Gas Chemical Complex ​

SCOPE OF WORK:
  • 3D Modelling ​
  • Workshop and erection drawings (structural steel detailing).
About the project

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


Spread of all different facilities designed by ENECA is more than 14450 tons.


Of all 40 structural steel detailers who designed various structures for the gas chemical complex, ENECA was one of the three companies that managed to cope with such a great scope of work in an extremely short period of time, as well as the only one who eventually agreed and successfully completed the work on time.​

Parameters of one of the facilities​ design by ENECA are as follows:
Plan dimensions ​ - 28.5 х 26.0 m
​Height of the building - 93.50​ m​
Weight of the main structures - 1710 ​t
Amount of single parts - ​11,097
​Amount of original assemblies - ​7,309​
Amount of GA drawings, erection drawings ​ - 72
​Amount of connections ​> 12 000​
Amount of specialists​ - 13​
Project development timeline ​ - 3​ month

Project Development Stages
1) Initial data are obtained and a 3D model is prepared for the joint work​
  1. System errors are detected and eliminated​
  2. 3D rod model geometry is checked​
  3. 3D rod model attributes are checked and adjusted​
  4. AutoConnection Plugin is applied​
  5. The model is uploaded to ModelSharing​
2) Connections and secondary elements are modelled​
  1. Connections of complex configuration are edited​
  2. Modelling of ladders and railings​
  3. Modelling of gratings​

Approaches:​

  • Element-by-element modelling​
  • Use of standard Tekla components​
  • Use of Tekla Warehouse plugins​
  • Use of parametric user components​
  • Use of AutoConnection function

Due to the automation, availability of the parametric component base and use of AutoConnection function - all 12 000 connections were added in 2 hours!

  • Use of Tekla Warehouse plugins​
  • Use of parametric user components​
  • Use of AutoConnection function

Due to the automation, availability of the parametric component base and use of AutoConnection function - all 12 000 connections were added in 2 hours!
3) 3D model is checked for mistakes and the drawings are prepared for development​
  1. Check of single parts and fasteners drawings for collisions​
  2. Completeness check​
  3. Check of single parts and assemblies attributes​


Approaches:​

  • Each specialist controls​ the scope of work within his/her part of the model and observes the points summarised in check list​
  • Use of interactive reports​
  • Use of Tekla Organizer​
  • Use of standard Tekla tool - Clash Check Manager
Several assemblies in the assembly
  1. Development of single part drawings​
  2. Development of assembly drawings​
  3. Development of general arrangement drawings​

Approaches:​

  • Creation necessary settings for drawings​
  • Application of efficient methods for editing drawings​
  • Application of execution standards​
  • Cloning of drawings once executed​
  • Use of a prototype drawings catalogue​
  • Creation and filling of the library with cloning templates
4) Single part drawings, assembly drawings,​ general arrangement drawings are developed
4) Single part drawings, assembly drawings,​ general arrangement drawings are developed
  1. Development of single part drawings​
  2. Development of assembly drawings​
  3. Development of general arrangement drawings​

Approaches:​

  • Creation necessary settings for drawings​
  • Application of efficient methods for editing drawings​
  • Application of execution standards​
  • Cloning of drawings once executed​
  • Use of a prototype drawings catalogue​
  • Creation and filling of the library with cloning templates
  1. Preliminary export of documents for internal check​
  2. Visual and automated check of the documents​
  3. Final export of the documents and their submission to the Customer

Approaches:​

  • Quality check of the documents carried out directly by a developer (design engineer)​
  • Quality check of the documents carried out by a chief/lead specialist (team leader)​
  • Quality check of the documents carried out by the head of the department​
  • Quality assistance​
  • Automated check according to the algorithms set in the programming environment of TEKLA Structures
5) The documentation is checked and formed to be sent to the Customer​
WHAT RESULTS HAVE BEEN REACHED?​
  • 1
    The time limits for developing projects have been reduced by more than 2 times (due to a high degree of automation)​
  • 2
    The manhours for routine operations have been reduced thanks to the AutoConnection function​
  • 3
    The quality of 3D models and production documentation has been improved through the use of developed and tested parametric components, automation, development of drawings using prototype drawings and check of the documents at different levels​
  • 4
    The number of collisions of single parts, assemblies, fasteners has been minimised; the number of questions from manufacturers of metal structures has been reduced; the number of questions from construction and erection companies during the erection process has been reduced due to the automation and checks, since we eliminated all possible errors ​
