Creating Digital Twins of Industrial Plants

What Is an Industrial Digital Twin?

An industrial digital twin is a highly accurate digital representation of a physical plant, facility, or asset. It combines real-world measurements, engineering models, and operational data into a virtual environment where engineers can analyse, simulate, and plan improvements before making changes in the real world.

For industries such as mining, processing plants, refineries, and manufacturing, digital twins allow engineering teams to visualise complex systems and understand how equipment, structures, and services interact.

At Hamilton By Design, digital twins are typically created by combining engineering-grade 3D laser scanning, point cloud modelling, and CAD engineering workflows.

Why Industrial Plants Are Moving Toward Digital Twins

Industrial sites are often built and modified over decades. Drawings can become outdated, and documentation may not reflect the current state of the plant.

An industrial digital twin solves this problem by providing an accurate digital baseline of the facility.

Key benefits include:

Improved engineering planning and design accuracy
Reduced risk during plant upgrades
Better shutdown planning
Improved asset management and maintenance planning
Safer engineering decisions

Before any upgrade or modification, engineers must understand existing conditions. Technologies such as 3D laser scanning allow teams to capture the plant exactly as it exists.

How Digital Twins Are Created for Industrial Plants

Creating an industrial digital twin typically follows a structured workflow.

1. Engineering-Grade 3D Laser Scanning

The first step is capturing the plant using high-accuracy LiDAR or laser scanning systems. These scanners collect millions of measurement points, producing a point cloud that represents the physical environment.

Hamilton By Design provides engineering-grade scanning services across mining and industrial sites:

These scans capture:

Structural steel
Pipework systems
Mechanical equipment
Conveyors and material handling systems
Pumps and processing equipment
Access platforms and walkways

The result is a precise digital snapshot of the plant.

2. Point Cloud Processing

Once scanning is complete, the raw scan data is processed into a registered point cloud model.

This step involves:

Aligning multiple scans
Cleaning unwanted data
Verifying spatial accuracy
Preparing the data for engineering modelling

Hamilton By Design uses this workflow when converting scans into engineering models:

3. Engineering CAD Modelling

The processed point cloud is then used to develop engineering models in CAD platforms such as SolidWorks.

At this stage engineers can generate:

Mechanical layouts
Structural models
Pipework routing
Equipment positioning
Access and maintenance clearances

The digital twin becomes an engineering-ready model, not just a visual scan.

4. Integration With Engineering Projects

Once the digital twin is created, it becomes a core engineering tool used for:

Plant upgrades
Shutdown planning
Clash detection
Design validation
Construction planning

Many mining operations now rely on digital twins during major shutdowns and upgrades.

Practical Applications of Industrial Digital Twins

Digital twins are becoming common across mining and heavy industry because they reduce uncertainty in engineering projects.

Common use cases include:

Plant Upgrades

Engineers can design new equipment within the digital model before installation.

Equipment Replacement

Digital twins allow accurate measurement of existing assets when replacing pumps, conveyors, or tanks.

Brownfield Engineering

Older plants often have incomplete drawings. Digital twins provide accurate geometry for redesign.

Safety Planning

Access, maintenance space, and structural modifications can be analysed before construction begins.

Why Accuracy Matters

A digital twin is only useful if it reflects the plant accurately.

Engineering-grade scanning typically achieves millimetre-level accuracy, which allows engineers to confidently design new systems within existing infrastructure.

Without this level of accuracy, design clashes and construction delays become more likely.

The Future of Industrial Engineering

As industries adopt automation, remote operations, and predictive maintenance, digital twins are becoming central to engineering workflows.

They allow companies to:

Simulate plant modifications
Plan maintenance strategies
Visualise complex infrastructure
Improve collaboration between engineering teams

For companies managing large industrial assets, an industrial digital twin is quickly becoming a core engineering resource rather than an optional tool.
