Oil & Gas Equipment
Repair & Modernization

In Oil and Gas, the Equipment That Can't Fail Is Usually the One That Does.

A pump train that's been flagged on vibration for three months. A compressor gearbox that's been trending hot. A critical driver that goes down the week before a turnaround window opens. Every reliability engineer and maintenance manager in oil and gas knows what it feels like when the equipment that the whole operation depends on becomes the thing you're managing around.

Enprotech repairs, rebuilds, and modernizes critical rotating and mechanical equipment in upstream, midstream, and downstream operations. We bring 85+ years of heavy industrial engineering and field service capability to equipment that has to perform under process conditions that don't leave room for a second chance.

Tell us what equipment you're running and what's giving you trouble. We'll help you figure out what needs to happen.

What Puts Rotating Equipment
at Risk in Oil & Gas

The failure modes in oil and gas rotating equipment are well understood by anyone who's spent
time in a reliability role. They're not unpredictable — they're the result of operating conditions
that accumulate over time and show up when the margin runs out.

Cyclic Loading & Fatigue

Cyclic Loading & Fatigue

Start-stop cycles, surge events, torque spikes, and process upsets create fatigue loading that accumulates in shafts, couplings, and bearing housings over time. The damage is rarely visible until a crack propagates or a shaft deflects enough to affect seal performance. By then, what was a condition monitoring flag has become a teardown event.

Flask

Process Fluid & Chemical Exposure

Hydrocarbons, produced water, H2S, and process chemicals attack pump internals, seal faces, gland packing, and baseplate coatings in ways that are specific to the fluid handled and the operating temperature. A rebuild that doesn't account for the actual process conditions will follow the same degradation curve as the original.

Thermometer

Thermal Growth & Misalignment

Thermal expansion during operation changes shaft centerline relationships between driver and driven equipment. Coupled with baseplate settling, pipe strain, and inadequate soft-foot correction, misalignment develops under operating conditions even when cold alignment looks acceptable. Elevated vibration, accelerated bearing wear, and shortened seal life follow.

Pump & Compressor Train Rebuilds

We rebuild centrifugal and positive displacement pumps, compressor gearboxes, and driver assemblies to restore mechanical integrity and performance. Impeller hydraulics, shaft straightness, bearing fits, seal chamber geometry, and coupling balance are all verified not assumed. A rebuilt pump that returns to service trending the wrong way on vibration isn't a rebuild. We don't hand those back.

Screwdriver

Precision Machining & Shaft Work

Shaft journals, sleeve fits, keyways, and coupling hubs that have worn or been damaged in service need precision machining to restore dimensional integrity. We machine shafts, restore bearing fits, and correct coupling hub geometry to tolerances appropriate for the service not to a generic standard that happens to be within print tolerance.

HardHat

Skid Frame & Structural Repair

Baseplate cracks, grout deterioration, anchor bolt failures, and structural corrosion affect alignment stability under operating conditions. We repair and restore skid frames and baseplates with the operating thermal and dynamic loads in mind not just what looks acceptable in a static inspection.

24/7 Emergency Field Response

When a pump train trips, a compressor gearbox fails, or a critical driver goes down, we mobilize fast. Our field teams arrive with the machining, mechanical, and diagnostic capability to assess the failure and start repairs. In oil and gas, equipment failure has consequences that compound quickly we know that, and we move accordingly.

When Equipment Goes Down, the Clock Starts Immediately

A failed pump in a refinery or a tripped compressor at a midstream station doesn't sit idle while the repair gets organized. We deploy field teams quickly with the tooling and expertise to assess the failure on-site and determine what needs to come out for a controlled rebuild versus what can be stabilized in place.

The goal is a fast, documented return to service with a clear understanding of what failed and why, so the next planned outage can address what's actually driving the condition.

Dealing with an equipment failure right now? Call us. We're available 24/7.

What Reliability and Maintenance Teams Focus On

These are the priorities we see consistently in oil and gas reliability programs:

  • Vibration trending that's moving the wrong direction and needs a root cause, not another data point.
  • A pump or compressor rebuild that needs to come back to performing to its original curve.
  • Rotating assembly components that are worn, damaged, or no longer available through the OEM.
  • Skid or baseplate issues that are affecting alignment stability under operating conditions.
  • A turnaround window that needs repair work scoped, executed, and documented within the available time.
  • Legacy equipment where tribal knowledge is the only documentation — and it's walking out the door.

How Enprotech Approaches Rotating
Equipment Reliability

Root Cause Before Return to Service

A pump that failed at its mechanical seal failed for a reason shaft deflection, misalignment, cavitation, improper seal flush, or seal selection. Replacing the seal and putting the pump back on line rebuilds the part, not the system. We identify the mechanical sequence that drove the failure and address it in the rebuild scope so the MTBF improves, not just resets.

Rebuilt to the Demands of the Service Not the Nameplate

Process conditions in oil and gas are specific: the fluid, the temperature, the pressure, the duty cycle, the start-stop frequency. A rebuild that accounts for those conditions in material selection, clearance specification, and assembly practice will outlast one that doesn't. We build to the service, not to a generic standard.

Work Scoped and Executed Within Your Turnaround Window

Turnaround windows in oil and gas are planned, protected, and expensive. We scope rebuild work to fit within the window available, stage work that can't be completed in a single outage, and document everything so the next turnaround starts from a known baseline rather than a question mark.

Work Scoped and Executed Within Your Turnaround Window

Documentation That Supports Your Reliability Program

Every rebuild produces documentation of the as-found condition, measurements, what was corrected, and what the assembly was returned to. That feeds your reliability program, your CMMS records, and your condition monitoring baseline for the next service interval. We deliver it because a rebuild without records is just a black box.

Assessment with Transparency

What to Expect From Enprotech

Turnaround and Outage Support

Turnaround and Outage Support

We plan and execute pump, gearbox, and rotating assembly rebuild work within your turnaround schedule. Scope is confirmed before the work starts, milestones are tracked, and documentation is complete before startup. Your turnaround doesn't extend because a rebuild ran long or a part wasn't ready.

Work Executed to a Consistent Standard

Work Executed to a Consistent Standard

Five facilities. One standard. Whether work is performed at our shop or in the field, the inspection criteria, assembly practices, and documentation requirements are the same. You get consistent output regardless of which crew does the work or where it happens.

Package-1

Parts for Equipment the OEM No Longer Supports

Older pump casings, impellers, gearbox internals, and shaft components that are no longer available through the OEM can be reverse-engineered and manufactured to original specification. Legacy equipment stays in service without being held hostage to parts availability or OEM lead times.

ShieldCheck-1

Fewer Unplanned Events Over Time

Reliability programs that include planned rebuilds, condition-based inspection, and parts availability planning see fewer unplanned equipment failures. We support that shift — from reactive repair to a maintenance posture where the next failure is anticipated and managed before it interrupts operations.

Frequently asked questions

Do you support refinery, midstream, and upstream equipment?

Yes. We work across upstream production, midstream compression and pipeline, and downstream refinery and petrochemical operations — covering centrifugal and positive displacement pumps, compressor gearboxes, driver assemblies, rotating equipment structural systems, and associated controls and drive components.

Can you work in classified or permitted facilities?

Yes. Our field crews are experienced working in controlled industrial environments and follow site-specific safety protocols and access requirements. We work within the safety management systems your facility has in place.

Do you rebuild on-site or at your facilities?

Both. Field teams perform emergency assessment, stabilization, and smaller-scope repairs on-site. Larger rotating assemblies — pumps, gearboxes, compressor components — come to our North American facilities for precision machining, controlled assembly, and inspection. The scope determines where the work happens.

Can you help integrate condition monitoring or controls into older equipment?

Yes. We coordinate controls and sensor modernization alongside mechanical rebuild work. Updated drives, vibration monitoring, and control logic can be integrated into existing equipment without full replacement — extending useful life and improving visibility into asset condition.

Can you support equipment the OEM no longer covers?

Yes. Reverse engineering legacy rotating equipment components is a core capability. We can manufacture impellers, shaft assemblies, gearbox internals, and coupling components to original specification when OEM sourcing isn't available or practical.

What documentation comes with a rebuild?

Full as-found and as-built documentation — dimensional records, inspection findings, what was corrected, and what the assembly was returned to. That supports your reliability program, your CMMS entries, and your condition monitoring baseline going forward.

The Equipment You're Managing Around Needs More Than Another Workaround.

A pump with rising vibration, a gearbox with a temperature trend, a compressor that's been performing below curve — these conditions don't resolve themselves. The question is whether they get addressed during a planned window or after they make that decision for you.

Tell us what equipment you're running and where it's giving you trouble. We'll help you figure out what needs to happen and when — before the condition becomes the schedule.
