API-653 Hydro Waiver Brochure 1
Reconstruction and major repairs to aboveground petroleum product storage tanks require a full hydrostatic test before continued service. Performing this test can be costly, time-consuming, and often logistically challenging. Recognizing this, Section 12.3 of API 653 allows for exemptions to the hydrostatic test when certain criteria are met. One of these criteria is to perform a Fitness-For-Service (FFS) Assessment per API 579-1/ASME FFS-1.
Kiefner provides this expertise, including rigorous Level III Assessments utilizing proprietary FEA software. Just a few of the assessments Kiefner performs are:
- Wall Thinning (Parts 4, 5, and 6),
- Brittle Fracture, Crack-Like Flaw (Parts 3 and 9), and
- Distortion, Out of Roundness (Part 8).
Kiefner routinely performs this service for several US and Canadian operators, allowing for significant cost reductions and the safe continued operation of your storage tanks.
