PLSS Condition History Overview

Take Note

This overview explains the PLSS Equipment Condition Histories (ECHs) in IMS. To learn more about ECHs see IMS Condition Histories (ECHs) across Discipline.

The Equipment Condition History (ECH) is used to record all the information obtained during inspections (except for thickness data). All significant events in the life of the Equipment should be recorded with an ECH. Writing the inspection narrative is the primary and most familiar function of the Condition History. However, there are other major record activities that are also accomplished with the Condition History. It is important to use each of the major functions.

The Condition Histories are written for the Equipment IDs (that's why we call them ECH - Equipment Condition History). Once an ECH is written and approved, it will be a permanent record. Once an ECH is written, it will be a permanent record that can be retrieved from either its active location or from a records archive or salvage location. 

The ECH window is flexible enough to meet all needs for recording the significant Events pertaining to any Equipment. ECHs can be divided into two types:

• Event or Opportunity Driven: This ECH is not linked to a Schedule, but an event is recorded, e.g. rerate performed, significant process change, a forklift dented the shell, etc. If no inspection data and codes are recorded either, this is referred to as a “Narrative Only” ECH.

• Schedule Driven: This ECH credits one or more Schedules and describes the work and/or findings associated with the credited Schedule(s).

The ECH is used to Credit the different Schedules, after the inspection or other work has taken place. Also, Narratives are recorded in the ECH. An ECH is always linked to Equipment.

After the ECH has been completed, it should be reviewed and Final Approved. Note: The ECHs which are in Draft and have no indicator, or a green or orange indicator can be approved in bulk. ECHs with a red indicator should be investigated before the Final Approval. See Bulk Approving PLSS ECHs.

PLSS ECHs differ from standard ECHs in the fact that Anomalies can be created from the ECH. Otherwise they are aligned with the standard IMS ECH.
