ISO 15926 TUTORIAL - LESSON 10 - Mapping a (mini)Plant

Finally we make a take-off from a small P&ID and write, as homework, some code:



Take-off

First we make a take-off of all objects, and, where not shown on the P&ID, give them a subtag:

Homework

For above items that are marked yellow:

  1. write their declaration
  2. classify them where required with the Class in column 3 (use ClassificationOfIndividual),
  3. define the whole-part assemblies (use AssemblyOfAnIndividual).

Connections

Then we define the interconnections between these objects:

CONNECTIONS (in stream direction)

01-100-PE-N-OUT B001-N1 FLANGED CONNECTION Direct
04-100-PE-N-OUT B001-N2 FLANGED CONNECTION Direct

PSV0014 04-100-PE-N-IN FLANGED CONNECTION Direct
04-100-PE-N-IN 04-100-PE-N-OUT INDIRECT PIPING CONNECTION Indirect

Obviously this information shall be automatically generated by the P&ID software, any time that a new revision has been issued. But unfortunately the P&ID software suppliers are not interested, as far as I know.

Homework

Write one template instance for each type of connection that is marked yellow, using ClassifiedDirectConnectionOfTwoIndividuals and ClassifiedIndirectConnectionOfTwoIndividuals.

Properties

Finally we write templates for the properties listed in the left upper corner of the P&ID and for the relief valve:

POSSESSOR INFORMATION ABOUT NAMED OBJECT VALUE UNITS
B001 DIAMETER 1000 MILLIMETRE
B001 HEIGHT 3000 MILLIMETRE
B001 NOMINAL CAPACITY (volume) 2.4 METRE CUBED
B001 UPPER LIMIT ALLOWABLE WORKING PRESSURE 10 BAR GAUGE
B001 UPPER LIMIT ALLOWABLE TEMPERATURE 50 DEGREE CELSIUS
P001-STRM NORMAL VOLUMETRIC FLOW RATE 5 METRE CUBED PER HOUR
P001 DIFFERENTIAL HEAD 2.5 BAR
P001 UPPER LIMIT ALLOWABLE WORKING PRESSURE 10 BAR GAUGE
P001 UPPER LIMIT ALLOWABLE TEMPERATURE 50 DEGREE CELSIUS
PSV0014 SET PRESSURE 6 BAR GAUGE

Homework

Write all ten template instances to represent above information. Keep in mind that all above information is about the Asset Requirements Class, so the templates are for classes.

It is true that the P&ID lists this information for the individuals B001 and P001, but, as we say in Dutch: "Papier is geduldig" (paper is patient).

For clarification: These properties are requirements that must be met by the ActualIndividual and, because of their classification with the Asset Requirements Class, also by the NonActualIndividual.
ActualIndividuals ARE what they are, with characteristics that are almost 100% certain different from the requirements, of better said: not exactly the same.

Classes have range properties, individuals have point properties. Even a requirement for 316SS has a range, because when the supplier offers a better material for a 316SS price that may be acceptable. But when an individual is made of 316SS, THAT IS A FACT. The only ‘range’-like aspect is in the accuracy of measurements or material analyses.

So the P&ID tells what, topologically, the plant looks like. The fact that P&IDs also show equipment and stream data is a relic of the old days, when we didn't have computers, so that documents also served as data base. The definition of what the characteristics of the plant items shall be is given by the Asset Requirements Class, usually defined by a technical specification (commodity materials by a Product Specification or an acceptable standard).

The first two properties are instances of ClassOfShapeDimension (use ClassOfIndividualHasDimensionedShapeWithValue ), and the rest are instances of ClassOfIndirectProperty
(use ClassOfIndividualHasIndirectPropertyWithMaximumValue for the ‘UPPER LIMIT’ properties, and ClassOfIndividualHasIndirectPropertyWithValue for the rest ).
Assume that the tags CO-B001 and CO-P001 (CO = ClassOf) have already been declared and that B001 and P001 are their respective members. Furthermore P001-STRM is the Liquid Stream through P001, with CO-P001-STREAM to attribute the above value to.

In a next revision you can find the correct code, allowing you to compare.
