HYDROSTATICS : Calculates sections properties (Bonjean) and conventional hydrostatics at specified waterlines, trims and heel angles. Hull deflection may be accounted for by using a parabolic waterline.

TRIM LINES : Calculates final damaged ship conditions after shell-to-shell compartments are flooded.

LONGITUDINAL STRENGTH : Performs calculations of load, shear force, deflection, bending moment and stresses along ship's length, in still water and on trochoidal waves.

FLOODABLE LENGTHS : Calculates floodable lengths corresponding to user defined margin line and set of permeabilities.

LIMITING DRAFTS : Determine the maximum allowable drafts, fore and aft, before damage.

INTACT STABILITY : Calculates either statical stability curves (free to trim) or cross curves (fixed trim) at the user specified heel angles, VCGs, displacements or drafts and LCGs or trims.

DAMAGE STABILITY CROSS CURVES : Calculates cross curves of stability in damaged condition for each combination of draft, trim and heel angle. Compartments are defined by intersection of fore and aft bulkheads, inner and outer longitudinal bulkheads, lower and upper horizontal boundaries, using either hull or compartments offsets. Up to 60 compartments may be combined in one damaged condition.

DAMAGE STATICAL STABILITY : Calculates righting arms, draft and trim in damaged conditions at user specified displacement, LCG, VCG and heel angles. Righting arm curves will be calculated at specified Flooding Stages.

INTACT STABILITY ON WAVES : Calculates righting arms, draft and trim for a ship balanced on trochoidal waves.

TRIM and STABILITY : Produces a trim and stability condition sheet for each user defined loading condition. Loads are selected from a pre-defined library. The following results are printed viz : hydrostatics properties, trim and stability data, righting arm (RA) and righting energy (RE) values for each specified heel angle, maximum RA and corresponding RE and heel angle, angle of immersion of critical and/or flooding points with corresponding RA and RE, residual freeboard at critical and/or flooding points, required versus attained criteria values, graph of RA versus heel angles showing immersion angle of critical and/or downfllooding points together with GM and operational draft.

TANK CALIBRATION : Produces tank calibration tables and curves for each tank described. Tanks are formed by combining compartments defined in the same way used in damaged stability calculations. Curved sounding pipes can easily be defined by the user.

PROBABILISTIC DAMAGE STABILITY : PC-SHCP supports the probabilistic damage stability calculations according to IMO Resolution A.265(VIII), IMO MSC Circular 574 and IMO Resolution MSC.19(58).

MAXIMUM VCG : This module computes and plots maximum VCG curves versus displacement in intact or damaged conditions, for a specified set of criteria. The program will compute a maximum VCG curve for each of the specified Displacement/Draft at each specified LCG/Trim and for each damage case.

STABILITY CRITERIA : Stability criteria may be used to monitor a pass or fail condition in intact or damage stability calculations, or to compute a maximum VCG value. Criteria sets are saved in disk files separated from the hull offsets files, so that once defined they may be used with any offsets file. A set of stability criteria consists of a criteria title and of up to ten (10) criteria. A flexible syntax has been adopted for criteria definition. This method allows you to define new sets of criteria for almost any existing or future international or national authorities regulations.

HULL DEFINITION

The method of hull definition allows for direct modeling of ships with tunnels sterns, multihulls, swath vessels, and virtually any type of modern hull forms, with a minimum number of offsets and stations.

The hull shape is defined by a series of stations along the length of the hull. The station offsets consists of a series of points half-breadth and height above baseline. The stations and points need not be evenly spaced. Hard chines (knuckles) may be defined by entering breakpoints. When calculating section properties, the program fits a second order parabola through three (3) consecutives points. Straight lines segments are used between two breakpoints.

In addition to main hull, compartments and appendages may be defined by separate offsets tables. Appendages volume may be added or deducted from the hull volume. Appendages may also be added by specifying their volume, VCB, LCB and TCB.

Offsets entry may be peformed through a keyboard or a digitizing tablet. Either method is available at any time. You may digitize a station then modify the offsets by switching to the offsets window. When you enter the offsets using a keyboard you may draw the stations at any time to see how the program fits them.

Two types of stations are handled by PC-SHCP, viz 'OPEN' and 'CLOSED'. In OPEN stations the first and last points must lie on the centerline. The CLOSED stations must form a closed-loop. The coordinates of the last point are always equal to those of the first point of the station.

PC-SHCP REPORT

PC-SHCP Report is used for viewing and printing the output files and the graphics created by the  calculation module.

PC-SHCP Report is a Multiple Document Interface (MDI) application, which means that more than one document can be open at the same time.

You may open Output files with the menu command or by clicking on the corresponding button. After selecting the Output file in the File Open dialog box, a new Output window will be created to display the file.

You may preview Output files simply by clicking on the Print Preview button. This action will open a window where the active output file will be displayed in WYSIWYG mode. If the Include Graph option was checked in the Preferences dialog box, the corresponding graphics will be included in the output.

In the Preview window, you may display the first page, the previous page, the next page or the last page. You may also open the Page Setup dialog box, open the Print dialog box or select the zoom scale with the Zoom combo box.

Page settings (headers, footers, fonts, margins...) may be modified before printing the report by selecting the menu command or by clicking on the corresponding button to open the Page Setup dialog box.

Clicking on the Print button will open the Print dialog box. Choose OK to print the whole report or only the selected pages and/or graphs.
