The Damage Stability system for the Ship Hull Characteristics Program SHCP consists of two major supervisor programs Subroutine CMPRTMNT - This program supervises the generation of compartment offsets for the compartment bulkheads and all intermediate ship stations that lie within the bounds of the compartment, based on an outline description of each bulkhead. A Compartment Data Table CDT, similar in form to the Ship Data Table SDT, of offsets, sectional areas, centers of area, and breakpoint, is then created and stored on the Ship Data Tape SDTE for later recall by Subroutine DAMAGE. Subroutine DAMAGE - This program supervised the calculation of damage stability characteristics of the ship minus selected flooded compartments for a range of draft, trim, and heel conditions. The sequence of events for each condition of compartments, draft, trim, and heel is as follows 1 The SDT is read from the SDTPE 2 The volumetric properties of the intact ship are calculated 3 For each selected compartment, the associated CDT is read from the SDTPE and the volumetric properties of the compartment are calculated and stored and 4 The net volumetric properties and the righting arm for the ship minus compartments, i.e., the flooded condition, is computed and output for the condition printed out.
