Procurement of Bulk Materials Handling
MachinesRichard Morgan
Director
• Stackers• Reclaimers• Stacker/Reclaimers• Shiploaders• In-pit systems
Equipment Types
• Custom designed• Long lead Time• High cost• Critical elements in supply chain
Features
Identifying requirements
• Configuration• Specification & procurement documents• Modularisation
Configuration
Specification
• Define design, material and quality requirements
• Ensure configuration and performance can be met realistically
• Good knowledge of the design standards• Industry experts should be consulted to
ensure that problems are not repeated• Operators and maintainers should review
• Common practice for shiploaders • Now possible for land based machines such as
stackers and reclaimers • Considerable savings in onsite labour. • Allows procurement from overseas where
costs are lower than in Australia. • Include transport load cases and sea
fastenings
Modularisation
Type of contract
• Design and Construct (EPC) - Single Contract• Design and Supply – (Installation &
Commissioning Separate)• Design Contract – (Supply, Installation &
Commissioning Separate)
Challenges with overseas procurement• Design
– Design by Experienced OEM - Fabrication Overseas
– Design by new entrant OEM - Fabrication Overseas
Challenges with overseas procurement
• Standards• Materials Substitution• Fabrication
– Main Structure– Access– Machining– Protective Coatings– Trial Assembly
Challenges with overseas procurement
• Vendor Items• Electrical Installation• Commissioning
Overseas procurement - lessons• Detailed review of specifications pre award• Australian Standards discussed pre-award• Review of the 3D model is needed• Adequate translation resources needed • Access design considered throughout the
design phase, not at the end.• Supplier design 100% prior to placing orders • Constructability review of design
Effective quality control and supervision
• Design Phase– Effective Specification Key Dimensions properly thought out Interfaces Well Defined Machine Loads required by other designers– Owners Engineer Role– Design Audit
• AS 4324.1 Appendix K guidance for engagement of a design audit engineer
• Engage Design audit engineer before specification for machine is finalized
• Involve audit engineer in tender review
Design Audit
Effective quality control and supervision
• Fabrication Phase– Owners Engineer Role– Local Inspectors
Shipment, site erection and commissioning
• Modular Construction• Packing• Road Transport o/s• Shipment• Road Transport in Country• Erection/Installation Phase• Cut in
Shipment, site erection and commissioning
• Commissioning• Deconstruction
