Aboveground Storage Tanks (ASTs) are prominent plant components used for temporary storage of liquid or gas substances such as water, chemical products, and crude oil. Though tanks are comparatively simple assets, their individual parts all require a specific and intimate understanding to preserve safety and reliability, and they are still subject to the consequences of human error, integrity, and mechanical failures, and even natural disasters. In addition, storage tanks and their components are subject to codes and standards for design, inspection, maintenance, and repair, set in place by various regulatory agencies.
Common damage mechanisms of storage tanks include corrosion, shell bulging, cracking, and edge settlement. Additionally, leaks or ruptures can cause catastrophic damage affecting people and the environment. To comply with guidelines and maintain fitness-for-service (FFS), storage tanks may need to undergo acoustic emission testing (AET), structural assessments, seismic analysis, welding repair, or other valuations to address possible corrosion and metallurgy concerns. To explore these possibilities, you need a credible and proficient team dedicated to storage tank reliability.
