Project Overview: A Game-Changer for Marine Construction

Project Start and Purpose

The Wheatstone project in Onslow, Western Australia, is one of the nation’s largest energy developments, requiring meticulous construction efforts. A key focus was the grouting of marine dolphins, essential for mooring vessels and constructing jetties and wharves. 

BAM Clough, the lead contractor, selected our plant for this critical task due to its reliability and custom design, ensuring precise and consistent results over the two-year project duration.

The Role of Batchcrete’s Twin Mix Grout Plant

Batchcrete’s Plant was custom-designed for the Wheatstone program, delivering 10–15 cubic meters of grout per hour to keep the project on schedule. Its mobile frame allowed for easy transport and setup, crucial for the remote Onslow site. This combination of mobility and high production capacity made the plant essential to the project’s success.

Custom Design and Rapid Fabrication

Batchcrete’s expertise in designing and fabricating specialized grout plants was fully on display with the Twin Mix Grout Plant. Understanding the unique challenges posed by the Wheatstone project, Batchcrete designed the plant from the ground up to meet the project’s specific requirements.

The design process was informed by years of experience and lessons learned from previous projects, ensuring that the plant would not only meet but exceed expectations. Despite the complexity of the design, Batchcrete managed to complete the fabrication of the plant in just six weeks—a testament to their commitment to delivering high-quality, tailored solutions on tight deadlines.

Inside the Grout Plant: Breaking Down the Key Components

The success of Batchcrete’s Plant lies in its carefully engineered components, each playing a critical role in the plant’s overall functionality. Let’s take a closer look at these key components and how they contribute to the plant’s impressive performance.

Gantry: The Backbone of Material Handling

The gantry system is one of the most important components of the grout plant, responsible for the efficient handling of materials. 

This motorized crane system is designed to pick up and drop bags of cement into the cement dispenser, ensuring a steady supply of materials for the mixing process. The gantry’s design emphasizes both precision and safety, critical in a high-stakes environment like marine construction. 

By automating the material handling process, the gantry reduces the risk of human error and ensures that the cement is delivered exactly where it’s needed when it’s needed. This efficiency in material handling is one of the key factors that allow the plant to maintain its high production capacity.

Cement Dispenser: Precision in Material Delivery

After the gantry drops the cement bags into the dispenser, internal blades split them open for efficient processing. The cement is then moved to the twin TTM mixers via a screw auger. 

The dispenser’s precision in delivering the correct quantities of cement is vital to maintaining the quality and consistency of the grout. This accuracy is especially critical in the Wheatstone program, where the durability of the marine dolphins hinges on the grout’s quality.

TTM Planetary Mixers: The Heart of Grout Mixing

The TTM Planetary Mixers, two 485L units, are the heart of the grout mixing station, designed for continuous grout production. Working in tandem, they ensure a steady flow of grout to the B100, critical for avoiding delays in the Wheatstone project. Their planetary design guarantees thorough mixing, producing high-quality grout that meets the project’s stringent standards.

B100 and Hydraulic Power Pack: Ensuring Continuous Grout Flow

Once the grout is mixed, it needs to be delivered to the site efficiently and without interruption. This is where the B100 and its hydraulic power pack come into play. The B100 pumps the grout using a stator and rotor, with the grout being transported through a 50mm hose to the site.

The hydraulic power pack ensures that the B100 operates smoothly, providing the necessary pressure to pump the grout over long distances if required. This system is designed to handle the continuous demands of the project, ensuring that the grout is delivered exactly where it’s needed, with minimal waste and maximum efficiency.

Control Box: The Central Command

Every complex system needs a central hub to coordinate its operations, and for the grout mixing station, that hub is the control box. The control box is the brain of the operation, managing and coordinating the various functions of the plant to ensure everything runs smoothly.

From the control box, operators can monitor the performance of the plant, make adjustments as needed, and ensure that all components are working in harmony. This centralized control is essential for maintaining the high levels of precision and efficiency required for the Wheatstone program, allowing operators to quickly respond to any issues that may arise.

Transforming Marine Construction: The impact of Batchcrete’s Plant

Grout mixing station has had a profound impact on the Wheatstone project, transforming the way marine construction is approached. By providing a reliable and efficient solution for grouting marine dolphins, the plant has played a critical role in the project’s success.
