PASSAT and Shtutser-MKE

PASSAT is designed to calculate the strength and stability of vessels, process equipment, storage tanks and their components to assess load-bearing capacity during operation, testing and installation.

The software is used by more than 500 organizations in Russia, Ukraine, Kazakhstan, Belarus, China, Japan, Italy, the Czech Republic, Latvia, Bulgaria, Germany, Korea and the United States.

The software supports design, reconstruction, inspection and verification calculations of vessels, equipment and tanks in oil refining, chemical, petrochemical, gas, petroleum, nuclear and related industries

The PASSAT Columns module includes

• Determination of the lowest natural vibration period for column-type equipment with any number of elements;
• Calculation of forces on column-type equipment from wind loads (including wind resonance) and seismic effects;
• Adjustment of wind pressure by terrain category under SNiP 2.01.07-85;
• Strength and stability analysis of column-type equipment components;
• Support skirts for column-type equipment;
• Analysis of cylinder + cone supports with optional transition skirt;
• Automatic identification of the location and properties of the most critical support-skirt cross-section;
• Analysis of column-type equipment mounted on a pedestal. The pedestal may be a cylindrical or conical skirt or a steel structure;

FEM has become widely used for determining the strength and stiffness of tie-in joints. Unlike general-purpose finite element programs (ANSYS, NASTRAN, COSMOS, etc.), the developed program does not require specialized user training or significant time investment. Creation of a finite element breakdown and evaluation of the obtained stress-strain state (SSS) results for the tie-in zone are performed automatically.

SSS calculations are performed for both radial and oblique tie-ins into cylindrical and conical shells, elliptical, spherical, and flat heads, as well as pipelines. FEM calculations significantly expand the scope and accuracy of problem solutions.

The accuracy of strength calculations for vessels, apparatus, and pipelines at the junction is largely determined by the stiffness (compliance) of the tie-in. Typically, when calculating the strength of pipeline systems, the connection between the pipeline and the vessel (apparatus) is replaced by a dead support, which leads to excessive forces and stresses at the junction.
