Creating a Vessel
You have defined your tensioning system and you can now proceed to creating a Vessel component to model the vessel. To create the Vessel, right-click the Vessel folder and select New > Vessel > Vessel. Rename this component Lay Vessel.
A vessel profile may be optionally associated with the vessel for illustrative purposes, appearing in all animation files generated by analyses that include the vessel. Three options are provided – Standard, TLP and User. The first of these, Standard, provides a generic vessel profile. The second option requests the generation of a generic TLP profile, while the last option allows you to input your own customised vessel profile. Select Standard.
Set the appropriate vessel dimensions to the values outlined in Example 3 by pressing the Properties button and entering the data as shown in the figure below. The User Specified Profile button pertains specifically to User profiles and is disabled in this instance.
Select the relevant Stinger component, Stinger, in the Stinger drop-down list and set the stinger origin location using the values outlined in Example 3 by pressing the Location button and entering the data as shown in the figure below. The stinger origin is defined with respect to the vessel origin, which is specified in the Model component. The stinger angle of 180º means that the stinger points directly off the stern of the vessel.
You may now proceed to specifying the location of the supports on the vessel deck, by pressing the Support Locations button. This displays the spreadsheet-type dialog shown in the figure below.
Vessel Support Locations
The drop-down list in the first column of this dialog provides a list of all the Support and Tensioner components currently defined in the project. In the first row of the Support Name column, select Tensioner and in the second row select V-Rollerbox. Subsequent rows default to the same entry, so it is not necessary to reselect V-Rollerbox for subsequent rows. Specify the support locations in the second and third columns as outlined in Example 3. You may leave the Z-Coordinate column blank, as you’ll define the pipeline in the global X-Y plane for this example. The Angle column is optional and may be left blank, so the orientation of each support is aligned with the vessel deck. The Fine Tune Offset and Fine Tune Direction entries, intended for later tweaking of support position may be ignored at this time.
Once the support locations have been fully specified, the dialog will appear as shown in the figure below.
Completed Support Locations
The Component View for the completed Vessel component is as shown in the figure below.
