Project Overview:
The Mt Isa Compressor Station serves as the Queensland terminus of the Northern Gas Pipeline (NGP), a 623 km pipeline connecting gas networks in the Northern Territory and Queensland. Altrad (formerly Valmec) was contracted for the civil, structural, mechanical, piping (SMP), and electrical and instrumentation (E&I) scopes, delivering an integrated solution that minimised interface challenges and ensured seamless project delivery.
Scope:
Altrad’s scope of work included:
- Procurement and installation of concrete foundations for compressors, pipe racks, and associated equipment.
- SMP works, including onsite fabrication, non-destructive testing (NDT), hydrotesting of pipework, and compressor unit landing and grouting.
- Procurement and installation of electrical materials, including cabling, cable support structures, and consumables.
- Support for the client’s commissioning team, including pre-commissioning and assistance through to the introduction of gas.
Outcomes:
- Successfully completed the compressor station construction, aligning with Jemena’s project schedule and operational requirements.
- Delivered significant cost savings through a unified mobilisation approach for civil, SMP, and E&I scopes.
- Remote Location: Addressed logistical challenges through careful planning and robust resource management for the central Queensland site.
- Hot Weather: Implemented the Altrad Hot Weather Policy to ensure worker safety and maintain productivity during extreme summer temperatures.
- Multi-Disciplinary Scope: Leveraged Altrad’s integrated capabilities to eliminate interface challenges between civil, SMP, and E&I works, providing cost and efficiency benefits to the client.
- Enhanced local engagement by collaborating with Traditional Owner groups and implementing a Local Content Plan to maximize Indigenous participation.
- Reinforced Altrad’s reputation for excellence in delivering large-scale, remote gas infrastructure projects.
