Camber and spring is entered into the section definition.</p>
<p> Hull = Sections +- Selected Appe1 +- Selected Appe2<br />
<br />
Here, the hull geometry is described. The hull is divided into any number of “ShipSections“ and number of points per. section. These definition points can be included directly from the keyboard, but the standard is to use a CAD program like AutoCAD. If you use AutoCAD you can input the ship very quick (you can also import a dwg/dxf file directly into HYPET). In addition to the hull (Sections) you can include two types of appendages to achieve a complete hull. Appe1 means boxes, and Appe2 are Volume-Sections (same element used to compose tanks). All this is defined here.<br />
<br />
<br /><strong>VOLUME SECTION GENERATOR(VSG)</strong><br /><em>Following 4 generators can be used:</em><br />
1. Generator: Usual Volume Section(VS)<br />
2. Generator: Create VS using Curved structure<br />
3. Generator: Create VS using 2 planes<br />
4. Generator: Create Multi VS<br />
<br /><strong>About 1. Generator: Usual Volume Section(VS)</strong><br />
Using the new generator for Volume Sections the definition of compartments becomes a real fun game, that allows you to define any possible volume fast and easy. You tell the program that the volume section will go from X1 (or S56+200) from the AP to X2 (or S62) from the AP, and the program automatically generates three sections. One section in front, one in the middle and one aft. Then you give a simple code to generate the volume section. It can for example be a Wing-Tank defined by the following code: WT(),<-90,#,<0. A double bottom tank that runs on both SB & BB, might look like this: TT(),<180,#,<0. A double bottom tank on the SB side can look like this: TT(); TT(),#; #,TT(), etc. Once you understand this simple code, you will be able to input every tank very fast. WT() or TT() that we used above, means X / Y values obtained from a user-defined longitudinal 3D line. X / Y values exist for each of the three sections per Volume section at given longitudinal position. In this way, it is easy to handle for example forward bulkhead, ascending / descending tank top and deck. If you have used the advantage of this option, it enables you to just go in the definition of the 3d-Lines and afterwards to press a single button that updates ALL volume sections. This gives you the possibility to update 100 tanks in one second.<br />
<br /><strong>About 2. Generator: Create VS using Curved structure</strong><br />
Here you can define any ROUND volume/tank. These tanks can be defined in vertical, transversal or longitudinal position. You just give a diameter or describe the contour line for the tank from center bottom to center top. The program will ROTATE this contour line. If you decide to use 6 VS each tank, then the program will cut through the geometry necessary sections to include these 6 VS. Then we will use 13 separate sections through the actual geometry. You can select to use less or more VS, depending of the accuracy you want. But remember about HYPET's main principal: Use as little as possible without killing accuracy!<br />
<br /><strong>About 3. Generator: Create VS using 2 planes</strong><br />
Now you can let the program create VS between the two defined planes. This means two horizontal or two vertical planes. For horizontal plane, one must either specify a height above BASE in meters to the plane, or you can refer to a 3d line and the program itself will calculate height above BASE. For vertical plane, one must either specify a distance from centreline in meters to the plane, or you can refer to a 3d line where the program itself finds distance from centreline.<br />
<br /><strong>About 4. Generator: Create Multi VS</strong><br />
Here the user can create a longitudinal 3d-line and define a CODE for the compartment. The program will create all necessary VS “following“ the 3d-lines. VS will stop&start at each knuckle on line and in addition you can add your own stop&start points.<br />
<br /><strong>Geometry:</strong><br />
When you define the geometry of the vessel, you can study the hullform and defined compartments by clicking on the icons 3D or 2.5D. There you get a good impression of the defined objects. You can choose to view individual items or selected items for sections, appe1, volume sections, tanks, 3D lines, flooding points, damages, etc. or the whole vessel. By changing the values of X / Y / Z in the "free view" you can study the required elements or the whole boat from different view points. This makes it easy to find out if you have made a mistake during input.<br />
<br /><strong>Definition of Grain Compartments or Grain Cargo Holds:</strong><br />
All definitions for cargo holds that should be filled with grain have to be included in the tank definition window. The loading-calculator H600w uses the same geometry as H100w, so that all tanks can be calculated in both H100w and H600w. Changes in geometry and definitions can only be done in H100w. You define which volume sections shall be used for TANKs and what shall be used for GRAIN cargo holds. If a cargo vessel has longitudinal grain-bulkheads that starts a bit up in the hold, this is no problem for HYPET. The program handles longitudinal grain bulkheads at different levels up from bottom. The only manual work to be done is to calculate STANDARD Void for some Ullage values at the top of the tank where the longitudinal stiffeners can reduce the grain heeling moment. You have to take care that only longitudinal elements in the hatch cover are taken into account which have the same height as the hatch cover itself (See Grain Code).<br />
<br /><strong>CALCULATIONS:</strong><br /><em><strong>NEW</strong></em>: Calculation of Hydrostatic and KY-Values are to be carried out for the documentation in the stability documents and are the basis for the calculation of KG limit curves.<br /><em><strong>OLD</strong></em>: Hydrostatics and KY calculations are performed for documentation, but KY calculations still form the basis for the KG-limit curve<br />
In HYPET H100w you can define all possible stability requirements for KG limit curve for both intact and damaged ship. Standard claims for different ship types can be defined by the user or can be accessed directly from a list and imported.</p>
<p> In H100w you can calculate the waterline with SAC curve, calculate the flow of water line by entering a condition, or retrieve the loading conditions data directly from H600w. You can perform special calculations for both intact and damaged condition and take into account wind pressure, speed of the vessel in turning circle, passenger moment due to crowding on one side, etc. We have added special claim sets for requirements of the Norwegian Navy. The program also features a launching calculation, forward or aft, where you can see the boat sliding down the slipway. Of course you can also find tonnage calculations.<br />
<br /><strong>TONNAGE:</strong><br />
The program calculates, and plots report for tonnage acc. to the 1969 Convention.<br /><em>Gross tonnage is defined as follows:</em><br />
Use the hull as defined by the sections.<br />
+ Selected Appe1 (boxes) For example: 1-14, 25-28<br />
+ Selected Appe2 (Vol. Sect.) For example: 1,3,3 M, 4.4 M, 27.27 M, 28.28 M ,29,33-47<br /><em>NET tonnage is defined as follows:</em><br />
Selected Tanks... For example: 1-4, 8<br />
+ Selected Appe1 (boxes) For example: 1-14, 25-28<br />
+ Selected Appe2 (Vol. Sect.) For example: 48.48 M, 49,50,50 M, 51.52</p>
<p> + Other necessary input...<br />
M - Means that the volume of the compartment is reflected (Mirrored)</p>
<p> <strong>PRINTING</strong>:<br />
H100w can produce all output (prints) from the printing area. You can also define room for your own reports created in Word, Excel, etc. You can define the headers (including number of pages for each item) and the table of content will be printed accordingly. The printing area also allows you to import your files into the final pdf. You just have to place your own reports at the right place. This works perfectly. Finally, if you want to import H600w reports, you can get everything together into one file with a proper table of contents including page numbers.</p>
<p> KY- and KG-limit calculations are ALWAYS calculated automatically for both SB and the PS side.<br />
All output is performed by the program.<br />
<br /><strong>At the end let me say this: MUCH MORE CAN BE DONE INSIDE H100w!</strong></p>
