1 INTRODUCTION
The purpose of this examination is to assess the dimensional compliance of the tank in according with the relevant
sections of API 650: Welded Steel Tanks for Oil Storage and API 653: Tank Inspection, Repair, Alteration, and
Reconstruction.

4 ANALYSIS
4.1 SHELL
The North Manway was used as the point of reference for shell analysis. All circumferential measurements are
distances from the North Manway along the shell in a counter-clockwise manner. All elevation measurements are
heights from the floor to shell weld at the North Manway.

Shell inner radius 66 ft 11.50 in
Shell tilt 0.03°

4.1.1 ALIGNMENT
Alignment analysis is used to assess deflections in the shell. It gives a good overview of the shell’s condition and is
a good indicator of plumbness and roundness, which are assessed independently in subsequent sections. Alignment
compares shell radii as measured from the best-fit center of the tank. The tolerances used are the 95% confidence
intervals of the shell radii. Positive values (red) indicate a deflection outwards while negative values (blue) indicate
a deflection inwards.

4.1.2 PLUMBNESS
The API allowable tolerance for deflection from plumb is 1.92" for a new tank of this height (API 650 Section 7.5.2
Plumbness). Positive values (red) indicate a slope outwards while negative values (blue) indicate a slow inwards.

4.1.3 ROUNDNESS
The API allowable tolerance for roundness at 1' is 0.75" for a new tank of this diameter (API 650 Section 7.5.3
Roundness). Positive values (red) indicate a deflection outwards while negative values (blue) indicate a deflection
inwards.

4.1.4 PEAKING
Peaking is horizontal discontinuities in roundness, typically occurring at vertical weld joints. The API allowable
tolerance for peaking is 0.50" for a new tank (API 650 Section 7.5.4 Local Deviations). Small areas identified near
the top and bottom of the shell are likely a result of structures affixed to the shell that cause discontinuities along its
surface.

4.1.5 BANDING
Banding is vertical discontinuities in flatness, typically occurring at horizontal weld joints. The API allowable
tolerance for banding is 0.50" for a new tank (API 650 Section 7.5.4 Local Deviations). Small areas identified near
the top and bottom of the shell are likely a result of structures affixed to the shell that cause discontinuities along its
surface.

distances from the North Manway along the shell in a counter-clockwise manner.

If the R2 value is less than 0.9 or if the shell settlement tolerance is exceeded, it is recommended to use the method
outlined in API 653 Section B.3.2.2. The API allowable tolerance for shell settlement using this method is 0.38"
(API 653 Section B.3.2.2 Permissible Out-of-plane Settlement).
