Model - Layout & Viewing Model

Previous page Next page

The component view for a new Model component is shown below.

model

The Model component window is organised as follows:

The component type and component name are displayed on the top left corner of the component view.

The three buttons called Add, Remove and Properties enable you to modify the list of model sub-components.

The Seabed drop-down list enables you to select the seabed to use for the model from a list of the seabeds that are currently defined for the project.

The Water Depth button enables you to specify the water depth for the model.

To the right of the Water Depth button there are three buttons that you can use to choose between a plan view, an elevation view or an end view of your model. You can switch between views at any stage in the process of building your model.

The list of Model sub-components such as lines or vessels is displayed in the left pane of the window.

The right pane of the window displays a preview of the model as it evolves. The preview is automatically updated to reflect additions or alterations to the model or its sub-components. In particular the pane displays the following:

oThe global XYZ axis system in the top left corner of the pane.

oA blue line to indicate the water level.

oA red line to indicate the seabed.

oA cross-hair to mark the origin of the global axes, labelled Origin.

oVertical and horizontal scale bars indicating dimensional values in the vertical and horizontal directions with respect to the global origin.

oA cross-hair to mark the vessel origin (VO), if or when you include a vessel in your model.

oA cross-hair to mark the vessel reference point (VRP), if or when you include a vessel in your model.

oA cross-hair to mark the stinger origin (SO), if or when your model includes a stinger.

oCross-hairs to mark the location of tangent points (TP) at the start of designated areas of pipe curvature, if specified on the Vessel component.

oCross-hairs to mark the location of centres for radii of curvature (RAD) that are used in combination with tangent points to create areas of pipe curvature, if specified on the Vessel component.

The significance of the last four cross-hairs referred to above is explained in later articles.

The Advanced button enables you to specify a tolerance value called the Schematic Solver Tolerance as well as other inputs for the calculation of certain connection points. See the article entitled ‘Specifying Advanced Options’ for more information.

The Support Data button enables you to export a summary of the support offsets as calculated/applied by the UI to a csv file. See article entitled ‘Exporting Support Data’ for more information.

The Show Radius of Curvature checkbox, when checked, will display the individual radii of curvatures on the Model Viewer. They are colour coded with matching colour coded RAD tooltips to enable easy visual inspection of the vessel radii of curvature specification and the subsequent support mapping to the defined curvature.

 

Adding Sub-components

There are two ways to add new sub-components such as lines or vessels to your model.

You can click on the appropriate sub-component folder in the sub-component list and then click the Add button.

You can double-click on the appropriate sub-component folder in the sub-component list.

Either action will open an appropriate menu, allowing you to input relevant properties, for example, the position of a vessel.

You can add the same component more than once into a particular model. For example, if you have two identical cables there is no need to create two separate Cable components to represent them. The model creates a unique name for each instance or occurrence of a component added to the Model component. These names are automatically generated from whatever the component is called at the moment you add it to your model. If you later change the name of the component, the names describing instances of that component in the model are not updated, but you may edit them yourself at any time.

 

Modifying the Properties of Sub-components

When you add a sub-component, you can modify the properties of the component at any time by selecting the component in the sub-component list and pressing the Properties button. Alternatively, you can double-click on the component in the sub-component list.

 

Removing Sub-components

You can remove existing sub-components from the model at any time using the Remove button.

 

Viewing Your Model

The Model component contains the following facilities to make it easier to navigate and debug your model, if necessary:

When you select a sub-component in the left pane, the sub-component is highlighted in a different colour in the right pane view.

If you hover with the mouse over a sub-component in the right pane, the name of the sub-component is displayed as a tooltip.

The Show Radius of Curvature checkbox in the bottom right-hand corner will display colour coded vessel radii of curvature in the Model Viewer to enable additional visual assessment of how supports are mapped onto the curvatures if they have been specified using the Vessel component.

These facilities are illustrated in the figure below, where the selected pipeline is highlighted in cyan and the name of the pipeline is displayed as a tooltip.

Zooming and Panning

The Model component allows you to zoom in on part of the model to allow you to examine the fine detail more closely. Position the mouse in the preview area in the right pane and left-click. The image zooms in by 50%, and the point at which you clicked the mouse becomes the centre of the screen. To pan out again, right-click. Again the point in the model where the mouse was positioned moves to the centre of the screen.
