Commissioning and Start-up Document Development

Axis-developed Start-up and Commissioning documents typically cover everything required to introduce hydrocarbons into a given facility. Some of these functions include:

  • Purging & Filling
  • Pressurizing equipment/systems
  • Initial Startup of equipment

 

The start-up documents are meant to contain sections with the required resources necessary for the start-up team to complete their work.  Some of these sections are as follows:

  • High level system descriptions
  • Company policy requirements, work process guidelines, checklists, permits, etc.
  • Detailed purging and filling procedures (at P&ID tag level detail)
  • Detailed pressurizing procedures (at P&ID tag level detail)
  • Detailed initial startup procedures (at P&ID tag level detail)
  • Annotated/Marked up P&IDs showing proper valve positions, purging/filling locations, etc.
  • Valve alignment tables for each start-up scenario

 

Axis typically includes complete valve tables as part of the start-up document deliverable. These valve tables are intended to line up a complete facility for the introduction of hydrocarbons.  These valve tables can include all isolations, LOTO and prerequisite valve positions for workpack execution. Axis-developed valve tables often cover all manual and DCS operated valves that are either OPENED or CLOSED in normal operating conditions.

Our experience has shown that most valve tables will contain the following information:

  • Tag Number and Tag Description
  • Normal Position (NO, NC, CSO, CSC, LO, LC)
  • Fail Position (if applicable) (FO, FC)
  • LOTO/blinds
