Creation of Loading Condition Data

In order to establish the various deadweight loading components sub-sets that may or may not be used in a particular Loading Condition, you do this by selecting the Loading Condition icon. Noting that a user will probably wish to eventually create and analyze several different deadweight loading conditions, then your first action will probably be to establish the name of the particular loading condition and create the required number of duplicated branches. The name of the node in the application tree will automatically become that of the particular loading condition that you provide. Typically one branch could represent the lightship, other branches would represent each of the various cargo conditions and covering both departure and arrival conditions, branches could represent ballast conditions, both normal and heavy weather, and other conditions frequently contained within Trim and Stability books.

Calc presents you with a dialog box in which he can identify the fixed weights and compartments sub-sets, from the lists of such that are presented, and that collectively constitute the overall deadweight loading condition. If a sub-set is required, but not presented with the list of those that are available, then you can create it using the approaches that are discussed in the following sections and then add it to the list.

Complete loading conditions are assembled on the Loading Condition dialog by selecting the appropriate subsets for each condition. Any number of fixed weight and compartment loading subsets may be combined in the same loading condition, with the one proviso that two or more compartment loading subsets cannot include a weight in the same compartment. To ensure that this rule is upheld, Calc does not allow the selection of the second subset if this is so found. Since fixed weights are not defined in terms of the occupied physical space, there is no similar check made for fixed weight subsets. Since only one container subset can be included in a loading condition, a container subset must be a complete definition of all the containers in the particular condition. The container subset could be, for example, either a fully laden ship set or an on-deck set to be carried in combination with dry bulk cargo in the holds. you should be aware that there are no interference checks made between the three different types of subsets.
