Mechanical and piping engineering

Understanding the end-to-end supply chain ensures we can assess and design specifications for materials handling from concept to detailed level.

A dedicated Mechanical Engineering Group within Tetra Tech Proteus combines experience in mining, minerals processing, chemical plant and piping system design for diverse commodities from iron ore to rare earths.

Our understanding of the end-to-end supply chain ensures we can assess and design specifications for materials handling infrastructure from concept through to detailed level.

Both hydraulic design engineering and piping and pipeline design are core expertise at Tetra Tech Proteus so we can address our clients’ challenges and deliver optimal solutions.

Mechanical

Our solutions for materials handling projects have included rail car dumpers, conveyors and feeders, hoppers, transfer stations, sample stations, and screening facilities:

• Specifying, designing conveyor layouts; optimising feed-to-transfer points, mapping material flow with Discrete Element Method software​
• Conveyor capacity simulations give clients a tool to safely maximise capacity
• Process plant – siting and sizing, plant layout, equipment and piping.

Shutdown planning

Our shutdown engineers​ provide detailed planning services:

• Design and constructability reviews are tailored to each project
• Selecting contractors plus technical guidance throughout shutdown.​

Incident support 

• Dedicated incident experts respond to anything unforeseen.
• Sustaining capital project support​.
• Experienced personnel to support site-based projects.  ​

Pipeline design

Tailings disposal services include:

• Facility siting and sizing, and geotechnical evaluations
• Permitting, baseline and water balance studies
• Hydraulic engineering, slurry and water return pipeline design
• Construction drawings, bid packages plus construction management and quality assurance.
