MDS User Guide

Introduction

12.01:1

1 Introduction

1.1 About this User Guide

This document provides guidance to the design engineer on how to create supports using

the Multi Discipline Supports (MDS) application. It is assumed that the design engineer has

a basic understanding of the application.

1.2 Overview of the MDS Applicat ion

The MDS application allows you to create supports for piping, cable racks, and HVAC. It is

highly interactive, enabling you to design supports with the minimum of effort. The MDS

application is also highly configurable, allowing the administrator to define project-related

defaults, to control the design of supports, and to determine the range and types of ancillary

components that can be used on a project.

The standard framework supports in the MDS application are designed using structural

sections and are template driven. A default set of structural templates based on British

Standard steelwork sections is supplied with the MDS application. Any relevant nationalstandard for steelwork sections can be used by configuring the supplied templates. For

further information refer to the Customisation Guide.

If the templates supplied do not suit your project or company requirements, get your MDS

administrator to configure them, or contact AVEVA Solutions to investigate your

requirements or create a special. The requirement to add an extra member to an existing

template configuration is an example of a special. The support would be designed as, or

converted to, a special and then the extra member added to the special structure with the

standard Beams and Columns application.

Ancillaries are elements, such as u-bolts, bolt-on shoes, anchors, or slip-units, which are

attached to pipes. Ancillaries associated with the template are those suitable for, or

available with the standard.

Ancillaries for cable trays and HVAC, sometimes referred to as fixings, are deemed to be the

responsibility of the relevant contractor and are not dealt with in this application.

The creation of every support follows this process:

1. Select a support type from a menu or icons.

2. Enter a name for the support.

3. Create a datum atta (attachment point element) and select an ancillary type.

4. Set distance and/or position for the datum atta.

5. Choose the steelwork from a list of available sizes.

6. Create using the required creation method.

7. Select miscellaneous options.



12.01:2

Introduction

8. Select the packing if required.

9. Complete the process (the Integrity Checker runs automatically at this point).

10. Run the MDS Health Check Utility, which performs a comprehensive check for theexistence of any problems.

1.3 Administrator ’s Role

The administrator is responsible for the initial setup of the MDS defaults in the DATASETS

stored in the PARAGON database, the default files and the DESIGN template database

associated with the MDS application.

1.4 MDS Catalogues and Specif ications

The MDS application is supplied with a catalogue and specifications. The range of bores

and components in the catalogue are fixed.

The /MDS specification contains all ancillary types, and the /MDF specification contains the

SREF attachments for standard frameworks.

The /MDP specification contains the preliminary support type available within the MDS

application.

The /RPAD-MDS-PLATE-MATERIAL specification contains the material used for

reinforcing pad type supports.

Note: The catalogue and associated specifications must NOT be modified.

2 Using the MDS Application

2.1 Starting the Application

1. Start the DESIGN General Application (default start-up). The DESIGN General Application start-up form (Figure 2:1.: General Application form) is displayed.

Figure 2:1. General Application form

2. Select Design>Multi Discipline Supports… from the main menu (Figure 2:2.: Designpull-down menu).



12.02:2

MDS User Guide


Figure 2:2. Design pull-down menu

The start-up form re-initialises to become the MDS startup display (Figure 2:3.: MDSstartup display), which includes all functions specific to the MDS application.

The system tests for the existence of the design template database /MDS/TEMPLATES and the /MDS and /MDF specifications. If neither of these exists, MDSentry is stopped, an error message is displayed, and you re-enter the DESIGN General Application. If this occurs, ask your administrator to add the owning databases to your MDB (Multiple Database).



MDS User Guide


12.02:3

Figure 2:3. MDS startup display

Simultaneously, the application overlays a form (Figure 2:4.: Default Creation Zoneform) listing all valid zones found in the current MDB. The administrator controls theselection of which zones are displayed. For more information on how these zones areselected, refer to the MDS Admin Data form section in the MDS Administrator Guide.

Figure 2:4. Default Creation Zone form

3. Select a zone in which to create your support structures and click OK. Two tool bars(Figure 2:5.: General Setup and Shortcut Toolbars) are, by default, located under the

main menu bar.



12.02:4

MDS User Guide


Icons which control the general setup and display operations are, by default positionedon the left.

The icons to the right of centre are short cuts to all the available menus in the MDS

application. Place the cursor over each of these icons to display an associated tool tip.

Note: Toolbars conform to standard Windows operation and can be repositioned in a

number of ways. Beware that some icons may be hidden if you re-arrange the

toolbars. The hidden icons on any toolbar can be accessed using the drop-down

arrow at the right-hand end of the toolbar.

Figure 2:5. General Setup and Shortcut Toolbars

Each icon and its assigned action or purpose is listed in the following table:

2. Ensure that the pipes, cable rack or HVAC you need to support are added to theDrawlist, along with any other elements needed to create the support. This may includesteelwork and panels, depending on the creation mode that is to be used. They mustbe added to the graphical view to be identified.

3. Create the datum atta. This is the attachment on the first pipe that is associated withthe support structure. This must be a pipe, not a cable rack or HVAC element.

To create the datum atta select the Create datum support atta button at the top of theform. You are presented with the cursor so that you can identify a pipe. When you havedone this, the Ancillary Selection form containing a filtered list of all the availableancillaries at the selected pipe bore, is displayed (Figure 2:13.: Ancillary Selectionform). These may be restricted for each framework type. For more information refer to

the MDS Administrator Guide.

Note: The HVAC and cable rack support attachments have a ‘lollipop’ representation. This

is because the fixings to the steelwork are regarded as supplied by the HVAC and

cable rack contractor; no allowance is made for the selection of different fixings in the

MDS application. The ‘lollipop’ representation is removed when the support is

completed, returning to its original drawing level before the support was created.

There are no obstruction properties associated with the lollipop representation and

no clashes are reported.

2.5 Creating and Manipulating Connections to External

Steelwork

After the structural steelwork has been created, it may be necessary to connect it to external

steelwork.

To add a connection to external steelwork:

• Select the Create Connections icon . This creates a connection only if the

application knows the identity of the steelwork to connect to.



12.02:20

MDS User Guide


If you used the Create by Cursor or Create by Clearance methods the connection to the

external steelwork is made automatically.

Note: It is essential that you have write access to create SNOD/SJOI elements on the

necessary external steelwork.

The SNOD is represented in the graphical view. The MDS application defaults control the

level at which joists can be made to the external steelwork.

Refer to the MDS Administrator Guide for more details.

1. Select the Modify Connection icon . You are presented with a form that displays allthe available joints.

2. Select the joint for the joints connected to the external steelwork.

If you have identified the external steelwork to connect to with either Create by Cursor or Create by Clearance, it is possible that the application will connect to the wrongPline. This can happen in the case of the SCTN having floating Plines (X) ((a) in Figure

2:22.: Forced connection to SCTN with floating Plines).

Figure 2:22. Forced connection to SCTN with floating Plines

You can force-connect the joint to a specific Pline ((b) in Figure 2:22.: Forced

connection to SCTN with floating Plines) by selecting the Force Connect icon . You

are prompted to identify the required Pline using the cursor.

To delete a connection:

1. Identify the connection with the cursor.

2. Select the Delete Connections icon.

2.6 MDS Structural Associations

This MDS Structural Associations utility is entirely dependent on the existence of the

standard AVEVA Associations database MASTER/ASSOCDEFN in the current MDB being

used by the MDS design application.

The database MASTER/ASSOCDEFN is required to be included into the current project,

preferably as a FOREIGN database, from the standard AVEVA MAS project, i.e. filename

/%MAS000%/mas7027.



MDS User Guide


12.02:21

The standard AVEVA Associations Manager form also interfaces with the MDS Structural

Associations utility.

The MDS Structural Associations are generated either automatically or manually, depending

on the mode of creation/modification of the MDS support.

2.6.1 Automatically Generated MDS Structural Associations

The MDS Structural Associations are created automatically during the creation/modification

of a MDS standard framework support structure, when the creation mode used is Cursor

or Clearance , and the user graphically identifies the main structural element(s)

from which the MDS structure SCTN element(s) will be supported.

The figure below shows a typical MDS support created by Cursor :

Figure 2:23. MDS Support created by cursor

The MDS Structural Associations are automatically generated for the MDS support, shown

in the picture above, in a ASSOWL element created automatically and named to reflect the

SITE name where the MDS supports are being created, i.e. the ASSOWL name will follow

the convention <sitename>-MDS-ASSOWL.

The figure below shows the typical hierarchy of the MDS supports ZONE and their structural

associations ASSOWL:



12.02:22

MDS User Guide


Figure 2:24. Typical MDS hierarchy

A similar hierarchy to one shown above would also exist for the automatically generated

associations when creating the MDS Support by Clearance



MDS User Guide


12.02:23

2.6.2 Manually Generated MDS Structural Associations

The MDS Structural Associations will not be created automatically during the creation/

modification of a MDS standard framework support structure, when the creation mode used

is by Dimensions .

When a MDS support is created by Dimensions , any existing MDS Structural

Associations (ASSOC elements) for the MDS support will be deleted, but the owning

Association Group, ASSOGP element for the MDS support will remain.

The MDS Structural Associations may now be manually generated by selecting the main

menu bar option Create>MDS SCTN Association , i.e.


It is important to note that a manually generated MDS Structural Association may be created

at any time for an existing MDS framework support, and is independent of any form used for

the creation and/or modification of a MDS framework type support.

After selecting the MDS SCTN Association option a prompt will be displayed in the status

bar, to 'Identify a MDS Support SCTN element to Associate', e.g.



12.02:24

MDS User Guide


Figure 2:26. Identify a MDS support SCTN element

The user must first identify a MDS Support SCTN element as prompted and then the user

will be prompted to 'Identify a MAIN Structure element to Associate with the MDS SCTN

element', e.g.

Figure 2:27. Identify a main structural element

When the two vertical MDS SCTNS have been associated with the relevant MAIN structural

elements, the Association Group (ASSOGP) hierarchy for the MDS support will be

populated with the Association (ASSOC) elements etc…, as shown in the figure below:



MDS User Guide


12.02:25

Figure 2:28. Association Group hierarchy

2.6.3 AVEVA Associations Manager Form

The standard AVEVA Associations Manager form is displayed by selecting the main menubar option Utilities>Associations>Associations …, i.e.

Figure 2:29. Utilities menu

The standard AVEVA Associations Manager form is shown below:



12.02:26

MDS User Guide


Figure 2:30. Association Manager form

The Association Fil ter - Show option gadget has been changed to 'Current Element' and

the Purpose option gadget has been changed to 'MDS'.

Clicking the Refresh button has populated the Associations grid with the associations for

the current MDS framework support structure.

Clicking the left hand side of an association will automatically populate the other two lower

grids, Restrictions and Associations Detail with the data of the selected Association.

When the cursor is placed over a highlighted association other options are made available

by clicking the right mouse button. The options are self explanatory.

Users should familiarise themselves with the standard AVEVA Associations form, described

in Getting Started with PDMS/OUTFITTING.

Note: The standard AVEVA Associations form is a general utility, which is available for use

by the other discipline design applications in the AVEVA MARINE/PLANT software,

as well the MDS design application.

2.7 Ending the Creation of a Support

When you have finished the support, click on the OK button.

The application then performs a series of integrity checks to ensure that the support is

completed. If any errors are found the OK button is deactivated and the support is not

completed until you have rectified the errors. The checks performed are as follows:



MDS User Guide


12.02:27

- Displays a message

• If the packing distance is greater than 2mm but not greater than allowable packingdistance.

• If the support is a special, a message is issued to you to create the structural steelwork.

• If no warning or errors are found.

- Disp lays a warning message

• If the maximum length of steelwork is not to be exceeded. In the design templatedatabase each member can be given a maximum length that it may not exceed.

- Disp lays an er ro r message

• If the Application Default maximum packing distance has been exceeded.

• If any of the support attachments overlap the crossbar. A maximum overlap value is seton the MDS Application Defaults form (see Viewing the Application Defaults).

• If any of the dimensions associated with the support ancillaries, for example shoes,exceed the values defined in the MDS Ancillary Defaults form (refer to MDS

Administrator Guide).

• If any reference used within the MDS application, for example bedplate reference, nolonger exists.

2.8 Modifying a Support

You can now modify the support using the various options available on the MDS XFT09

support form (Figure 2:12.: XFT09 - MDS framework form). A description of each option,

along with its associated icon, is shown in the following table. The access to each icon is

dependent on the configuration being used. Icons for unavailable options are greyed out.

Mirror framework mirrors the support, perpendicular to the datum

attachment, repositioning the framework members through the structure

origin.

Al ign suppor t picks two points with the EDG (Event Driven Graphics)

application. It then calculates the distance between the two points, using the

datum attas leave direction. This allows you to position the support more

accurately.

Modify support section modifies a section belonging to the support with

the standard modify section start/end form. If a section is modified using thisfacility, any future regeneration of the support will not include these

modifications and returns to the default configuration.

Add packer adds packing pieces to support attas that are not sitting directly

on the steelwork.

Delete packer deletes packing pieces already added to the support

framework.

Rotate all attas can be used when the support type is used with vertical

pipes. It rotates all the attachments by the angle entered into the text field

next to the icon.



12.02:28

MDS User Guide


Rotate atta rotates individual attas. It rotates the attachment by the angle

entered into the text field next to the icon.

Modify datum atta modifies the datum atta from one atta to another.

Bedplate reference associates a support steelwork member with a

bedplate. This information is then added to the subsequent drawing, which

can be created with the MDS Automatic Drawing Production application.

Associate atta associates an attachment with a crossbar. It allows you to

associate an attachment at any time.

View associations shows the support attachments that are associated with

each crossbar. This can be very useful if the support Integrity Checker

identifies a large packing distance between the support attachment and the

associated crossbar. Often the reason for this is that the attachment is

associated with the wrong crossbar.Modify atta modifies the ancillary type or certain dimensions of the support

attachment.

Delete atta deletes an attachment from the support framework. The datum

attachment cannot be deleted from the support.

Nudge nudges the support with the flow or against the flow, depending on

which icon is pressed, by the distance value entered in the text field next to

the icons.

Spooling creates spools for the steelwork erection procedure. The MDS

ADP drawing displays which spool the steelwork section belongs to in the

material list.Set materials of the steelwork sections.

Copy like identifies another support of the same standard and copies its

dimensions. The number of associated pipes, cable trays, and HVAC

elements do not have to be the same on each support.

View standard displays the standards associated plot file.

Create connections section to existing main steel.

Modify connection to existing steel.

Force-connect to existing main steel.

Disconnect template sections from existing main steel.

Show/hide framework dimensions graphically displays the dimension of

the support standard.

Centre on support refreshes the graphical view with the support being

created or modified in the centre. The view scale is not modified.

representation and material list for individual ancillaries/support framework.

Create weld lets you view, create, modify, or delete welding information.

The icons described below are available on other support standards.

Rotate frame rotates the framework about the datum attachment.

Flip field weld is used when a support type can be built with the field weld

at either end of the framework steelwork member. It will place the field weld

at the other end of the steel and depict it with a textural aid.

Identify steel for calculation of trunnion lengths.

2.11 Repeating a Support

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.

2.11.1 Repeat a Standalone Ancillary

To repeat a standalone ancillary:1. Select Create>Repeat MDS Ancillary Support from the main menu.

A prompt is displayed at the bottom of the main window: ‘Identify MDS Ancillary toRepeat’.

2. Click on the ancillary that you want to repeat. Any atta that has been created by theMDS application can be selected, even if it is a member of a support frame, exceptHVAC and cable rack supports. After selection the atta is validated, and if it does notmatch the conditions above, you are prompted to select another atta until you pick onethat does meet with conditions.

After the atta has been validated, a prompt is displayed at the bottom of the mainwindow: Identify tube of pipe to Add Ancillary.

3. Click on the piece of tube of any pipe where you want to create a copy of the source

atta. When the atta is created, MDS performs the checks that are made when creatingan ancillary, to ensure that it is suitable for the selected tube (material, insulation,temperature and elevation).

If the selected tube cannot accept the new atta, an error message is displayed and theatta is deleted. Otherwise, the following form is displayed where a name can be givento the new atta:

Figure 2:34. Modify Support Name form

4. Type a name in to the Change to Support Name text field, or click on the MDS Au toname button to generate the name automatically. If you click on the Cancelbutton, the name displayed in the Existing Support Name field (ProvisionalName<n>

is assigned by default.

2.11.2 Repeat Support Frame

To repeat a support frame:

1. Select Create>Repeat MDS Framework Support from the main menu.

A prompt is displayed at the bottom of the main window: ‘Identify MDS Support Frameto Repeat’.

2. Click on the support frame that is to be repeated. Any member of a frame that has beencreated by the MDS application can be selected (atta, section, joints, etc). After selection the support frame is validated, and if it is not suitable (see ‘Limitations’ below,you are prompted to select another support frame until you pick one that does meet the

conditions.

Note that frames for HVAC and cable racks can be selected.

After the support frame has been validated, a prompt is displayed at the bottom of themain window: ‘Identify tube of pipe to Add Datum Atta of the Support Frame’.

3. Click on the piece of tube (or HVAC/tray section) where you want to create a copy of the source frame. Only the datum atta and SREF atta are copied; any other attas andadditional crossbars are not copied.

When the new frame is created, MDS performs the checks that are made whencreating a support, to ensure it is suitable for the selected tube/HVAC/tray section(bore, steelwork size, orientation).

If the selected tube, etc cannot accept the new support frame, an error message isdisplayed and the frame is deleted. Otherwise, the Modify Support Name form is

displayed so that you can give a name to the new frame. This is the same form that isdisplayed when repeating a standalone ancillary.

4. Type a name for the new frame, or use the MDS Autoname button, then click on OK.Click on Cancel to use the default name.

5. The repeat function works in a loop: each time a new frame is created you are asked toidentify another tube/HVAC/tray section for which a support frame is required.

To exit the procedure, press the Esc key on the keyboard.

2.15 Automatic Steelwork Orientation

MDS can automatically orientate the support structure steel members of a framework type

support, dependant on the orientation of identified stiffeners. This function is available when

you create a framework using the Create by Cursor method within the framework creation

process. A typical example of a support frame (FT08) is shown in Figure 2:37.: Example of

Steelwork Orientation.



12.02:36

MDS User Guide


Figure 2:37. Example of Steelwork Orientation

The correct orientation is achieved by utilising appropriate templates. Each standard

template has four alternatives as depicted above. The names of the alternative templates

are followed by a suffix, which is a configuration code based on the orientation of the

stiffeners as depicted. Only templates that are built up from angle profiles have oriented

alternatives.

The MDS Template Catalogue has left and right hand versions of a template. The left hand

version is used when the orientation of the stiffeners is found to be pointing in the same

direction as port, and the right hand version is used for starboard.

To use this feature proceed as follows:

1. On the MDS Framework form. click on the Create by Cursor icon . A prompt isdisplayed at the bottom of the main window asking you to identify the first stiffener, thenthe second stiffener.

2. Identify the stiffeners by clicking on them. MDS then checks that their gtype is angle. If so, the orientation of the stiffener is stored as a number in user-defined attribute (uda):MdsTmplOri at STRU level. The system then checks for the existence of an orientedtemplate with this number; if found, this is used instead of the standard template.

Note: Subsequent modifications of the support by the clearance/dimensions method will

always try to select the oriented template first.

All settings (number of bars, min/max bore, etc) are always obtained from the

standard template, except the value stored in uda :MDSBuildStyl, that is copied

from the alternative.

and a special support number. This special support number can be unique to one support,

or it may be used on several supports. This is controlled via the MDS Admin Data form. For

details, refer to the MDS Administrator Guide.

A prefix is used to identify a special support and is also controlled by the same default file.

The special support type can be:

• Multi Discipline

• Cable racking

• HVAC

To create a special support:

1. Select the Special Support icon from the tool bar, or select Create>Special... from themain menu. The Special Support form (Figure 2:41.: Special Support form) isdisplayed.

Adding Snipes to Steelwork Members

12.03:1

3 Adding Snipes to Steelwork Members

3.1 Description of Snipe Ut il ity

MDS provides the ability to create and modify snipes on support structural members. A

snipe is where a support structural member is cut at an angle, such that a corner is

removed. For example, Figure 3:1.: Snipes added to FT08 framework shows snipes addedto an FT08 framework type.

Figure 3:1. Snipes added to FT08 framework

This feature currently only works with angular sections, i.e. steelwork profiles of type SCTN

and gtype ANG. Two cases are catered for:

• Snipe on end of leg attached to stiffener

• Snipe on free end of section.

3.1.1 Snipe on End of Leg Attached to Stiffener

When the section is attached to a stiffener the following calculations are used, where

SL = Snipe length on the leg of the framework

FL = Length of leg section

M1 = Control gap for back-to-back (default = 10 mm)

M2 = Length in the opposite direction of M1 on flange of stiffener

M3 = Distance between flange top outside edge of stiffener and leg point

connected with the flange top of stiffener (default = 25 mm)



12.03:2

MDS User Guide

When L > M1 + FL + M2 and M2 >= 25mm,

Snip is not provided on support leg as below.

When L > M1 + FL + M2 and M2 < 25mm

Snip is to be provided on support leg as below

When L =< M1 + FL and M2 (=M1 + FL - L) =< 0 (zero) mmSnip is to be provided on support leg as below



MDS User Guide


12.03:3

3.1.2 Snipe on Free End of Section

When the section is not attached to a stiffener the following calculation is used:

Figure 3:3. Snipe on free end of section

3.2 Applicable MDS Templates

The snipes described in Snipe on Free End of Section have been added to angle sections of

all templates in databases MDS/DESITMPL-DIN and MDS/DESITMPL-DIN-ORI. The list of

modified templates is as follows:

3.3 Creating Snipes

Snipes can either be created automatically when an MDS framework is created or modified,or they can be created manually using the Snipes utility.

3.3.1 Automatically Created Snipes

If the support leg is attached to a stiffener and their configuration conforms to Figure 3:2.:

Snipe on end of leg attached to stiffener , snipes are automatically created when an MDS

framework is created or modified (using the MDS Framework form).

The snipe size is automatically calculated as follows:

• When the calculated size is less than the minimum allowable, the snipe is not created.The minimum snipe is set at 10mm and cannot be changed.

• If the calculated size is greater than the maximum, then the maximum size is used

instead. The maximum size depends on the angle section size and is calculated as the

FT03 FT11 FT34A

FT04 FT18 FT34B

FT05 FT19 FT36

FT06 FT21 FT37

FT07 FT29 FT38

FT08 FT31 FT39

FT09 FT32 FT40

FT10 FT33 FT42



12.03:4

MDS User Guide


difference between the size of the angle leg where the snipe is intended/created andthe thickness of the angle leg.

If the support leg is already connected by a joint to the stiffener, then the snipe is not

created, whereas the connection by joint is not allowed by the application if the snipealready exists.

Snipes created in this way can be modified or deleted by the Snipes utility (described

below).

3.3.2 Manual ly Created Snipes

To create/modify snipes manually, proceed as follows:

1. Select Modify>Add Snipes to Angle... from the main menu. The following form isdisplayed:

Figure 3:4. Snipes form

2. Identify the section which is to have a snipe added in one of the following ways:

• Type a name into the Modify Section text field.

• Click the CE button to modify the current element, if it is an angle section.

3. Use the Select Angle Leg option buttons to select the required leg of the anglesection.

4. Make the required selection using the Select Sniped End option buttons.

If the Identify by Cursor icon is activated, then the sniped end of the angle sectioncan be picked directly from the 3D graphical view. If the Au to function is enabled, the

snipe is created immediately after picking, to speed up the process.5. Enter values into the Snipe Length and Snipe Height fields. If the Lock/Unlock icon

is activated, the two values are locked together, and changing one changes theother.

The values are checked when entered. If a value is less than the minimum (fixed at10mm) then it is reset to the minimum. If it is greater than the maximum, it is reset tothe maximum size. The maximum size depends on the angle section size and iscalculated using the difference between the size of the angle leg where the snipe isintended/created and the thickness of the angle leg.

6. Click the Create button to confirm creation of the snipe.

7. Repeat the above steps to create further snipes. Click Dismiss to terminate snipecreation.

5 Hangers

The standard MDS application for hangers allows you to create fixed and variable pipe

hangers. The application is interactive and configurable, and simplifies:

• Definition of project related defaults.

• Control of hanger design.• Determination of range, types, and configuration of hanger components that can be

used on the project.

Hangers are designed using the hanger components catalogue of a given supplier and are

template-driven.

Note: The standard hanger templates are stored in a SITE named /MDS/HANGERS. To

use the standard hanger templates the default option property for the MDSHANGIF

keyword must be set to ‘Standard MDS’ on the PARAGON defaults database, (refer

to the MDS Admin Data form in the Administrator Guide).

The application is supplied with hanger templates from three different hanger component

suppliers. The project administrator can configure and customize those templates to adopt

any company’s hanger configurations or any other hanger components catalogue. For further information refer to the MDS Hanger Data form in the MDS Administrator Guide.

5.1 Creating a Hanger

There are two ways to access the hanger forms:

1. Click on the Fixed Hanger icon or Variable Hanger icon from the tool bar,

or …

2. Select the appropriate hanger from the Create drop-down menu (Figure 5:1.: Createmenu).

Hangers

Since the list of hanger types contains all the hangers available, regardless of the pipesize, the pipe insulation, and the type of the steelwork connection, you may find that thehanger type selected is not suitable for the pipe to support or is not suitable for an

insulated pipe. Avoid this situation by using the filters at the bottom of the form (seeFigure 5:2.: Fixed Hanger configurations form). This is described in Using the Filter Buttons.

5.1.1 Using the Fi lter But tons

The filter buttons (Figure 5:2.: Fixed Hanger configurations form) filter the list of available

hanger types by the following filtering criteria:

• Hanger category

• Pipe size

• Pipe insulation (YES/NO)

• Top beam type

There are ten filtering categories represented by the following ten buttons:

By default the ALL filter is activated and the form displays all available hanger categories.

To filter the list, click on one of the filter buttons. The application then prompts you to take

further action depending on the filter selected.

View: enables you to display the standard data sheets for the selected hanger.

View Config: displays a 3D view of the selected hanger configuration to enable early model

appreciation of the configuration selected.

The hanger type associated with the hanger form shown in Figure 5:9.: Modify Hanger form

is a fixed single hanger with a turnbuckle and two rods.

You can:

• Change the rod lengths.

• Make the rod lengths equal.

• Change the hanger’s configuration (still leaving it as a fixed hanger).

• Transform the fixed hanger to a variable hanger.

Each of these options is discussed in detail. As you proceed, additional buttons become

activated and are explained.

To change the rod length:



MDS User Guide

Hangers

12.05:11

• Enter the required length in the appropriate input field. The rod length is modifiedaccordingly.

Each rod has a minimum and maximum allowed length. These values depend on the limits

set by the MDS Administrator. Refer to the MDS Administrator Guide for more information.

Changing the length of one rod automatically updates the length of the other rod, such that

the total hanger height does not change.

To make the rods lengths equal:

• Click on the icon.

- Modi fy ing the hanger configurat ion

You can change the hanger configuration with the following restrictions:

• The new and existing configurations must have the same basic connection types. Aconfiguration in which the hanger is connected to the pipe using a pipe clamp can have

its configuration changed to a similar configuration with a different type of pipe clamp.However this configuration cannot be changed to a hanger with a connection to a pipelug or an elbow trunnion. The converse situations are also true.

• If the type of connection to the steelwork of the new configuration is different from thatof the existing configuration, the application prompts you to identify the steelworksection(s) accordingly.

To modify the hanger configuration:

1. Click on the icon. The fixed hanger configurations form opens with the appropriatefilter is activated. In this case it is the first filter ( ).

2. Select a new configuration from the displayed filtered list, or click on another filter button and select another type of configuration.

3. For the purpose of this particular explanation, select the T3 M2 B6 configuration fromthe filtered list.

The activated filter is not being changed. The application therefore tries to replace thecurrent hanger configuration with the new configuration based on the current pipe andbeam connections.

If the new configuration has a different beam connection (for instance a double channelconnection two beam connection for a double hanger), then the application promptsyou to identify the beam(s) for the new connection type.

4. Click on the T3 M2 B6 hanger configuration.

5. Click OK. The fixed hanger configurations form closes and the hanger form is re-displayed.

Note: The title of the form changes to reflect the new configuration.

6. Click on the icon. The Modify Hanger form is displayed.

The rod lengths are deactivated and cannot be changed because the T3 M2 B6configuration has a fixed length welded eye rod. The bottom rod length cannot bechanged either because to do so would change the total height of the hanger.

- Changing the hanger type from Fixed to Variable

To change the hanger type from Fixed to Variable:

1. Click on the icon. The hangers configuration form is displayed. The form lists onlyvariable hanger configurations. The active filter is the single-hanger filter ( ) becausethis is a single-hanger and the application assumes that in most cases you will modify

the configuration within the same hanger category. You can change the category by

connection point. The old fitting is deleted and a new fitting is created below the new

steelwork section.

If necessary, and if the hanger contains rods, they are adjusted to maintain the correct

hanger height.

If the new connection is not valid (for instance, the hanger is not vertical because the rods

are too long or too short), an error message is displayed and the application restores theoriginal hanger state.

- Adding a note

Click on the icon. You can now add a note to be displayed on the hanger drawing.

- Quick reference notes about modifying hangers

• For a steelwork section that is parallel to the pipe, use the Distance or Throughbuttons. This is not considered as a reconnection action since the fitting only moves tothe new position. It is not replaced with a new fitting.

• For double-hangers, there is one connection for each hanger. The application prompts

twice for the two beams. If only one connection needs to be modified, then for theconnection that you do not want to modify, identify the first beam again. The hanger isre-connected to the same beam.

• For hangers that are connected to a double-channel beam, the application prompttwice to identify each of the channels. A check is made that the two identified channelsections form a valid double-channel beam (that is: the same top level, facing eachother back to back).

5.5 Creating an MDS Hanger using a Manufacturer’s

Interface

There are three MDS Hanger manufacturer interfaces available for use with the MDSapplication.

1. The MDS Witch Hanger interface, which uses the Carpenter & Paterson Ltd. WitchHanger design software.

2. The MDS PSDesigner hanger interface, which uses the Pipe Supports Ltd.PSDesigner hanger design software.

3. The MDS LICAD hanger interface, which uses the Lisega LICAD hanger designsoftware.

9 Welding Application

The Weld application provides welds for:

• Ancillaries (for example u-bolts and clips)

• Sections

• JointsWelds for ancillaries and joints are created in the MDS catalogue project by the project

administrator. Most of the framework welds for sections and joints are also created in this

way. However, some welds are not part of the template and must be created by you during

support creation.

The creation/modification/deletion of welds is explained in the following sections.

9.1 Creating a Weld on a Framework or Special

To create a weld:

• Select the Create Weld icon from the MDS Framework or Special Framework form.The Framework Weld Selection form (Figure 9:1.: Framework Weld Selection form) isdisplayed.

Data Access Control

12.011:1

11 Data Access Control

The teams owning the database mechanisms handle the method of controlling data access.

In addition, the following access control features allow you to specify in additional detail

what operations a user can carry out on elements in the database. This is known as Data

Access Control (DAC).

Note: To use DAC it must be switched on for the project, otherwise only the teams owning

database controls will apply.

With DAC switched on, all general users are prevented from carrying out any operation on

any part of the database unless they have specifically been given the necessary access

rights. DAC uses the following new administration database elements:

• Role defines the type of operations a user can carry out. For example, creating,modifying and deleting elements. Roles are defined as a collection of permissibleoperations (Perops).

• Scope defines the part of the database in which a user can work.

• Access Control Rights (ACRs) are a combination of a role and a scope. Users can,and usually will, have several ACRs, allowing them to carry out specified operations onspecified parts of the database.

11.1 Application Entry

When you enter the application you are presented with a list of zones where you can create

structure elements. If no such zones can be found the application does not start and an

error message is displayed.

11.2 Create Mode

When you select a pipe to create an ancillary, the application first checks if it can claim the

branch. If it cannot claim the branch, then an error message is displayed. A check is madeat branch level because another user can modify the branch while it is being supported. This

can compromise the integrity of the model because you may move the branch leg that is

being supported.

If you can claim the element, then a further check is made to see if you have sufficient

access rights to create an atta. If you do not have sufficient access rights, then an error

message is displayed.

In create mode you may decide to create the connections to structural steel. A check is

made to determine whether or not you can:

• Claim the steelwork

• Create SNOD elements



12.011:2

MDS User Guide

Data Access Control

If you can do neither of these, then the Create, Modify, Force Connect and Delete icons are

deactivated.

If you can create a support, you are allowed to modify or delete the same components that

have been created and to modify or delete additional components (for instance: elbow,

reducer, bend).

11.3 Additional Requirements for MDS with DACS

In the creation of dummy branches and trunnions you may be required to create and set

attributes of other piping components. These are:

Create

Branches For the creation of dummy legs/trunnions.

Tees For the creation of dummy legs/trunnions to straight pipe.

Cross For the creation of dummy legs/trunnions to straight pipe.

Modify

Elbow ARR, LEA, CREF, ORI.

Reducers CREF.

Tees All attributes for tees.

Cross All attributes for crosses.

12 Application Data Sheets

The MDS application is supplied with a series of support data sheets. These are used as the

default set of support configurations. The PARAGON defaults database supplied with the

application reflect the dimensions and properties specified in these data sheets.

The dimensions and properties can be changed from their default values for specific office

or project environments. Refer to the MDS Administrator Guide for more information.

Note: The support data sheets MUST NOT be considered to be the master office or project

support standard. The office or project must still use their own support standards and

configure the PARAGON defaults database to suit their own requirements. These are

described in the MDS Administrator Guide.

MDS Health Check Utility (HCU)

12.015:1

15 MDS Health Check Util ity (HCU)

15.1 Description of HCU

MDS creates supports across four disciplines: structural, piping, electrical and HVAC, and it

is possible one of the disciplines could inadvertently corrupt the multi-discipline support in

some way. This utility checks for the existence of any problems.

Separate checks are performed for ancillaries, structural supports, hangers, trunnions and

groups. Ancillaries which are part of structural supports (e.g. /DATUM) are checked as part

of the structural supports, using the ancillary checking method.

After the HCU has completed the checks, a report is created which can be displayed on the

screen, or it can be in the form of a text file or a comma separated variables formatted file.

The checks that are carried out are listed below:

• Ancillaries

• The ancillary is still valid for the pipes.

• Bore

• Material

• Insulation thickness

• Temperature

• Elevation

• The ancillary has valid

• Specification references (SPREF)

• Guide references

• Description values for standard supports

• Any other reference

• Check for unknown references

• Supports

• Check support type exists in available types

• Check SREF and DATUM exist

• Check specification references (SPREF)

• Ancillary check DATUM atta

• Check for support structure existence

• Structures have members

• Check for valid group members

• Check frameworks have members

• Check for unnamed elements

• Check any other references



12.015:2

MDS User Guide


• Check for valid description values for standard supports

• Run MDS Integrity Checker

• Check for unknown references

• Hangers

• Check ATTA exists

• Data consistency check on RESTRAINT

• Check for valid group members

• Check component names valid

• Check for valid SPREF of atta

• Trunnions

• Data consistency check on trunnion BRAN

• Check for correct name of trunnion BRAN

• Check for correct configuration for an MDS trunnion (correct straight pipe, elbow,reducer or tee is used)

• Check for correct main line specification

Note: All existing checks that are performed by the MDS Integrity Checker, which is

executed on completion of a support (Ending the Creation of a Support), are included

in the supports check section.

15.2 Running the HCU

1. The utility is accessed from the MDS main menu. Select the Utilities pull-down menuand select MDS Support Health Check. The following form is displayed.

Figure 15:1. Health Check Utility form

2. The list of supports is initially blank. To load supports for checking, select Al l or CE and

Below from the Add pull-down menu.



MDS User Guide


12.015:3

The CE and Below option loads all supports below the current element (CE), or if at anelement which is part of a support, e.g. SCTN of a structural support or ROD of ahanger, then that single support is loaded. Groups are counted as one support, and the

group name is displayed in the list (e.g. PS05555, where the group may consist of /PS0555[1], /PS0555[2] etc. The whole group is loaded if one support, or part of onesupport is loaded.

Frameworks with multiple crossbars are counted as one support.

Any supports which are not valid and so cannot be loaded into the list for checking (butare still, in some part or way, MDS supports) are recorded in a temporary load list file,e.g. MDS-HEALTH-CHECK-LOADREPORTONLY-21Mar2007-093214-dat (or csv asappropriate). Unnamed supports are also included in the file.

The load errors file is stored in the %pdmswk% directory and can be viewed byselecting Load Errors Only from the View Report menu.

3. The Remove option allows you to either remove Al l entries in the Supports list, or toremove selected entries from the list.

4. Click on an Output Format option button to select the required format for the healthcheck report. The options are as follows:

• If the screen option is selected, the report is output to the command window.

• If text file is selected, the output is written to a text file (e.g. MDS-HEALTH-CHECK-REPORT-21Mar2007-0931214.dat) in the directory specified in the Directory field.This directory defaults to %projcodeinfo%, where projcode is the Project Code (e.g.TWD). If %projcodeinfo% does not exist, then %pdmswk% is used as the defaultand is displayed in the field. If an invalid directory name is entered, an error alert isdisplayed and the file is not written. If the field is left blank, the default directory isused (%projcodeinfo% if it exists, otherwise %pdmswk%), following an error alert.

The appearance of the text file output is the same as the screen output.

• If CSV file is selected, the same directory rules apply as for a text file, but a csv(comma separated variables) file is created. The file naming convention is the sameas for a text file, except that a .csv extension is used. The csv output representsdata under column headings, and can be viewed in a spreadsheet application (e.g.Excel).

5. Once the supports have been loaded and the output format selected, click on the Apply button to start the health check. Once the check is complete, the report is outputfor screen or file, as described above. In addition to the file described in step 3, atemporary file of the report is also saved in the %pdmswk% directory.

6. View the report by selecting Load Errors Only or Complete Health Check from theView Report menu.

7. Click the Dismiss button to exit the Health Check Utility.

15.3 Example Health Check Report An example of a typical screen/text file output is shown below. The report concludes with a

list of the numbers of errors/warnings found and the number of supports checked.
