A tank maintenance and integrity evaluation course can only be effective if it also considers tank design requirements. Recognizing the primary features of these tanks and understanding how they are designed provide the information needed to better understand their maintenance requirements. The first part of this course focuses on atmospheric storage tank design requirements in accordance with API 650. Once the basics of storage tank design have been established, the course will turn to maintenance requirements in accordance with API 653. The course includes slides of actual installations, sample problems, and classroom exercises to illustrate specific points and give the candidates the opportunity to practice application of the topics discussed. It is recommended that the candidates bring copies of API 650 and API 653 to the course. The candidates are asked to bring a hand-held calculator to the course.

By the end of this course delegates will be able to:

• Gain an understanding of the design and maintenance requirements of aboveground atmospheric storage tanks in accordance with API-650 and API-653 respectively

Individuals who have engineering, inspection, maintenance, and management responsibility related to aboveground atmospheric storage tanks that store hydrocarbon liquids, individuals who have engineering, inspection, maintenance and management responsibility related to aboveground atmospheric storage tanks that store hydrocarbon liquids
