A Deep Dive into Aboveground Storage Tank Settlement Evaluation

Feb 28, 2023

Foundational settlement, particularly non-uniform settlement, poses a significant threat to the integrity and operational reliability of aboveground storage tanks. In this article, Katelyn and Derek take a detailed look into at the most common API 653 evaluation methods to provide insight into the limitations and use of the various techniques and show the potential benefit of conducting a detailed analysis for differential shell settlement and bottom edge settlement.

Buckling Evaluation of Pressure Equipment and Plant Structures

Feb 28, 2023

In any industrial facility or plant, buckling poses a significant risk to nearly all components under compressive stress. Several finite element analysis (FEA) tools are used to solve complex buckling issues; however, without fully understanding the underlying mechanics and other relevant factors, the results can be misleading. In this article, Derek and Matthew review the methodology and limitations of the ASME VIII-1, ASME VIII-2, and AISC 360 standards for assessing buckling in beams, columns, steel structures, and pressure vessels.

Special Emphasis Areas in a Mechanical Integrity Program

Jun 29, 2021

Implementing a mechanical integrity (MI) program at a processing facility is essential for maintaining safe and reliable operations. In this article, Joel Andreani investigates an important subset of an MI program: special emphasis mechanical integrity (SEMI) programs.

Evaluating a Tank Fixed Roof Structural Failure

Apr 27, 2021

Aboveground storage tanks are susceptible to damage from many factors, including environmental loads, process upset conditions, strength reduction due to metal loss, tank settlement, or some combination thereof. This damage often manifests as buckling of the tank shell, which is thin relative to its large surface area.

Q&A: Structural Integrity Programs

Apr 27, 2021

Aging or deteriorating structures, foundations, and other infrastructure cost U.S. businesses billions of dollars each year. Problems with structures and foundations are often a result of design flaws, construction defects, deteriorating conditions, extreme environmental events, and/or changes in applied loads.
