CHPP Bidirectional Transfer (Engineering Design & Drafting)

Picture2.jpg

Project Description

Euler Engineering was engaged to provide detailed 3D modelling and drafting support for a Coal Handling and Preparation Plant (CHPP) bidirectional transfer upgrade within a live operating brownfield facility.
The project involved integrating a new bidirectional transfer system into existing platform steelwork and receiving belt frames that had evolved over time, with limited reliable as-built documentation. The works were scheduled for execution during a planned shutdown, requiring highly coordinated documentation to minimise downtime and site risk.
Engineering analysis, including FEA and DEM, was completed by others. Euler Engineering delivered the coordinated modelling and fabrication-ready documentation required for safe and efficient implementation.

Scope & Methodology

  • Site measure and coordination meeting to define constraints and shutdown sequencing

  • 3D modelling of existing platform steelwork and receiving belt frames

  • Integration of legacy infrastructure into a coordinated brownfield model

  • 3D modelling of the bidirectional transfer system from issued engineering drawings

  • Clash review and spatial coordination within a constrained plant envelope

  • Preparation of:

    • General Arrangement (GA) drawings for individual weldments

    • Full assembly GA drawings

    • Alumina tile layout drawings

    • Demolition drawings for existing components

    • Structural modification drawings

    • Detailed fabrication drawings including full Bill of Materials (BOM)

  • Supply of 2D DXF files for plasma / laser cutting

  • Documentation aligned with relevant Australian Standards including:

    • AS 4100 (Steel Structures)

    • AS/NZS 1554 (Structural Steel Welding)

    • AS 1657 (Access Systems)

    • AS 4024 (Machinery Safety – where applicable)

Outcome & Value

  • Delivered a fully coordinated 3D model of new and existing infrastructure

  • Reduced risk of clashes and site rework during shutdown

  • Streamlined demolition and modification works through clear documentation

  • Accelerated fabrication through workshop-ready drawings and DXF files

  • Supported safe and efficient execution within a constrained brownfield environment

Key Benefit

  • By combining accurate brownfield modelling with shutdown-focused documentation, Euler Engineering enabled the transfer upgrade to be executed efficiently, safely, and with minimal operational disruption
