Tank Plan Dialog - Content Types Tab.
Content types are the actual contents loaded into compartments in a particular loading condition. Each content type requires an ID, a value for Density (units: tonnes/meter cubed or tons/feet cubed) and the Type to be selected. The Type is selected from the drop-down list, from which 4 options are available:
|
Liquid |
Shifting substance which exhibits free surface moment properties. |
|
Solid |
Non-shifting, dry, substance (no FSM). |
|
Grain |
When selected, a Grain Angle (in degrees) must also be entered, which then determines the upright grain heeling moment. As the vessel heels, the grain heeling moment decreases linearly at the rate of 0.5% per degree. Grain angle is greyed out when one of the other types are selected. When the hold is full, the grain heeling moment will be calculated according to the trimmed ends regulations. |
|
Untrimmed |
As for Grain, except that for full holds, the untrimmed grain regulations apply. |
Within this dialog you can also establish the colour code, from within a drop-down list, that is to be used, for each content type identification number, thus to provide visual clarification within Loading Diagrams.
Note:
When using a black and white printer, these colours will be automatically changed
to different hatching styles. This is the reason for the limited range of colours
available.
The permeability of the cargo when the compartment is damaged, is given in the Permeability (%) column. Permeability in this context means the ratio of the floodable volume between the particles, granules or any larger pieces of the cargo, to the gross volume of the bulk cargo, given as a percentage. This applies generally to solid bulk cargo as specified in IACS Unified Requirements for the Strength of Ships section S17.2. A permeability of zero means that no flood water permeates the cargo, when the compartment is damaged. This is the default. Conversely, 100% permeability means that water will flood the compartment as if no cargo were present.
