The design and stress analysis of a 10.000 barrel fixed roof crude oil storage tank

Abstract

Improving facility such as storage tank for crude oil distribution is essential as a means to preserve the running of the production process. Many industries, especially in the crude oil industry, carbon steel material of tank become the widely used material. This recent study intended to design the crude oil storage tank using the API 650 standard. Fixed Cone Roof Tanks with 10,000 barrels of capacity using A36 material was chosen as the storage tanks. Based on the manual calculation, it was obtained that the thickness of the actual shell plate was 6 mm. The result of the calculation also determined that the bottom plate and annular bottom had each 9 mm for the thickness and the roof plate had 6 mm of thickness. While the highest stress distribution, which was still under the allowable stress occurred on the bottom part. The analysis of storage tanks also determined that the stress due to static stress, circumferential stress, and longitudinal stress were under the allowable stress of the material.
