  • Computations according to API-650 Section 3.11 for Wind Overturning Stability have been added.

  • Anchorage design/analysis according to API-650 Appendix E Section E.6 added.

  • Automatic generation of nozzle material modulus and expansion coefficient according to API-650 Appendix Table P-1 added.

  • The nozzle flexibility computations for API-650 Appendix P have been enhanced to interpolate between the L/2a=1.0 and L/2a=1.5 curves. Version 1.0 used one or the other set of curves, there was no interpolation between curves.

  • Nozzle flexibility analysis can optionally consider a reinforcing pad on the tank shell.

  • For API-653 analysis, an additional output table for “Retiring Thicknesses” and “Remaining Corrosion Allowances” has been added.

  • For API-653 runs, a configuration directive has been added to allow a “corroded” hydrotest case.

  • Several “network specific” enhancements have been made to the program. This includes changes to the file manager to recognize discontiguous disk drives, a network hardware lock, and a segregation of program and system files.

  • A new loader is available to provide diagnostic capabilities from the Main Menu.

  • The configuration program has been modified to track user changes, which enables the program to warn the user when an ESC is attempted without saving the data file.

  • A batch stream processor has been added to enable the processing of multiple jobs.

  • The input and output modules support a “pop-up” calculator for on-screen computations. The calculator supports the basic four math operations, trigonometric functions, squares, and square roots.

  • Several new configuration directives have been added. These new directives allow the specification of the default wind pressure for Section 3.11, and the setting of the default output report generation parameters.

  • An additional "English" units file is provided. This units file, MPH.FIL defines the wind speed in units of miles per hour.
