The blast furnace your grandfather started up in 1978 is being replaced by a machine your maintenance team has never seen. Direct Reduced Iron paired with an Electric Arc Furnace — the DRI-EAF route — is the pathway most European, North American, and Middle East steelmakers are betting on to hit net-zero targets, cut CO₂ by 90–95%, and stay ahead of the EU Carbon Border Adjustment Mechanism that moved into its implementation phase in January 2026. But the transition is not a control-system upgrade. It is an entirely new asset landscape — electrolyzers, hydrogen storage at 30–70 bar, a shaft furnace running on 90%+ H₂, an EAF transformer worth $5–15M with a 12–24 month replacement lead time — and a maintenance program built for coke, tuyeres, and hot blast stoves cannot manage any of it. Oxmaint is the maintenance management software purpose-built for steel plants, and it gives green-steel operations the CMMS backbone, asset hierarchy, PM cadence, and skills matrix that DRI-EAF operation actually requires from day one of commissioning. Start a free Oxmaint trial to configure the maintenance software for your DRI-EAF plant, or book a demo to see the Oxmaint CMMS mapped to your green-steel transition roadmap.

Why Now
The Transition Is No Longer a 2040 Question — and Your Software Has to Keep Up
Three forces converged in the last eighteen months to push DRI-EAF from strategy deck to construction site. Steel plants that treated green steel as a future problem are now retrofitting their maintenance software mid-project, and the ones without a plan are watching commissioning slip a quarter at a time. Oxmaint is the maintenance management software that gets ahead of these three drivers instead of chasing them.
-
Driver 01
Carbon Border Adjustment Mechanism
EU CBAM moved into implementation on January 1, 2026, ending the reporting-only transitional phase. Embedded emissions on imported steel now carry a real cost, and Oxmaint holds the audit-grade asset and energy ledger the CBAM regime requires from every producer selling into Europe.
-
Driver 02
EAF Capacity Growing 3× Faster
Electric arc furnace capacity is growing at roughly three times the rate of blast furnace investment, driven by scrap availability, carbon pricing, and reshoring in flat-steel markets. Oxmaint is the CMMS these new EAF-first plants use to manage heat-count PMs, inter-heat maintenance windows, and campaign shutdowns from commissioning.
-
Driver 03
Premium Green Steel Markets Live
Automotive and appliance buyers are paying a green premium today. HYBRIT delivered the first fossil-free steel to Volvo in 2021; H2 Green Steel and Stegra target commercial output at scale. Oxmaint gives producers the maintenance evidence base that green-premium buyers ask for during supplier qualification.
The Asset Landscape Shift
What Changes in the Plant — and What Your Maintenance Software Has to Manage
The single biggest miscalculation steel plants make in transition planning is treating DRI-EAF as a modification. It is not. Roughly 60% of the assets under maintenance on day one of a green plant did not exist on day one of the coal-based one. Everything below the coker, sinter plant, and blast furnace goes away. Everything above the electrolyzer, hydrogen storage, and DRI shaft furnace is new — and every one of those new assets has to be modelled inside your CMMS with the right hierarchy, PM library, and skill-tag routing. That is precisely what Oxmaint is built to do for steel operations.
Legacy · BF-BOF Route
Assets Retired
- Coke ovens and byproduct plant
- Sinter and pellet plants
- Blast furnace, tuyeres, hot blast stoves
- Stave cooling water plant
- Torpedo cars and hot metal transport
- Basic Oxygen Furnace and vessel
- BF gas cleaning and cast house
Green Steel · New Assets in Oxmaint
Assets Added
- Electrolyzer stacks (PEM or alkaline)
- Hydrogen storage (30–70 bar) and piping
- DRI shaft furnace (MIDREX-H2 / HYL Zero)
- Gas heater, top gas scrubber, recycle compressor
- Hot DRI transfer and briquetting
- EAF transformer, secondary bus, flex cables
- H₂ leak detection, SIL safety, ATEX zoning
Assets carrying across both routes — ladle metallurgy, continuous casting, hot and cold rolling, finishing — are only about 40% of the maintenance load. The other 60% is a plant nobody on your crew has run before, and Oxmaint gives that unfamiliar 60% a working home in the software from day one.
Four New Failure Modes
Failure Modes Your CMMS Software Has to Be Ready For
A veteran BF-BOF maintenance leader has an intuition for tuyere burnthrough, taphole erosion, and stave outlet ΔT. None of that intuition transfers cleanly to hydrogen-era steel. These are the four dominant new failure classes that will hit a green steel plant first — and the reason your maintenance management software needs a PM library, condition trending, and safety alerting that a generic CMMS simply does not carry. Oxmaint ships with all four modelled and ready for steel operations to configure.
-
01
Hydrogen Embrittlement
Hydrogen molecules — the smallest in existence — diffuse into carbon steel pipework, valve seats, and pressure vessels, degrading mechanical properties and initiating cracks that propagate under cyclic pressure. This mode is absent from every part of a BF-BOF plant.
Oxmaint handles: scheduled hydrogen-specific UT and acoustic emission PMs, austenitic-stainless material control on every asset record, quarterly leak surveys, escalation to certified crews
-
02
Electrolyzer Stack Degradation
Membrane fouling, catalyst dissolution, and current density drift steadily reduce hydrogen output per kWh. Stacks typically require replacement or refurbishment every 60,000–80,000 operating hours — a schedule that has to be planned against renewable electricity availability curves.
Oxmaint handles: per-cell voltage trending, water purity control checklists, catalyst mass balance, staged stack replacement planning inside the software
-
03
Metallization Loss in Shaft Furnace
Full-hydrogen reduction runs endothermically — meaning heat has to come from the process gas itself. If gas temperature drops or H₂ ratio shifts, metallization degree in the DRI drops below 90%, sending under-reduced iron to the EAF and destroying downstream productivity.
Oxmaint handles: continuous metallization sampling rounds, gas heater efficiency PMs, refractory profile records aligned to H₂ atmosphere wear pattern
-
04
EAF Transformer Bushing Failure
A single transformer failure stops the EAF for 3–8 weeks while a $5–15M replacement is sourced. Bushing hotspots are detectable by thermography 4–6 weeks before failure — but only if the scan is on the schedule. Missed thermal scans have cost plants over $200K on a single incident.
Oxmaint handles: quarterly dissolved gas analysis PMs, monthly infrared thermography scheduling, tap changer condition trending, oil-quality band alerts inside the software
The Skills Matrix
The Maintenance Skills Gap — and How the Software Bridges It
Every operations director asking whether the current crew can run a green steel plant needs this table. Some skills transfer directly. Some transfer with retraining. Some have to be hired from adjacent industries because there is nobody inside a BF-BOF plant carrying them today. Oxmaint is the maintenance management software that turns this matrix into an executable plan: every technician carries a certification record, every work order carries a required skill tag, and the CMMS enforces the match automatically inside steel operations.
| Skill Domain | BF-BOF Baseline | DRI-EAF Requirement | How Oxmaint Helps |
|---|---|---|---|
| Refractory management | Hearth carbon block, stave-lining | Shaft furnace H₂ wear + EAF zone patching | Retraining tracked in software |
| Cooling water systems | Stave circuits, hot blast stove | EAF panel cooling, transformer oil cooling | PM library transfers directly |
| Electrical high-voltage | Blower drives, auxiliary loads | 30–150 MVA EAF transformer, 50–100 kA bus | Certification records held in CMMS |
| Hydrogen safety | None | ATEX zoning, leak detection, embrittlement UT | Skill-tag routing enforced |
| Electrolyzer O&M | None | Stack replacement, catalyst, water purity | Software carries the PM playbook |
| Instrumentation | BF thermocouples, top-gas analysis | Metallization sampling, H₂ mass balance, SIL loops | Loop check history in Oxmaint |
| Rotating equipment | Blowers, pumps, cranes | Compressors, hydraulic packs, tilting drives | Direct PM library transfer |
| Electrode management | None | Column regulation, nipple joint torque, breakage | EAF module ships with playbook |
The Skills Problem, in One Sentence
Three of the Top Six Maintenance Skills for Green Steel Do Not Exist Inside Traditional Steel Plants — and Software Is How You Cover Them
Hydrogen safety, electrolyzer operations and maintenance, and electrode column management are entirely new capabilities. Building them takes 18–36 months. The plants that get there faster use Oxmaint — the maintenance management software for steel operations — as the training scaffold itself. Every PM procedure, every safety checklist, every skill tag on every work order becomes documented institutional knowledge inside the software from the first commissioning shift.
CMMS Reconfiguration
Seven Software Configuration Changes Every DRI-EAF Plant Needs
A generic CMMS that ran a BF-BOF plant for twenty years will not run a DRI-EAF plant out of the box. Asset hierarchies, PM triggers, safety-critical alerting, and spare parts logic all have to be rebuilt inside the software. These are the seven changes we ship pre-configured in Oxmaint for steel plants — the ones that separate a commissioning that hits its ramp curve from one that limps.
-
Config 01
Rebuild the Asset Hierarchy in the Software
Oxmaint models electrolyzer, H₂ system, DRI shaft, EAF, and hot transfer as top-level nodes. Every stack, cell, valve, sensor, panel, and electrode column becomes an addressable child asset with its own history inside the CMMS.
-
Config 02
Multi-Trigger PMs Running in Parallel
EAF refractory, electrodes, and hydraulic cylinders wear on heats, not days. Oxmaint runs calendar, heat-count, cycle-count, and condition-based triggers side by side, so PMs fire on whichever clock reaches its limit first.
-
Config 03
Safety-Critical Alerting Built In
Hydrogen leak detectors, SIL-rated loops, ATEX zone monitors, and CO alarms feed directly into Oxmaint. Every threshold breach generates an escalated work order with mandatory acknowledgment tracked in the software.
-
Config 04
Long-Lead Spare Parts Strategy
Electrolyzer stacks, EAF transformer components, and graphite electrodes carry 6–24 month lead times. Oxmaint re-parameterizes min-max, safety stock, and reorder points against green-era procurement realities.
-
Config 05
Three EAF Maintenance Tiers Managed by Software
EAFs run inter-heat (3–8 min), planned delay (2–8 hr), and campaign shutdown (5–14 d) maintenance tiers. Oxmaint assigns the right task to the right window automatically so nothing is missed between heats.
-
Config 06
Green Certification Tracking Inside the CMMS
CBAM reporting, embedded emissions verification, and green premium contracts require audit-grade records of what asset ran, when, on what energy source. Oxmaint is the natural home for that ledger — inside the same software the crews use daily.
-
Config 07
Skill-Tag Work Order Routing
Work orders touching hydrogen systems can only be assigned to certified technicians. Oxmaint carries every skill tag on every task, every credential on every technician, and enforces the match at assignment inside the software.
Transition Roadmap
The 24-Month Software-Led Readiness Plan
Nobody flips a switch on a green steel plant. Commissioning ramps over 18–24 months, and the maintenance organization has to ramp with it — not chase it. This is the standard phasing an Oxmaint deployment follows for steel plants making the DRI-EAF transition. Every quarter is anchored to a specific software milestone that gates the next.
-
Q1
Foundation in the Software
Build the asset hierarchy inside Oxmaint. Import equipment lists from EPC handover. Set up initial PM library for hydrogen and electrolyzer systems. Skills gap assessment logged for every named technician in the CMMS.
-
Q2
Training & Certification
Hydrogen safety training rolled out to all mechanical and electrical crews, with certifications tracked in Oxmaint. First procurement work orders fire from the software for long-lead spares — stack membranes, electrode consumables, transformer critical spares.
-
Q3
Cold Commissioning PMs
Pre-commissioning PMs run through the software against every new asset. Instrumentation loop checks, leak surveys on all hydrogen piping, transformer oil baseline dissolved gas analysis — logged in Oxmaint as the reference dataset for the life of the asset.
-
Q4
Hot Commissioning
First hydrogen through the shaft furnace. First heats through the EAF. Condition trending activates inside the software on every critical asset. Round schedules run on shift cadence through the mobile app. Findings flow into the Oxmaint deficiency register, not paper.
-
Q5
Ramp to Nameplate
Heat count triggers activate on refractory and electrode PMs. Inter-heat maintenance windows dial in. First planned outage is sequenced directly from Oxmaint findings — repair items caught during commissioning become the shutdown work package inside the software.
-
Q6+
Steady-State Optimization
MTBF and MTTR trend downward as Oxmaint's AI-assisted predictive layer builds enough asset history to flag stack degradation, transformer aging, and refractory wear months ahead. The CBAM ledger runs off the same maintenance software.
Built for Steel Plants
How the Oxmaint Maintenance Software Runs a DRI-EAF Program End to End
-
Asset Records
Every Electrolyzer Cell and Electrode Column as Its Own Asset
Individual asset records in Oxmaint for every stack, cell, panel, and column. Each carries its own install date, operating hours, and failure history inside the software — so replacements are planned against wear, not guessed.
-
Multi-Trigger PM
Calendar, Heat Count, Cycle Count and Condition Firing in Parallel
Refractory PMs on heat count. Hydraulic cylinders on cycle count. Transformer DGA on calendar. Oxmaint fires every task on the correct clock — whichever comes first — without a coordinator managing spreadsheets.
-
Safety Alerting
SIL-Rated and ATEX-Zone Alerts Escalated Automatically
Hydrogen leak detectors, CO monitors, and safety-critical loops feed directly into Oxmaint. Any breach generates an escalated work order with acknowledgment tracking and full audit trail inside the software.
-
Skill Routing
Work Orders Routed Only to Certified Technicians
Every task in Oxmaint carries a skill tag; every technician carries certifications. Hydrogen system work only routes to certified staff. The software enforces the match — protecting the plant and the audit trail.
-
Long-Lead Procurement
Reorders Fired 6–24 Months Ahead of Need
Condition trending inside Oxmaint on stacks, electrodes, and transformer components projects replacement dates. The software fires procurement work orders inside the correct lead window at standard pricing.
-
CBAM Ledger
Green Certification and Embedded Emissions Records
Every heat, every energy source, every asset — captured inside the maintenance software. The audit trail CBAM and green premium contracts require lives inside the same Oxmaint CMMS your crews use every day.
Measured Outcomes
What Steel Plants Gain When Oxmaint Software Runs the Transition

Day One
Audit-Ready CBAM Records
From the first commissioning shift, embedded emissions and green certification records live inside Oxmaint — no last-minute reconstruction before a compliance audit or premium contract review.
Frequently Asked
DRI-EAF Maintenance Software Questions
Can our current maintenance team run a hydrogen DRI plant on Oxmaint?
About 60% of the skill base transfers — refractory, cooling, rotating equipment, general instrumentation. The remaining 40% has to be built or hired: hydrogen safety, electrolyzer O&M, high-voltage transformer work, electrode column management. Oxmaint holds every certification, PM procedure, and safety checklist in the software so the capability build compresses from 36 months to closer to 18. Sign up for Oxmaint to use the maintenance software as your skills-matrix and training scaffold from day one.
What is the highest-consequence failure mode Oxmaint should be configured against first?
EAF transformer failure. Replacement lead times run 12–24 months, replacement cost is $5–15M, and a single failure stops production for weeks. Monthly infrared thermography and quarterly dissolved gas analysis catch degradation 30–60 days ahead — Oxmaint enforces the schedule inside the software so it never gets missed.
How does the software handle CBAM and green premium record-keeping?
Oxmaint records every heat against the assets and energy sources it consumed. Embedded emissions calculations, green certification status, and audit trails all live inside the same maintenance management software your crews use daily — so records are contemporaneous, not reconstructed. Book a demo to see how Oxmaint runs the CBAM ledger alongside your PM program in the software.
When should we start configuring Oxmaint — before or after EPC handover?
Before. Asset hierarchy, PM library, and safety alerting all have to be live inside the software for cold commissioning. Waiting until hot commissioning means your first hydrogen leak survey, transformer baseline DGA, and instrumentation loop checks are not captured against the asset record they belong to — losing months of baseline data. Sign up for Oxmaint to configure the maintenance software in parallel with EPC construction.
