The Home Tab > Input panel contains all of the input commands necessary to define a TANK job. Each command defines a type of data.

Tank Data Input Menu

General Tank Data

Opens the General Tank Data dialog box. Data must be provided on this dialog box for every tank analyzed. This information consists of the diameter, the number of courses, the course height, course thickness, course material, fluid depth, fluid specific gravity, temperature, pressure, external loads, and the needed code.

Seismic Data Specifications

Opens the Seismic Data Specifications dialog box where you can describe the seismic parameters associated with the tank location. The computations that use this data are found in API-650 Appendix E or API-620 Appendix L. This is dialog box is an optional input, depending on the tank.

Nozzle Stiffness ICON Nozzle Stiffnesses

Opens the Nozzle Stiffness dialog box, which allows you to specify up to fifteen low nozzles on the tank. The computations that use this data are found in API-650 Appendix P. This dialog box is an optional input, depending on the tank.

External Pressure ICON External Pressure

Opens the Appendix V External Pressure dialog box where you can enter data that determines the external pressure capacity of the tank.

Inspection Data ICON Inspection Data

Opens the API-653 Service Measurement Data dialog box.

API 579 Calculation API 579 Calculations

Opens the API-579 Flaw/Damage Input/Analysis dialog where you can define a flaw on the tank.

Roof Specifications ICON Roof Specifications

Opens the Roof Specification Parameters dialog box where you can enter roof descriptive parameters. The computations that use this data are found in API-650 Appendix F and in the text by Brownell & Young. This dialog box is an optional input, depending on the tank.

Grillage Review

Opens the Grillage Review dialog box where you can specify the grillage parameters. The specifics of this computation are found in API-650 Appendix I, Section I.7. This dialog box is an optional input, depending on the tank.

Cycle Life

Opens the Appendix M Cycle Life Data specification used in the procedures outlined in API-650 Appendix M to determine the allowed number of “fill-empty” cycles the tank can undergo without a detailed stress analysis. This dialog is an optional input, depending on the tank.

Shell Settlement ICON Shell Settlement Data

Opens the Shell Settlement Data dialog box used in the procedures outlined in API-653 Appendix B to determine the maximum and allowed out-of-plane settlement of the tank shell. This dialog box is an optional input, depending on the tank.

Venting Requirements ICON Venting Requirements

Opens the API-2000 Venting Data dialog box used to determine the necessary venting for in-breathing, out-breathing, and fire.
