Introduction: An Industrial Safety Challenge

With custom-engineered FRP grating and adjustable pedestal technology, FRP Engineering transformed an environmental hazard into a secure and efficient workspace at a BHP Pilbara site.

Mining sites like BHPs in the Pilbara face unique safety challenges due to constant exposure to environmental factors, heavy equipment, and high traffic. In October 2024, BHP engaged FRP Engineering to resolve significant hazards in a transformer bund at one of its sites in the Pilbara. Over time, the bund had been filled with blue metal fill, compromising its capacity and creating an uneven, hazardous work surface for personnel. The project’s goal was to replace the fill with a durable, level, and low-maintenance surface that would restore bund capacity while meeting BHP’s environmental and safety standards.

Project Scope and Objectives

The primary objectives were clear:

Restore Capacity: By replacing blue metal fill, FRP Engineering aimed to restore the transformer bund’s original capacity for environmental safety.
Ensure Worker Safety: The installation had to provide a stable, level surface to reduce the risk of worker injuries due to uneven terrain.
Enhance Environmental Compliance: BHP required a solution that aligned with environmental safety standards, reducing dust and contamination risks from the existing material.

Understanding the Challenges of Industrial Bunds

Bunds play a vital role in industrial safety, containing potential spills and preventing environmental harm. However, ensuring safe, navigable surfaces within bunded areas can be challenging. In the case of BHP’s bund, accumulated blue metal fill diminished containment capacity and introduced safety issues:

  • Reduced Capacity: The bund’s ability to hold spills was compromised, increasing environmental risk.
  • Surface Instability: The uneven fill posed slip hazards, making access difficult for workers.
  • High Maintenance: Blue metal fill generated dust and debris, requiring regular upkeep to maintain safety and compliance.

The Solution: Fiber Reinforced Polymer (FRP) Technology

To address the site’s challenges, FRP Engineering proposed a custom solution by replacing the blue metal fill with FRP grating and adjustable pedestals. Fiber Reinforced Polymer (FRP) is ideal for demanding environments due to its durability, corrosion resistance, and lightweight design.

Key Benefits of FRP Over Traditional Fill:

  1. Corrosion Resistance: FRP withstands chemicals and moisture better than metals.
  2. Lightweight and Durable: FRP grating is strong without added weight, simplifying installation.
  3. Low Maintenance: Its robust composition reduces maintenance time and cost.
  4. Customizable Stability: Adjustable pedestals create a level, secure surface, accommodating uneven ground effectively.

FRP Engineering’s Process: From Concept to Installation

  1. Precise Site Survey
    The first step involved surveying the bund area to take accurate measurements and determine load requirements. This survey was essential to customising the FRP grating panels and adjustable pedestals to fit the site’s specific needs, optimising both stability and safety.
  2. Prefabrication of FRP Components
    Using data from the survey, FRP Engineering prefabricated the grating panels and pedestals offsite. Prefabrication allowed for a highly accurate assembly and minimised the amount of onsite work needed, reducing disruptions and lowering installation costs.
  3. Installation with Adjustable Pedestals
    Upon delivery, the prefabricated FRP grating was assembled on-site, supported by adjustable pedestals. The pedestals allowed the team to level the grating quickly, even on the irregular ground, ensuring a stable, even surface across the bund area. Due to the lightweight nature of FRP, the materials were easy to transport and install, making for a smooth and efficient process.

Project Results: Meeting BHP’s Safety and Efficiency Goals

The new FRP installation provided immediate and long-term benefits for BHP at their Pilbara site:

  1. Restored Capacity and Environmental Safety
    With the blue metal fill removed and FRP grating in place, the bund area could once again meet environmental capacity standards. This containment capacity ensures that any potential leaks or spills remain within the designated area, preventing contamination.
  2. Improved Worker Safety and Operational Efficiency
    The FRP grating created a stable, level surface that significantly reduces the risk of slips, trips, and falls, ensuring a safer workspace for personnel. This stability allows workers to navigate the area with confidence, enhancing overall site productivity.
  3. Reduced Maintenance and LongevityThe FRP grating’s low-maintenance composition means fewer repairs and minimal upkeep, providing a long-term solution that reduces costs for BHP. In addition, the non-corrosive nature of FRP ensures that the new structure will hold up well against the demanding conditions at site.

The Long-Term Value of FRP for Industrial Applications

FRP’s advantages in industrial applications are clear, especially where environmental safety and worker protection are critical. Unlike traditional materials like steel and concrete, FRP provides a highly adaptable and cost-effective solution with a significantly lower environmental impact. This combination of durability, safety, and sustainability makes FRP an ideal choice for industries aiming to improve safety and reduce long-term costs.

Why Choose FRP Over Steel and Concrete?

  1. Enhanced Durability: FRP is highly resistant to environmental wear, chemicals, and moisture, which are common at industrial sites.
  2. Improved Cost-Efficiency: Although FRP may involve a higher initial investment, its low maintenance requirements and long lifespan deliver significant cost savings over time.
  3. Ease of Installation: Lightweight and adaptable, FRP is easier to handle than steel or concrete, allowing for quicker, less labour-intensive installations.

Looking Ahead: Future Applications for FRP at BHP Sites

The success of this project has set a precedent for using FRP in similar applications at other BHP locations. As BHP continues to prioritise environmental compliance and worker safety, FRP Engineering’s solutions offer a practical and sustainable approach to infrastructure upgrades across the company’s network.

Conclusion: A Safe and Sustainable Solution for BHP

FRP Engineering’s solution for the site is a prime example of how innovative materials can enhance industrial safety and efficiency. By replacing traditional fill with custom-designed FRP grating and pedestals, FRP Engineering not only restored the bund’s capacity but also improved safety and reduced long-term costs. As industries increasingly seek durable, low-maintenance solutions, FRP stands out as a reliable choice that supports safety and environmental goals alike.
