The master's thesis closly explains how to work in the computer tool for the 3D piping design AVEVA Everything3DTM (AVEVA E3D Design), together with its structure, modules and elements. A concrete example of tracing of piping is shown „Connecting piping: Turbine – Steam distributor 2“ in a boiler plant, the construction of the necessary hangers, supports according to ROHR2 calculations (Computer-Aided Engineering system for static and dynamic stress analysis of the pipeline and its components), the construction of the necessary substructure and the production of technical documentation. When the tracing of piping is finished and all the equipment installed according to P&ID, hangers and supports are installed according to the ROHR2 calculation, the necessary substructure for hangers and supports is constructed, the substrates are prepared for the detailed design (3D piping model, pipe route isometric drawings, material specification, ROHR2 calculation and drawings of hangers and supports). According to the prepared substrates, a 2D detailed drawing of the piping, hangers and supports with their substructure and associated documentation (Covering sheet, WHTP, calculation sheet and material specification) is made. When the 2D detailed drawing is completed, reviewed and approved, it goes to the workshop for the production, after which it is transported and installed at the pre-arranged construction site.
