Oil & Gas maintenance: availability and safety are decided on the maintenance floor

In oil and gas, an offshore platform loses about 27 days of production a year and close to $38 million, because equipment still runs mostly on reactive maintenance. Mimorian gives your maintenance technicians reliable, explainable diagnostics across the equipment fleet, so you hold availability and cut human risk, with humans in control.

An aging fleet, maintenance still reactive

Over five years, the sector has tightened its capital discipline while the cost of unplanned downtime passed $500,000 per hour in refining and Oil & Gas, more than double the 2019 level. Production stays constrained by equipment availability: assets run at only 77% of their capacity, close to $200 billion in missed revenue per year worldwide.

At the same time, three organizations out of four remain on reactive or calendar-based maintenance, and more than half of UK North Sea installations run beyond their design life, which strains maintenance and inspection. On safety, the HSE estimates that 50 to 70% of offshore hydrocarbon releases have causes linked to human factors, including during equipment maintenance. The workforce is also shrinking and aging: 48% of the energy workforce is 45 or older, and the know-how of senior staff leaves with them.

The equipment fleet to maintain in Oil & Gas

Mimorian addresses the equipment on the site and the platform, in an environment where maintenance is a safety concern as much as an availability one.

Rotating and pressurized machinery

Pumps, compressors, turbines, separators, heat exchangers. Work on this equipment puts the safety of the installation at stake and calls for a high level of decision rigor.

Valves, lines and instrumented safety

Valves, process lines, emergency shutdown and safety-instrumented systems. Knowing the exact condition of every component is decisive before any return to service.

Equipment in hazardous zones

Assets installed in explosive atmospheres, bound by safety rules. The technician needs the right information at the right moment, without leaving the zone to look for a document.

Your pain points, what maintenance changes

Five concrete situations from the Oil & Gas floor, and the lever Mimorian pulls each time, always through maintenance and under human supervision.

The pain

One hour of unplanned downtime tops $500,000 and a platform loses about 27 days a year, because maintenance stays largely reactive.

What Mimorian changes

Mimorian helps the technician diagnose fleet failures faster and more accurately, so they can act before the breakdown hits and return equipment to service without error. Fewer unplanned stops translate directly into production days held.

The pain

The maintenance workforce is shrinking and aging (48% over 45), technical roles are the hardest to fill, and contractors are sometimes less experienced.

What Mimorian changes

Mimorian puts the right diagnosis and the right maintenance action within reach of the new technician, with an explainable decision they can grow into. A technician who becomes autonomous faster limits the impact of turnover on fleet availability.

The pain

The HSE estimates that 50 to 70% of offshore hydrocarbon releases have causes linked to human factors, including during equipment maintenance.

What Mimorian changes

Mimorian makes lockout, return to service and intervention more reliable by giving the technician a verified diagnosis and an explainable procedure, humans in control. Fewer errors during maintenance and more reliable equipment reduce accident risk, without ever claiming to remove it.

The pain

Senior departures take maintenance know-how with them at a time when more than half of the North Sea fleet runs beyond its design life.

What Mimorian changes

Mimorian captures and makes maintenance know-how available on aging equipment. A proven diagnosis stays available even after the person who held it leaves, which protects the availability and safety of the installations.

The pain

Cost discipline is intensifying and squeezing margins, while 75% of organizations remain on reactive or calendar-based maintenance.

What Mimorian changes

Mimorian helps move from reactive maintenance to maintenance better targeted by diagnosis, cutting unnecessary work and costly breakdowns. A lower cost of ownership across the fleet protects the margin under pressure.

These levers build on our AI-guided diagnostics and maintenance know-how capture capabilities, detailed in our reference guides.

Typical rollout: alongside your maintenance, no IT big bang

The first question a plant director asks about a maintenance AI is the integration risk. Mimorian answers with a light rollout, measurable fast, driven by the field.

A ready-to-use SaaS workstation for the technician

Mimorian runs on the technician's device (tablet, smartphone, browser), alongside your current tools. The technician opens it in front of a complex breakdown, talks through it by voice, gets targeted hypotheses and runs the diagnosis. The structured report then flows back into your CMMS by export or API.

First value in two weeks, in a closed loop

The pilot starts on a limited scope: a few sensitive machines, one critical line. An export is enough to start, the connection to your information system comes later, at your pace. The first measurable value lands in two weeks on a real breakdown.

Adoption driven by the field

The technician adopts it because it saves 30 to 45 minutes a day on admin work and makes the job more interesting. Once value is proven on the pilot, the rollout to other lines and sites happens step by step.

3 questions to ask yourself

How do you reduce the risk tied to a maintenance error?

By making the decision more reliable and the transfer safer. Mimorian offers traced hypotheses and tests to settle them, and captures the exact condition of the machine at each intervention. The human validates, the AI structures and documents.

Does the AI replace the technician's judgment on a sensitive site?

No. Mimorian works under human supervision: it proposes, the technician decides. Every recommendation is explainable and traceable back to its source.

How do you hold availability on a fleet running beyond its design life?

By capturing the maintenance know-how of senior staff and speeding up diagnostics on older equipment. Proven know-how stays in the plant and serves the whole team, even after a departure.
