CHAPTER 1

1 Introduction

The PSI application allows you to create stress groups from existing pipe lines within the PDMS Designapplication. When a stress group has been created the PSI application will create a CAESAR II CII formatfile, which can be selected in CAESAR II and converted to a CAESAR II C2 format file.

The stress engineer can then perform stress calculations on the transferred stress group.

Once the stress engineer has finished the analysis; a report file is create a (with extension .out) and aCAESAR II neutral file updated showing the modified pipe. These files can be then be imported back into

AVEVA Plant Design (PDMS) to assist the Piping Designer in updating the 3D model to match the results.

1.1 Aim

This document provides guidance to the Piping Stress Engineer or AVEVA Plant Design (PDMS) Designeron how to create and configure stress groups using the Pipe Stress Interface (PSI) application. It isacknowledged that there may be more that one person involved in this process.

1.2 Objectives

At the end of this training, you will: -

Be able to transfer Piping information between AVEVA Plant Design (PDMS) and CAESAR II.

1.3 Prerequisites

It is assumed that the Piping Stress Engineer has a basic understanding of the AVEVA Plant Design(PDMS) software and that the AVEVA Plant Design (PDMS) Designer has a basic understanding ofCAESAR II.

1.4 Course Structure

New Stress Group Name form is displayed.

Enter the name of your new stress group /150-B-6-GROUP and press OK.

Note: - To close the window without creating a new stress group select the Dismiss button

Stress Group names containing slashes are not valid and will cause later problems if used.

In some cases the Stress Group Name may be based on a networks e.g. “STEAM_PIPES” orCalculation Numbers e.g. “STRESS-22”

3.3 Existing Stress Groups

Once you have created a new Stress Group it will be displayed in the Existing Groups box on the PipeStress Interface and in the Design Explorer hierarchy if displayed.

3.4 Adding and Removing Branches in the Stress Group

Stress Groups hold a series of branches that must be in the same network.

3.4.1 Adding Branches to the Stress Group

To add branches to a Stress Group, select the Stress Group you want to add to by clicking on it in theExisting Groups list and then click the Add/Remove Members button on the Pipe Stress Interface. The Pipe

Stress Interface now becomes greyed out and inactive.




13

Note: The lowest level to add to a Stress Group is a branch; branches can be split if it is necessary tostress part of a branch.

Select the branches to include in the Stress Group by graphically selecting them using the left mouse button.

Select /150-B-6 once selected use the Escape <esc> button to exit the Graphical pick.

Branches to include in a stress group have been selected in red. But this colour might vary depending uponyour configuration settings.

3.4.2 Removing Branches from the Stress Group

To remove a branch which you have selected, select it again and you will be prompted with a choice toremove the selected branch from the stress group.

Once you have finished selecting the branches to include in your stress group press Escape <esc>. ThePipe Stress Interface form will now become active.




14

www.aveva.com

The branches that you selected to include in your stress group should now be listed in the Group Membersbox

Members can be added or removed from group at any time by pressing the Add/Remove Members button.

3.5 Rebuild Selected Group

The Rebuild Selected Group button allows you to rebuild and refresh members of the currently selectedgroup.

I confirmation prompt will be displayed.

3.6 Find a Group

The Node Details form has two radio buttons. Selecting All Nodes displays all node on the form (inactiveand active nodes), selecting Active Nodes just displays active nodes i.e. those nodes with a node number.

5.4 Renumbering Nodes

Nodes of a stress group can be renumbered by pressing the Renumber Nodes button located on the NodeDetails Form.

5.4.1 Single Node Renumbering

To renumber a single node, select the appropriate node in the list 30 and enter a new node number in theNew Number text box 31. Press Update Numbers to view the changes and then press Apply to save the

changes.

Note: N.B If you choose a node number that is already in use then you will be asked if you want torenumber all subsequent nodes; these will be renumbered according to the increment value in theIncrement text box.




22

www.aveva.com

5.4.2 Cascading Node Renumbering

When you select a node to be renumbered using the Cascade option, all subsequent nodes are alsorenumbered according to the increment value in the Increment text box. Select Node 40 Increment 20 SelectCascade and Update Numbers and Apply.

5.4.3 Reset Button

This resets all nodes to their original node numbers.

Note: this only works if the Apply button has not been used

CHAPTER 6

6 Checking the Stress Group for Errors

The Check Group button on the Output/Input tab checks the selected Stress Group for Datacon and Nodeerrors.

When the Check group button is pressed it displays a tabbed window. Results from the checks aredisplayed under the appropriate tab.

6.1 Datacon Errors

The Datacon errors tab displays Data Consistency errors for each branch in the Stress Group.




24

www.aveva.com

6.2 Node Errors

The Node errors tab shows problems such as the componentweight not being set. These errors should be rectified before thepipe is sent to be stressed.

6.2.1 Node Errors – Temperature and Pressure 2 – 9

CAESAR II will allow up to 9 temperatures and pressures bydefault the PSI Interface only transfers one temperature and onepressure so Temperatures 2 – 9 and Pressure 2 – 9 can beignored.

6.2.2 Node Errors - Insulation

If no insulation spec is set on a branch Error in Insulation (2,114)

=0/0 has no attribute will be displayed if the pipe has noinsulation this can be ignored.




25

www.aveva.com

6.2.3 Node Errors – Weight

If the weight of a component such as an instrument is not set, then an error in the Node Errors tab will bedisplay:

For example: - Unable to Find Weight for INST /FE-117INST =15392/5691

As there is no weight is the catalogue for this, it can be set locally in the design by use of a UDA (User-defined Attribute) called PSIWEIGHT.

The PSIWEIGHT attribute’s value remains persistent once set and overrides the catalogue value.

To set the PSIWEIGHT UDA modify the component’s attributes by selecting: Modify>Attributes from themain menu.

Note: To see changes to the list of Datacon and Node Errors, refresh the Stress Group before pressing

the Check Group button. This will insure that all changes to the Stress Group are up to date. Followinga Stress run no errors will be displayed without rebuilding the selected group.

6.2.4 Setting a temporary weight for a Stress Run

In the Existing Group box, right-click on the selected stress group and select Show Node Details from thecontext menu.






27

www.aveva.com

Exercise 4 – Checking Stress Group Errors

Check the Stress Group for Errors as described above,

Datacon Errors

The Datacon Errors can be ignored, the bend has a skey catalogue errorthat should be corrected in the catalogue but this will not effect the pipestressing.

The pipe attachments have attypes that will be ignored by t the PSIinterface and will not be passed over to Caesar II.

Node Errors

PSI only transfers one Temperature and one Pressure Temperaturesand Pressures 2 – 9 can be ignored.

Insulation Error is shown because the pipe has no insulation so can beignored.

The weight error on the Bend can be ignored as the Bend used is

manufactured from Pipe and would not have a weight set.

The attas on this pipe are not being passed to Caesar II so the weight ofthem need not be set.

CHAPTER 7

7 Pipe Stress Interface Defaults

7.1 The Pipe Stress Interface toolbar

The PSI toolbar is located under the main menu bar.

Each icon on the PSI toolbar and its assigned action or purpose is listed in below.

Show Pipe group Modification form for the current stress group.

Modify Stress Defaults

7.2 Pipe Stress Interface Defaults

The PSI defaults form allows the user to configure PSI to suit the user’s project data. This can be configured in many ways so it is important to provide facilities to use this data rather than make project changes to suitPSI.

The defaults file is principally used to tell PSI where to extract information and what units to expect, but italso defines how PSI works in the user environment. We have already discussed the use of the Node FormDisplay Columns.

When the Modify Stress Defaults icon is pressed from the PSI toolbar, the Stress Interface Defaultsform is displayed

.




30

www.aveva.com

The Stress Interface Defaults form has five tabs:

Database UnitsInterface Settings

ExpressionsRestraint DataNode Form Display Columns

For information on how to use the PSI defaults form, please see the TM-1501A - Pipe Stress Interface(PSI) (Admin).

Exercise 5 – Pipe Stress Interface Defaults

Investigate the units being used on the project and if necessary change them to the values shown above.

CHAPTER 8

8 PDMS to CAESAR II (5.1)

8.1 Creating a CAESAR II Neutral file

To create a CAESAR II Neutral file for a selected Stress Group, press the Write Data to File button on theOutput/Input tab.

It is now very important to do a Savework Design > Savework immediately after creating a CAESARNeutral File so that all data relating to the Stress Group is saved within PDMS.

Once the button has been pressed three folders called input, output and logs are used to store the data.

They are located in the same area as the project directories e.g. C:\ProjectPath\Project\Sampsi where thename of the project is Sam.

The files contained within these folders are named according to the name given to your Stress Group.

The input folder contains the newly created CAESAR II Neural File (*.cii) which can be input into Caesar II.

The output folder contains an xml file which contains pipe stress data exported from PDMS in a predefined

schema.

The logs folder contains a HTML reports viewable via a web browser: _log.html which contains informationabout the conversion from the *.xml file to the Caesar II Neural File. The _log.html contains versioninformation for the .cii converter, and also any messages to do with the running of the conversion process – it is a good place to look if things go wrong. It also contains information about the PDMS elementstranslated, and any assumptions and default values used (for example missing weights or wall thicknesses).The stress engineer may find it useful to have a look at this file.

9.4 Converting a CAESAR II Input file to a CAESAR II Neutral File

In order for PDMS to determine if any changes have been made to the stress pipe within CAESAR, thecurrent piping input file needs to be converted to a neutral file.

N.B It is important that this step is implemented either directly before the producing the report file ordirectly after, so that the representation of the pipe in consistent in both files.

Select Tools>External Interfaces>CAESAR II Neutral File… from the main menu.

A Neutral File Generator box should now be displayed.

Select the second radio button labelled “CAESAR II Input File to Neutral File”.

Press the Browse button and navigate to the appropriate 150-B-6-GROUP.C2 file Select Open.

CHAPTER 10

10 Modifying and Adding Nodes in CAESAR II

10.1 Node Modification

Pipe /250-B-5 has been added to Stress Group /250-B-5-GROUP and transferred to CAESAR II asdescribed previously it has had its nodes numbered starting at 10 in 10 increments.

Once in CAESAR II the Nodes 30 – 40 and 120 – 130 distance is changed from 610mm to 910mm andNodes 70 – 80 is changed from 693 to 393.

This is done using the CAESAR II Piping Input Form

Select Input > Piping or use the Piping Input Icon

Use Next element to select Node 30 – 40 Change DX: from 610.000 to 910.000.

Continue the process to change Nodes 120 – 130 DX: from 610.000 to 910.000 and reduce 70 – 80 from693.030 to 393.030 mm.

Nodes are displayed using Node Numbers Icon onthe Plot Tools toolbar.

Pipe lengths can be displayed using the Show

Lengths Icon on the Plot Tools toolbar.




46

www.aveva.com

Remember you must stress the Stress Group using for example the Batch Run save the displacements tothe output directory and Convert the modified input file and copy the modified file to the Output directory.

The Updated Stress information can now be transferred back and displayed in AVEVA Plant Design (PDMS)

Convert and Read Stress Data

The above shows the original and modified Stress Group displayed in AVEVA Plant Design (PDMS)

10.2 Adding Nodes in CAESAR II

New nodes that have been added in CAESAR e.g. an expansion loop will be displayed in PDMS

Original PDMS CAESAR View with added Nodes Returned PDMS View

In the example shown above the nodes have been numbered in 100 increments this has been done so thatextra nodes can be added to create the elbows. Each elbow would require 3 nodes.

New nodes must be entered and Numbered in order on the Piping Input Form using the Insert Icon

The nodes illustrated above have been input as bends with a radius of 457.200 mm.

Exercise 9 – Adding Nodes in CAESAR II

Create a Stress Groups and add additional Nodes as illustrated above to form a loop in the pipework.

CHAPTER 11

11 Adding Pipe Supports

Pipe supports can be added both in AVEVA Plant Design (PDMS) and passed to CAESAR or in CAESARand passed back to AVEVA Plant Design (PDMS) for inclusion original pipe.

As will all cases the original pipe is not modified.

11.1 Adding Pipe Supports in AVEVA Plant Design (PDMS)

This is included as an example it is expected that the Designer placing Pipe Supports in AVEVA PlantDesign (PDMS) in fully conversant with support design using PDMS.

Add Pipe /40-B-10 and SCTN /F4G4-1 and /F6G6-1 to the screen as shown below in a Iso2 view.

The following example shows the pipe /40-B-10 with a support that has been added using MDS.

The MDS pipe support system is covered in TM-1210 AVEVA Plant (12 Series) Multi-DisciplineSupports.

Attas can be added as shown below: -




50

www.aveva.com

Using the Pipe Components Creation Form create a GEN typeatta on branch 40-B-10/B1 each of the sections.

The Atta can be placed onthe pipe and aligned usingalign with feature

11.2 Adding Pipe Stress Node Information

Regardless of how the support was created the following Node information must be added.

Use Modify > Attributes on the Atta to change the following:

SPKBRK true

:NodeType 15

:NodeStiff 1751270031350




51

www.aveva.com

Note the Node Stiffness is set to 1751270031350 this is a default value in CAESAR it can be changedbut should not be set to 0.

Node Type 15 is +Z or a free rest as indicated in the table below.

If the support has been created using MDS then the structural attachment should not be transferred toCAESAR. This is done by setting the attype of the support to HANG.

Structural attachments have a name similar to /PS-00001/SREF navigate to all SREF Attas andset attype HANG.

The second atta can be created using create copy offset and then position using Position > Component >Through

Ensure that you have a pipe support on each beam as shown below.

11.3 Pipe Support Node Types

The following table shown the PSI node types for use with Restraints

1 = ANC2 = X3 = Y4 = Z5 = RX6 = RY7 = RZ8 = GUI
