The Rio Tinto Alcan Yarwun Refinery (RTAY) is undertaking a CAPEX project to upgrade the existing Hydrate Stockpile infrastructure in an effort to reduce contamination of the Hydrate Stockpile. The project focuses on the construction of a new stockpile pad, shed facility, transfer towers and associated conveyors to effectively convey hydrate between the plant and pad – ready for shipment via conveyor to the Fisherman’s Landing Wharf. 

Scope of Work: 

• Erect portal frames (70.5m L x 38m W x 24m H) and install an elevated walkway with conveyors and 2 monorails. 
• Build structural steelwork (23m H) for the North Transfer Tower with four working levels and conveyor tie-ins. 
• Construct the West Transfer Tower modularly (27.5m H, 7 levels) with conveyor tie-ins and a 20t surge bin. 
• Install a stairway across Export Conveyor (480CV10100). 
• Tie into the existing 470CV10010 belt; install new plough, headchute, and head end drive. 
• Install a 26m gantry for Cross Conveyor (480CV10070) and align mechanical components. 
• Install a 20m gantry for Feed Conveyor (480CV10080) with a total length of 86m and add 3 mechanical ploughs. 
• Install and commission sprinkler and small-bore piping; tie in eyewashes and hose reels. 

 The project involves constructing 1 shed, 2 transfer towers, and tying into the existing plant, with approximately 715t of steelwork and mechanical installations completed.
