    Qinghai Magnesium Smelter – Dehydration Facility

    Golmud, Qinghai, China

Project Summary

Qinghai Salt Lake Industry Corporation appointed Hatch to perform the first phase of detailed engineering and provide procurement support for the AUD 4-5 billion Qinghai Magnesium Smelter Dehydration Facility under construction in Qinghai Province, China. Hatch partnered with Shenyang Aluminum and Magnesium Design Institute for completion of detailed engineering and handover to the construction contractor.

Based on an existing plant purchased and relocated from Canada, the facility required significant design modifications. Bentley PlantSpace provided 3D modeling applications for the plant layout, including piping, equipment, and cable-tray layout. Using Bentley PlantSpace P&ID synced with Bentley Data Manager created a master engineering database for 248 P&IDs. The data-centric design environment significantly reduced time required for data verification.

When pipe material class specifications were converted from ASME to Chinese GB, the 3D model automatically regenerated, avoiding an 80% remodel and significant delay. By using a data-centric design environment, Hatch significantly reduced the time required for verification of data, allowing the distributed project team to focus on delivering a quality project, on time and budget. Worksharing and collaboration on a 24/7 basis enabled the team to achieve project goals.

In addition to the PlantSpace Design Series, Hatch used ProjectWise to link offices on three continents, Bentley Structural for the building concrete structure and steel superstructure, Bentley AutoPIPE for piping stress ISOs, Bentley Navigator for 3D visualization among non-designer team members, and MicroStation for modeling and 2D drawing production. Weekly sharing of i-models allowed distant team members to participate in interactive design reviews.
  • The dehydration facility was purchased from Canada, where the existing plant was disassembled and shipped to China.
  • The facility is a 70-meter-high concrete and steel structure occupying 18,000 square meters.
  • More than 1,500 items of equipment are connected to 75 kilometers of piping.
  • 85 team members were distributed among offices in Canada, Australia, and China.
  • Bentley PlantSpace produced 248 P&IDs and all 3D models, which were converted automatically from ASME to Chinese GB.
