What you will be able to do.

Junior process, instrument and project engineers; operators and supervisors moving into technical roles; maintenance planners and HAZOP scribes

The P&ID is the drawing every discipline, every HAZOP and every permit depends on, and it is also the one most people read only partly. The course covers ISA-5.1 symbols and identification, instrument and line tagging, control loops and interlocks as drawn, and typical site lead-sheet conventions, then has participants develop a P&ID from a PFD and mark up an existing one for a change so that they understand what a revision costs.

  • Read instrument symbols, function identifiers and loop numbers to ISA-5.1 and the site lead sheet
  • Trace process lines, utility connections, spec breaks and insulation classes from the line number
  • Identify control loops, interlocks, relief devices and their set-points as drawn
  • Develop a P&ID from a PFD, including valves, drains, vents and instrumentation needed for operation
  • Mark up a P&ID for a change and follow it through MOC and as-built
  • Spot common drawing errors and omissions before they reach a HAZOP
