TANK incorporates the major considerations of API-650 Section 5 and several of the Appendices. These include:

  • Shell course thickness and fluid height computations according to either the variable point method or the one foot method.

  • Wind girder computations for the top and up to five intermediate girders.

  • Minimum metal temperature reporting.

  • Shell course thickness and fluid height computations according to Appendix A.

  • Seismic computations according to Appendix E.

  • Internal pressure considerations according to Appendix F.

  • Grillage computations according to Appendix I.

  • Material modifications due to temperature according to Appendix M.

  • Cycle Life computations according to Appendix M.

  • Nozzle flexibilities and limiting loads according to Appendix P, including the limiting load interaction diagrams.

  • Stainless Steel considerations according to Appendix S.

  • External pressure computations according to Appendix V.

  • Duplex Stainless Steel considerations according to Appendix X.

  • An alternate nozzle stiffness calculation routine according to PVP-1279.

  • Tank sizing/costing scratch-pad.

  • A Material Database editor.

TANK also incorporates the following considerations from API-620:

  • Shell course thickness computations according to Section 5.10.

  • Maximum compressive stress calculations according to Section 5.5.

  • Roof analysis according to Section 5.10.

  • Analysis of nozzles on the roof of a tank.

  • Vacuum analysis.

TANK also incorporates the following considerations from API-653:

  • Material modifications according to Section 2.3.

  • Shell Settlement evaluation according to Appendix B.

  • Retiring thicknesses and remaining corrosion allowance.

  • Corroded hydrotest case

  • Shell thickness evaluations using individual joint efficiencies and “L” locations

  • Bottom Plate minimum thickness determinations

  • Hydrotest heights

TANK can also design or analyze a supported cone roof according to the procedures outlined in Brownell & Young. TANK also incorporates venting computations from API-2000.

TANK relies extensively on data specified in the API codes. This includes the material data from Table 5.2, and digitized data from Appendix P. Other data tables have also been incorporated into the program where necessary.

Every effort is made to ensure that TANK is up to date with the current codes.
