General Features |
- Calculations in English or Metric Units
|
|
Base Plates |
- Calculations for the following base plate types
- Base ring only
- Base ring with gussets only
- Base ring with centered anchor bolt
- Base ring with gussets and continuous compression ring
- Base ring with gussets and compression plate (anchor bolt chair)
|
|
Skirts |
-
Calculations for the following skirt types
- Conical (minor opening on top & major opening at base)
- Cylindrical
- Both can be designed in multiple sections of different geometries and materials
|
|
First Natural Period of Vibration
(FNPV) |
- Calculations
- Based on Rayleigh’s un-dampened beam method utilizing superposition
- Seismic shear force is calculated utilizing the FNPV and the included or user specified seismic data

|
Wind & Seismic |
- Codes Referenced
- ANSI/ASCE 7-88
- ASCE 7-93
- ASCE 7-95
- ASCE 7-98
- ASCE 7-02
- ASCE 7-05
- UBC 1991
- UBC 1994
- UBC 1997
- IBC 2000
- IBC 2003
- IBC 2006
- User defined data may be entered for specific regional statistics not included in the above Codes
- Calculations
- Seismic shear – See FNPV above
- Resultant forces and overturning moments are calculated between the elevations under consideration
- Forces may be calculated and evaluated separately or in various combinations
- Worst case directions are used for each considered elevation to determine stresses

|
Loadings & Attachments |
- General
- Stresses due to attachments applied at different elevations, such as piping, pumps, or platforms, are considered for your vessel
- Liquid, insulation, packing, and wind loadings due to increased wind diameter loadings can also be considered.
- Easy entry – just enter your load with the starting & ending load elevations
- Test conditions
- Multiple conditions can be tested with a single setup
- You may even specify if your attachments, insulation, or packing will be present during the hydro test

Reports |
-
A.P.V. has the most clear, concise, well thought out reports in the industry
- Calculations are shown in their original algebraic format
- Reports include the appropriate Code formulas with the proper design values inserted and results (great for inspectors, customers, & QC/QA personnel)
- Report sections can be re-ordered and added or removed from the report as needed (i.e. reviewing the nozzle report)
- Reports may be printed, viewed on screen, or save them as a PDF (for email, electronic storage, use on a secure intranet, etc.)
