Australia's Mining Operations Run Better With the Right Consultant.

Maintenance problems in mining are expensive. KNA (Aust) Pty Ltd exists to fix them, with 36+ years of direct, hands-on experience across Australia's most complex industrial sites.

Kris Nahuys brings 36+ years of direct, hands-on experience in SAP Plant Maintenance, shutdown execution and maintenance systems improvement, deployed across some of Australia's most complex industrial sites. He has been subcontracted by Maintenance Systems Solutions (MSS) and Crystalise 360, two of Australia's leading specialist maintenance consultancies.

The Problems KNA Solves

Before you hire any consultant, you need to know they've solved your specific problem before.

Your shutdowns keep running over time and budget

Kris has planned and executed rolling 9-week and 13-week shutdown programs for FMG Iron Bridge and Covalent Lithium. He builds the plan, coordinates the people and materials, conducts pre and post-shutdown audits, and identifies shortfalls before they become delays.

Your SAP PM system is barely used or full of bad data

After 26 years working in SAP R/3, GSAP and SAP PM, Kris has configured, cleaned and trained teams on these systems at Vestas, Nyrstar, Dampier Salt and Geographe Enterprises. He has written ABAP queries and cleaned up 90-95% of erroneous GSAP data at a single site.

Your inventory is too high and you still can't find what you need

KNA has reduced inventory costs across multiple sites by maintaining master data lead times, correcting min/max levels, removing duplicate materials and linking parts to multiple alternative suppliers. At Dampier Salt, Kris catalogued over 600 critical spares to NATO Auslang standards.

You can't source a critical spare part during a shutdown

This is where most consultants stop. When a mine was one missing part away from care and maintenance, Kris located and procured the rare critical spare through his supplier network, preventing over $8 million in production loss.

Your team doesn't know how to use SAP properly

Kris has served as SAP Mentor and Trainer at Vestas Wind Systems and Nyrstar, formally appointed, not self-described. He has trained planners, schedulers and supply staff and built simplified maintenance manuals and site-based cheat sheets.

You need a remote planner for multiple sites simultaneously

At Vestas, Kris was remote planner for 250+ wind turbine generators across Tasmania and South Australia simultaneously, while also providing relief for site-based planner roles.

Services in Detail

What KNA Delivers

Six specialist service lines, all backed by direct site-level experience.

01

Maintenance Planning & Shutdown Execution

KNA plans and coordinates shutdowns of all scales, from major annual events to rolling modular programs. The approach is systematic: pre-shutdown audit, detailed work package preparation, labour and materials coordination, live execution support, and post-shutdown review.

  • Rolling 9-week and 13-week shutdown program management
  • Pre and post shutdown audits, gap identification before they become problems
  • Labour and materials coordination, internal and external
  • Work package preparation with attached drawings, standards and BOMs
  • Clients include: Covalent Lithium, Iron Bridge FMG, Nyrstar, Bluestone Mines
02

SAP PM Optimisation & Master Data Management

Most mining sites are running SAP at a fraction of its capability. KNA conducts a structured assessment, cleans the data, reconfigures the workflows and trains the team, leaving you with a system that actually works.

  • SAP R/3, GSAP, SAP PM, advanced configuration and cleanup
  • Master data: equipment records, BOMs, maintenance plans, measuring points
  • ABAP query development for custom reporting
  • End-user training and coaching, planners, schedulers, supply staff
  • SAP Mentor and Trainer formally appointed at Vestas and Nyrstar
03

Inventory & Warehouse Optimisation

Excess inventory is hidden cash. Missing critical spares are operational risk. KNA audits your warehouse, corrects lead times and min/max levels, removes duplicates, links parts to multiple suppliers.

  • Full warehouse and material storage audit
  • Master data lead time correction and min/max level review
  • Duplicate material identification and consolidation
  • Multi-supplier linking to reduce single-source risk
  • 600+ critical spares catalogued to NATO Auslang standards at Dampier Salt
04

Asset Criticality Assessment & Plant Audit

You can't maintain everything equally, but most sites try to. KNA audits your plant to identify, assess and catalogue assets by criticality and current condition, ensuring your maintenance strategy is focused where it matters most.

  • Full plant walkdown and asset identification
  • Criticality rating, function, redundancy, failure consequence
  • Current condition assessment and maintenance gap analysis
  • Cataloguing of required maintenance and operating spares
  • Maintenance strategy alignment to asset criticality
05

SAP Training, Coaching & Team Development

A system is only as good as the people using it. KNA provides structured, site-specific SAP training and ongoing coaching, built around how your team actually works, not generic classroom content.

  • SAP PM and MDM functional training for planners and schedulers
  • Warehouse activity and logistics best practice coaching
  • Site-based reference materials and cheat sheets
  • New planner onboarding, 3 planners trained at Vestas alone
  • SAP Mentor formally appointed at Vestas Wind Systems and Nyrstar Hobart
06

Remote & Multi-Site Planning Support

Not every engagement requires a full-time on-site presence. KNA provides effective remote planning support for single and multi-site operations, proven at scale with 250+ WTGs across two states simultaneously.

  • Remote SAP planning for single and multi-site operations
  • Relief planning during leave, transitions and peak workload
  • Work-from-home and hybrid engagement options
  • Proven across WA, SA, VIC, QLD & TAS operations concurrently
  • Clear communication with all stakeholders regardless of location
