A steel plant running three shifts generates two handovers per day, 730 handovers per year, and at least two moments every 24 hours where critical maintenance information either transfers cleanly or disappears. A paper-based system in that environment is not a documentation system — it is a lottery. The $90 pressure sensor "acting funny" that the outgoing shift mentioned but never logged becomes the $127,000 production loss the incoming shift inherits without context. At $50,000–$200,000 per hour of unplanned downtime, the cost of a failed shift handover is not administrative — it is operational. OxMaint's shift-based work order management system ensures every open work order, every safety lockout, every in-progress PM, and every deferred corrective action transfers automatically at shift change — without the outgoing supervisor writing a word.

OxMaint Work Order Prioritisation Engine — How Steel Plant WOs Get Scored
Not all work orders are equal in a steel plant. A failing water-cooled panel on the EAF roof is not the same priority as a lobby lighting replacement. OxMaint's prioritisation engine scores every work order at creation using four weighted factors — and re-scores it automatically if conditions change.
Asset Criticality
Weight: 35%
Based on the asset's criticality classification — A (production-critical), B (important), or C (non-critical) — set in the asset hierarchy. A-class assets carrying liquid metal are scored maximum. C-class admin assets score minimum regardless of fault severity.
Safety Risk
Weight: 30%
Any WO tagged with a safety code — electrical exposed, steam release, structural damage, lifting equipment defect — receives a safety multiplier that overrides production priority. A non-critical asset with a safety code ranks higher than a critical asset with a functional fault.
Production Impact
Weight: 25%
WOs linked to assets on the active production schedule — the current heat's ladle crane, the running caster, the active reheat furnace bay — receive elevated scoring. An identical fault on an idle asset scores lower. Scoring adjusts in real time as the production schedule shifts.
Age & Deferral Count
Weight: 10%
WOs older than 48 hours gain an age multiplier that increases by 5% per shift. WOs deferred more than twice receive an automatic escalation flag to the area maintenance manager. This prevents low-priority WOs from ageing indefinitely in the backlog while seeming safe to defer.
Priority Output — 4 Levels
P1 EmergencySafety risk OR production-critical asset failure — assign within 30 minutes, notify supervisor immediately
P2 UrgentProduction impact, no immediate safety risk — assign within current shift, parts staged same shift
P3 PlannedCorrective or PM work — schedule within 7 days, include in next weekly maintenance window
P4 DeferredNon-critical, no production or safety impact — schedule within 30 days, auto-escalates if not actioned
Every Open Work Order. Every Shift. Every Technician. One Dashboard.
OxMaint gives incoming shift supervisors a live view of every open WO, active lockout, in-progress repair, and overdue PM — without the outgoing shift writing a single line of handover notes.
Shift Handover Dashboard — What the Incoming Supervisor Sees
At 06:00 handover, the incoming shift supervisor opens OxMaint on a tablet. No verbal briefing has happened yet. This is what the system shows — automatically, for the Bay 4 area in a 2,500-tonne/day integrated plant:

"
In a 24/7 steel plant, the maintenance system is only as good as its worst handover. I have seen plants with world-class technicians and correctly sized spare parts inventories still running at 50% schedule compliance — not because of skill or stock, but because the incoming shift could not see what the outgoing shift left unfinished. The work order for the partially repaired pump was in the outgoing supervisor's head, not in the system. The technician who started the job was not there when the replacement arrived. The part was in the storeroom waiting, the equipment was available, the technician had the skill — but nobody connected those three things because the handover was verbal. The moment you put a digital work order between a fault and a fix, everything that was invisible becomes visible: what is open, what is in progress, what is waiting for a part, and what the last person who touched the asset found. That visibility is where the 40% MTTR improvement comes from. Not from faster repairs — from faster starts.

Frequently Asked Questions
How does OxMaint eliminate duplicate work orders across shifts in a large steel plant?
OxMaint's duplicate detection checks every new work order request against all open WOs for the same asset with the same failure code within a 4-hour window. If a match is found, the incoming shift technician sees the existing WO with its current status, assigned technician, parts staged, and work completed — rather than raising a new order for the same fault. This also prevents the common scenario where an incoming shift supervisor raises a P1 emergency on an asset that night shift already has under repair, resulting in two crews and no coordination. For critical assets like ladle cranes and casters, the
AI predictive maintenance layer adds sensor-state context to every open WO — so the incoming supervisor knows not just that the WO is open, but whether the asset condition has changed since the WO was created.

How does the shift handover log connect to OxMaint's permit-to-work system?
Every active isolation and safety lockout in OxMaint is automatically listed in the shift handover dashboard under "Active Lockouts" — showing asset, lock owner, timestamp, and the work order the lockout is serving. The
permit-to-work system prevents any new work on a locked-out asset from proceeding without confirming the lockout status — which the incoming shift sees on handover. When a PTW is pending and a work order is on Hold, both statuses are visible simultaneously on the incoming supervisor's dashboard so they can action the PTW approval immediately at shift start rather than discovering the hold at 09:00.

Can maintenance technicians use OxMaint's work order system on the plant floor without connectivity?
Yes — OxMaint's mobile work order execution works fully offline, as described in detail in the
mobile inspection app guide. Technicians receive their shift work order queue pre-cached to their device. They can start, update, add photos, log parts used, and complete work orders without network connection. All updates sync automatically when the device reconnects. The supervisor's handover dashboard updates in real time once the sync occurs — so a repair completed in the casting bay at 05:30 appears as Closed on the handover board by the time the 06:00 supervisor review begins.

How does shift-based work order data feed into OEE and reliability benchmarking?
Every work order in OxMaint carries a fault code, an asset link, a start timestamp, and a close timestamp — which are the raw inputs for MTTR calculation. Work order age at close gives backlog time. Recurrence of the same fault code on the same asset within 30 days flags a repeat failure for root cause review. These metrics feed directly into the
OEE and MTBF benchmarking dashboard — so the shift-by-shift work order record becomes the data source for plant reliability improvement, not just the operational tool for today's repairs. And when
SCADA alarms are integrated, fault-to-WO-creation time is also measured — the gap between process anomaly and maintenance action, which is where most MTTR opportunity lives.
