A Quick Start to Understanding PERD Participation

The Situation

  • Industry Convinced Regulatory Authorities to Accept Performance-based Process Safety Management
  • Lack of quality data reduces confidence & jeopardizes industry credibility with respect to quantitative analysis results
    • Performance-based Processes Require Quality Management Systems that are Auditable and Defensible
    • Quality Assurance Requires Data to Validate Performance Assumptions

The solution: PERD

Imagine that your maintenance & reliability data is automatically uploaded, compared against whole-industry data, and made available to you with clear, statistically validated  guidance. It's not your imagination, it's PERD.

"A rising tide lifts all boats".  As the PERD boat rises, all participants will reap the benefits.

PERD Mission

To provide this solution, CCPS set in motion a project with the following Mission: “Operation of an Equipment Reliability Database, Making Available High Quality, Valid, and Useful Data to the HPI and CPI Enabling Analyses to Support Availability, Reliability, and Equipment Design Improvements, Maintenance Strategies, and Life Cycle Cost Determination”

PERD Provides:

  • Practical approach and Consistent work processes for data collection
    • Sound theoretical foundation based on engineering fundamentals
  • Efficient software tools for data submission
    • S/W dedicated for use by participating companies
  • Quality assurance for data analysis
    • Identification and analysis of outliers
    • Defensible and auditable results

Why join PERD

With a small investment and minimal data PERD enables user companies to leverage existing IT and MI systems to collect and submit data resulting in:

  • Improved Reliability
  • Identification of “low hanging fruit” for immediate impact
  • Minimization of unforeseen losses
  • Increased Effectiveness for
    • Information Systems Technology
    • Reliability & Quantitative Risk Assessments
    • Regulatory Compliance

With a small investment and minimal data your maintenance & reliability data could be:

  • Automatically uploaded,
  • Compared against whole-industry data, and
  • Made available to you with clear, statistically validated  guidance

Getting started

Upon Joining as a Full Participant

  • PERD provides the software & initial help to companies loading the software onto their company server
  • PERD provides initial help and guidance allowing you to contribute whatever data you have, enabling companies to quickly get involved and begin accruing benefits
  • Company data contribution means access to aggregated anonymous industry data and a path to continuous improvement

Immediate Benefits

  • Access to fundamental technical information that documents specific data user needs to:
    • Filter inventory data for populations of interest
    • Infer failure modes of interest
  • Access to work process knowledge needed to achieve company goals
  • Facilitates moving to data farming (low cost) work process rather than data mining (high cost) activity
  • Enables maximization of benefits from enterprise systems (eg SAP, Maximo, Matrikon, Meridian, etc.)
    • Provides pre-engineered solutions that can be implemented cost effectively
    • Best available info transfer between engineering and programmers

Long term benefits

  • Data Harvesting per Defined Quality Plans Provide:
    • Operating company database capable of achieving proven in use data for safety and reliability analysis
  • Data Contribution to PERD Facilitates
    • Operation of industry database
    • Industry benchmarking
    • Statistical analysis by true experts due to best data available to support their research
    • Data available for improved reliability and risk analysis
    • On going continuous improvement via reliability growth

Build upon a sound technical foundation

  • PERD Uses a Data Tier Structure That:
    • Eliminates Data Intimidation
    • Allows more rapid expansion of partial Equipment taxonomies and associated software development
  • Basic Tier Concept
    • Tier 1 – Whatever minimal data might exist – Gets people started
    • Tier 2 – Begins to provide more useful information
    • Tier 3 – Top of the PERD ladder of success

Inventory Data Tier concept

  • Tier 1
    • Location Address (e.g. Plant, tag, etc.)
    • Equipment Group (e.g. Instrumentation)
    • Equipment System (e.g. Transmitter)
  • Tier 2
  • All tier 1 data plus following data user chooses to enter
    • Equipment Type (e.g. Differential Pressure)
    • Equipment Subtype (e.g. Level)
    • Manufacturer
    • Model Number
    • Output Signal or Set Point (As applicable to equipment)
  • Tier 3
    • All tier 1 data
    • Equipment type
    • Equipment subtype
    • Plus additional tier 2 and / or 3 data user chooses to enter

Event Data Tier concept

  • All Events require
    • Linkage to tracked equipment
    • Event date (and time if applicable)
  • Tier 1
    • Data showing a failure has occurred
  • Tier 2
    • Data sufficient to infer whether failure was “Dangerous” or “Safe”
  • Tier 3
    • Data sufficient to infer true failure modes

User decides what event data to track. Event data tracked determines what level of inference is achievable.
