EQUIPMENT MODELLING USING TEMPLATE-Chapter 4.pdf

CHAPTER 4 4

Equipment Modelling Using Templates

The previous chapter described how equipment items can be created using primitives arranged in 3D space but with no relationship between them. AVEVA E3D enables equipment templates to be created and instances of the template placed in the model.

4.1

Equipment Template Overview

An equipment template is a collection of primitives that make up the equipment shape grouped together under a Template (TMPL) element. The template definitions are held in a Design Design database which is referenced when an instance of the template is created. Templates can be of two types: 



Non-parameterised templates Non-parameterised templates - create elements of fixed design and dimensions. Parameterised templates Parameterised templates – contain rules that allow the primitives of the equipment to be re-sized and re-positioned or supports, if any, to be added or modified.

 The creation of equipment templates id outside the scope of this training guide. 4.2

Creating Standard Equipment Items

On the EQUIPMENT EQUIPMENT tab, in the Create Create group, selecting Standard Standard from the Create Equipment Equipment button options list displays the Create Equipment Equipment form. The form enables an equipment item to be created by making a series of selections based on the styles of various equipment templates. There are two methods are used to select the appropriate template, a Selection Table or Table or a Specification. Specification .

4.2.1

Selecting a Template - Selection Tables Clicking the Selection Table Table radio button on the Create Equipment Equipment form enables the Selection Table Table options list that contains the available selection tables.

Depending on the selected table, the Type Type options list enables different types of equipment to be selected, depending on the contents of the table.

Selecting a different Type from Type from the options list changes the contents of the grid. Selecting a grid entry displays a model of the selected template in the 3D View at the bottom of the form.

4.2.2

Selecting a Template – Specifications Clicking the Specification radio button on the Create Equipment form enables the Specification options list that contains the available specifications.

The middle part of the form contains two lists. The upper one is the Current Selection which is empty at the start of the process, and the lower one is the Selection list from which selections are made. The options in the Selection list depend on the Specification selected. Clicking a line in the Selection list places the line in the Current Selection list and displays new options in the Selection list.

Clicking a line in the Current Selection reverses the selection. The process continues until all choices have been made and a template has been selected. A model of the selected template is displayed in the 3D View at the bottom of the form.

4.2.3

Properties and Plotfiles

If the selected template is parametrised, the Properties button is active. Clicking the button displays a Modify Properties form that enables the specific dimensions to be modified by changing the default values. All primitives related to the property are modified, thus maintaining the integrity of the equipment template.

If a Plotfile has been created for the equipment item it can be displayed by clicking the Plotfile… button. The Plotfile usually contains information relating to key dimensions and the equipment origin.

4.2.4

Creating an Instance of the Template

Clicking the Apply button displays the Positioning Control form and the prompt ‘Pos ition E quipment Orig in

S nap (S nap):

’

The equipment may be positioned in the model using appropriate settings on the Positioning Control form.

4.3

User Defined Elements Types for Equipment

Equipment items can be created with more meaningful element types, other than EQUI, that better describe their function. For example, model elements may be called :PUMP, :REBOILER, :TANK, or :FILTER. This is achieved through the use of User Defined Element Types (UDETs). UDETs are created based on a standard AVEVA E3D element type, in this case equipment (EQUI) items. UDETs are defined in AVEVA Administration™ Lexicon module and generally have the same attributes as the base type, although some of the attributes may be hidden at the time of creating the UDET. UDETs are distinguished from standard element types by the prefix of a colon, similar to User Defined Attributes (UDAs). They also have an ActType (active type) attribute which is set to the UDET type, e.g. :PUMP. The standard Type attribute is set to the base type, e.g. EQUI. In most respects UDETs may be used in exactly the same way as EQUI elements. However, in the current User Interface there are no forms to create the UDET elements, other than where an equipment template is used. UDETs can be created using the Command Window by entering the syntax NEW , e.g. NEW :PUMP. On the Create Equipment form, the User Defined Type options list displays any available UDETs. Selecting, say, PUMP will create the equipment as an active type of :PUMP. Once a UDET has been created its ActType attribute may be changed by using the Command line syntax CHANGETYPE TO , where is another valid UDET for the Type defined in Lexicon. An EQUI may also be changed to a UDET using the same syntax.

The drawing on the form shows the exchanger with no supports and the Exchange Support property is set to a default of No Supports. Click the small down arrow adjacent to the textbox to display the Exchanger Support form. Select the Horizontal Exchanger Feet option. Click the Modify properties for Exchanger Support button adjacent to the down arrow to display the Modify Properties form for the exchanger supports, which contains a number of properties and a drawing of the supports. This form will create the exchanger supports as a sub-equipment of the UDET. Referring to the Equipment Arrangement drawing, enter the following values against the properties: A = Origin to Foot 1070. B = Feet to Feet 2870. C = Foot Thickness 150. D = Foot Width 380. E = Distance to CL 450. Click the OK button to enter the values and close the form. On the Modify Properties form for the Exchanger click the OK button to enter the values and close the form.

4.4.2.3 Specifying the Position On the Create Equipment form, click the Apply button. The prompt ‘Position Equipment Origin Snap (Snap): is displayed in the prompt area and the Positioning Control form activated. The exchanger origin may be positioned using a graphical pick, however, it is more likely that an explicit position will be given. ’

Click the Explicit Position button on the Positioning Control form to display the Explicit Position form. From the Equipment Location drawing, the following values can be derived for the origin of E1302B: E

4.4.2.4 Finishing E1302B During the equipment creation process certain data could not be specified, for example: 

The orientation of the heat exchanger.



Nozzle names and specifications

This data must be corrected after the creation of the equipment. The origin of the Heat Exchanger is in the correct position, however, from the Equipment Location drawing it can be seen that the flanged end must be at the southern end of the equipment, i.e. the equipment needs to be rotated 180º about the Z axis of the origin. Double click E1302B to enter Editor mode and display the equipment grips at the origin of E1302B. Rotate the equipment around the Z axis by 180°. Press to exit Editor mode. Right click on NOZZ 1 in Model Explorer to make it the current element. From the Equipment Arrangement drawing this nozzle should be named NS1. Select Rename from the pop-up menu to display the Name form. Enter E1302B/NS1 in the Name textbox and click the Apply button. Close the form. On the EQUIPMENT tab, in the Modify group, click the Nozzle button to display the Modify Nozzle form. From the E1302B Nozzle Schedule, NS1 should be a 100 NB 150lb Ansi Flange nozzle. Select ANSI-NOZZLES from the Specification options list, 150lb Ansi Flanges from the Generic Type options list and 100 from the Nominal Bore options list. Click the Apply button to change the nozzle specification. Repeat the operation for the remaining three nozzles, entering the following data: 

NOZZ2 – Name: E1302B/NS2, Specification: 150lb Ansi Flange, Nominal Bore: 100mm



NOZZ3 – Name: E1302B/N2, Specification: 150lb Ansi Flange, Nominal Bore: 150mm



NOZZ3 – Name: E1302B/N1, Specification: 150lb Ansi Flange, Nominal Bore: 150mm

Close the Modify Nozzle form.

4.4.3

Creating E1302A using Copy Mirror

From the Equipment Arrangement drawing it can be seen that E1302A is a mirror of E1302B with some nozzle specification differences and additional ‘feet’ to support E1302B. Rather than go through the creation process again, it is easier to copy and mirror E1302B and make the required changes and additions afterwards. With E1302B as the CE, select HOME > Create > Copy Mirror display the Mirror form. Select Rel. from the To options list to place the copy in the same place in the hierarchy as the original. Select Cursor > Element from the form menu and graphically pick the main body cylinder of E1302B. This sets the mirror plane origin at the origin of the cylinder. The coordinates of the origin are displayed on the form. Enter U in the Plane direction text box to make the plane an Up plane. From the Stacking Arrangement on the Equipment GA, it can be seen that the centreline of E1302A is 922 mm below the centreline of E1302B.

The plane must, therefore, be moved to an elevation of 109757 – (922 / 2) = 109296, i.e. in the middle of the two centreline elevations. Enter the value in the Up textbox and click the Apply button to create the new heat exchanger. Click the Yes button on the confirmation message to retain the copy and close the Mirror form.

4.4.3.1 Finishing E1302A During the copy mirror process there was no opportunity to rename the equipment or the nozzles, therefore, the renaming must be done after the heat exchanger has been created. Right click on E1302A in Model Explorer and select Rename from the pop-up menu to display the Name form. Enter E1302A in the Name textbox and click the Apply button. Do not close the form. The nozzles also need to be renamed in accordance with the Equipment Arrangement drawing for E1302A. Navigate to NOZZ 1 of E1302A in Model Explorer. Click the CE button on the name form and enter E1302A/NS2 in the Name textbox, press the Return key and click the Apply button to rename the nozzle. Repeat the process, entering the following values for the remaining three nozzles: 

NOZZ 2 enter E1302A/NS1



NOZZ 3 enter E1302A/N1



NOZZ 4 enter E1302A/N2

The nozzle specification for Nozzle N2 on E1302A is different from that of Nozzle N1 on E1302B and must be re-specified as an 80 NB 300lb Ansi Flange nozzle. Navigate to the nozzle in Model Explorer and On the EQUIPMENT tab, in the Modify group, click the Nozzle button to display the Modify Nozzle form. Verify that the Specification is already set at ANSINOZZLES. For the Generic Type select 300lb Ansi Flanges and select 80mm from the Nominal Bore options list, click the Next button and close the form. Copyright © 2013.

Creating Electrical Components

An Electrical Component (ELCONN) in equipment terms is a connection point between equipment and cables and can represent anything from an individual cable gland to a piece of electrical equipment, such as a generator. Electrical components are catalogue items and are selected from the catalogue via a selection table and are positioned and orientated within equipment in the same way as nozzles and primitives. On the EQUIPMENT tab, in the Create group, clicking the Electrical button displays the Create Electrical Component form. The form enables an electrical component to be made from the range of catalogue items available. The overall category of electrical component is selected by choosing one of the Table options. This table may be divided into sub-categories selected using the Type options and can be sorted and filtered to restrict the number of components displayed for selection. A component in the table can be selected by clicking on a row in the table. Clicking the Properties… button displays the Modify Properties form on which to set any parameterised data relevant to the selected electrical component. If there are no parameterised properties an error message is displayed:

The Plotfile button is active if a plot file of the component is available.

When the electrical component has been fully specified, clicking the Create button creates the component at the equipment origin. The bottom part of the Create Electrical Component form is changed to display a Component Position frame. The position of the electrical component may be specified by entering appropriate values in the co-ordinate textboxes or by graphically picking a position in the 3D View using the positioning control toolbar. When the electrical component has been positioned, clicking the Next button changes the form to its original state, enabling another electrical component to be created. ELCONN elements appear in the Model explorer as shown below.

Electrical components may be orientated by selecting the Rotate in 3D View command.

 If the project has been configured with User Defined Element Types based on electrical component (ELCONN) element type, they will appear in the User Defined Type list. When the electrical component element is created, it will be created as the User Defined Type selected from this list. Selecting a User Defined Element Type may change the content of the Selection Table if the table has been configured to filter on element type.
