CADMATIC has been a key tool for the design of a Brazilian ground wood pulp plant, for cardboard producer Ibema Cia Brasileira de Papel S.A. (Ibema). In cooperation with ProjNet Engenharia e Sistemas (ProjNet), which provides consulting services to the pulp and paper industry, the plant was entirely designed in CADMATIC. The 3D model developed during the engineering phase will also be used inside the plant’s control room with the plant control system to assist with operation and maintenance.
ProjNet specializes in mechanical, piping, instrument, electrical and system design and uses CADMATIC as its principal design software. On the ground wood pulp plant project, the CADMATIC eBrowser functions as more than a project review tool, as it will also run in the DCS control station with the 3D model of the plant. The CADMATIC News team caught up with Ibema’s Maintenance Manager, Jorge S. Boabaid and Luiz Barbante, ProjNet’s Engineering Director, to talk about the project and how CADMATIC was used in the project design and implementation.
“The process could be designed thanks to CADMATIC's P&I Diagram solution. From simple valves to complex grinders and pulpers, it was possible to easily draw symbols, connect pipes, change data, revise and publish to suppliers and customers etc. After publishing the diagrams, it was simple to understand the process, exchange ideas and to optimize and continue the design. Since CADMATIC Diagram is directly linked to a SQL server database, it is possible to generate documentation such as equipment lists, specifications and attributes without the need to use software that is not common in an office software package”, says Mr Barbante.
According to Jorge S. Boabaid from Ibema, the visualization provided by the 3D model makes it easy to understand the whole plant structure and areas, even to people not familiar with 2D technical drawings and diagrams.
“The possibility to reach distant areas of the same plant in seconds and the use of only a single file is very advantageous. During a business or technical meeting it is really important to have the versatility of the 3D model to walk through different areas and acquire equipment data. The experience of visualizing the plant before it has been constructed is very valuable. Moreover, the possibility of opening the 3D model on any Windows Platform PC or notebook with Internet Explorer allows the exchange of the model and information in a way which would not have been possible otherwise”, Mr Boabaid explains.
“Once again, the capability of movement through the model is great for erection purposes. It is possible to check data, take measurements and visualize beforehand. The data stored in the database will also contain information regarding the erection date and start-up date, apart from the specifications, which simplifies management. It is also possible to check positioning, connections and the orientation of equipment, thereby avoiding mistakes and misunderstandings. It is much simpler to follow instructions given via a 3D model to be applied in a 3D environment, than instructions on many 2D drawings that can be confusing and lead to misinterpretation”, Mr Boabaid reveals.
“The eBrowser 3D model could also be a great tool for plant operation. By easily moving around the virtual facilities, it would be possible to see details without the necessity of going to the real facility. Many variables could easily be stored in the 3D model, such as the motor power or vessel volume and could also be retrieved, once again without the need to read documents or to go to the equipment to acquire such information. That is the benefit of having the 3D model on a PC in the Control Room. This is a trend which is set to continue in the coming years; the possibility to fully control the plant via a 3D model, with real-time information regarding processes such as pressure, flow and temperature, all in a single software application”, Mr Barbante points out.
“For maintenance purposes, having the real-time 3D model would also be extremely useful. It could contain all the information regarding the current state of the process, malfunctioning equipment, equipment that needs replacement parts, situations close to critical conditions, lack of material and many other variables and states”, Mr Boabaid adds.
