Risk & Reliability Analysis

We strongly believe that risk and reliability analysis should be used as an integral part of the design process or asset management to support the development of solutions to improve reliability and functionality.

There is a vast range of risk and reliability tools and techniques that can be applied to support the engineering design process and operations decision making.  However each of the tools has strengths and weaknesses in different engineering scenarios. We use our experience and expert knowledge of the tools and techniques to identify which tool is best for each individual problem.

Types of analysis that we can provide include:

  • Common Cause Failure Analysis (CCFA) - to identify and assess components at risk of (near) simultaneous failure from a common event
  • Reliability Value Analysis (RVA) - to understand cost and consequences of failure and identify the value of improvement opportunities.
  • Event Tree Analysis (ETA) - to describe how failure events propagate through a system and determine likely consequences
  • Risk Based Decision Making (RBDM) - to support complex project and engineering decisions at each stage, accounting for uncertainty
  • Failure Modes, Effects (and Criticality) Analysis (FMEA/FMECA) - to identify system, design or process failure modes for assessing and managing the risk.
  • Root Cause Failure Analysis (RCFA) - to resolve problems affecting reliability by assessing facts relating to a failure or event at root cause.
  • Fault Tree Analysis (FTA) - to identify the technical cause of specific unwanted events and predict reliability performance.
  • Structural Reliability Analysis (SRA) - to predict design reliability when physical prototypes and qualification tests are impossible.
  • Technology Readiness Assessment (TRL) - to assess current level of readiness of technology for project use, based on qualification maturity
  • Reliability, Availability and Maintainability Analysis (RAM) - to quantify a system’s ability to remain in an operational state.
  • Technical Risk Assessment and Categorisation (TRC) - to assess what is new or changed from previous projects, that introduces uncertainty or risk to reliability.
  • Reliability Centred Maintenance (RCM) - to optimise maintenance based on potential failure mode criticality, supported by data to mitigate risk.

As an example of our offering, Astrimar provide a service through the Industrial Appstore to tailor a FMEA / FMECA to meet your requirements, so that the FMEA / FMECA process can help you to understand your current risks and to plan value enhancing actions to mitigate or manage those risks.  Astrimar will provide an application specific template including an example set of prepopulated rows. We can also provide some initial coaching to help get started.  Additional FMECA support services, include:   Facilitating FMEA / FMECA workshops for any of the applications listed above, identifying appropriate failure rate data and post-processing the FMEA / FMECA data to provide recommendations and actions for reliability improvements, qualification testing and analysis, integrity management, preparedness response and spares holding.   Our services align to the best practices defined in API RP 17N, ISO 20815, DNV RP A203 and the new API RP 17Q (2018).
