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
