Building Reliability Through Structured Risk Evaluation
Introduction
Every system is only as strong as its weakest link and identifying that weakness early can save time, cost, and reputation. At iFluids Engineering, we use a Tool known as “Failure Mode and Effects Analysis (FMEA)” to ensure that your system is designed and operated with safety in-mind; making sure of its robustness to failures.
Our FMEA methodology is a known reliability and risk centric tool which determine how and where a system may fail, analyze potential impact of failure, & identify where action needs to be taken to prevent failure from occurring. Whether it’s a refinery, compressor station or control system, our discrete design methodology is able to incorporate process and human reliability into one structured approach.
What Is Failure Mode and Effects Analysis (FMEA)?
Failure Mode and Effects Analysis (FMEA) is a structured, evidence-based method used to identify potential failure modes within a system, analyze the effects of those failures, and prioritize risk reduction measures.
It provides an early warning mechanism, allowing teams to anticipate and prevent problems before they impact operations.
Originally developed for aerospace reliability, FMEA analysis is now standard across industries including oil & gas, chemical, and utilities helping organizations enhance design integrity, maintenance planning, and overall operational safety.
FMEA Process
The FMEA process followed by iFluids Engineering is systematic, collaborative, and data-driven. It enables cross-functional teams to assess risks objectively and implement effective controls before costly failures occur.
Below are the typical stages we follow:
- System Definition
Clearly outline the system or process under review defining functional boundaries, operating conditions, and performance expectations. - Identify Potential Failure Modes
Determine how each component, subsystem, or process could fail including design errors, material degradation, or operational deviations. - Analyze Effects and Causes
Assess the potential impact of each failure mode on safety, reliability, environment, and quality. Identify credible root causes using design data, inspection history, and expert judgment. - Evaluate Severity, Occurrence, and Detection
Assign numerical or qualitative ratings to evaluate how severe the effect is, how often it might occur, and how likely it is to be detected before causing impact. - Calculate Risk Priority Number (RPN)
Multiply the three ratings (S × O × D) to prioritize the most critical failure modes for corrective action. - Recommend Corrective Actions
Propose engineering or procedural changes that reduce occurrence or improve detection such as redesign, redundancy, monitoring, or training. - Review and Control
Document, review, and update the analysis periodically or after process changes to ensure the FMEA remains current and effective.
This FMEA process not only improves reliability but also enhances communication between design, maintenance, and safety teams by creating a common language of risk.
FMEA Analysis
At iFluids Engineering, we perform FMEA analysis as both a design and operational reliability study. It goes beyond simply listing failure modes; it delivers insight into how those failures interact with real operating conditions.
Our FMEA analysis approach combines field data, engineering simulation, and practical experience:
- Design FMEA (DFMEA): Applied during concept or FEED stages to identify design-related vulnerabilities before manufacturing or installation.
- Process FMEA (PFMEA): Evaluates process-level failures, deviations, and operator interactions during operations or maintenance.
- Maintenance FMEA (MFMEA): Focuses on reliability-centered maintenance, identifying components with high failure probability or maintenance cost impact.
Each analysis is supported by detailed documentation, risk matrices, and recommended mitigation strategies enabling your team to make informed design, operation, and inspection decisions.
Our FMEA Methodology
At iFluids Engineering, our FMEA methodology adapts to the complexity of each project. Whether it’s a refinery subsystem or an offshore process skid, we ensure every step follows international standards such as ISO 9001, API 580, and IEC 60812.
Step 1: Define the Scope
We establish boundaries and system hierarchy to ensure consistency across design and operation.
Step 2: Identify Failure Modes
We identify component-level and process-related failure scenarios using historical data, manufacturer input, and engineering experience.
Step 3: Determine Effects and Causes
Each failure mode is linked to specific effects (production loss, safety hazard, environmental release) and underlying causes (corrosion, fatigue, human error).
Step 4: Assign Ratings and Calculate RPN
Severity, Occurrence, and Detection are rated and multiplied to derive the Risk Priority Number guiding focus toward high-impact issues.
Step 5: Recommend Mitigation Measures
We propose actionable design or procedural controls such as alarms, interlocks, redundancy, and inspection strategies.
Step 6: Review, Approve, and Update
We conduct peer reviews and management validation to finalize the report, ensuring traceability and alignment with future design changes.
Benefits of Performing FMEA
- Identifies weak links before system failure
- Reduces unplanned downtime and maintenance cost
- Improves compliance with ISO, API, and CCPS standards
- Enhances communication across technical teams
- Establishes a continuous improvement framework
By implementing the FMEA process early, clients gain control over risk rather than reacting to it after failure occurs.

Frequently Asked Questions
FMEA enables a structured approach to systematically attempting to identify failure modes, their effects and causes of failure and how they might be prevented through risk reduction ensuring the reliability of the final product/ process.
The FMEA method identifies error patterns at early development or operation phases. This gives design and sustainment teams the ability to institute proactive measures that will prevent failures, resulting in enhanced system reliability and reduced downtime.
FMEA study is heavily used in oil & gas, chemical processes, power generation and manufacturing – we are talking about industries where equipment reliability and operational safety are paramount as well as being required to assure compliance to regulation.
An FMEA consultant helps companies take their formal, effective FMEA culture to the next level. They verify that the method is consistent with international reliability standards and can lead to measurable performance improvements.
Yes. FMEA is also tools-and-methods set that supplements and builds on other reliability work (such as Risk-Based Inspection [RBI], Safety Integrity Level [SIL] and Root Cause Analysis [RCA]) – together constituting a complete framework to improve reliability.
