Export project for a paper mill

What was done

During the project, S-Engineering specialists conducted an audit of four production areas and, based on its results, carried out a full scope of work on two of them.

• A Multi Motor Drive system was implemented – a complex solution consisting of 4 forming fabrics, 4 presses, 12 drying systems, 3 coating machines, 3 calenders, 12 threading systems, and a winding drive (a total of 116 drive units).
• Also implemented: a Roll Handling & Wrapping system.

The project included algorithm development, analysis and restoration of project documentation, and preparation of start-up and maintenance instructions for these areas.

• Safety systems Safety Speed Monitoring and Prevention of Unexpected Start were developed in compliance with international SIL 3 standards. These systems were missing from the original Chinese contractor, who left the site before project completion.
• Light-and-sound alarm systems and emergency stop systems were implemented.
  During the supervision stage, S-Engineering specialists independently restored both electrical and mechanical components.
• Custom software was developed to regulate paper web speed and tension.
• A full scope of work was completed on the roll transport and packaging area, and a warehouse accounting system was implemented based on Siemens software.
• Commissioning of both lines was carried out with complete verification of all connections and tuning of algorithms.
• Technological process stabilization was performed, ensuring the required quality indicators of the finished product.
• Full testing of the cardboard machine production line was completed, resulting in the first batch of three-layer coated cardboard.
