Tank Plan - Compartments

This tab in the dialog box provides you with a full listing of all of the compartments, by their names, as read into Calc via the input geometry file, plus full volumetric properties and details of each. you can browse through this file and select those compartments that are to be included within the Tank Plan diagram.

This tab sheet also defines compartment categories, and structural and damage permeabilities. you allocates a category, structural permeability (Str.Perm) and damage permeability (Dam.Perm) for each compartment. The category is selected from the drop-down list which contains the category names entered by you in the Edit Categories dialog, plus a further option called NULL (no assigned category). Damage permeabilities are entered in percentages and are used when performing loading calculations and deterministic calculations involving damage scenarios.

Note:
Damage permeabilities for probabilistic stability calculations are specified on the Probabilistic Setup dialog. This is because these can depend on the loading drafts used in the probabilistic calculations.

Compartments that form part of the main hull, are indicated by assigning them to a special main hull category. Both buoyant and internal compartments can be part of the main hull, thus enabling you to allow for features, such as, thruster tunnels, when the calculations are being made. you can also, by simply changing the category, run comparative calculations between a 'clean' hull and one that includes, skegs and sponsons, , if such are included in the full hull external surface definition. The Compartment Names group provides options for the compartment capacity report.
