Engineering Re-Rating

Success Guaranteed

Our engineers re-rate pressure vessels and piping equipment in accordance with the codes of construction (ASME BPVC Sec. VIII Div. 1 & 2, ASME B31.3, ASME B16.5, ASME B16.9, ASME B16.11 etc.). Whether the purpose of re-rating is to accommodate process changes in the plant, or as a remediation effort in response to a Fitness-For-Service assessment, CANEIL can provide re-rate services that comply with both jurisdictional and client requirements. 

At a glance...

Engineering re-rates are a method for assessing the viability of changes in Maximum Allowable Working Pressure (MAWP), Operating Temperature limits, and geometric alterations to pressure vessel equipment and piping systems. The re-rate process consists of historical vessel data review, engineering analysis, and coordination with the Alberta Boiler Safety Association (ABSA) to secure design submission acceptance for the proposed operational change.

At CANEIL, our multi-ticketed engineers are able to retrieve pertinent equipment information through site visits to expedite the re-rate process. To meet jurisdictional requirements, we supplement our calculations with software analysis using PV Elite, COMPRESS, and Caesar II as required.

Upon ABSA Design Survey approval, CANEIL also offers services for the creation and shipment of nameplates for re-rated equipment. The following are example projects using supplementary software PV Elite and Caesar II.
