Agenda

• Why develop information standards for the process
  plant industries?
• STEP APs for process plant
• Industry use of AP 227
• Extending AP 227 capabilities for other industries

3
Stakeholders in the Process Plant Industries

• Process Industries includes
• chemical, gas processing, petrochemical,
  petroleum, pharmaceutical, power generation
• food beverage, pulp paper, water water
  processing
• Process Plant Industries include
• owners/operators of process plants
• engineering, procurement, and construction (EPC)
  companies
• equipment and component suppliers
• information technology suppliers

4
Process Plant Data Cycle
Its a Recycle Process !
Major Interfaces
Business Opportunities (RD)
5
Need for Information Exchange Standards

• Industry faces heterogeneous CAD/CAE environment
  -- in constant state of flux
• Process plant typical life 25-50 years
• CAE/CAD technology cycle 5-10 years
• Technical information is reused over the life of
  the project, process, and plant
• Large savings possible when engineering,
  procurement, construction, and operation can use
  diverse CAE/CAD and ERP systems
• Standards enable these savings

6
What is a STEP Application Protocol?

• AP defines the usage of STEP for a defined
  application context
• driven by industry information requirements
• uses activity modeling, usage scenarios, and
  information modeling
• specifies conformance requirements for testing
  implementations
• Enables reliable information exchange

Information Standards for the Process Plant
Industries

• Industry leaders exploiting IT and data exchange
  to improve project and plant performance
• hindered by lack of effective exchange standards
  for process models, PIDs, 3D plant models and
  life cycle information
• Move to international standards and broader
  industry collaboration
• PIEBASE - global coordination among industry
  consortia ECOM, EPISTLE, pdXi, PISTEP, PlantEC,
  PlantSTEP, POSC, POSC/CAESAR, USPI-NL,
• Segments of the process plant industries are
  defining standards for sharing information
• STEP application protocols and data warehouse
  capabilities

9
APs for the Process Plant Industries

• AP 212, Electrotechnical Design and Installation
• AP 221, Functional Data and their Schematic
  Representation for Process Plant
• AP 227, Plant Spatial Configuration
• AP 231, Process Design and Process Specifications
  of Major Equipment (cancelled)

10
AP 227 - Plant Spatial Configuration
