1 Purpose & Scope

1.2 Purpose.

Work instruction for 3D modeling of pipe support, using Vetco Aibel’s pipe support application software in PDMS.

1.3 Scope.

Describe the routines for modeling pipe support in PDMS, and the information Vetco uses for fabrication that is set in design.


2 Pipesupport Forms

2.2 Shortcut menu

The Pipesupport shortcut menu is called from the multi discipline Design menu.

“Pipesupport > PS Form – 11.5”

The Pipesupport shortcut menu (SH_CUT), as shown below, is the entrance to all Pipesupport design forms and functions for Vetco Aibel.

• From the buttons under the “VETCO PS forms” paragraph you call the

forms for setting default design information like storage area and specs. All the information forms are situated here, as well as the “check pipesupport” function.

• From the buttons under the “Commands” paragraph you can navigate

easily between all the different components of the pipesupport as well as query attributes and unclaim design elements.

• The buttons under the “VETCO Specials” paragraph are used for

interaction between pipe and pipesupport and various functions to delete pipe supports. It is important to use this delete function and not the generic PDMS delete function to maintain correct references in PDMS.


2.3 Setting defaults Pipesupport shortcut menu > Set Defaults

• Select project component Spec. • Select project steel Spec. • Type in required storage zone for restraint. • Type in required storage zone for frame or

identify by pressing “Ce”. • Enter desired prefix for support name. • Config grabs the area name from the

current pipe. • Index is the number the application starts

counting at when selecting a new sequence number.


3 Forms for creating and modifying supports

3.2 Create pipesupport form

[Pipesupport shortcut menu > Create]

• Create Attachment • Create Pipesupport • Create Hanger (If you only want a section with connection to pipe, without

any Pipe support standard component) • Create/Modify PCLA • Create Trunnion • Create Sctn • Create/Modify Panels • Create/Modify endplates, doublerplates and base plates. • Copy Support function • Create & Modify Spring support


3.3 Create Attachment

[Create pipesupport form > Create Attachment] • Create Attachment – Identify element on branch that

will be in front in hierarchy. • Cr Atta, branch with no comp – For pipes with no

components. • Move Atta through element – Identify a design element. • Move Atta distance – Enter value for Atta to be moved

along pipe

3.4 Create Pipesupport

[Create pipesupport form > Create Pipesupport] This form creates Hanger,Rest,Frmw,Sbfr,and Sctn and sets all necessary references. Required position in Hierarchy is ATTA

• Generate new pipe Support Name by pressing “New”. • If the new pipesupport is to be connected to an existing

pipe support framework, tick the “No Steel” toggle option • Direction & Choose Horizontal or Vertical pipe direction • Choose frame type • Direction frame • Select steel profiles • Distance from Bottom of pipe • Enter A length or select identify button A • Enter B length or select identify button B • Enter C length • Choose Placement of support in hierarchy • Create support


3.5 Create/Modify PCLA

[Create pipesupport form > Create/modify pcla] This form creates/modifies pipe support standard details (Shoes, line guides etc.) Required position in Hierarchy is HANG.

• To create new components. • Select Create/Modify • Select Type • Choose non-standard for components

that is intended for other pipe sizes than the current pipe.

• Select component. OBS! Remember to

select the component with correct material code. In the Ettrick project the material code is generally PR (SS).

• Rotate by orientating, rotation (or

Direction). • Change design parameters if

necessary. 1 = shoe length 2 = shoe height.

• Move Pcla by distance. • Create/Modify or Delete Pcla.


3.6 Create Trunnion [Create pipesupport form > Create Trunnion]

• Get position and name info from bar

menu(must be placed on Atta) • Pipesupport Name. • Connecting type, straight pipe or elbow. • PS-line. • Choose direction for the trunnion • Choose trunnion length, L • Choose trunnion size. • Choose end-/cap-plate for trunnion. • Choose trunnion base plate material. • Select what steel trunnion to be connected

to or create new. • If new PS- steel, choose steel direction. • Select steel profile. • Create trunnion.


3.7 Create Sctn

[Create pipesupport form > Create sctn] • Get position – If current element is sctn, and then choose pline. Then Start or End and the position will appear in position gadgets. • Select create or modify • Select Direction • Set length • Choose profile • Select material • Select witch pline the sctn will be orientated around • Apply

Modify: • Select endpoint to modify. The four ways to extend length: • If the beams & structures applications has been opened, then to connect your sctn to another use Connect STL SH (necessary with write access to existing steel etc) • Extend end through pline • Extend end through ppoint • Enter Value in extend gadget. • For Bracing use – Brace Extend • Modify Cutting plane direction for sctn with DRNSTA and DRNEND.


3.8 Create/Modify Panels

[Create pipesupport form > Create/Modify Panels]

• Navigate to SCTN. If no SCTN available then navigate to SBFR and set position manually (or

use the get position from the bar menu on the top left) • Choose between normal and Hilti plates, from bar/heading. • Select position by section Pline start/end (or by typing the co-ordinates) • Select view-direction related to figure, to set panel orientation. • Fill in required size from figure, variable dim A, B etc. • If needed, fill in bolt information. If no bolts are required, select No in bolt gadget. • To modify panel navigate to existing PANE then select modify and enter new values.


3.9 Create/Modify endplates, doublerplates and base plates. [Create pipesupport form > Create cap plates]

• Select Type, material and description. Cap plates

will only be created on RHS profiles and always creates two plates, one in each end, delete one if only one is required.

• Doubler plate will automatically be placed in start

position of sctn, use Move D.P. button to move to end position

• Base plate same as doublerplates.

3.10 Copy Support function [Create pipesupport form > Create Attachment]

• Navigate to desired support (REST) and press

Copy Ce. Enter new name if required. • There are several actions to select from in the

pull down menu. • Copy Pipe Support Steel • Copy Single Line Support • Copy Pipe Support Along Pipe • Move Pipe Support to New Zone. • Move Support Along Pipe • Include Support. This is only possible if the

zones are in the same database. • Incremental multiple copy

When selecting the different types of copy functions enter the desired values and press the Move/Copy Support button. The multiple incremental copy functions open a new form as shown below.


• This form allows you to make several copies of a single

support along the same pipe. The naming is done automatically. Enter the desired number of new supports and the distance between them.

It is important that no one else is working in the same pipesupport zone when using the multiple incremental copy function. Otherwise there is a slight risk one might end up with elements using the same name and this will again result in crossed references and loss of work. All copy functions are inclined to produce errors usually caused by write access, status, locked elements etc. When finished copying, run Check Support from the Pipesupport Shortcut Menu to ensure data consistency.


3.11 Create & Modify Spring support

[Create pipesupport form > Create/Modify Spring] Navigate to ATTA The spring button triggers a question form asking for constant or variable spring.

Variable spring

• Select Create or Modify and the spring position/direction • Enter values as found in the Carpenter & Paterson spring

catalogue • Enter tag number as described in the project

documentation • ALWAYS use delete function in this menu to delete

springs.


Constant Spring (Same procedure as for Variable Spring)


4 Restraint Information - Restform

4.2 Restform

[Pipesupport shortcut menu > Restform] The Pipesupport information form is mainly for filling out info. For the current support in the list. This form contains three different parts. • Restraint Information • Hanger Information • PsStandard Details NB! Apply button must be pressed after each part is filled in.

4.3 Restraint Information

Enter Designers signature, Revision, Current status, Fireproofing, Priority and Hookup information. Status A1: Design started Status A2: Preliminary modelled Status A (30%) in Ettrick Project. Status B1: Self-Check Status B2: Clash Check / Review Status B (70%) in Ettrick Project. Status C1: Issue start Shop Drawing Status C2: Issued for construction Status C (100%) in Ettrick Project. NB! Remember that cog and item numbering is done every time you press apply.


4.4 Hanger Information

For all hangers in the list these items must be filled in: • PSLine. • Welded att: • PS Function • Design loads • Blast loads • Slug loads Psline is the link between the pipe and the standard components. This is also used in Umoe Application, as a link between pipe and standard components. Psline can be set manually, but since there may only be one pipe pr. hanger, it should always be set to A. PS Function: Select required function by ticking

4.5 PsStandard Details

Enter on each component (usually set automatically when pressing the apply button) • Item number • Installation Code • Material • Stockno Enter if required on non-standard components or drawing comments • Length • Height • Width • Pcla comments (Just in design) • Drawing comments (Comes out on pipe support detail drawing)

4.6 Trunnion Information Trunnion cutlenght must be calculated with or without repad form the bar menu. From here one can also change trunnion spec.


5 Pipesupport steel information form

5.2 SctnForm

[Pipesupport shortcut menu > SctnForm]

This form, Pipesupport steel information form, is mainly for filling out info for all steel elements under the hierarchy /PS-“NAME”/SBFR1. In the list all elements contains an MTO items, fittings, panel and sections. The designer needs to check if all information is correct. This form contains two different parts. • Sub frame Information • Bolt Information

5.3 Sub frame Information

• Material - Required on all elements • Stockno - Must be set on PANE and FITT. • Drwg note - Add a drawing comment on element, ex. Cut to fit. • The buttons “Set all sctn to Stainless/Carbon” will only change SCTN not PANE or FITT. • The buttons “Set HolloBolt Info.” Adds expansion bolts to SCTN or PANE. • The buttons “Add/Remove Dummysteel” Sets the Description attribute on any FRMW item to

‘DUMMYSTEEL’ which in turn excludes the item from the mto item list on the drawing and the weight calculation.


5.4 Bolt Information

• Bolt Grade (If bolted connection, select bolt grade) • Bolt Size (When bolt size is selected, the standard bolt length’s will be listed for selection) • Bolt Length • Number of Bolts • Number of Nuts/Washer (Double the amount of bolts.) To check all information:

5.5 Datum point [Pipesupport shortcut menu > Datum point] It is important to set the datum point. Otherwise the key plan will not be generated when drafting the pipe support. See pipe support detail standard for guideline to position DP correctly.

• Navigate to SCTN or PANE. • Make your selection. • Apply


5.6 Steel to Drawing

[Pipesupport shortcut menu > Steel to Drwg]

• This form will add reference or existing steel to

the drawing (setting the :StlDrwgRef on SBFR). • Click on Identify and select required SCTN or

PANE’s. PDMS can hold no more than 5 references in total.

• Alternatively add the element you are currently standing on by pressing the AddCe button

5.7 Check Support [Pipesupport shortcut menu > Check Support]

• When the Pipesupport is finished run the

Check Support program. You will find a summary of the support including Welded attachments and reference steel.

• In this example we find the COG and

weight is not properly set. Remedy this by running the Restform to calculate weight etc. for new elements that has been designed since the Restform was last run.

• When the list is cleared of error messages

the support is ready for drafting.


6 Shortcut menu - bar menu

6.2

• The bar menu contains methods to modify href/tref, sctn, support

names, trunnion specifications & length and trunnion base plate.

• In the misc. submenu there are macros for sorting pipesupport

elements, identifying pipe supports on pipes, counting supports, calculating trunnion stresses, identifying support forces and viewing trunnion detail plots created in draft for use on fabrication Iso’s.

• Under the Global and Proj. submenus there are more specific macros.

Your PDMS administrator will store new functions typically created for individual projects or other ad hoc needs in this location.

6.3 Modify hanger head/tail [Pipesupport shortcut menu > Pipesupport Bar > Modify > Modify hanger head/tail] This function is for setting the connection HANG -> ATTA or HANG -> SCTN


6.4 Modify sctn

[Pipesupport shortcut menu > Pipesupport Bar > Modify > Modify Sctn] Modify profile type from the pull down menu (Remember to run SctnForm to set materials). Flip Bangle turns the SCTN by it’s LTS in 90 degrees increments. Extend Sctn allows you to stretch or shorten a SCTN by identifying PLINE on any other SCTN (Remember to run RestForm to calculate new cog & weight)

6.5 Modify support name

[Pipesupport shortcut menu > Pipesupport Bar > Modify > Modify Support name] Navigate to REST and enter new name. This will change REST and FRMW names along with references.

6.6 Modify trunnion

[Pipesupport shortcut menu > Pipesupport Bar > Modify > Modify trunnion]

Navigate to trunnion (BRAN). Modify Size and length.

To reselect pipe spec for trunnion go to [RestForm shortcut menu > Restform > Trunnion > Change Spec ]


6.7 Modify trunnion plate

[Pipesupport shortcut menu > Pipesupport Bar > Modify > Modify trunnion base plate] Check the pipesupport standard to identify allowable plates. Never change des-parameters on trunnion plates manually. If you do, the plates will not be included in the material takeoff and subsequently not be ordered.

6.8 Sort elements in SITE or ZONE [Pipesupport shortcut menu > Pipesupport Bar > Misc > Sort in hierarchy] Functions for sorting REST and FRMW

6.9 Mark pipe [Pipesupport shortcut menu > Pipesupport Bar > Misc > mark pipe] Navigate to pipe. This function marks the pipe with pipesupport placement, functions and name.

6.10 Number of supports in project

[Pipesupport shortcut menu > Pipesupport Bar > Misc > Number of supports in project] Gathers number of pipe supports in the different areas and summarises in the command window.


6.11 Stress check trunnion

[Pipesupport shortcut menu > Pipesupport Bar > Misc > Stress check trunnion]

Enter information: • Pipe out diam • Wall thickness of pipe • Corrosion allowance • Trunnion out diameter • Wall thickness of

trunnion • Trunnion length • Design pressure • Pad thickness • Weld length • Longitudinal operating

force • Circumferential

if new branch is selected.

If the trunnion has been modelled, then by selecting in list pipe diameter will appear. NB! All information must be entered. No gadgets shall be empty, type 0 for zero force or Corr. Allowance. Check Trunnion – Example on Quick check:


View Hole Check & Print file – (NB! You must print to get a file Path: H:\pdmsuser)

6.12 Loads to structure [Pipesupport shortcut menu > Pipesupport Bar > Misc > Loads to structure]

6.13 Check trunnion detail plot

[Pipesupport shortcut menu > Pipesupport Bar > Modify > Check trunnion detail plot]

• This form is for viewing the detail plot files that are used on

fabrication isometrics. Standard path for files is %data%\l\fiso\wa (ex. p:\r115\003630\data\l\fiso\wa)
