E.S.M. provides Reliability Engineering services to support the design and operation of complex systems, with a focus on improving availability, performance and lifecycle outcomes.

We provide practical Reliability Engineering services that:

  • Identify and prioritise failure risks
  • Quantify system performance (availability, uptime, risk)
  • Support design, maintenance and operational decisions
  • Improve safety, reliability and lifecycle outcomes

Our Services

Failure Modes & Effects Analysis (FMEA / FMECA)

FMEA / FMECA is a structured approach of evaluating an item to identify potential failure modes and assess their effects on the performance of the item and wider systems and environment.  The analysis identifies how failures are detected and whether controls are necessary to prevent or mitigate the failure.

Typical FMEA services include:

  • Definition of scope, system boundaries and functions
  • Identification of failure modes (system and equipment level)
  • Assessment of impacts on safety, operations and availability
  • Criticality ranking (FMECA using RPN or similar methods)
  • Review of existing controls and detection methods
  • Targeted risk reduction and reliability improvements
  • Facilitated multidisciplinary workshops

FMEA can be a valuable tool at any stage in a project or asset lifecycle:

  • Design: Improve component selection, redundancy and detection strategies
  • Operations: Inform maintenance, inspections and spares strategies
  • Processes: Reduce errors and improve workflow reliability

Applicable standards: AS/NZS IEC 60812 and SAE J1739

Quantitative Reliability & Availability Analysis

Quantitative Reliability & Availability Analysis involves the evaluation of system models using real or theoretical reliability data to demonstrate that systems meet required targets.

Typical outputs:

  • Mean Time Between Failure (MTBF)
  • Mean Time to Repair (MTTR)
  • Probability of Failure on Demand (PFD)
  • System availability and uptime

Applications:

  • Demonstrating compliance with safety and performance requirements
  • Supporting functional and machine safety lifecycle
  • Verifying design performance before implementation
  • Monitoring and validating operational performance

Techniques:

  • Reliability Block Diagrams
  • Fault Tree Analysis
  • Event Tree Analysis
  • Markov Chains

Applicable standards: AS IEC 61078, AS IEC 61508, AS IEC 61511

Reliability, Availability & Maintainability (RAM) Studies

Our RAM studies combine the qualitative aspects of FMEA with quantitative analysis to develop a comprehensive understanding of an asset’s availability and reliability in performing its intended function.

Our integrated approach ensures that failure risks are:

  • Identified early – before they become costly issues
  • Quantified using proven methods
  • Managed through practical, implementable control measures

The result is improved reliability, reduced downtime and better lifecycle performance.

Industries & Applications

We work across a range of industries to support safe, reliable and efficient operations –from concept design through to ongoing asset management.

  • Operational technology
  • Standby generator systems
  • Transmission protection schemes
  • Power generation and battery energy storage
  • Machine interlock functions and emergency stop
  • Process safety

Tools and Templates

E.S.M. has developed a suite of tools and templates that client organisations can use to support the delivery of successful engineering projects.
