Methodology Step 1

 Step 1 Define the Asset (and set up the Hierarchy):

Below the Step 1 Methodology is described. See also Software Step 1.

Set up the IMS Hierarchy: Create Corrosion Loop, FLOC, Equipment, Circuits, Components

To set up the IMS hierarchy, the Plant, Site and Unit must first be setup. This is normally done by the CSA. When this is in place, the Corrosion Loop, FLOC, Equipment, Circuits and Components can be set up in IMS. This setup is typically also done by the CSA or INSP ADMIN. 

Collect Asset Information, Verify and Store in IMS

Collect all relevant asset information:

• Equipment data, e.g.,
  • Asset type,
  • Tag names,
  • Installed date,
  • As-built materials,
  • Main Components,
  • Location on the site,
  • Process design conditions;
  • Process as-operated, including excursions and special operating modes, etc.
• Documents (latest revision), e.g.,
  • Process Engineering Flow Schemes (PEFS) with their latest revision;
  • Documentation of historical plant changes and evidence of MOC;
  • Mechanical design of Equipment (general arrangement, Isometrics, etc.);
  • Material selection (reports);
  • Inspection history and records, including Wall Thickness measurements.

This asset data should be stored in IMS, mainly as specifications and attachments and verified for correctness prior to identification of potential Degradation Mechanisms.
