Gas Chemical Complex

The manufacturing plant will produce polyethylene and polypropylene of various trademarks from ethane, propane and butane​. The production capacity of the complex is 2.7 million tons of the ready products per year. The construction has already started in August, 2020 with a planned commissioning date in 2027. It is assumed that the enterprise s expected to become one of the largest base polymer production plants in the world.

Among the 40 structural steel detailers tasked with designing various structures for the gas chemical complex, ENECA was one of only three companies that managed to handle the extensive workload within a remarkably short timeframe.

Project Highlights:

• Steel: Over 14,450 tons.

Key Parameters of Facilities:

• Plan Dimensions: 28.5 x 26.0 m
• Building Height: 93.5 m
• Weight of Main Structures: 1,710 tons
• Number of Individual Parts: 11,097
• Number of Original Assemblies: 7,309
• Number of GA and Erection Drawings: 72
• Number of Connections: Over 12,000
• Number of Specialists Involved: 13
• Project Development Time: 3 months

Project Development Stages:

1. Initial Data Collection and 3D Model Preparation:

   • Detect and correct system errors.
   • Check the geometry of the 3D frame model.
   • Verify and adjust model attributes.
   • Utilize the AutoConnection plugin.
   • Upload the model to ModelSharing.

2. Modeling of Connections and Secondary Elements:

   • Edit connections with complex configurations.
   • Model ladders, railings, and gratings.
   • Use approaches such as:
     • Individual modeling of each element.
     • Utilizing standard Tekla components and Tekla Warehouse plugins.
     • Implementing parametric user components.
     • Leveraging the AutoConnection solution.
   • Remarkably, all 12,000 connections were added in just 2 hours due to automation and the parametric component base.

3. 3D Model Checks and Drawing Preparation:

   • Conduct collision checks for individual parts and fasteners.
   • Perform completeness checks.
   • Verify attributes for parts and assemblies.
   • Approaches included:
     • Each specialist controls their part of the model and monitors checklist points.
     • Use of interactive reports and Tekla Organizer.
     • Employing Clash Check Manager to identify issues.
   • Drawings developed include:
     • Single part drawings.
     • Assembly drawings.
     • General arrangement drawings.

4. Final Document Development and Submission:

   • Preliminary export of documents for internal review.
   • Visual and automated verification of documents.
   • Final export and submission to the client.
   • Quality checks conducted by:
     • Document developers (design engineers).
     • Team leaders or senior specialists.
     • Department heads.
   • Automated quality checks using TEKLA Structures tools.

This comprehensive approach ensures the project is executed efficiently, meeting all quality standards and client expectations.
