Introduction
The design requirements of API Standard 650 will be explained and their application demonstrated through example problems. Material, fabrication, and erection requirements documentation will also be reviewed. The candidates will gain knowledge for the design of safe and economical storage tanks used in the petroleum and chemical industries. In addition to a general review of API Standard 650, an introduction to tank inspection and evaluation in conformance with API Standard 653 will be included. This course delves into the very complex world of large field erected fuel storage tanks built under API Standard 650. This is a technical design class for aboveground closed and open-top welded steel storage tanks operated under atmospheric pressure reviewing: materials, design, fabrication, erection, and testing.
This course will not focus on specific size tanks for typical applications. Instead, it will go through the complete design process for preparing plans and specifications for any size tank for the storage of combustible and flammable liquids. The course is not limited to the major provisions of API Standard 650. It will also review in detail the entire document including its 18 separate appendices. These other critical sections involve topics from pontoon supported roofs and low-pressure tanks to some shop fabricated tanks and under bottom connections to the tank on grade.
Objectives
- Gain an understanding of the design and maintenance requirements of aboveground atmospheric storage tanks in accordance with API-650, API-653, and API-620 respectively
By the end of this course delegates will be able to:
Training Methodology
This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.
Who Should Attend?
Engineers, inspectors, technologists, and experienced operators with technology backgrounds who are involved in the construction, inspection, maintenance and repairs of tanks for safe operations in the plant.
