STATEMENT FOR MINIMUM DRAUGHT FORWARD: The scantling is approved for operation at draft forward not less than 8.00 meters for ice class B. If, in the opinion of the master, sea conditions are likely to cause regular slamming, then other appropriate measures such as a change in speed, heading or an increase in the draught forward may also need to be taken.

Installing inLoad

Learn about the basic features of inLoad, how to install the calculator and repair an installation

hastawieit

nk you for purchasing inLoad Calculator! inLoad aims at setting new ndards in loading calculators by combining an easy to use user interface th sophisticated algorithms. inLoad can be used on PC platforms under her Windows® or Linux® operating systems. inLoad provides an

elaborate interface that is intended to be used by experienced as well as novice users. Most tasks can be performed with a variety of actions – from simple mouse clicks to more complex key combinations. The following paragraphs provide technical details on the installation of inLoad and the technology behind it.

Throughout this manual user actions are presented using the actions on the left. Watch for these icons as they provide valuable information for using inLoad.

When an action requires key combinations, the related

keyboard keys are indicated in a drop shadow box.

When a screen button is to be pressed, the button text appears in single outline.

Three dots "designate that the section is applicable to ships carrying cargo in bulk.

inLoad Calculator is designed and developed so as to be compiled and run on Windows® and Unix® platforms equally well. Nevertheless, not all platforms have been tested. Therefore, it is recommended that inLoad is installed and used either with Windows® 98/Me/XP or with SuSE® or RedHat® Linux® on PC Platforms. Either Intel® or AMD® processors can be employed, featuring 32bit or 64bit addressing. Provided that the above mentioned operating systems are installed and executed effectively, there would normally be no further requirements to run inLoad. It is recommended though that in order to ensure a normal operation, an Intel® Pentium® 4 or AMD® Athlon® processor is used, with 512MB of RAM and 20MB of free disk space. It is also recommended to set your monitor to high resolution (1024x768 pixels).

Installation procedure

The inLoad Calculator consists mainly of three files: the inLoad Calculator Executable, the inLoad Ship Database and the User’s Manual Document. These files are transferred to the hard drive through a simplified setup procedure. To install the software, put the provided disk into your CD drive. There is an executable file in the disk. Run this file by double clicking on the filename. A dialogue appears that guides you through the installation. Simply type in or browse to the desired location where the program should be installed and click “Install”.

There are no missing dlls no required registry entries or anything else to obstruct inLoad execution. This is done for efficiency: installation is simplified and in case of system malfunction, restoring a working state of the installation only requires copying the files back to the hard disk. Further, since the software is intended for shipboard use and relates to ship safety, it is considered a key safety feature to be able to run the software even if a computer fails.

" A shortcut of inload is automatically created to the Windows Desktop by the setup procedure. To execute inLoad, double-click this desktop shortcut or seek and execute the “inload.exe” executable on the destination folder you have chosen during setup. Soon the graphical user interface will load and the ship included in the database will appear on the screen.

Restoring an installation

As already mentioned, there is no particular procedure required to install inLoad. Therefore the user can – at any time – restore inLoad to its base state by simply transferring the initial database to the same location in the hard disk. It is outlined though that this way, all saved loading conditions will be lost. Therefore, it is

recommended that if many users have access to the inLoad calculator, only one should have the right to overwrite the ship database. It is the responsibility of the ship’s officers to monitor access to the loading calculator. On the other hand, it is very easy to maintain backups of the database: provided that all required loading conditions have been saved in a database, close the software and copy the database file to a safekeeping location. This way, it is very easy to restore the customized working state instead of the original working state. Another way to backup your work is exporting the loading conditions and saving them in a safe place.

USER’S INTERFACE MANUAL - page 2 of 54


If a message like the one displayed in the image on the left appears, you should replace the ship database from your original

or backup files. Pressing OK results in

inLoad program raising without opening a

database. You can still try to open the database from the File menu. If the problem

persists, then the database is corrupted and unrecoverable. The user should also try to locate the cause of the database corruption, in order to avoid such a situation in the future.

! It is advisable that damaged databases are sent to Inverso support for recovering as much information as possible ([email protected]).

! inLoad automatically saves the current user display preferences at the end of each session and uses them when the program is executed again. These settings can be overwritten by the defaults by running inLoad from the command line with argument “-reset”, that is “inload.exe –reset”. In this way any display problems can be resolved.

Panes

Navigate through the four panes of inLoad

he major part of the main window is divided into four panes. Most of the information visualization and manipulation and data input is performed by the tools provided in these four panes. T

The Tree Pane allocates the top left corner of the main window working area. The Tree Pane is used to select tanks and weights. Also, it is used to issue reports, visually manage loading conditions and view ship’s general data.

Tanks are enumerated under the Tanks tree leaf. All the tanks of the ship are arranged in appropriate groups.

" Left-click on the symbol to expand the tree leaves.

" Left-Click on a tank group to select the respective tanks. For example, clicking the main leaf named “Tanks”, selects all tanks.

The Weights leaf allows the user to define weights that are not included in tanks, such as deck loads for example.

The Reports leaf includes the four report types that can be exported: Full report, Loading Condition report, Stability report and Strength report.

" Left-click on one of the report leaves to view the report in the report tab at the lower right pane.

" Right-click on one of the report leaves to bring up a pop-up menu where you can select to export the report in RTF or HTML format (see Chapter 7 for details).

If the Loading Conditions leaf is expanded, the available loading conditions are shown.

T R E E P A N E

P A N E S

" Left-click on one of the loading conditions to apply the respective loads to the ship.

" Right-click on one of the loading conditions to bring up a pop-up menu. In this menu, you can find all loading condition management functions. Also, you can import and export loading conditions data.

The Ship General Data leaf provides the same functionality as the Ship Data command in THE COMMANDS TOOLBAR section.

The spreadsheet pane includes a spreadsheet that displays tank information and allows the user to change tank loading and load particulars. Each row of the spreadsheet corresponds to a tank of the ship. There are eight columns to the spreadsheet.

S P R E A D S H E E T

P A N E

In the “Name” column, the name of the tank as it appears in the general arrangement and tank capacity drawings and documents of the ship. The name of

the tank is not editable. The “Cargo Type” column defines the cargo type.

" By double-clicking the cargo type, the list of the available cargo types for the particular space appears. The user can select a new cargo type.

The void type corresponds to any spaces that are not used for carrying any consumables or cargo. Such spaces include for example the engine room and cofferdams.

The “Volume” column defines the volume in the user defined volume units (default unit is cubic meters) of the liquid inside the tank.

# By selecting the cell and typing a number, the cell automatically enters the edit mode. The number is accepted by pressing enter.

" By double-clicking the value of the cell, the user can edit the value indicated.

# By pressing the F2 button, the cell can be edited.

! It is important to note that changing one of the values in columns 3-7 updates accordingly the rest of columns 3-7. Also, note that this automatically updates the loading condition and equilibrium of the ship.


P A N E S

The “Weight” column is the product of the volume by the corresponding density for the content of the tank. The weight is defined in the user defined mass units and the value for each tank can be edited.

The “Volume %” column is the percentage of liquid volume to tank capacity. The volume % value for each tank can be edited.

$ The maximum percentage of liquid in a tank should normally not exceed 98%.

The “Density” column defines the density value in the user defined density units (default units is tons/m3) for the liquid in the tank. The density value changes when the value in the “Cargo Type” column changes. The density value is editable.

! Editing the contents of the “Density” column overrides the default value for the particular cargo type.

The “Sounding” column defines the calculated sounding for the tank. The correspondence between the sounding and the volume can be examined in the sounding table. The Sounding column is editable.

The “Flooded” column indicates whether the space is flooded or intact.

" Double-click the cell that corresponds to the tank that should be flooded. Double-click again to return the tank to the intact condition.

The “FSM” column indicates whether free surface moments are to be taken into account or not.

" Double-click the cell that corresponds to the tank that surface moment calculation method is to be set. A list of available options is then shown: you can select from either SMom, which means that moments will be calculated and taken into account, Fixed which indicates that the cargo surface is considered as fixed (no free surface moment) and Max which indicates that the contents of the cargo are considered fixed and GM and GZ are corrected using the Maximum free surface moment of the tank .

"For spaces carrying grain cargo two more options are available, namely Trimmed and Untrimmed . In this case the tank surface is considered fixed and the surface

type affects only the grain stability calculations "

By clicking any of the cells in the spreadsheet, the corresponding tank is highlighted in the bottom-right pane. The contents of the spreadsheet can be copied to Microsoft Excel® as well as other programs that accept tab-separated text, such as Microsoft word®. Also, cells can be copied from Microsoft Excel® and pasted into the spreadsheet.

! It is not recommended to paste data from other programs into the spreadsheet, in order to effectively keep track of the changes. The Copy/Paste proper functionality is for copying data from the spreadsheet to other programs.


P A N E S

" In order to select data from the spreadsheet, the user starts by clicking into the first cell of the selection. Then, either keep the left mouse button down and drag the mouse to the desired destination cell, or hold shift and click the destination cell.

" In order to select all data in the spreadsheet, the user can click on the top-left empty button in the spreadsheet (at the crossing of column and row names). In the same manner, a single column or row can be selected by pressing the respective header cell.

# In order to select all data of the spreadsheet, press Ctrl+A.

inLoad supports the inclusion of custom weights during the preparation of loading conditions. The input of custom weights is performed through the Weights pane which may be invoked by pressing the ‘Weights’ leaf in the Tree Pane.

W E I G H T S

P A N E

The user can create a new or delete an existing weight by pressing the new or delete button placed in the upper right corner of the Weights pane.

The “Name” field defines the name of the weight to be created.

" By double-clicking the value of the cell, the user can edit the value indicated.

# By selecting the cell and start typing, the cell value can be altered.

# By pressing the F2 button, the cell can be edited.

The “x-Aft” and “x-Fore’’ fields define the longitudinal extend of the weight.

! Please note that x-Aft position may not be greater that x-Fore position. If improper values are entered by the user, a warning message is issued and values are suitably changed.

The “Weight” field defines the total weight of the distribution.

The “LCG”, “ZCG” and “TCG’’ fields define the position of the centre of gravity of the weight.

The “W-Aft” and “W-Fore’’ fields show the values of the weight distribution in the x-Aft and x-Fore longitudinal positions respectively.


P A N E S

! Fields “W-Aft” and “W-Fore’’ are locked and may be used for verification purposes only.

The bottom-left pane is the Ship Data pane. There are four forms available each activated by one of the buttons at the bottom of the pane. Each form includes data that are updated according to the loading condition. These data provide valuable information for the ship status at a glance. The information in these forms is not editable. Nevertheless, it can be copied and pasted into other programs.

S H I P D A T A

P A N E

The Ship General Data form, provides general information about the displacement, drafts, trim and heel angles, along with information on the maximum

shear and bending moments. Also, the total cargo is summed as well as the total ballast used. For each value, the units are displayed next to the name of the value. Also, concise draft verification can be provided through the draft calculations at mark positions on the ship.

The Stability Data Table presents intact stability data related to the stability calculations required by IACS regulations. In order to directly demonstrate compliance or not with stability requirements, the STATUS column indicates a PASS or FAIL respectively. When there is a Stability Alarm (Alarms Toolbar, p. 12) the reason that initiated this alarm will be indicated by an error in this pane.

"Information on grain stability is also provided when required. This table shows the equilibrium angle, residual dynamic stability and initial metacentric height in

case of shift of grain. This table is available only for ships carrying cargo in bulk. "

Note that the header of both tables indicates whether the results are based on pre-calculated cross curves or direct calculations. For more information on this subject, please refer to “Methods of calculating ship stability” in p. 51.


P A N E S

The Strength Data Table presents data related to the longitudinal strength of the ship. The position and value of shear force and bending moment extrema are shown along with the maximum shear force and bending moment. The %PERM column indicates the percentage of permissible value in each case, according to IACS requirements. A value that is greater than 100 indicates that there is excessive shear force or bending moment. As in the previous case, when the Strength Alarm (Alarms Toolbar, p. 12) is given, the reason that initiated this alarm will be indicated by a value greater than 100 in this pane.

An additional data table appears for ships carrying cargo in bulk, where applicable. This table includes local strength data for each hold. For each hold it is tested that the weight in single or adjacent holds meets the cargo hold strength requirements.

The Other Data Table indicates whether there is a violation of other requirements, such as maximum zone draught violation, propeller immersion, minimum draught violation or excessive heel. Any of these violations initiate the Others Alarm.

" In order to bring up any of the above mentioned forms, click the respective button at the bottom of the pane.

The Plotting Pane is where a lot of the work with inLoad is done. Here, the user graphically defines tank loading and visualize the effect of loading on the trim and

heel of the ship, bending moment and shear force distribution and GZ-# curve. Also, any other plots appear in this pane. The Plotting Pane features a tab book. There are three permanent tabs to the tab book: the General Arrangement Tab, the Strength Tab and the GZ-Angle Tab. Each tab, when clicked, activates a plot. There are tabs that appear upon request, such as the Hydrostatic Data Graph and Table. There are two kinds of plots that appear: the general arrangement drawing and the different kinds of graphs.

The General Arrangement Tab

The General Arrangement Tab shows five views of the ship. A side view of the ship showing all tanks and spaces lies on top-left. Three top views follow, showing the cargo, ballast and bunker tanks respectively. The transverse section view lies on top-right. Each tank is filled in each corresponding view up to the free surface of the liquid. The colour used corresponds directly to the colour of the liquid, as shown in the Spreadsheet Pane (Spreadsheet pane, pp.15). The green line shown on the side view is the actual ship waterline. It is outlined that when the trim changes, the waterline rotates to the trim angle and transforms to the appropriate draughts. The side view remains horizontal.

" The drawings and graphs can be zoomed and panned. To zoom in and out, use the mouse wheel. To zoom out, roll the mouse wheel towards the monitor. To zoom in, roll the mouse away from the monitor. To pan the drawing, provided that it does not fit in the pane window, right-click in the drawing and – while the right mouse button is pressed – move the mouse. You will notice that the drawing follows the mouse motion.

" You can also use your mouse to zoom in at a particular area. Left-click in the drawing and – while the left mouse button is pressed – move the mouse. While the mouse is dragged, you will notice that a rectangle appears between the first click and the mouse position. This is the zoom window. If you release the left mouse button, the area of the drawing that lies within the zoom window is zoomed.

# In order to fit a plot in the window, press Esc on your keyboard.

! Note that plot functionality is further explained in the Plot Manual (see Appendix C).

Working with the mouse and the General Arrangement Drawing:

The General Arrangement drawing provides a graphical

way to select and load tanks. There is a wide range of tasks that can be performed using the drawing, most of which is performed at a mouse click. To

"&


P A N E S

select a tank simply click on that tank on one of the ship view. Note what happens then:

! The tank border is green highlighted.

! A tool tip that shows tank specific information appears.

! The spreadsheet changes and shows only information related to the selected tank.

! When you move the mouse without clicking, the selected tank boundary turns red.

! If, where you clicked, tank boundaries overlap, then all possible tanks are selected. For example, click on a cargo tank at the side view: any cargo tank behind it will also be selected.

The last remark also shows a way to select multiple tanks. For example, if you want to select centre, port and starboard tanks of a cargo compartment, click that compartment on the side view.

! Another way to select multiple tanks is to hold the Ctrl button pressed while

clicking on the tanks.

! In order to select a cargo group, use the group leaf at the Tree pane, pp.14.

To load a single tank graphically, select that tank and press the right mouse button. A pop-up menu appears. At the menu, the name of the tank appears so as to verify that you are operating on the correct tank. Information about the cargo type, load level and sounding also appear. The bottom part of the dialog is used to load and unload the tank The Volume command activates a dialog where you can select the volume percentage of load in the tank. To select the desired value, either slide the slider or type in a numerical value at the text field provided. Press OK when finished. You will notice that:

! The liquid level in the tank changes in all views.

! The “Volume %” value for this tank (Spreadsheet pane, pp.15) adjusts to the desired value. In order to completely empty the tank down to 0% volume, select the Empty Tank command. To fill up to 100% the tank, use the Fill Tank command.

! To fill the selected tank completely or incrementally, you may also use the Tank load incrementation and transfer toolbar, pp.12.

In order to empty or fill multiple tanks simultaneously, select the tanks and press the right mouse button. A pop-up menu appears that allows you to empty or fill the selected tanks, just as in the case where a single tank is selected.


P A N E S

From the same pop-up menu, you can resolve a multiple selection to a single selection tank. The Select command at the top of the menu activates a list of the selected tanks. From this list, you can pick the single tank that you want to select.

In many cases, it is useful for the master to have a direct input for the air

drafts of the ship in each loading condition. When air draft positions are available, these are shown with a dotted line on the profile view of the general arrangement plot. The draft value is indicated close to the position of measuring the air draft. In order to present air drafts on the general arrangement plot, the locations of interest must be provided a priori.

The Strength Tab

The strength tab presents shear force and bending moment distributions for the whole ship. The horizontal axis corresponds to the ship length which may be measured in meters (feet) or frames (see the Preferences Dialog for details). There are three vertical axes, for moment, shear force and weight distribution values respectively. Along with the two curves, by default, the regulation limits are also shown. These limits are opaque so as not to blend with the two curves. When there is a Strength Alarm (Alarms Toolbar, pp.12) you will notice that one of the curves will cross the regulation limit curves. By default, the bending moment curve and respective limits are shown in blue colour. The shear force curve and respective limits are shown in red colour. The axes that correspond to the curves are also of the same colour. When moving the mouse button over the BM SF graph, a rectangle is dynamically drawn, which contains information on the current ship length position and the respective BM, SF and limits.

The Strength Plot is highly configurable. A detailed description of plot functionality is given in the Plot Manual (see Appendix C).


P A N E S

One of the basic attributes of plots is the capability to show and hide curves. By default, only bending moment and shear force curves are shown. Nevertheless, the user can select to show the weight, buoyancy and load distributions. Also, any of the curves can be hidden. Further, formatting of the curves is also possible.

" Right-click on the plot. From the pop-up menu, select the Graph Properties command.

" In the dialog that appears, double click the eye icon to show or hide the selected curve. The same result can be achieved by right-clicking a data series and selecting “Toggle Curve

Visibility”. All curves that exist in the graph can be shown or hidden with the above procedure at the user descretion.

Local strength plots

In the case of ships for which local strength calculations are applicable, a secondary set of tabs appears when the strength tab is selected. These two tabs discriminate between the longitudinal strength plot (global) and local strength of cargo holds. The local strength set of plots shows the compliance of the weight in a compartment with the local strength data provided

for single compartments and adjacent compartments. The allowable weight graphs (maximum and minimum allowable weight) are presented. The horizontal axis of each chart shows the draft in length units at the longitudinal centre of the hold (or holds) in question. The vertical axis shows the weight of the cargo and double bottom content. The

solid lines show the allowable maximum and required minimum values. The


P A N E S

current pair of draught and weight for the compartment is annotated on the plot with a cross. When the load is in excess of the limits, the background of the plot is shaded in red.

! Different permissible weight limits (e.g. sea going or harbour) may be applicable for a particular vessel. The user can change the permissible weight limits in effect, by initiating the Modify Loading Condition Dialogue and selecting the appropriate limiting set of curves.

" The user can see the tanks contributing to each local strength calculation by selecting the corresponding local strength. These tanks are automatically selected and the tank spreadsheet is updated so as to contain only the selected tanks.

The Stability Tab

The Stability Tab activates the GZ-# plots for the particular loading condition. A

secondary set of tabs appears, including the applicable tabs for the particular ship type and loading condition. The horizontal axis of these plots corresponds to the heel angle and the vertical axis to the righting lever in all cases. Additional information is indicated, relative to the applicable stability criteria.

I N T A C T S T A B I L I T Y

The Intact tab activates the intact stability plot. The righting lever versus angle of heel curve is plotted with a blue line. This curve is either estimated from cross curves tabular data of the ship or calculated directly. For more information on this subject, please refer to “Methods of calculating ship stability” in p. 51. The GM tangent (green line) is also plotted.

The deck immersion angle and the flooding angle are marked on the curve. The opening from which flooding occurs is also indicated.

W E A T H E R C R I T E R I O N

The Wind tab activates the weather criterion plot if applicable. The wind heeling levers lw1 and lw2 are plotted as the steady (dotted) and gust (dashed) wind curves respectively. The two areas (a and b) defined under the circumstances of the weather criterion are annotated with a hatched area under the GZ- plot. #


P A N E S

" G R A I N S T A B I L I T Y C R I T E R I O N

The Grain tab activates the grain stability plot. This plot includes information for

assessing the stability according to the safe carriage of bulk cargo in grain. In the static stability diagram, the net or residual area between the heeling arm curve and the righting arm curve up to the angle of heel of maximum difference between the ordinates of the two curves, or 40° or the angle of flooding, whichever is the least, is marked with a red hatched area. The equilibrium angle taking into account the

shift of grain is marked on the stability curve. "

L I M I T I N G G M C R I T E R I O N

The Limiting GM tab activates the limiting GM criterion plot if applicable. The horizontal axis of this plot indicates the metacentric height and the vertical axis the draught, both in length units. This plot includes the limiting GM curve which indicates the minimum GM to satisfy intact

stability criteria. The current GM is indicated with a cross on the same plot.

Loading conditions

Loading condition management is one of the most powerful features of inLoad

great deal of the work performed using inLoad results is finding those loading conditions that are feasible and acceptable from the classification society, but most important, those that satisfy the operability and safety requirements of the ship.

A The Loading Conditions in inLoad offer a concise and functional way to archive and restore loads, weights and settings applied to the ship. All loading conditions are saved with the ship’s database. Therefore, as soon as the user has developed a suitable collection of loading conditions in the database, it is advisable to store the database in a backup folder for safekeeping.

L O A D I N G

C O N D I T I O N S

The following information is stored with each loading condition:

% The Name of the loading condition % The Type of Cargo for each tank % The Percentage of Cargo in each tank % The Density of Cargo in each tank % Whether the Free Surface Effect is taken into account for each tank % Whether the tank is Flooded % The Damage Permeability if applicable. % The definition of each Distributed Weight % The desired value of the Sea Density % The assigned Draft Zone % The Date that the loading condition was generated / modified % Comments related to the loading condition (such as a description)

The user is required to define this information for each loading condition. inLoad comes with a number of loading conditions already setup into the ship’s database. These loading conditions are those ones that are included in the Loading Manual of the vessel, or those ones indicated by the relative Classification Society. It is advisable that these loading conditions are not altered. The user is provided with the means to generate new loading conditions based on existing ones. This method can be effectively used to test modifications to existing loading conditions.

L O A D I N G C O N D I T I O N S

The available loading conditions can be seen at the relative leaf in the Tree Pane (Tree pane, pp. 14). Left-clicking on a loading condition name, automatically loads the tanks of the ship and induces all distributed loads. The load level in each tank and distributed loads are then visible in the General Arrangement tab.

! The inLoad program is usually shipped with a number of predefined Loading Conditions. For safety reasons, these Loading Conditions are locked, therefore they cannot be altered by the user.

A new loading condition can be created in two modes: either based on an existing loading condition or starting with all tanks empty and no weights except the light ship.

Reports

Learn how to generate reports with inLoad

ne of the most important tasks performed with inLoad is the generation of reports. Reports are exported in RTF or HTML format. The exported RTF files can be viewed, edited or printed by almost any word processor (such as Microsoft Word® or OpenOffice Writer ®). The

HTML reports can be viewed on any computer that has an HTML viewer installed (such as Microsoft ® Internet Explorer, Netscape Navigator ® or Mozilla FireFox®). Therefore, it is very easy to get all information, view it and manipulate it on any computer.

O

! Especially for HTML reports, the user can reuse part or the whole of the report in the following way: Open the html file using an HTML viewer (such as Microsoft ® Internet Explorer, Netscape Navigator ® or Mozilla FireFox®). Select the desired part of the report. Copy the selected data to the clipboard. Paste the copied data to a newly created or existing Microsoft Word or OpenOffice Writer document.

! The user may send the reports directly to the default system printer. This is done in three different ways.

1) From the menu item “Reports” select “Print” and then the desired type of report.

2) Select the desired report by the tree menu and then press the right mouse button. Select “Print Report” from the popup menu.

3) Right click the report icons in the Report Toolbar.

Automated reports generated by inLoad include: A U T O M A T E D

R E P O R T S % Full Report, comprising general data for the ship, tanks loading analysis table, stability assessment, strength assessment and other issues.

% Loading Condition Report, comprising general data for the ship and tank loading analysis table.

% Stability Report, comprising stability assessment data for the active loading condition.

R E P O R T S

% Strength Report, comprising strength assessment data for the active loading condition.

The data provided in the reports, include:

% General Data: including ship name, loading condition name, sea density, draft zone, number of tanks/cargo tanks/ballast tanks/other tanks and total cargo and ballast onboard (tons). An overview of compliance with regulations with regard to strength, stability and other issues is also provided.

% Tank Loading Analysis: provides the general arrangement image, a table including cargo tank weight calculations and ship hydrostatics at the equilibrium water plane.

% Stability Assessment: provides a table with righting lever information and graph, as well as the calculation of stability criteria according to regulations.

% Strength Assessment: provides a strength assessment table and bending moments shear forces graph.

% Other issues: provides information on maximum zone draft, propeller immersion, minimum forward draft and flood angle.

You can generate these reports either from the Reports Command or from the reports toolbar (Report management toolbar, 11). By selecting one of the report options, a dialog appears where the user is requested to provide information regarding the folder where the report should be saved in as well as the name of the report file. The user

should enter a unique file name in the File Name dialog. By pressing the OK button, the report is generated and saved in the specified location. For HTML reports, the report file is then automatically loaded into the default HTML viewer (for example web browser). The report file can be transferred to another location in the same computer, transferred to another disk or e-mailed. Also, RTF reports can be accessed from a word processing program, where the user can format the file further and amend it to an electronic loading manual for example. It is outlined that altering the data included in the report is greatly discouraged. Specifically, the HTML


R E P O R T S

report is separated into text and images. Images are stored in a separate folder. RTF reports are exported in a similar manner. The difference is that they are not opened automatically nor is there a separate folder for the images, as these are embedded in the file.

The data that will be included in a report can be previewed in the preview tab. By left-clicking on a report type in the tree pane, a new tab appears at the plotting pane. In this tab, only the data that will be included in the report is shown. The name of the tab indicates the kind of data that is shown. Note that the data included in

these tables are related to the current loading condition. Changing a loading condition, causes the table’s content to change.

It is often that data and information for a particular loading condition must be transferred between the ship and operators or other services. In such situations, any of the two kinds of report formats can be dispatched electronically, i.e. through electronic (E-mail) services. If only the text is needed, the HTML file alone can be sent, without the images. This makes it easier to transfer information over slow connections, as the HTML text file is very small in size. If a hardcopy is to be printed and dispatched, it is advised that the RTF format is used, as it is inherently more printer-friendly and can be easily attached or included to other documents.

In the case that the receiver has an official copy of the program, the loading condition can be exported in the inLoad loading condition format and sent over the internet (see “Exporting and importing loading condition data, pp.33). This is the safest and fastest method, as this file is fairly compact and compatible with the software. This way, the receiver will be able to examine the loading condition with his own copy of the software.

Loading Example

Putting it all together into a comprehensive example

his Chapter is devoted to creating a new loading condition either from scratch or based on an existing one. Further, modifications are applied so that a target loading condition is reached, with regard to cargo and bunker capacities. Finally, a report is generated for the new loading condition. The

particular example is prepared for an oil carrier, but the same procedures can be applied for any ship.

Oil Tanker loading example

This example considers an oil carrier loaded with almost all tanks full: a payload of 192000 tons is loaded in the ship. Consider a target loading of 116000 tons. This is a hypothetical condition where some of the cargo is to be removed from the holds. The following Table summarizes the content of cargo holds for the initial (192000 tons) and target (116000 tons) loading conditions.

The following image shows the inLoad screen for the initial loading condition:

There are many ways that the cargo percentage in each tank can be defined. We will visit all of them here. The simplest way to define the cargo content is to define it explicitly for each tank. Nevertheless, there is the possibility that the user might want to try different cargo transfer scenarios between tanks. In summary, cargo can either be directly set for a tank or transferred from another tank.

Setting the cargo in a tank

As an example of setting a different value of cargo loading in a tank, let’s modify the content of CT1C from 98% to 0%. This can be done in many ways:

# In the spreadsheet pane, select the row that corresponds to CT1C and change the content of Volume % column from 98% to 0%. To type inside the particular cell, you can start typing, double click the cell to make the cell

editable or press F2 on your keyboard to make the cell editable.

" In the General Arrangement, select CT1C tank and press the right mouse button. From the popup menu, select the Volume " command. A dialog

appears where you can either set the required percentage by sliding the slider at the top, or directly type the value in the provided text box. Either way, you will notice that the changes are applied to the tank content.

" In the General Arrangement, select CT1C tank. From the Loading Toolbar,

press the button.



Transferring cargo from another tank

In many cases, you may want tot try transferring cargo from one tank to another, in order to verify the effect of such a change to the strength and stability of the ship. This is possible by first selecting the source and target tank and then transferring cargo using the Loading Toolbar. To illustrate this, you may transfer the cargo from CT1C to CT2C in the following way:

% Select the source tank, CT1C by left-clicking it in the General Arrangement.

% Select the target tank, CT2C by left-clicking it in the General Arrangement,

while holding the Ctrl key down.

You will note that both tanks are marked with a red outline.

% In order to transfer the cargo

from CT1C to CT2C, press . This action transfers 20468.2 LT from CT1C tank to CT2C tank.

% Note that this cargo weight does not correspond to 98% volume for CT2C, because this tank is larger than CT1C. Therefore, the Volume % for

CT2C is 90%. To reach the desired percentage, press eight times.

Proceeding with the two methods specified in the previous paragraph, cargo hold content can be adjusted so as to reflect the desired loading for 116000

tons Payload Loading Condition. If you operated on the existing 192000 tons Payload Loading Condition, you will note a star next to its name in the tree pane. This star annotation means that the particular loading condition has been changed. In this case, it is desired that the changes are saved in a new loading condition, under a different name.

As soon as you have created a HTML report, a window will appear that shows this report. Verify that the saved data is correct and consistent with the data you entered for the particular loading condition.

Cement carrier

This example considers a cement carrier in the light ship condition. Starting from this condition, the user is required to add distributed weights to the ship in order to emulate the effect of additional weights like stores that are not included in the light ship condition. Further, a new fully loaded and a new half loaded conditions are created based on the initial loading condition.

" Click on the Loading Conditions menu command to bring up the loading

conditions’ menu. Select the New command from the menu.

A dialogue appears where you can insert details of the new base state of the ship. Enter the name of the base loading condition, for example “Base State 1”. You can insert any comments describing the loading condition. Further, select the Light ship condition as the starting point.

" Right click on the newly created loading condition. A menu appears from where a number of commands that can be executed and affect the loading condition are found. Select the Modify command.

In the dialogue that appears, you can modify the basic characteristics of the loading condition. inLoad considers the sea density, draft zone and strength limits as part of the loading condition and these must be set explicitly for each one. In this case, only the draft zone will be changed from “Tropical Fresh Water” to “Summer Draft”.

! Note: these options depend on the ship type and characteristics and may not be available for all ships.

The base state of this example includes a set of distributed loads. Such loads that are not included in the light ship must be added to the loading condition.

" Click on the Weights leaf in the Tree pane (see “Tree pane”, pp. 14). The Spreadsheet pane is replaced by the Weights pane. The user must now add any additional distributed weights included in the loading condition (see Weights Pane, pp.17).

Repeat for all additional weight until you have input all the required weights.



# Press Ctrl+s on your keyboard or right click the loading condition name on

the Tree pane and select Save. This will save your changes to the loading condition.

This loading condition is the base state for the two loading conditions to follow. Note that the loading condition includes information in the sea density to use for the calculations, draft zone, strength limits, as well as additional weights that are included.

In order to use the work you have performed during the previous step, you need to create loading conditions based on the base state loading condition. To do this, you will create a new loading condition that represents the fully loaded departure state. Repeat the procedure to create a new loading condition. Only this time, select “Base State 1” (remember, this is the name of the loading condition created in step 1) in the “Based on existing loading condition” field in the “Create new loading condition” dialogue. Name the new loaded condition “Fully Loaded Departure”.

! Note that this procedure ensures that the “Fully Loaded Departure” has inherited all the characteristics of the “Base State 1” loading condition. This includes the sea density to use for the calculations, draft zone, strength limits, as well as additional weights and tank loads included in the base state.

! Data input in the base state after a new loading condition is created from this base state, will not be inherited by the latter.

In this example, no tank loads are input in the base state. If certain tank loads are expected to remain unchanged, these can be input in a base state. For the purposes of this example, the following changes to the bunker tanks are made:

" Click on the Bunkers leaf in the Tree pane. You will notice that only the bunkers are displayed in the Spreadsheet pane.

Input the following information in the bunkers table. To do this, type in the appropriate table cell the values presented in this table. Note that for each input value, the graphical representation in the General Arrangement tab reflects the change.

Save the new loading condition. “Fully Loaded Departure” now contains all the information of the particular loading condition except tank loading. If this loading condition can now serve for a series of new loading conditions, the user may select to save it as a new base state. For example, a series of departure loading conditions can differ only in the content of the cargo tanks. Therefore all other common elements can be bundled in a base state.

For the purposes of this example, use the following table to input load in the cargo tanks:

Name Fill % Density [MT/m3]

Save the loading condition. “Fully Loaded Departure” now contains all the information needed. The user must verify that the loading condition is acceptable according to the applicable criteria. If the loading condition is not acceptable, one or more of the three alarms will blink. Also, an audible alarm is provided in order to verify that the user is notified. In order to locate the reason of the alarm or alarms, the user must check which criterion or criteria failed. This information is readily available in the Ship data pane (Ship data pane, pp. 18).



In order to form the half loaded departure condition, a new loading condition must be created. The new loading condition differs from the “Full Loaded Departure” only in the cargo in the holds and some ballast added in some of the ballast tanks. Therefore, the new loading condition can be based on either the “Base State 1” or the “Full Loaded Departure” existing loading conditions. In the former case, the bunker data must also be filled in. In the latter case, only hold and ballast data must be filled in. The appropriate data for the hold and ballast fill is presented in the following table:

inLoad Technology

inLoad design and programming is based on the concept of object-orientation. It is written entirely in Standard C++ and has a system independent nature (i.e. it runs on Microsoft Windows © as well as on LINUX and a number of UNIX based operating systems). The inLoad system comprises of:

• A robust non-linear ship equilibrium solver.

• An enhanced, user-friendly interface providing ease of use and advanced operation capabilities to the user. The user interface is based on the FOX toolkit, a cross-platform graphical user interface library (www.fox-toolkit.org).

• A flexible database system for saving and recovering ship information, as well as user related loading conditions, ship configurations and preferences.

• A collection of optimization utilities for performing constrained optimal loading calculations.

inLoad incorporates advanced features and innovative algorithms for the calculation of the ship’s equilibrium. Volume calculations are performed with efficient underlying algorithms. The geometry of each volume of the ship (the tanks and the hull itself) is described using appropriate sets of points. Using various integration techniques in the form of built-in functions, an extended number of volume parameters are calculated at every solution step. Such parameters include volumes, center of volumes, volume moments, buoyancy distribution, weights, weight distributions, centers of gravity, free surface areas, centers of free surfaces and first and second-order moments.

The hull itself is modeled as a volume with the advanced features of buoyancy distribution, metacentric height, etc. Given a loading condition (i.e. the amount of cargo in each tank and the distributed or concentrated loads) an iterative algorithm performs the following steps toward the calculation of the ship’s equilibrium position:

1. The ship is considered to be in a starting condition, namely in the lightship condition.

2. The volumes are set to contain the predefined amount of weight. For the given heel and trim of the ship, the weight characteristics of each volume (i.e.

I N L O A D T E C H N O L O G Y

center of gravity, volume moments, weight distributions, free surface areas, centers of free surfaces and first and second-order moments) are calculated.

3. By summation of the light ship characteristics, the distributed and concentrated weights and the volume characteristics calculated in the previous step, the overall ship weight characteristics (total weight, W and longitudinal and transverse center of gravity, LCG and TCG respectively) are calculated.

4. For the current condition, the ship displacement characteristics (displacement, D and longitudinal and transverse center of buoyancy, LCB and TCB respectively) are calculated.

5. Equilibrium is considered to be met if the following equations are satisfied:

• W = D

• LCB = LCG

• TCB = TCG

If the above conditions are not satisfied, a new estimation of the ship’s equilibrium position is made and calculations are repeated starting from Step 2.

Extended validation of inLoad results with respect to hydrostatic, stability and strength calculations has been performed against well established ship design software packages.

It has already been demonstrated how the stability calculations can be set to use either pre-calculated stability data (such as the original ship cross-curves) or direct calculations. The two modes affect only the evaluation of the stability graph and table. This means that the ship’s equilibrium is always calculated directly. In order to generate GZ versus angle of heel data though, it is possible to use pre-calculated data, according to the manner these are calculated in the ship’s trim and stability manual. This effectively accelerates the set of compliance checks for each change in the ship status. Alternatively, the user can request to produce more accurate GZ versus angle of heel stability data, by selecting to calculate these data directly. These

calculations take into account the heeling and trimming of the ship: for each angle of heel, the floating position of the ship is sought so that the displacement is kept constant. It is possible that the stability data produced this way, will not coincide with those produced from cross curves data. The reason is that direct calculations take into account the changes in trim and mean draught, while simple calculations don’t. This means that for a particular loading condition, the draughts when the ship is upright and the draughts for the ship inclined to a particular angle of heel are not necessarily the same. Between those two situations, only the displacement is always the same.

It is outlined that calculating the exact stability data for the ship at each change to a loading condition can be much slower: the computational load for each change is in this case approximately multiplied by the number angles of heel required. In most common loading cases, estimating stability from cross curves is sufficient and acceptable as a common practice. Direct calculations are most useful in situations where the ship suffers damage to a tank and more precise calculations may be needed. It is advised that users test the loading conditions using the estimation process. After verifying that the loading condition is acceptable, direct calculations can be turned on for cross checking.

inPlot2D User’s Guide

A first look into inPlot2D plotting library

hroughout this manual, you have many times encountered 2D graphics such as the General Arrangement, stability and strength plots. These plots are based on a common plotting library: inPlot2D. This is a software library developed especially to cover the needs of 2D plotting and graphing. inLoad2D provides, among others, the tools to navigate in a plot, zoom in and out and

manipulate the way plots look.

T You can zoom and pan the plot so as to examine a detail or see the whole image. In all plots, either in drawings like the General Arrangement or graphs, such as the strength graph, you can use your mouse to perform these actions.

" By using your mouse’s wheel (between the two buttons) you can zoom in an out in a plot. Roll the wheel towards you to zoom out or towards the screen to zoom in.

" Right-click on the plot and while keeping the right button down, drag your mouse. You will notice that the plot follows your mouse’s movement. Note that you need to zoom in first.

" Another way to zoom in, if your mouse does not have a wheel, is to press the left button mouse and drag the mouse. You will notice a parallelogram on the screen. This is the zoom window. Whatever you place inside the parallelogram is zoomed in.

# In order to restore the original dimensions of the plot, press the Esc button on your keyboard.

When you right-click on a plot, a popup menu appears. From this menu, you may perform a series of tasks. The first four commands control the sizing of the plot.

% Fit Width resizes the plot to fit into the window’s width

% Fit Height resizes the plot to fit into the window’s height

% Fit Both resizes the plot to fit into the window’s dimensions

% Toggle Expand resizes the plot’s window so as to fill the whole screen. Using Toggle Expand again, restores the original window size.


% Save Image opens a new dialog from where you can save the current plot as an image. To save the image to a file, you need to enter a file name in the File Name field provided. In the same dialog, you can select the format of the image you would like to export. You can choose between Bitmap, GIF, Targa, XPM, PCX, TIFF, JPEG and PNG. These options are available from the File Filter drop-down menu. By default, the dimensions of the original image are used to export the image to a file. These dimensions are automatically input in the Set Width and Set Height fields in pixels. If you want to save the image in different dimensions, you should use these two fields. Note that inPlot2D renders the image in the dimensions you provide. This means that image quality is not affected. If you need to save just the visible part of an image, provided you have zoomed-in, toggle the Select Image Span button to Save Viewable Part.

% Set Zoom raises a ruler that is used to set the zoom factor. Dragging this ruler, automatically changes the zoom.

% Graph Properties is available only for graphs. This command, raises a dialog where you can modify the way a graph is presented.
