The following changes have been made to the Compartmentation task.

Version 2011 R1 (9.1) If two compartments share a common face, you can now move or edit that common face

editing both compartments at the same time. The common face must be defined by points,be coplanar, and be defined the same way (by 2 points or by 4 points). (P3 CP:181838)

S E C T I O N 1

The Compartmentation task allows you to define the functional layout of a ship by creatingcompartments, ship zones, and other volume objects within the ship. Using theCompartmentation task, you can also assign loads and load combinations to volume objects.

Compartments are physical spaces within the ship that cannot overlap, except for some limitedcases where one compartment, such as a fuel oil day tank, is completely enclosed by anothercompartment (such as the main machinery space). In almost all instances, a compartment iscompletely defined in terms of topological boundary relationships with a plate system, a deck, atransverse bulkhead, a longitudinal bulkhead, or a hull shell object.

Ship zones are logical spaces within and around a ship that may or may not physically overlap.In most cases, ship zones are defined by a rectangular bounding box. The properties andspecifications of compartments, ship zones, and other volumes are defined in the reference datain the Catalog task.

You can define the geometry of a volume object in a variety of ways - by two points, by fourpoints, by other surfaces, or by other volumes. You can also create a volume object in the modelby defining a path and projecting a cross-section along the path. In addition to these functions,you can import a SAT file to create compartments.

After creating volumes, you can specify loads that are applied to the volumes. Load folders,spatial loads, unit loads, and load combinations appear on the Analysis tab in the WorkspaceExplorer .

You can start the Compartmentation task by clicking Tasks > Compartmentation. TheCompartmentation task has the following commands:

Select - Used to select objects in the model. For more information, see EditProperties (on page 95).

Create Space Folder - Creates a new folder for the organization of volumeobjects in the model. For more information, see Create Space Folder (on page 23).

Place Volume by Two Points - Defines a volume by selecting two points torepresent opposite vertices of the volume. For more information, see PlaceVolume by Two Points (on page 28).

Place Volume by Four Points - Defines a volume by entering three points todefine a base plane and a fourth point to define elevation or depth. For moreinformation, see Place Volume by Four Points (on page 33).

Create Imported Volume - Imports an ACIS file (.sat) into the model to createvolumes. For more information, see Create Imported Volume (on page 35).

Place Volume Along Path - Places a volume by specifying a cross-section andprojecting the cross-section along a path. For more information, see Place Volume Along Path (on page 37).

Create Volume By Faces - Defines a volume by selecting sufficient boundingsurfaces to create a closed volume. For more information, see Create Volume byFaces (on page 52).

Understanding Compartmentation


20/148

Understanding Compartmentation


Create Mult iple Volumes - Creates multiple compartments in a specified volume.For more information, see Create Multiple Volumes (on page 57).

Merge Volumes - Merges multiple existing volumes into a single new volume. Formore information, see Merge Volumes (on page 65).

Bound by Volumes - Defines a volume from sufficient bounding spaces thatcreate a closed volume. For more information, see Bound by Volumes (on page67).

Create Load Folder - Creates a new folder for the organization of load objects.For more information, see Create Load Folder (on page 79).

Create Load Combination - Combines spatial and unit loads. For moreinformation, see Create Load Combination (on page 81).

Create Spatial Load - Creates a load on a spatial volume. For more information,see Create Spatial Load (on page 84).

Create Unit Load - Creates a load on a point. For more information, see

CreateUnit Load (on page 86).

Export Compartment - Exports a compartment solid body as a .sat file. Thiscommand is on the File menu. For more information, see Export Compartment (onpage 77).

Create Compartments Automatically - Creates compartments through an entireship in one operation. This command is located on the Tools menu. For moreinformation, see Create Compartments Automatically (on page 61).

Update Attributes - Updates the attributes of selected compartments based oncustom code. This command is located on the Tools menu. For more information,see Update Attributes (on page 75).

In addition to commands on the vertical toolbar and menus, the Compartmentation task alsoprovides a custom command, Compart Query Service, which allows you to perform queries onobjects in the model, for example, to find all compartments that are on or cross a deck.


21/148


S E C T I O N 2

All compartments — or volume objects — are placed in the model using information defined inthe compartmentation reference data. Using the reference data workbook, you can createcustom volume objects that fit your specific requirements. Your first step should be to review,edit, and otherwise customize the delivered compartmentation reference data. For moreinformation about customizing the reference data that is delivered with the Compartmentationtask, refer to the Compartmentation Reference Data Guide, available from the Help > PrintableGuides command.

After the reference data is customized, go to the Systems and Specifications task and begin todefine the systems that you want in your model. While you are not absolutely required to createyour systems first, doing so keeps you from having to edit your volume objects after placementto assign them to the correct system.

With the systems defined, use the Grids task to define and place coordinate systems, elevation

planes, and grid planes. Then, use the Molded Forms task to define the basic structure of theship, including: the hull, decks, bulkheads, major openings, stiffeners, beams, design seams,and so forth.

After the compartmentation reference data and the needed systems, grids, planes, and shipstructures are defined, you can begin creating compartments, ship zones, and other volumeobjects in your model.

When the volume objects are defined, you can create load objects, including spatial loads, unitloads, and load combinations.

See AlsoUnderstanding Compartmentation (on page 19)

Compartmentation Common TasksThe following tasks are used frequently in the Compartmentation task.

Customize Reference Data

Create new volume object types by editing the compartmentation workbooks. For moreinformation, see the Compartmentation Reference Data Guide, available from the Help >Printable Guides command.

Organize Volumes and Loads

Create folders to organize volume and load objects. For more information, see Create a spacefolder (on page 24) and Create a load folder (on page 80).

Create Volume Objects

Create volume objects in the model. There are several methods of creating volumes in theCompartmentation task. You can place a volume by two or four points, import volumes, place avolume along a path, create a volume bound by faces, create multiple volumes at once, ormerge volumes.

Creates a new hierarchical folder for organizing your volume objects. You can create foldersto provide a hierarchical storage system for the volume objects that you create in theCompartmentation task. When you select the Create Space Folder command, a ribbon appearsthat allows you to define a parent and name for the new folder. After the space folder is created,

the space folder icon appears on the Space tab in the Workspace Explorer .

The Space tab of the Workspace Explorer displays all the volumes in the workspace in aclassification hierarchy that reflects the various relationships defined for the volume objects. Thecontent represents the current volume objects loaded from the database into the active

workspace. When you select a volume object in the Workspace Explorer , it appearshighlighted with the select color in the graphic view. Additionally, the software defaults to editmode and displays the Edit Volume ribbon, which you can use to modify the selected volumeobject.

You can also right-click a folder on the Space tab of the Workspace Explorer , and thenselect Create Compartment Folder .

See AlsoCreate Space Folder (on page 23)


25/148


S E C T I O N 4

Several methods of creating new volume objects exist in the Compartmentation task. You canprovide two or four points to identify a rectangular cube, or you can select existing boundaries,such as decks or bulkheads, to define the volume. You can also import volumes or place avolume along a path. It is up to the designer to determine which volume creation tools are mostapplicable for the specific requirements of a ship.

Volumes are stored in the model. In a graphic view, a volume object appears as a gray box, bydefault.

In the Workspace Explorer , a volume is represented by an icon on the Space tab. You canlocate and manipulate volumes quickly and easily in the space hierarchy.

You can use SmartSketch points when you create volume objects. When you associate a set ofobjects to a volume point with SmartSketch relationship indicators, if the associated objectschange, then the volumes update accordingly. For example, if a volume is connected to a gridintersection or a reference plane and the grid or plane is moved, the associated volume is addedto the To Do list, and you can update the volume size.

Another example is when the boundaries of volumes are defined by plate systems. When thestructural designers move the plate systems that are used to define compartments, the softwareplaces the volumes on the To Do list for updates.

Most volumes created in this task do not update automatically, and therefore, must bemanually updated. You should check the To Do list regularly for out-of-date volumes, especiallyin a concurrent design environment.

Merging o r Splitting Volumes

After you create a volume, you can add to or subtract from the volume using booleanoperations. You can merge the volume with other volumes. You can also split the volume intomultiple volumes. When you perform these operations, the software changes the type for theinput volume(s) to a void space if the input volume has the same type as the output volume(s).

For example, when you click the Create Multi ple Volumes command, you select an existingvolume and then select the inner faces. The existing, parent volume is not deleted, but it ischanged to a void space if the parent is the same type as the children volumes.

Creating Volumes by Points

When doing the preliminary design of compartments and ship zones, it is often convenient to

quickly create volumes by two or four points. Using the Place Volume By Two Points

command and Place Volume By Four Points command, you select points in the model todefine a volume.



26/148



For the Two Points command, you select points (bottom- front-left and top-right-back points) atthe corners of the space. For the Four Points command, you first select three points to definethe base planar surface of the volume, and then you select a point to provide the necessaryelevation to extrapolate the plane in three dimensions.

Alternatively, you can enter the X-, Y-, and Z-coordinates of the points using the PinPoint

command. Either way, these volumes are not linked or associative to any existing geometry.Only their location coordinates are relative to the defined origin of the model.

You can also use the boolean operation buttons on the ribbon to add or subtract volumes fromthe overall volume.

For more information about creating a volume by two points, see Place Volume by Two Points (on page 28); for information about creating a volume by four points, see Place Volume by FourPoints (on page 33).

Creating Imported Volumes

The Compartmentation task allows you to quickly create volumes by importing an ACIS file intothe model. For more information, see Create Imported Volume (on page 35).

This functionality is similar to the Import Plate System command in the Molded Forms

task. For more information, see the Molded Forms User's Guide, available with the Help >Printable Guides command.

Placing Volumes along Paths

In the Compartmentation task, you can create customized volumes in the location that you need

and with the shape that you need using the Place Volume Along Path command. Thiscommand is especially useful for volumes that need to have an unusual shape or that mustnegotiate around specific objects in the model. For example, if you need to leave adequatespace for equipment to reach a particular location, the Place Volume Along Path commandallows you to specify the path where the equipment needs to travel as well as the appropriateamount of clearance that must be left on all sides. One application of this command is a fireevacuation route.

When you place a volume along a path, a two-dimensional cross section is projected along thepath that you specify in the model to create the volume. The path determines the location of thevolume in the model. The cross section, on the other hand, defines the shape and dimensions ofthe volume.

The following picture shows a path (yellow) and a rectangular cross section projected along thatpath, with the resulting volume shown in green.

Defining Paths

When you define the path along which a cross section is projected, you can choose from a

straight line or an arc by three points . Or, if you want to break the path at a particular


27/148



point, you can select No Line . You can also control characteristics of the path by specifyingthe types of turns (bend, cornice, or chamfer), the dimensions of the turns, and the plane for thepath.

Defining Cross Sections

When you define the cross section for the volume, you can select from a standard set of crosssections defined in the reference data, or you can sketch your own two-dimensional crosssection.

When you use a standard cross-sectional type, you can change the dimensions and the cardinalpoint of the cross section on the Cross-Section tab on the Volume Properties dialog box. Thecardinal point of the cross section is important in determining the shape and location of theresulting volume. The cardinal point is the point where you want the software to attach the crosssection to the path. All standard cross section types have cardinal points from which you canchoose.

For example, in the following picture, you can see that the cardinal point (represented by a blackdot) is located in the center of the cross section. If the cardinal point were moved to anotherlocation, the resulting volume would be different.

When you sketch a cross section, you must sketch the cross section on the two-dimensionalplane that is orthogonal to the first leg of the path. The software displays this plane, which isperpendicular to the path, as you sketch the cross section. The cardinal point is also displayedas you sketch.

Editing Customized Volumes

After creating customized volumes, you can edit them. The edit path ribbons allow you to modify

the arcs, turns, or straight segments that are part of an existing path, either at placement orafterward.

For more information about creating and editing customized volumes, see Place Volume AlongPath (on page 37).

Creating Volumes by Faces

Another way to create a volume is by selecting plate systems or reference planes in the model.For more information, see Create Volume by Faces (on page 52).

While using the Create Volume by Faces command, you select the faces for thecompartment. The software determines if there is any ambiguity and if so, allows you to chooseamong the resulting volumes.


28/148



When you are creating a volume by faces, it is often helpful to select a specific coordinatesystem (grid system). The Plate Filter box on the ribbon allows you to select a grid system forthis purpose. For more information, see Create a filter for a grid system (on page 60).

Place Volume Along Path

Sketches a path in three-dimensional space, defines a cross-section, and projects thecross-section along the path to define a volume. The path can consist of straight lines, arcs, or

even breaks in a line.While using this command, you can associate the volume with a design specification from thecatalog database. You can also add or subtract volumes to or from the overall volume.

This command is especially useful for volumes that need to have an unusual shape or that mustnegotiate around specific objects in the model. For example, if you need to leave adequatespace for equipment to reach a particular location, the Place Volume Along Path commandallows you to specify the path where the equipment needs to travel as well as the appropriateamount of clearance that must be left on all sides. One application of this command is a fireevacuation route.

When you place a volume along a path, a two-dimensional cross-section is projected along thepath that you specify in the model to create the volume. The path determines the location of thevolume in the model. The cross-section, on the other hand, defines the shape and dimensions ofthe volume.

The following picture shows a path (yellow) and a rectangular cross-section projected along thatpath, with the resulting volume shown in green.

Defining PathsWhen you define the path along which a cross-section is projected, you can choose from a

straight line or an arc by three points . Or, if you want to break the path at a particularpoint, you can select No Line . You can also control characteristics of the path by specifyingthe types of turns (bend, cornice, or chamfer), the dimensions of the turns, and the plane for thepath.

Defining Cross-Sections

When you define the cross-section for the volume, you can select from a standard set ofcross-sections defined in the reference data, or you can sketch your own two-dimensionalcross-section.

When you use a standard cross-sectional type, you can change the dimensions and the cardinal

point of the cross-section on the Cross-Section tab on the Volume Properties dialog box. Thecardinal point of the cross-section is important in determining the shape and location of theresulting volume. The cardinal point is the point where you want the software to attach thecross-section to the path. All standard cross-section types have cardinal points from which youcan choose.


38/148



For example, in the following picture, you can see that the cardinal point (represented by a blackdot) is located in the center of the cross-section. If the cardinal point were moved to anotherlocation, the resulting volume would be different.

When you sketch a cross-section, you must sketch the cross-section on the two-dimensionalplane that is orthogonal to the first leg of the path. The software displays this plane, which isperpendicular to the path, as you sketch the cross-section. The cardinal point is also displayedas you sketch.
