Process Documentation Services

Process Documentation Services

Small process modifications to piping and instrumentation diagrams take place routinely at operating facilities. Many times, process documentation is not properly updated when small changes take place, and these small changes can add up over time, significantly affecting existing documentation. In some facilities, process documentation does not exist as all. Process Engineering International performs services to update or to develop process documentation that reflects current operations. Examples of such services include:

  • Heat and Material Balance Documentation / Updates
  • Process Flow Diagram Updates
  • Piping and Instrumentation Diagram (P&ID) as built walk downs and updates
  • Relief device program development and documentation
  • Equipment and Instrument Lists
  • Equipment Sizing Calculation
  • Documentation of Hydraulics
  • HAZOP Action Item Resolutions

Additional Capabilities

  • Technical documentation preparation for Request for Proposals going to vendors, detailed design companies, or EPCs.
  • Bidder Clarifications and Bid Package Evaluation
  • Witnessing Performance Testing
