CHAPTER 2

2 MDS: Basic Concepts of a Support

The Multi Discipline Supports (MDS) application is used to create modify and delete the various types of support required during the design stages of a project. MDS is based on an engineering standard that is configured to the projects requirements.

2.1 Glossary of Terms

The discipline of supports brings together other disciplines and the terms used to describe the same item often leads to confusion. This section tries to explain some of the common terms used.

Ancillary Used to describe an attachment on a line, this could be a shoe, u-bolt, etc.

Atta This is the AVEVA Plant type for an attachment on a line.

Base Support This is a support consisting of a piece of pipe welded or clamped to the line. See Dummy Leg, Dummy Extension and Trunnion.

Cradle A wrap around the pipe to protect the line, often used in conjunction with shoe.

Datum Atta A term used by MDS to describe the first line added to the support. Dummy Leg This is a support consisting of a piece of pipe welded or clamped to

the line. See Base Support, Dummy Extension and Trunnion.

Dummy Extension This is a support consisting of a piece of pipe welded or clamped to the line. See Base Support, Dummy Leg and Trunnion.

Fixed Hangers A support consisting of an attachment to the line for instance a clamp, a hanger rod and a connection to the steelwork. The vertical height of the hanger is not flexible and is a fixed length. This is similar to a variable hanger support without a variable effort spring.

Framework A configuration of steelwork supporting one or more lines.

Framework Template A term used by MDS to describe the available configurations of steelwork.

General Supports A single support with no associated support steelwork. For instance a u-bolt attached to a main structural member on a pipe rack.

Hanger Templates A term used by MDS to describe the available configurations of fixed and variable hangers.

Repad A reinforcing pad often used with other support types such as trunnions, shoes etc.

Special Support A configuration of steelwork that is not available in the configuration of steelwork supplied with MDS.

Sref Atta A term used by MDS to describe the steelwork reference atta used to store the reference to the steelwork standard used.

Trunnion This is a support consisting of a piece of pipe welded or clamped to the line. See Base Support, Dummy Leg and Dummy Extension. Variable Hangers A support consisting of an attachment to the line for instance a clamp,

a hanger rod, a variable effort spring, and a connection to the steelwork. The vertical height of the hanger is flexible and is a variable length dependant on the movement of the line. This is similar to a fixed hanger support with a variable effort spring.

Vessel Supports Support used to support a line that is attach to a vessel.

Wear Pad A wrap around the pipe to protect the line, often used in conjunction with a shoe

If you find that a term that you use personally use or your company uses and it is not included in this list then please inform you instructor who will include it in future courses.

2.2 Framework Support

The design hierarchy for a framework type support is shown in the preceding diagram. In principle, each support owns a structure and at least two attachment (atta’s) elements. If the support has more than one design element on the support each pipe will have an atta placed within its hierarchy. The shaded boxes are the project design databases, and the un-shaded boxes on the right are the /MDS/TEMPLATES database which stores the available configurations for the project.

2.3 Hanger Support (Fixed and Variable)

The design hierarchy for hanger type support is shown in the preceding diagram. In principle, each support owns a rest element stored under the selected pipe with hang elements containing the hanger components. This is referenced to the atta in the pipe and a fitting within the steelwork member. The shaded boxes are the project design databases, and the un-shaded boxes on the right are the /MDS/HANGERS database which stores the available configurations for the project if the MDS hanger interface is being used. If a manufacturer’s interface is being used then this database in not used and a manufacturer’s project will be used.

2.5 Trunnion Support

The design hierarchy for a trunnion support type is shown in the preceding diagram. In principle, each support is a branch created within the selected pipe. The branch will contain atta elements that are notes, a makeup piece to change the bore and any non-tube lengths if applicable and the trunnion members such as base plates.

(16)

www.aveva.com

2.6 Support Group

A support group consists of a combination of a single framework and a hanger or hangers. The hierarchy used is the same as for frameworks and hangers but the naming convention uses an array identifier to identify a group. The support is then created as a single support name and the MDS ADP drawing details the support on one drawing.

CHAPTER 3

3 Entering the MDS Application

This chapter explains how to enter AVEVA Plant and Start the MDS Application

3.1 MDS Application Pre Requisites

The Multi Discipline Supports application will be entered as long as the pre requisites below are met. • The MDS design templates site - /MDS/TEMPLATES exists in the current MDB

• The MDS application specification - /MDS exists in the current MDB • Valid piping, HVAC or Cable Rack zones exist.

• MDS UDAs are included in the MDB

By default MDS will locate the respective zones by the purpose attribute of piping zones being set to PIPE, HVAC zones set to HVAC and cable tray zones being set to TRAY. You will be unable to enter the MDS application if there is nothing to support.

The recognition of how MDS finds the respective zones is controlled in the MDS Catalogue. Please refer to the MDS Administration Guide for more information.

3.2 Entering an AVEVA Plant Design Session

CHAPTER 4

4 Multi Discipline Support Application Defaults

This session explains the settings and use of the MDS application defaults.

When MDS is entered the MDS support designer loads a series of defaults for use. Some of these defaults are settable by the support designer for the session. This section explains these settings, what they are used for and if the support designer can set them for the current session.

The MDS Application Defaults form may be invoked either from the MDS Application main menu toolbar icon or from the MDS Application main menu option shown below.

(20)

www.aveva.com

1. Creation Zone, the support designer may modify the current setting of the zone where all support

structures will be created.

2. Pipe Clearance, this is value used by the application when creating frameworks using a clearance value.

CLEARANCE

Note: the extremities of the support are determined by the

geometry of the atta and not the pipe O.D.

3. Maximum Pipe Slope, this is the value used when checking if a pipe is horizontal, this value may be decreased but not incresed above a 1/10 slope.

1

n

MAXIMUM SLOPE = 1/n Max = 1/10

4. Steelwork Overlap, this is the value used when overlapping steelwork when creating frameworks.

(21)

www.aveva.com

5. Maximum Packing Distance, when a pipe is placed on a support this value is used to check that the

distance between the steelwork and the botton of ancillary is not exceeded.

MAXIMUM PACKING DISTANCE

6. Maximum Packing Overlap, when a pipe is placed on a support this value is used to check that the negative distance between the steelwork and the bottom of ancillary is not exceeded.

MAXIMUM PACKING OVERLAP

7. Maximum Trunnion Length, when creating trunnion types TT01 to TT03 this value is used to check that the maxiumum length is not exceeded. Standards from TT04 and above have their own setting for each standard.

8. Maximum Pivot Angle, this value is used to check that the angle between the horizontal hanger and a sloping pipe is not exceeded.

9. User Warning Angle, if this value is exceeded and the maximum piviot angle is not the support designer will be given a warrning message.

10. Minimum Rod Length, the support designer may not set a rod length that is less than this value. This is only for standard SP02. When using the FH and VH standards it will use the value set in the manufactures catalogue.

(22)

www.aveva.com

11. Maximum pipe angle, this is used to stop the addition of pipes to a framework that is not within the

angle specified from the axes of the datum pipe.

MAXIMUM PIPE ANGLE (Degrees) DATUM PIPE DIRECTION PIPE IDENTIFIED TO BE SUPPORTED ON FRAMEWORK

PLAN VIEW OF SUPPORT AND ASSOCIATED PIPES

12. Special Number Prefix, A special may be identified by a special number other than its name, this value sets the prefix used.

13. Special Number Unique, A special may be identified by a special number other than its name, this value determines if this number is unique throughout the project or if it can be used again.

14. Transport prefix, if when producing a support drawing the support name starts with this value the drawing will have a note added as defined in item 16 to each view title.

15. When a support is being used, a special drawing level is used to make graphical aids appear this value is used when re displaying the elements to the drawlist.

16. This contains the text used in item 14.

17. This can be used when identifying fixed tube piping.

18. When creating joints, this values determines if the support designer can create joint geometry or not. 19. When modifying a support this detmines if a message is used when MDS deletes the joints.

20. This is used as the value when checking joint eccentricity.

21. This is the setting used when a support framework position is controlled using the flange gap functionality. This will only be active when create by cursor is used. The ID1 setting are the settings used for the first identified element and ID2 for the second.

22. When this button is selected the default file DES-SUPP-DEFS is loading overriding any user modified values.

CHAPTER 5

5 Multi Discipline Support

This Chapter explains how to create a Multi Discipline Support to include PIPES, HVAC, Ducting and CABLE RACKS/TRAYS. You can change the ancillary supports content and the design of a Multi-discipline Support.

The creation of support framework for HVAC, Cable Tray and Vessel Supports follow the same process as Multi Discipline Supports.

5.1 Creation of a Multi Discipline Support

Creation of a Multi Discipline Support may be invoked either from the MDS Application main menu toolbar icon or from the MDS Application main menu option shown below.

The Multi Discipline Frameworks form will be shown

(24)

www.aveva.com

1. Name At this point the support designer may set the name of the support by either:-

Typing the name of the support in the name or 2. Use the MDS Auto Naming facility.

3. The support designer may reselect the default creation zone.

4. After the user has selected the support name to use, they may decide that this support framework is to be used as a support group.

5. Support Filtering Icons can be used to reduce the number support selections. 6. Displays an indication of the reduced selection set.

7. The support designer selects the support type they wish to use

8. The support designer can view and browse through the available standards. 9. The support designer can type the name of the support for example FT09.

After the support designer has completed the name and selection of the standard in list 7 they select the OK button to display the standards creation form.

5.2 MDS AutoNaming

The MDS AutoNaming facility is a project wide facility enabling multiple support designers to create supports in sequential order. The default file DES-SUPP-NAMES is selected by default on entry to the application. The support designer may select different default files to use.

L

Note! MDS does not allow the use of a full stop within its name. This is because subsequent support atta members are named by MDS as <Support Name>. Integer.

To modify select or query the default file being used select the Settings>MDS AutoNaming… menu pick from the main bar menu or right click on the MDS Auto Name button on the Multi Discipline Supports form. Either of these will display the following form.

The support designer can then select a new default file if required or reset the index being used. The format of the name in created by the use of:

Prefix The prefix to be used in the support name

i.e. PS

Index The sequential index

Suffix The suffix to be used in the support name Index width The width of the index value, this will add

preceding zeros if the generated number width is less that the index width

Min Index The minimum index number that this naming file will use.

Max Index The maximum index number that this naming file will use.

The prefix and suffix may be a text string or PML expression enabling the use of attributes etc to be used in the support name.

(25)

www.aveva.com

L

Note! The details of how MDS AutoNaming is configured are covered in the MDS Administration course.

5.3 Initial Creation

This example uses support framework standard XFT09 using Autoname then /A-FT09-1.

The following Items have been added to the display:

Pipes /6”-A150-1002 and

/6”-C150-1003

HVAC /HVAC-1

Electrical Tray /TRAY2

Steelwork /MDS-STRUCTURES-1-F1

Select Multi Discipline Support

Select Autoname

The Name field will be populated with the next available Name which can be changed as required.

For the purposes of the training we will rename the support to A-FT09-1 by typing the new name in the Name field.

(26)

www.aveva.com

Select FT09and OK

The following form will then be displayed to the support designer.

The first element to be supported on the MDS framework must be a pipe, and it will become the datum atta.

This is an application term that is used to identify the first pipe added to the support.

Click the ‘Create datum support atta’ button and identify a pipe to be supported from the graphical view.

Identify Pipe /6"-A150-1002

(27)

www.aveva.com

Ancillary selection Progress is displayed on the bottom right of the main Graphical Screen.

On successfully identifying a suitable pipe, the Ancillary Selection form will be displayed as follows

The list of available ancillaries displayed in this form is controlled by: - • The available ancillaries for the project as listed in the catalogue. • The bore of the identified pipe in this case 150mm.

• The material code of the identified pipe is this case CS (Carbon Steel). • The insulation thickness in this case 0.

• The temperature of the pipe against the temperature range of the ancillary if set. • The elevation of the pipe against the minimum elevation of the ancillary if set.

5.3.1 List by Type

The List by Type Icons can be used to reduce the Ancillary Selection Set Anchors Ancillaries Guides U-Bolts Slip Units Stops Or All Select Ancillaries

(28)

www.aveva.com

Select XAT01 – Pipe show for N.B. 3/4” to 20 “

Select OK

The shoe will now be created at the previous component of the selected pipe or the pipe branch head, complete with a graphical tag of ‘Datum’

The datum atta will be created and named /A-FT09-1/DATUM, together with the associated support reference Atta, / A-FT09-1/SREF. This SREF atta is the link to the standard used and size of steelwork. The ‘Create datum support atta’ button is now deactivated as the datum atta has been created.

The shoe now needs to be correctly positioned along the length of pipe, by either entering a precise measurement and clicking the ‘Distance’ button, or by selecting one of the ‘Through’ positioning commands.

Select Through and ID Cursor

Identify the Steelwork above the support

(29)

www.aveva.com

5.4 Adding other elements to the support

The framework may now have more pipes, HVAC and/or Cable Tray elements added as required, by selecting an appropriate icon on the creation form. These are the first three icons in the option section of the form.

Any elements added will be automatically aligned with the ‘Datum Atta’.

Add a pipe adjacent to the datum atta already created by selecting the first icon and identifying the pipe. Select Add Pipe

Identify Pipe /6”-C150-1003

Select XAT06 – Clamp on pipe shoe for stainless or galvanised pipe

You will notice that the pipe material is Stainless Steel.

Select OK

The second atta will be created and named /A-FT09-1.1 in the selected pipe branch.

If any HVAC or Cable Trays are added to the support the support atta will be represented by a temporary ‘lollipop’ symbol

The HVAC and Rack (Cable Tray) supports are temporarily represented by the ‘lollipop’ symbol, because the fixings to the support steelwork are regarded as supplied by the HVAC and/or the Cable Tray contractor. When the support creation is completed the ‘lollipop’ symbol/s will disappear. These lollipop symbols do not have any clash properties.

(30)

www.aveva.com

Add Support ‘lollipop’ to both the HVAC and the Tray in a similar way to before using the correct icons..

5.5 Template Selection

Now that all of the ancillary supports have been created, the framework support steelwork size may be selected from the available list. This list will be displayed on the form as shown below when you select the ‘Choose Steelwork Template’ icon. The selection of the steelwork size is not mandatory at this stage and can be selected at any point.

For this exercise select the third option of 100x100x12 Angle, Internally

5.6 Support Creation

There are three methods of creating the MDS Framework; they are ‘Cursor’, ‘Clearance’ and ‘Dimensions’

5.6.1 Creation by Cursor

Create the support by selecting the Create by ‘Cursor’ option - Two steel sections can be identified for this support

The prompt ‘Identify element to support from’ will appear in the bottom left hand corner of the MDS Application main menu form.

(31)

www.aveva.com

First identify a steelwork section running parallel to, above and to the left of the datum support. Second identify a steelwork section running parallel to, above and to the right of the datum support.

Both shown below in Red.

The support framework will now be generated and the dimensions on the form will be calculated and their values updated on the framework creation form.

5.7 Add the Cross bar

If an element has been added to the support that is on a different level to the datum atta the forth icon ‘Add Cross Bar’ can be selected.

Select the atta of the pipe that requires a cross bar and then select the escape button to create the cross bar.

Select Add Cross Bar

In this case select the ‘lollipop’ on the HVAC and

Tray then <Escape>

Click on the OK button of the MDS Framework creation form to complete the support, and the Support Integrity Check form will be displayed as shown below.

(32)

www.aveva.com

5.8 Support Integrity Checker

The support integrity checker will run automatically every time a support is completed. It will run checks on the support and checks for the following.

• Maximum steelwork sizes.

• If the template is setup with maximum allowable section lengths that can be used. • Valid references to bedplates, guides, etc.

• Maximum packing distances.

• Are all the pipes supported on steelwork.

• Check the min/max dimensions of ancillaries are not exceeded. If there is nothing to inform the user, the form will not be displayed.

There are three levels of checks that are performed; these are errors, warnings and messages. Any warnings or messages that compromise the integrity of the support should be rectified in order for the support to be considered as complete. However the support designer has the option in this case to exit the support creation form and return at a later date to modify the support.

If any errors are detected then the OK button will be deactivated, and the support is considered to be incomplete. Therefore the support designer is forced to select the cancel button and return to the MDS Framework creation form to rectify the reported errors before being allowed to exit the creation form.

5.9 Adding a Packing Piece

A packing piece can be added to make up the difference in elevation of the bottom of the atta and the steelwork, if the selected atta cannot be modified in height.

To add a packer; click on the ‘Add Packer’ icon and the prompt ‘Identify the Support Atta’ to Add Packing Piece to’ appears in the bottom left hand corner of the main form.

(33)

www.aveva.com

Select Type A

Size 100x100x12 RSA

Clearance 100

Select Build Packing Piece

The packing piece will be build as shown

Clicking on the form OK button completes the Packing Piece, and then clicking on the MDS Framework form also completes the support.

Click the Integrity Check form OK button to complete the creation of the support or click the Cancel button and return to the MDS Framework creation form.

5.10 Creation by Clearance

The “create by clearance” option is where the user may identify only one element and the MDS application will work out the clearance needed. The clearance values between the vertical support sections of the support and the pipes being supported are obtained from the Pipe Clearance field in the MDS Application Defaults form.

If you have completed the support you will need to re-edit the support using the Modify Support Icon from the main Multi Discipline Support Toolbar

Support Name /A-FT09-1

OK

(34)

www.aveva.com

Select the Clearance option from the list of Framework Creation methods

Identify the SCTN above and running at right angles to the pipes etc. to be supported.

The application will now generate the support and calculate the dimensions of the support utilising the identified SCTN.

The clearance values between the vertical support sections of the support and the pipes being supported are obtained from the Pipe Clearance field in the MDS Application Defaults form

(35)

www.aveva.com

5.11 Creation by Dimensions

This method may be used to create the framework support when the structural steelwork may not yet be in the AVEVA Plant model enabling the pipe support designer to proceed with the creation of supports. The Support Designer may also wish to round up dimensions created using the “Clearance” Method.

By clicking the View… button a drawing of the current support type is displayed, showing the location of all of the dimensions etc. or you may use the show/hide framework dimensions icon to graphically display the required dimensions.

Show / Hide Framework DimensionsIcon

Enter the required dimensions into the MDS Framework form, e.g..

Dimension 1 = 1500

Dimension 2 = 500

Dimension 3 = 897

Dimension 4 = 897

Select the “create by dimensions” icon and the framework will be generated to the dimensions entered.

(36)

www.aveva.com

5.12 Changing steelwork size

Changing the size of the required steelwork section will regenerate the framework in the selected material size utilising the dimensions shown on the form, i.e. the support framework design will be automatically regenerated in the selected size of material as if the ‘Create by Dimensions’ option had been selected.

Select the Choose Steelwork Template Icon

Select a different Steel Size

152 x 89 Channel, Internally Bolted

Dismiss

L

For the purposes of the training the support steel should be 100 x 100 x 12 Angle.

5.13 Using Combinations of Create Methods

To create a support to the desired dimensions it is possible to use combinations of methods to achieve the required support.

(37)

www.aveva.com

5.14 Creation Options

The support may now be modified using the various icons available to the support designer. Any icons that are not required by the particular standard will be deactivated (greyed out).

The icons and options, which appear on each support type, is dependant on its usage and orientation, therefore not all icons and options appear on every support form or can be used in every orientation.

1. Choose Steelwork Template – This icon displays the template selection form and enables the support designer to change the steelwork size and/or configuration. If the support exists with the AVEVA Plant database the support will be regenerated using the dimensions stored on the main creation form.

2. Create by Cursor – This icon prompts the support designer to identify design elements in order to calculate the dimension required to generate the support. If the support exists with the AVEVA Plant database the support will be regenerated using the dimensions calculated and stored on the main creation form.

3. Create by Dimensions – This icon generate the support using the dimensions stored on the main creation form. If the support exists with the AVEVA Plant database the support will be regenerated using the dimensions stored in the main creation form.

4. Create by Clearance – This icon prompts the support designer to identify design elements in order to calculate the dimension required to generate the support. The clearance value used is stored on the MDS Application defaults form. The application will calculate the dimensions required by using the geometry of all the atta’s owned by the support. If the support exists with the AVEVA Plant database the support will be regenerated using the dimensions calculated and stored on the main creation form.

5. & 6. Reverse Dimensions – Using this icon modifies the dimensions stored in the form. If dimension 2 is offset i.e. not half of dimension 1 it will adjust the dimension to offset the support in the opposite direction. This will be only on supports that are appropriate. The two sketches

(38)

www.aveva.com

below show an example of what happens when an FT09 has dimensions 1, 2 reversed and dimensions 3, 4 reversed.

Dimensions 1 and 2 Reversed

Dimensions 3 and 4 Reversed

7. 8 and 9 Add Pipe/HVAC and Tray – This icon enables the support designer to identify a pipe, HVAC and tray element to be added to the support. If the support designer identifies a pipe then the application will scan through all the available standards and present to the support designer only those applicable to the identified pipe. The application uses the material of the pipe against the standard, the bore and insulation thickness as filters.

10. Add Cross Bar – For those supports that enable the creation of a cross bar the support designer is prompted to identify the atta already supported by the support to have an additional cross bar created.

11. Mirror Frame – This icon will mirror the framework perpendicular to the datum atta direction.

Before Mirror After Mirror

12. Rotate Frame – This icon will rotate the framework about the datum atta. The example being used XFT09 is not suitable for the rotate functionality so the examples below use XFT03.

(39)

www.aveva.com

Before Rotate After Rotate

13. Align Support – When the support designer is creating a support he may position the datum atta through a piece of steelwork but the exact position of the support along a piece of tube may not be calculable until the framework has been created. This functionality enables the support designer to select a position on the support using the EDG (Event Driven Graphics) facility and then another point anywhere in the design.

The application will then calculate the direction and position to move the support. In more cases than not the user will identify the element origin to use for repositioning, please make sure that the EDG selection is set to Element Snap in this case

Select Align Support

Select Element and Snap

Identify the Vertical Steel(1)

Identity The Supporting Steel(2)

(40)

www.aveva.com

The Pipe Support Steelwork will now be aligned with the Main Steel.

14. Modify Section – If the selected templates allows for the modification of an individual section the application will display the modify section start/end form from the Beams and Columns Application. The support designer will be presented with a message asking if they are sure they want to continue and modify the section. Any modifications completed with this icon will be overwritten when the support is regenerated by the application.

If you select Yes

You can use this form to Modify section sizes and positions etc.

15. Add Packer. - This enables the support designer to add packing pieces to support atta’s that are not sitting directly on the steelwork.

16. Delete Packer - This will enable the support designer to delete a packer already added to the support framework.

(41)

www.aveva.com

18. Rotate Atta – This enables an individual atta to be rotated. The align button can be used to align the

atta perpendicular to an identified surface.

19. Modify Datum Atta – This enables the support designer to declare another atta on the support to be used as the datum. This is only necessary when the datum atta is to be deleted from the support. When this is done the support may change in its position, this is because the datum position has now changed and the support will be regenerated using this datum.

20. Reference Bedplates – This can be used to reference the support to various connection items. If the item being referenced is located in a read only db, then a one way connection is made.

21. Associate Atta – When a pipe is added to a support via the atta created in the branch an associate is made between the first cross bar and the atta. This is used by the integrity checker to check if the atta is being supported and how far it is away from its supporting steelwork. When creating a cross bar the support designer identifies an atta, in some cases two atta’s are required to be associated with a secondary cross bar. If the support designer does not identify the second atta then the integrity checked will stop the support designer from exiting the support because it is to far away from the first cross bar. This is used to associate any atta that is not identified on the initial creation of a cross bar. 22. View Associations – This will colour code the graphical display so that the support designer can view

the current associations to check that they have been defined correctly. When the support designer first initialises this functionality the first cross bar and its associated atta’s are coloured. The support designer then can select another cross bar with the cursor and its associated atta’s will be coloured. The support designer enters escape to exit.

23. Flip Field Weld – When a field weld is required on one end of a section, for example XFT07 a post, the application selects the longest section from the centreline of the pipe to the end of the section. In some cases this field weld is required at the other end; in this case this icon can be used to move the field weld. This has been superseded by the new welding functionality.

24. Modify Atta – The support designer will be asked to select which atta they want to modify if more than one exists and the following form is displayed.

If the selected ancillary has any modifiable properties then the support designer will be able to modify them with the range displayed on the form. As can be seen the above example is displaying the height and length

(42)

www.aveva.com

as modifiable properties. Both of these values may be manually changed, but only within the maximum and minimum limits.

1. Clicking on the ‘Set Parameters to Default’ button will set the ‘Height’ and ‘Length’ values to their default values.

2. The ‘Set Height to Steel/Bedplate’ button is a graphical method of defining the ‘Height’ value of the support, but only within the maximum and minimum values described above.

3. Clicking on the ‘Modify Ancillary Type…’ button will display the same ‘Ancillary Selection’ form used when the atta was first selected.

The ancillary type may now be reselected from the available list as required. Click the OK button to change the ancillary type or click the Cancel button to maintain the existing ancillary type and dimensions.

4. Modify Ancillary

Used to change the Ancillary settings

25. Delete Atta – This enables the support designer to identify an atta to delete from the support. This will also rename the support atta’s that are left in the correct order.

26. Nudge Support – This enable the support designer to nudge the whole support including all atta’s a specified distance either upstream or downstream of the datum support.

(43)

www.aveva.com

27. Spooling – This enables the support designer to spool the steelwork for erection purposes. The spool

number is depicted on the MDS drawing along side the part number. I.e. 5(2) designates part number 5 belongs to spool 2.

28. Set Section Material – When the support designer first creates the framework if the material of each section is set in the template it will be copied to the support. This enables the support designer to reselect the material for the support within the design database.

29. Copy Like – This enables the support designer to identify a support of the same type and the dimension used for the identified support will be copied to the new support.

30. View Standard – This will display the standards plot file.

31. Create Connections - The framework connectivity can be maintained to the main steelwork by the addition of joints. After the framework has been positioned correctly select the ‘create connections’ button on the support form and the necessary nodes will be created automatically. The support designer will then be presented with the modify joints form where they can select the required joints and settings.

L

Name sure you have aligned the steelwork as describe above before attempting and connections.

(44)

www.aveva.com

Select Apply to All Joints

Select /Bent_Clamp_Plate_Joint

Select ApplyandDismiss

L

Note that a secondary node will have been created so the Support Designer will need access to the Supporting Steelwork.

32. Modify Connections – If the connections to the main steelwork exist then the joint specification form will be displayed with the current joint type selected.

Select Modify Connections

Select Joint 2

Select BeamFLanges_twin_Clamp_Plant_Joint

Select ApplyandDismiss

You can see that Joint 2 is now showing a Beam Support.

33. Delete Connections - The framework connectivity can be removed by deleting the existing joints. 34. Force Connections – In some circumstances the pline found to use, as the connected pline is

(45)

www.aveva.com

the intersection of the centreline and web edge of an I section. If this is the case the support designer can identify the pline required with the cursor. This will happen infrequently.

35. Show/Hide Framework Dimensions – This will graphically display a set of dimension required by the selected standard. If no dimensions are set on the form it will use a default set of dimensions. These are useful when a support designer is new to the application.

36. Centre on Support – This will centre the support datum atta to the centre of the graphical view but will not change the scale.

37. ADP Drawlist – This icon enables the support designer to add elements to the MDS drawing. Each drawing will contain the structural steel, all pipes and any connected steel by default. This extra draw list may be used to add items of interest to the drawing.

38. Modify ADP Location Position – When a location plan is created on the MDS drawing the origin of the datum atta is used to locate the support to the nearest columns. This position may be modified to any point in the design database by using the EDG (Event Driven Graphics) sub system.

(46)

www.aveva.com

39. Trimmer Required – This sets a logical flag at the support structure element to record the fact that a

trimmer is required to be added to the main structural steel. A report is provided that will list all supports requiring trimmer steel to be added. If the support is connected to steelwork the support designer will not be allowed to set the trimmer required flag.

40. Set Ancillary Material – This enables the support designer to set the material of the ancillaries. By default the material is set when the support designer creates the ancillary and would not be normally modified.

41. Copy Ancillary – This enables the support designer to copy an existing ancillary, the new ancillary will be created in the same branch. It will be rotated by 90 degrees.

42. Nudge Ancillaries – This enables the support designer to nudge one or more ancillaries independent of the supporting structure.

43. Set Trunnion Length – This will only be active for the trunnion standards. This enables the support designer to select a design element to calculate the trunnion length required. It will check that the calculated length does not exceed the minimum or maximum values for the standards being created. 44. Set Trunnion Material – This will only be active for the trunnion standards. This will scan the current

MDB for a specification that has a purpose attribute set to TRUN. If it finds one it will only display the material stored in this specification, if not it will scan all specifications for tube material. The parent pipe material will be indicated on the selection form.

(47)

www.aveva.com

45. Add Notes – This enables the support designer to add notes to the MDS drawing, the support

designer selects the member of the support they require to add a note to. They then complete the text required. By default it will use the origin of the selected member to point the leader line to. The support designer may modify this origin position.

53. Repeat Atta – MDS allows you to repeat a support from one line (pipe) to another. This is possible for standalone ancillaries and support frames only; the repeat function is not available for trunnions and hangers. (Note this differs from the Copying a Support function). Two repeat functions are available: one is used for repeating a standalone ancillary, the other for repeating a support frame.

54. Trim Section End to Surface – used when the support section intersects with a sloping surface particularly useful when a Support goes onto a sloping panel.

5.15 Finishing the support creation

After changing the pipe support design by using any of the icon buttons shown on the MDS Framework form, click on the OK button to display the Support Integrity Checker form, and if the support design is acceptable, click on the OK button to complete the support.

The Support Integrity Check form may display Errors, Warnings and Messages.

5.15.1 Errors

• Checks to see if the maximum packing distance has been exceeded, as per the maximum packing distance value on the Application Default form.

• Checks to see if any of the support attachments are NOT positioned along the length of the associated cross bar.

• Checks to see if any of the dimensions values associated with the support ancillaries i.e. shoes. Do not exceed the values defined in the default file (DES-SUPP-PARS) in the Project Default directory.

• Checks to see if any reference used within the MDS application, i.e. Bedplate reference no longer exists.

5.15.2 Warnings

Maximum length of steelwork is not to be exceeded. In the design template database each SCTN member has an allowable maximum length, which should not be exceeded.

5.15.3 Messages

These are issued for information purpose only

If nothing is found to display to the user the form will not be displayed.

5.16 Summary of the Creation of a Multi Discipline Support

The basic workflow of every framework support is very similar and follows the workflow below. • Select standard support type from menu or icons.

• Enter name of support.

• Create datum attachment and select ancillary type. • Set distance/position of datum attachment.

• Add other Pipe(s) etc. to be supported • Choose steelwork size from available list. • Create by the required creation method. • Add Cross Bar(s) for other Pipes etc. • Use any miscellaneous option required.

• Select packing if required or Modify the Atta/Ancillary support • Select OK and check the Support Integrity Checker.

CHAPTER 6

6 Modification of a Support

This chapter explains how to modify a support

6.1 Modifying a support

To modify a support either select the icon from the toolbar or select the option Modify>Support... from the MDS Application main menu.

(54)

www.aveva.com

6.1.1 Methods of selecting the support to be Modified

There are three methods of selecting the support to be modified. 1. Typing the Support Name directly into the name text gadget.

2. Clicking on the ‘Identify By Cursor’ button will request the support designer to ‘Identify the support to modify’ from the graphical display, and automatically add the Support Name to the text gadget. 3. Clicking on the ‘CE’ button will automatically add the Support Name to the text gadget, as long as

the current element is a support.

When a valid support name has been entered into the Modify Support form, click on the ‘Apply’ button. This will display the same form as used to create the support, with all the option and text gadgets (Dimensions etc.) correctly displayed on the form to reflect the current support design

The principle of using the same form for Creating and Modifying a Support is generally applied throughout the MDS Application.

The methodology of modifying a support follows the same principles as when a support is created.

Any changes made to the support via the modification form may be discarded by clicking the ‘Cancel’ button, and the support will be regenerated to its original configuration, dimensions and size etc. as when the modification process was first initiated.

If during the modification process a support ATTA, pipe shoe etc., is deleted from the support (icon number 25), the ‘Cancel’ button on the modification form will be deactivated, and the regeneration of the support to its original design will NOT be possible. Warning messages, shown below, are issued to the screen for the support designer to Confirm if the ATTA deletion is required. If the ‘YES’ button is clicked on BOTH forms, then the support ATTA will be deleted and the ‘Cancel’ button deactivated.

First ‘Confirm’ Warning Message

Second ‘Confirm’ Warning Message (Modify mode only)

The process to modifying a support is the same as the creation, where all available options can be used to modify the support.

L

Note! It is imperative that users do not delete support elements from the command line. Any support element that is deleted will corrupt the support and cause the application to fail.

Exercise 3 – Modifying a Support

CHAPTER 7

7 Deleting a Support

This chapter explains how to delete a support

7.1 Deleting a Support

To delete a support either select the icon from the toolbar or select the option Delete>Support... from the MDS Application main menu.

The Delete Support form will be displayed as shown below.

7.2 Methods of selecting the support to be Deleted

There are three methods of selecting the support to be deleted. 1. Typing the Support Name directly into the name text gadget.

2. Clicking on the ‘Identify By Cursor’ button will request the support designer to ‘Identify the support to modify’ from the graphical display, and automatically add the Support Name to the text gadget. 3. Clicking on the ‘CE’ button will automatically add the Support Name to the text gadget, as long as

the current element is a support.

When a valid support name has been entered into the Delete Support form, click on the ‘Apply’ button. This will display the ‘Confirm’ Warning Message shown below. Either click the ‘YES’ button to delete the support or the ‘NO’ button NOT to delete the support.

(56)

www.aveva.com

7.3 Error trying to delete Supports using normal delete method

If the support designer tries to use the standard delete menu an error message will be issued if a support is found.

If a support has an associated support for example if you delete a shoe that has an associated guide, the application will prompt the user to inform that the guide will be deleted as well. The user is given the option to cancel the operation.

L

Note! It is vital that a user does not delete a component of a support from the command line, this will cause the corruption of the support and MDS may not be able to recognise the support.

CHAPTER 8

8 Locking a Support

This chapter explains how to lock a support

8.1 Locking and Unlocking a Support

To lock a support either select the icon from the toolbar or select the option Modify>Lock/Unlock Support... from the MDS Application main menu.

(58)

www.aveva.com

There are three methods of selecting the support to be locked/unlocked.

1. Typing the Support Name directly into the name text gadget

2. Clicking on the ‘Identify By Cursor’ button will request the support designer to ‘Identify the support to modify’ from the graphical display, and automatically add the Support Name to the text gadget. 3. Clicking on the ‘CE’ button will automatically add the Support Name to the text gadget, as long as

the current element is a support.

When a valid support name has been entered into the Lock/Unlock Support form, click on the ‘Apply’ button.

8.2 Locking a support
