Desain Dan Analisis Kekuatan Storage Tank Kapasitas 10.000 KL Terhadap Wind Load, Seismic Load Dan Hydrostatic Load

Abstract

A company engaged in the distribution of fuel oil located in the Tank Terminal area, South
Kalimantan, which is responsible for managing and distributing fuel oil supplies plans to build a fuel
oil storage tank of up to 10,000 KL using ASTM A36 carbon steel material. The tank design refers to
the API 650 standard, 13th edition, 2020, including the calculation of minimum thickness for the shell,
bottom, annular bottom, roof, manhole, and nozzle. The Indonesian National Standard (SNI) is used
for earthquake and wind load calculations. The design is modeled with software and also finite element
method analysis using Ansys software to determine the strength of the tank. Based on the calculation
of the one-leg method, the minimum thickness for layer 1 is 16 mm, layer 2 is 15 mm, layer 3 is 14 mm,
and layer 4 is 12 mm, layer 5 is 10 mm, layers 6 and 7 are 8 mm, layer 8 is 6 mm. The minimum plate
thickness for the bottom is 8 mm, the circular bottom is 8 mm, and the roof is 7 mm. 3D modeling using
software covers several parts of the tank design, starting from the bottom plate, circular bottom plate,
shell, and roof. The modeling results can be used to simulate stress analysis using ANSYS software to
obtain Von Mises values and deformation. Furthermore, this modeling can be used to simulate stress
analysis using ANSYS software to determine Von Mises values and deformation.
