2. GHS System Overview

2.1 System Structure or Organization

GHS system consists of a main program – GHS x.xx (x.xx is the version numbering) Modules within GHS main program – SE: Section Editor

PM: Part Marker • Appendage Maker • Tank Marker • Display Tools

MC: Model Converter Optional modules for GHS – CG: Condition Graphics

LS: Longitudinal Strength LE: Load editor AF: Advanced Features FL: Floodable Lengths TS: Tank Soundings MB: Multi-Body GS: Grain Shift

HM: Hull Maker PI: Programming Interface GHSCOM: GHS Communications

The GHS system is organized by function. There is a main program (GHS), which handles all of the usual stability computations, both intact and damaged. From there it branches out to several modules that perform special functions. Some of these modules are optional, making it possible to acquire only those functions that are necessary. The essential modules that come with the main program are, • SE: Section Editor

This is an interactive graphical editor for modeling, modifying and displays of hull or any other component of the geometrical model.

• PM: Part Maker Part Marker is a module with Appendage Maker, Tanker Maker and Displays Tools. It is an efficient parametric modeler intend for creating hull, tanks, appendages and superstructure.

• MC: Model Converter Converts models from other formats, including SHCP, HEC, DXF, OFE, IDF, PIAS and SEASAFE to GF format, a format allows for GHS application.

The optional modules are, • CG: Condition Graphics - Illustrates the loaded condition of any vessel. • LS: Longitudinal Strength - shear, bending, stress, and deflection. • LE: Load Editor - a timesaver for working out loading conditions. • AF: Advanced Features - compute IMO probabilistic damage (subdivision indices)

and GM against tank loading for submersibles. • FL: Floodable Lengths - mainly for preliminary design (calculate floodable length and

flooded GM. • TS: Tank Soundings – computes and prints tank sounding tables in various special

formats. • MB: Multi-Body - Allows GHS to model the interactions of multiple vessels. • GS: Grain Shift - calculates volumetric heeling moment for grain cargos. • HM: Hull Maker - a parametric hull model generator (presently for barge only). • GHSCOM - allows access to GHS within other applications program, such as C/C++,

Delphi, Visual Basic, Visual Basic for Applications (VBA), etc. • PI: Programming Interface - allows freedom in developing your own extensions to

GHS.

2.2 GHS Approach In Simulating A Particular Ship Loading Condition GHS system comprises two main categories of software tools for simulating a particular ship loading condition: • Model Building Tool – Section Editor (SE)

Part Marker (PM) • Appendage Marker (AM) • Tank Marker (TM) • Display

Hull Marker (HM) Model Converter (MC)

• Model Analysis Tool – Main Program (GHS) : provide hydrostatic and stability

Load Editor (LE) Longitudinal Strength (LS) Floodable Length (LF) Tank Soundings (TS) Advanced Features (AF) Condition Graphics (CG) Grain Shift (GS) Multi-Body (MC) Surface Areas (SA)

2.3 Geometrical Model Data Structure In GHS A GHS geometric model at various stages of completion is term as Geometry File. In GHS, Geometry file name is allow to be up to 8 characters (maximum) in length followed by optional 3 character extension (e.g. testfile.gf1). A Geometry File contains data file of vessel offsets, it may contain only a hull model or a complete model including appendages, tanks and superstructure. Display Print Command to obtain a printout of the sections and offsets. The overall vessel model is structure into 3 levels of model hierarchy namely as Part, Component and Shape. The completed vessel model will consist of one or more parts (e.g. the hull with its buoyant appendages, with tank and superstructure normally designated as separate part). The parts are classified according to their function. The three basic functions are displacement (e.g. hull), containment (e.g. tank) and sail (e.g. superstructure). Each part, in turn, is divided into one or more Components, e.g. Tank.S\Tank.S or Hull\Skeg.P, (part name\component name). The lowest level of the three levels is the Shape level. This is where the actual geometrical definition of the bodies occurs. Each component consists of exactly one shape. The shape consists of the points on the surface of the body being represented. The modeled shape is a series of stations arranged at suitable intervals such that the important features if the real shape is represented. Model Hierarchy Part name (includes side designator) – 12 Characters class (Displacer, Container, Sail) description tanks only: side(-ve Port, -ve Stbd, Center) substance (fluid contents) capacity sounding tube definition

Component Name – 12 Characters side adding vs. deducting effectiveness or permeability factor (negative deducting) translation vector

Shape Name – 8 Characters Shell thickness Section Longitudinal coordinate (L = X) Point

Transverse coordinate (T = Y) Vertical coordinate (V = Z) 2.4 Coordinate System, Unit, Project Directory and Run Files In GHS Coordinate System To locate the points on the vessel model, Cartesian coordinate system is used in GHS for defining the vessel offset data. The origin (x, y, z = L, T, V) at (0, 0, 0) of the hull model is decided by the user at the initial stage when the model is being built. The origin of the vessel can be anywhere along the length of the vessel. To avoid confusion, GHS uses Longitudinal, Transverse and Vertical (L, T, V) for representing the coordinate system. The signs convention is: positive Aft, positive to Starboard and positive vertically upward. However, the program also recognizes letter suffixes in lieu of signs for longitudinal and transverse directions: “f” and “a” for forward and aft; “p” and “s” for starboard and port.

Units By default GHS start with the program in Imperial System, but this can be change with the UNITS command. For example, switch from Feet to Meters, type the command as follows: UNITS M Project System In the 32-bit version of the main GHS program, you can select the current project by clicking the Project menu, clicking same, and either picking an existing project name or typing a new one. Making sure that the working or data directory for the project us what you want it to be. You can check by typing command, DIR .HERE You can also use the project command to go to the data directory that you want to use for your project’s data files. Simply type the path to the directory; for example PROJ C:\GHS\DATA\TEST. A project folder named as TEST will be created in the directory C:\GHS\DATA. Run Files A Run Files is a file of commands written by a text editor (e.g. Notepad). When the Run File is ready, you can let the program take its instructions from the Run File without entering commands from keyboard. Any command you can enter from keyboard in GHS main program can be placed on a Run File. Using Notepad to create Run File, Run File will have to be saved with the following file name, save as type and encoding under the Notepad save dialogue box: File name: test.rf Save as type: all type Encoding: ANSI

Barge Modeling – Using Section Editor

1. Section Editor – Introduction

SE is a Section-oriented Editor for creating and modifying the Part, Component and Shape definitions contained in Geometry Files (.GF format). It is a special design 3-D modeling program designed to work with the General Hydrostatic system (GHS). It is particularly suitable for create hull models from body plan drawings by means of a digitizer. Although you may create and edit tanks and hull appendages with SE, it is better practice to use Part Marker for these tasks. Part Marker offers more powerful modeling and fitting operations and since it operates from a Run File, corrections and modifications are much more efficient. Section Editor – Defaults Unit for length is in feet.

GHS (program system) – Defaults Station Spacing (minimum) = 1/25 length overall. If length overall = 25m, minimum required station interval will be 1m.

3.2 Completed Geometry File of “210 Feet Barge” Through A Run File

4. Evaluating 210 Feet Barge Intact Stability Characteristics Using GHS & LS Through a RUN File

4.1 Evaluating Loading Condition and Criteria The loading conditions and criteria evaluated were as followed: Loading Condition:

a) Lightship Condition b) Loading Condition 1 Crane on Deck-Forward – 325 MT, LCG 50m Forward of aft Transom, TCG = 0.0m, VCG = 9.6m Accom. Container Deck-Aft – 200 MT, LCG 15m Forward of aft Transom, TCG = 0.0m, VCG = 6.0m c) Loading Condition 2 With the same loading condition of condition 1, load tank “VOID5.P” & ‘VOID5.S” 100% and simulate “VOID2.P” & “VOID2.S” damage.

Criteria: IMO A18 RES 749 (4.7 Pontoon)
