This Wiki helps User understand the logic used for Shop and Field weld in OpenPlant Isometrics Manager CONNECT Edition which can be utilized for configuration.
All components in the OPM/OPIM model need to be tagged as either shop or field.
For isometrics a spool is something that is made completely in the shop. A skid is interpreted as an erection site
Determination of the shop or field status is controlled by a set of (user) rules. The base principles:
So we start with every component. fastener and joint tagged as spool. The following rules apply:
#1 Component rules
Component rules are based on component properties and determine if the component should be set to field.
The standard configuration (Configuration Manager > Automatic Iso Splitting > Spool Settings)
Each line holds a rule, user can add where needed:
The states that every component marked as field in OPM is set to field in OPIM
Gaskets, bolts and clamps are forced to field even if not done so in OPM.
This is done to cover components that do not have a SHOP_FIELD value or where the SHOP_FIELD value is not correctly set in spec or by user
Example: SIZE2 < 2
Example: Force every component with main port size smaller than 2” to field.
#2 Component port rules
Port rules determine if a port is to be tagged as spool breaking. If so the joint is marked as field.
The standard configuration (Configuration Manager > Automatic Iso Splitting > Spool Settings).
All ports with an end prep FL (Flanged), IF (Wafered) or CL (Clamped) is seen as spool breaking.
Example: SIZE < 2
Example: All ports with size < 2 are seen as spool breaking. A bit similar to the example used for component rules but more granular. The rule here would for instance mark a <2” branch port on as spool breaking but not the 8” main/run port
#3 Loose components
With component rules and port rules applied there are component that are still shop but have all their ports/joints marked as field. An example is a flanged tee that gets an empty SHOP_FIELD in OPM. Given the port rules are ports are tagged as spool breaking. User can configure what to do with these “loose” components:
The above settings would force the flanged TEE to field. There are separate settings for pipe and fitting. Please not that if a loose pipe/fitting is not forced to field, it will be assigned a spool number.
#4 Additional settings
Treat sheet break as spool break: not everybody likes a spool to continue from one sheet to another.
Ignore spool breaks for design system. Not mentioned in the component/por rules is the spool break note in OPM. With a spool break notes the joint closest to it will be set to field. This option is just there to ignore OPM spool breaks.
#5 Use design system settings
When this option is checked all components with SPOOL_NUMBER = 0 are marked a s field, the rest is set to shop. OPIM stops thinking.
