What is the
EPRI PIM Model
EPRI PIM Model History
 1987: EPRI Technical Report - Guidelines for Specifying
Integrated Computer-Aided Engineering Applications for
Electric Power Plants
• Background: Many CAE Systems/Application Already Developed
 Stand-alone and Unable to Share Plant Data
 Resulting in Costly Redundancies in Capturing, Handling, and
Maintaining data
• Objective: Develop Data Model Integrating All Plant Data for Use
in Developing CAE Applications
• Results: Findings Demonstrated Need for a Plant Data Model
 2010: Developed Plant Information Network (PIN) Study
Model
 2011: Updated PIN Study Model to Modern Plant
Information Model (PIM)
• Developed a Standard Handover Framework for Data and
Documents
• Developed a Standard Configuration Management Taxonomy and
Reference Model Framework
6
EPRI PIM Model Today and Thinking Forward
 An Evolving Open Source Standard for Handover
of Power Plant Data
• Incorporating
 Standard Handover Framework
 CM Taxonomy and Relationship Framework
 Leverage to support Implementation of a World
Class CMIS throughout the NNPP Lifecycle
 Eighty (80) Percent usable by US NNPP Projects
and adoptable by Non-US NNPP Projects
Business Need for
EPRI PIM Model
Operating Fleet Business Problem
 Multiple Organizations exchange information and
documents during EPC
 Transactions are primarily paper based with little
relationships established
 The creation and management of information and
documents has led to many disconnected data systems,
applications, and environments
 The same piece of information can and does exist within
many applications under different technical names with
different meanings
 Minimal attention to delivery of information in a data
format for commissioning, operations, and maintenance

PIM Model Objective: Leverage Automation to
Maintain Configuration at a Data/Document Level

Old Way of Managing
Configuration Information
 Document List is Managed in a Document
Management System that captures:
• Who
• What
• When
 Master Equipment List in a Separate Data Base:
Each Equipment Tag Number is related to:





Safety Classification
Equipment Properties (flow, pressure, temp, etc.)
Some Drawings
Vendor Information
Membership to an Engineering Program
11
Old Way of Managing
Configuration Information (cont)
 Separate System for Managing Requirements
• Design Basis Documents
• Owner Requirements
• Disconnected Database
 Multiple Databases for other Uses “copy” data
from the MEL or worse Recreates it –
• Equipment Reliability
• MOV Program
• Inservice Test Program
12
Limitations of the Old Way
 Challenges for Configuration Control of Data
• The same Data often managed in separate,
disconnected systems that complicates change control.
• Much Data is tied to the tag number that would benefit
from a different relationship structure, e.g., Vendor data
 Limited use of a defined Hierarchy of SSCs and
Documents that facilitates “Inherency” of data:
• A room ID should inherit the elevation, wall/slab IDs,
Building Number and Island Designation it is associated
and all of their attributes without having to key it in.
• An Equipment ID should inherit the system, system
grouping, and component subtype, component type,
component grouping it is associated and all of their
attributes without having to key it in.
13
Limitations of the Old Way (con’t)
 Limited use of Relationships – It is not only
Important to Make Relationships, but just as
Important to define the type of Relationship
• Document to Document Relationships. Examples:
 Doc A “is a Design Input to” Doc B
 Doc C “is a Requirement fulfilled by” Doc D
 Doc D “is a Reference for” Doc A
• Document to Tag and Tag to Tag Relationships
 Room ID – Elevation – Walls - Building – Island
 Master Tag that Groups related tags, e.g.:
o
o
o
o
Skid Equipment
Safe Shutdown
Isolation Groups (what is tagged out simultaneously for PM Plan)
Power Dependency
 Engineering Program (ISI, IST, ER, EQ, AOV, MOV)

Use Cases for
EPRI PIM Model
CMIS Use Cases
What are the Benefits of a CM
Structured to the EPRI
Guideline?
Use Cases for a Data Repository with the
PIM Architecture
 At this point, the Use Cases have been Qualitative –
The use cases presented mostly relate to areas we
have all had to deal with in a document centric world.
 The EPRI ANT Integration Committee has requested
Quantitative Use Cases with Lifecycle Costs and
Benefits – This is planned for 2013
 EPRI will benchmark multiple global, high-risk, highconsequence industries that have been through the
transition of a document centric to a data centric Plant
Lifecycle Management System to determine the real
value and payback realized, as well as lessons
learned.

 Manage Requirements and Conduct more thorough
Design Impact Reviews when the:
• Licensing Basis Changes (RAIs),
• Detailed Design Changes (Owner Request, RAIs),
• Construction Changes (Field Change)

the DCD, COLA,
other Licensing Info)

Use Cases for EPRI PIM during EPC
 Develop and Control Margins
 Manage Requirements and Conduct more thorough
Design Impact Reviews.
 Manage Design Inputs that change often during EPC
 Manage Unverified Assumptions –Chaining Impact of
a Design Document with a UVA on Issue for
Construction

Information if the Response Basis Document Changes
 Single Source of Configuration Controlled Data for
Engineering Programs, ITAAC, Construction, etc.
 Satisfied Owner/Operator during Handover and
Turnover to Utility
31
Use Cases for EPRI PIM after Operational
 Modern Plant Lifecycle Management (PLM)
Systems are Data Driven
 Access to Licensing Basis and Requirements to
Support Operability Determinations and
Functionality Assessments
 Tool to conduct Design Impact Reviews to
support Plant Modifications and 50.59 Evaluations

 Live Demonstration of PIM - The Power of Data
 Discuss Kickoff of Industry EPRI PIM Working
Group Teams
 Discuss Industry Adoption
