our approach
A plant that is well designed and properly commissioned still starts to slip once nobody is watching its performance. Instruments drift, failures arrive without warning, shift logs record stoppages that nobody analyses, and safety functions fall behind their proof-test schedule. None of it shows up as a single crisis. It shows up as lost production, one unplanned stop at a time.
We treat performance management as its own discipline, not an afterthought to commissioning. That means predictive maintenance tuned to your equipment, downtime data your team can act on, instrumentation you can trust, and the functional safety and OT security work that keeps a live plant safe to run.
It is also why the work tends to grow. Ok Tedi’s predictive maintenance program started with ten assets and expanded by a further 38 after its first year, and an instrumentation audit at Wodgina became an ongoing roadmap of reliability improvements.
WHAT WE DEVILVER
From loop-level stability to plantwide advanced control and the data platform that ties it together.
01 – assset performance management
When maintenance is reactive, the first sign of a problem is often the breakdown itself. We implement asset performance management that moves maintenance from repair to prediction, using the condition data your plant already produces. As an official Aspen Mtell partner, we build and tune machine learning agents against your equipment’s own sensor data and failure history, so the system flags genuine early degradation rather than adding noise to an already busy alarm list.
What this covers:
02 – donwtime monitoring
Handwritten shift logs and spreadsheets will tell you a machine stopped. They rarely tell you, consistently, why it stopped, for how long, or whether it was the same fault as last month. As RtTech’s delivery partner, we implement RtDuet downtime and OEE tracking on your existing AVEVA PI infrastructure, standardising reason codes and time usage models so every stoppage is captured the same way and reported automatically.
What this covers:
03 – E&I engineering
When instruments drift and P&IDs no longer match the plant, every decision downstream rests on guesswork. Our electrical and instrumentation engineers audit what is installed, bring documentation back to as-built, and fix, calibrate or replace the field devices your control system depends on. At Mineral Resources’ Wodgina lithium operation, that meant auditing 2,800 instruments from coarse ore reclaim through to tailings and drafting 143 redline P&IDs to as-built.
What this includes:
04 – fuctional safety
A safety function that passed validation at commissioning doesn’t stay compliant by itself. Proof testing, modifications and ageing hardware all change the picture over time. Our functional safety engineers support the operate-and-maintain end of the lifecycle on stackers, reclaimers, shiploaders, car dumpers and conveyors, from proof-test procedures and change management to retrofitting legacy machines with SIL-rated components. The team includes more than 20 engineers trained in exida’s FSE-110 machine functional safety program and several TÜV-certified specialists
What this includes:
05 – Operations support & cybersecurity
Handover is where support gaps show up. Site teams inherit PLC logic, historians, virtual servers and dashboards they didn’t configure, and a fault at 2am can’t wait for someone to fly in. We provide remote, 24/7 and onsite support across control systems, infrastructure, plant data and MPA software, including systems we didn’t build. Secure VPN access, offsite backups and preventative checks keep a live control network recoverable, and agreements come with clear response times and monthly reporting.
What this includes:
06 – digital transformation & mining 4.0
Digital transformation stalls when technology arrives before strategy, or when the people expected to use it were never brought along. Our Mining 4.0 consultants start with a digital maturity assessment, then build roadmaps that connect automation, analytics and IIoT to real operational goals, with change leadership built in from the start. Between 2018 and 2020, that approach shaped Ok Tedi’s automation roadmap. On the shift floor, a 24/7 North American gold operation replaced whiteboards with TCard and cut downtime linked to missed tasks by around 30%
What this includes:
proof, not promises
Ok Tedi selected Aspen Mtell in 2023 and Mipac led the implementation, starting in May 2024 with ten critical assets in the crushing and grinding circuit. After twelve months the system was identifying degradation ahead of failure and several incidents had been avoided. In June 2025, OTML ordered a rollout to a further 38 assets across flotation and power generation.
●Ok Tedi · Papua New Guinea
Glencore’s Kamoto Copper Company was recording equipment downtime on handwritten logs and re-keying it into Excel. Mipac delivered RtDuet remotely during COVID-19, configuring more than 30 machine centres across the concentrator and refinery in English and French, standardised to Glencore’s global time usage model.
●Glencore · Kamoto Copper Company,Democratic Republic of the Congo
Wodgina’s three-train lithium plant had no as-built P&IDs and uncertain instrument performance. Mipac audited 2,800 instruments, brought 143 P&IDs back to as-built and set a roadmap that led to instrument and valve replacements, calibration training and new flotation cameras.
