Practice

Reliability Engineering

Reliability engineering is the analytical core of asset management: understanding how equipment fails, what the failure costs, and which intervention actually changes the outcome.

The challenge

Repeat failures are a design and analysis problem, not a maintenance effort problem.

When the same pump fails four times a year, the issue is rarely that the artisans are not working hard enough. It is that the failure mechanism has never been properly identified, so every intervention treats a symptom. The plant becomes very good at fast repairs and never gets better at not failing.

Our reliability engineers apply structured analysis — RCM, FMECA, root cause analysis, Weibull and RAM modelling — to find the actual mechanism, quantify its consequence, and specify the change that eliminates it. Sometimes that is a tactic. Often it is a design, operating or materials decision.

Capabilities

What this practice covers

Reliability-Centred Maintenance (RCM)

Full or streamlined RCM studies on critical systems, producing defensible tactics traced to specific failure modes and consequences.

FMEA / FMECA

Structured failure mode, effects and criticality analysis for equipment classes and new designs, including detectability assessment.

Root Cause Analysis

Facilitated RCA on significant and repeat failures, driving to physical, human and latent causes with tracked corrective actions.

Defect elimination programmes

A standing process — not a one-off study — for identifying, prioritising and permanently removing recurring defects.

RAM & availability modelling

Reliability, availability and maintainability modelling to test configurations, redundancy and sparing before capital is committed.

Life cycle costing

Whole-of-life cost comparison across options, so replace-versus-refurbish decisions are made on evidence.

How we work

Our approach

Scope & data

Select systems by consequence, assemble failure history, drawings, process conditions and operating context.

Analyse

Run the appropriate study — RCM, FMECA, RCA or modelling — with the operating and maintenance teams in the room.

Decide

Convert findings into tactic changes, design changes, operating limits or spares decisions, each with a business case.

Verify

Track the failure mode after implementation to confirm the mechanism is genuinely eliminated, not displaced.

Deliverables

What you receive

Tangible, usable outputs — structured for the systems and people who have to live with them after we leave.

FAQ

Common questions

On genuinely critical systems, yes — it is the most rigorous method available and the logic trail survives scrutiny. On the wider asset base, streamlined RCM or template-based analysis reaches most of the benefit at a fraction of the cost. We deliberately choose the depth per system.

The analysis is only as good as the operating knowledge in the room. We typically need a maintenance technician, an operator, a planner and a process engineer for each system, in facilitated sessions.

Then a maintenance tactic can only manage it, never fix it. We say so plainly, quantify the ongoing cost of managing versus resolving, and support the modification case.

Yes. Capability transfer is part of most engagements — we would rather leave behind a functioning reliability process than a dependency.
