Compressor Performance, Reliability, Integrity & Life Extension

Understand why your compressor is underperforming before deciding what to repair, modify or replace.

ETA combines compressor design knowledge, performance analysis, process-system understanding and operating data to determine the root causes of poor performance and reliability—and

Four Columns
What decision are you facing?
Performance data is only the beginning.
Why?
What is causing deterioration or recurring failure?
What next?
Optimise, repair, rewheel, rehabilitate or replace?
How long?
How much useful economic life can be recovered?
The Challenge
The Challenge

Condition monitoring tells you something changed. It does not always tell you why.

Reliability problems can originate in compressor aerodynamics, process conditions, seals, controls, auxiliaries, maintenance practices or interaction with the wider system.

ETA assesses the complete operating context rather than treating each symptom independently.

Typical client questions

  • How efficiently is the compressor operating?
  • How far has performance moved from design?
  • Why do reliability problems keep recurring?
  • Is the machine still fit for continued service?
  • Can it safely operate at changed duty?
  • Would a rewheel solve the problem?
  • Is rehabilitation more economic than replacement?
  • How can maintenance cost and OPEX be reduced?
Specialist Engineering

From performance benchmark to
life-extension decision

Performance Benchmarking

Compare actual operating performance against design, predicted and historical behaviour.

Root-Cause Analysis

Investigate recurring trips, low capacity, high temperature, efficiency loss and chronic issues.

Integrity & Fitness for Service

Assess whether ageing equipment can continue operating safely and reliably.

Residual-Life Assessment

Support continued operation, rehabilitation and replacement planning.

Rewheel & Revamp Studies

Determine whether aerodynamic redesign or package modification can restore useful operating range.

Maintenance & OPEX Optimisation

Identify interventions that reduce maintenance, energy use and production loss.

Typical Deliverables

Move from "something is wrong"
to a prioritised plan

Performance Benchmark

Current versus expected compressor behaviour.

Root-Cause Findings

Evidence-based explanation of recurring problems.

Fitness-for-Service Assessment

Continued-operation assessment under relevant duty.

Modification Options

Repair, operational change, rewheel, revamp or replacement.

Life-Extension Roadmap

Prioritised interventions and recommended timing.

Business Case Inputs

Performance, OPEX, maintenance and production benefits.

Keep ageing assets
productive for as long
as it makes technical
and economic sense.

The decision is rarely simply “repair or
replace.” It is how to recover the required
reliability and production at acceptable risk
and cost.
