Shell Plumbness and Roundness Evaluation

The purpose of this study is to determine the tank shell out-of-roundness, locations of buckled areas, flat spots, and peaking and banding at weld joints. Shell distortion can be caused by many conditions, such as foundation settlement, over- or under-pressuring, high wind, poor shell fabrication, or various repair techniques or tank modifications.

Methodology The vertical shell profiles were obtained externally at equally spaced planes arround the circumference of the tank with measurements recorded at 6-inch intervals along each vertical profile. All measurements were recorded using an aoutomatic laser scanning surveying instrument, Lieca® 3D DISTO.

Plumbness Evaluation The maximum allowable out-of-plumbness for this tank is 4.86 inches in accordance with API Standard 653. The maximum calculated out-of-plumbness for this tank is 1.716 inches.

-The tank shell out-of-plumbness is within the limits of API Standard 653.

Roundness Evaluation The maximum allowable out-of-roundness at 1-foot shell height for this tank is 1.5 inches in accordance with API Standard 653. Evaluation of roundness at 1-foot shell height can only be accurately performed from inside the tank.

-The shell out-of-roundness at 1-foot was not evaluated.
