Pressure Equipment Engineering Services, Inc. has following capabilities in the area of Storage Tanks:

• Design, analysis and rerating of large Storage Tanks based on API-650.

• Design, analysis and rerating of low pressure Storage Tanks based on API-  620.

• Calculations and recommendations for repairs, alterations or replacement of existing storage tanks and storage tank components per API-653.

• Re-rating of existing storage tanks for a new set of design parameters.

• Calculation of minimum retirement thickness values for existing storage tanks / storage tank components to maximize the remaining safe and useful life.

• Maximum fill height calculation for tanks where tank walls have corrosion or where higher than design density fluids are to be stored.

• Fitness-for-service evaluation of storage tanks with differential settlement of the tank bottoms. This includes edge settlement and internal bottom settlement / bulges.

• Fitness-for-service evaluation of Storage tanks to calculate MSOT (Minimum safe operating temperature) and address brittle fracture considerations.

• Fitness-for-service evaluation of tank roofs of Storage tanks (When roofs show signs of excessive deformation due to excessive loading e.g. snow loading) along with recommendations for repair.

• Fitness-for-service evaluations for storage tanks to assure the structural integrity of equipment for the intended design parameters and to offer life extension considerations.

• Failure Analysis to identify the root cause of failure for the failed storage tanks or storage tank components.

• Finite Element Analysis for storage tanks or storage tank components.

• Storage tank certification, calculations and rating / re-rating for storage tanks that do not contain sufficient design information in their files.

• Analysis to assure Mechanical Integrity of storage tanks for following type of flaws:  Generalized corrosion, Localized corrosion / Thinning, Blisters, Laminations, Bulges, Gouges, Dents, Cracks etc.

Here are some examples of Storage Tank Design / Analysis performed by Pressure Equipment Engineering Services, Inc.
