The platform can be installed on the cylindrical parts of vessel casing, as well as on the supporting skirt of the column.
Fig. 1. Service platform of vertical vessel
A variant of the platform for the horizontal vessel is a rectangular flooring, optionally fenced with railings. Weight of the platform and its wind load are applied to the horizontal shell in a given number of points (parameter “Number of rows of supporting lugs”).

Combination of railings on the four sides can be arbitrary, which makes it possible to form a multi-layer floor from several platforms.

The specific weight Ga is assigned according to SP 20.13330 and includes the load from the material, snow, equipment, people, etc. This load is considered to be evenly distributed over the sector of the site and is used in calculations (when determining the natural period, load on the supporting shell, etc.).
The parameter "Weight of material" is not used in strength calculations and is required only for calculating material consumption.
