudinal strength will not be calculated, if the Calc. Long. Strength option is not selected. Bending moments and shear forces are output at peak locations, but if the BM/SF output at Frames option is selected, then the output will be for every frame.

If the Output Torsional Moments option is selected, then torsional moments will be included in the output and checked against the given limits.

The longitudinal strength display options allow you to control the curves that are output in the longitudinal strength diagram.

Compartment Names options

you can select from 3 options for displaying compartment names in the condition report:

• Compartment identifier and long title (default),

• Compartment identifier only, or

• Long title only.

Openings and Deck Edge Points options

The state of openings drop down list allows you to select the appropriate opening state for the loading condition - see Other Data.

There are 3 options for reporting openings and deck edge points, as follows:

• Distances to the water surface are reported for all points. If there are many points, this can be a lot of output.

• Just report the point nearest the waterplane, that means, the critical point, as far as immersion is concerned.

• Do not report any immersion particulars.
