Sappi Ngodwana Mill - Electrostatic Precipitator Upgrade (P3 & P4)

As part of Sappi Ngodwana Mill’s carbon reduction upgrade, this project involved the mechanical installation of two large electrostatic precipitators (P3 & P4). Over five months, the units were pre-assembled and commissioned in twelve sections to ensure seamless installation during the mill shutdown. The team dismantled 380,000 kg of existing steelwork and installed 530,000 kg of preassembled units using a 750-ton crane. Working 24 hours a day for 23 days, the team executed a complex installation with precision and efficiency. The upgraded systems now operate beyond design expectations, showcasing exceptional planning, technical skill, and quality execution.

Seriti New Denmark North Incline BMH Civil & Structural Works

Seriti’s New Denmark colliery shaft upgrade project was a strategic initiative undertaken as part of the New Denmark life of mine and the ongoing coal supply agreement to Eskom’s Tutuka power station. The scope encompassed both Greenfield and Brownfield activities, including underground (UG) and surface works, civil engineering, and SMPP (Structural, Mechanical, Piping, and Platework). Major components of the project included the extension of the North main conveyor by 500 metres, installation of a 1.2km underground inclined belt at 14 degrees feeding into a 6KT silo, as well as two feeders and an accelerator belt beneath the silo. Additionally, AMTEC constructed a 6km overland belt to channel material to a 12KT silo. The project was completed in 24 months, with a strong commitment to safety, highlighted by the achievement of zero LTI free hours.

Exxaro Matla Mine 2 NWA construction of underground conveyor infrastructure

As part of the Matla Mine 2 Northwest Access Project, AMTEC was selected to execute the complete construction and commissioning of the TC01 decline conveyor and its associated services. This installation constitutes a critical connection between underground mining levels, facilitating the efficient transfer of run-of-mine coal from the 4 Seam conveyor to the pre-existing 2 Seam system. Our scope encompassed full conveyor assembly and integration of essential water services.

The TC01 decline conveyor is engineered to perform in challenging underground conditions, and all aspects were constructed in adherence to project specifications and Matla’s operational requirements. Portable water for suppression is drawn from an established surface reservoir and supplied underground via a shared distribution line servicing both potable water stations and the fire hydrant network.

The successful delivery of this project demonstrates our proficiency in managing complex underground construction within a live mining environment. By maintaining rigorous project management standards, prioritising safety compliance, and fostering effective collaboration between ourselves and our client, we have provided Matla Mine 2 with a robust conveyor system supported by comprehensive safety and water management infrastructure. The completed installation enhances material flow efficiency, strengthens operational safety, and supports long-term client productivity by adding 15 to 20 years onto the planned life of mine.

Glencore Tweefontein Rail Load Out

The Glencore Tweefontein life of mine and underground coal reclamation project encompassed a turnkey SMPP (Structural, Mechanical, Piping, and Platework) development. The main scope included the fabrication and construction of a Rapid Rail Load Out bin, which allowed for loading a full train of 100 wagons—approximately 700 tons in under two hours. Additionally, the project involved constructing two material stackers, each with a capacity of around 400 tons. This initiative was designed to optimise coal handling and streamline logistics for coal transport, contributing to the overall efficiency and productivity of the mining operation.

BHP Middelburg Water plant mechanicals

This construction project involved the installation and commissioning of extensive HDPE piping and mechanical infrastructure across a large industrial plant environment. The scope included the fabrication and installation of more than 12 kilometres of in-plant HDPE piping, and 5 kilometres of overland HDPE piping. Pipe diameters ranged from 25mm to 630mm, requiring specialized handling and welding capacity supported by 7 HDPE welding units.

The project also included significant structural works, such as fabrication of 25 tonnes of pipe supports, and the installation of more than 150 mechanical components and assemblies. Major infrastructure elements included the erection of two 375-ton limestone storage silos.

To manage the complexity and multiple work fronts, a full construction management team was deployed, with responsibilities divided across six area supervisors. Workforce levels peaked at 80+ personnel on site, ensuring efficient progress and adherence to schedule.

Sierre Leone Gangama Structural, Mechanical and Piping project

The Sierra Rutile Gangama Plant Project marked a significant milestone as AMTEC’s largest offshore project to date. As part of Sierra Rutile’s initiative to extend the life of their mine, the project involved the construction of a 500-ton-per-hour plant. The turnkey SMPP (Structural, Mechanical, Platework, and Piping) scope included the design and fabrication of all materials in South Africa, which were then shipped to Sierra Leone. Once in Sierra Leone, the materials were loaded onto a barge and transported via a local canal to the mine’s off-loading area, where a stiff leg crane facilitated unloading. The project scope covered the development of the front end, construction of a spiral plant, the construction of an 800-metre overland conveyor and involved over 3 kilometres of in-plant HDPE piping. In total, approximately 850 tons of equipment and around 350 shipping containers were managed and delivered to site for this major undertaking. The efficient coordination ensured that all required resources arrived on site, enabling the completion of the project regardless of geographical constraints.
