Reliability Analysis

H-ON Consulting: Safety Engineering - Certificazione SIL e Safety Life Cycle

Are you a manufacturer who needs to identify the hazardous failure modes and rates of a specific equipment or industrial component?

Our specialists carry out the reliability analysis of industrial devices and self-built components in order to determine the main failure factors, the specific failure rate and its relevance within the industrial process. This type of assessment is useful to understand how the failure of a single device can affect the entire system, and what are the consequences. The reliability assessment is recommended for key devices whose correct operation is crucial for the availability of the entire system or industrial process. We specialize in carrying out all main availability assessments for single self-built components, including FMEDA, FMECA, Event Tree, Fault Tree, and FMD Study.

targeted solutions to validate the conformity of a sis according to the iec 61511 standard for end users

SIL (Safety Integrity Level) Verification & Validation

Are you a system integrator or an end-user of systems intended to perform one or more safety functions?

The development and commissioning of a Safety Instrumented System (SIS) is certainly connected to the use of single suitable components which are implemented into safety-related control functions. However, the selection and combination of components which are individually able to achieve the agreed SIL (Safety Integrity Level) does not automatically imply that the entire SIS can be achieved.
For this reason, we provide targeted support to both system integrators and end users.
Thanks to a number of targeted services, it is possible to develop a complex system starting from the selection of components available on the market. This aims at creating a system which is able to achieve a specific SIL level.
Last but not least, the development of the applicative software and its consequent validation is an equally important step. Several potential risks for SISs derive from failure management logics or diagnostic capabilities which are ineffective due to programming.
In order to prevent this risk, our specialists provide complete support working side by side with companies to implement the applicative software as accurately as possible from the development phase, by means of targeted tests, to the validation phase.

Why H-ON Consulting:

  • Customized service: adaptable to any extension and complexity, from small stand-alone electromechanical systems to entire systems distributed on site and multi-platform.
  • Single interface for hardware and software: we support companies during the entire procedure, not only with hardware integration, but also with the development and validation of applicative software.
  • We use an internationally recognized certified software for the calculation of each safety function and the verification of the SIL achieved.
targeted solutions for process risk assessment in terms of costs and benefits

LOPA & ALARP Analysis

Are you a process engineer who needs to implement risk mitigation measures with the right compromise between costs and benefits?

LOPA (Layer of Protection Analysis) is a method which starts from the analysis of data collected through different risk analysis techniques and is aimed at quantifying the reduction of residual risk taking into consideration the existing mitigatory measures for a given risk.
This type of analysis is useful to determine the total amount of risk reduction required and evaluate any incremental measures intended to reduce to the minimum the risk connected to a given product or industrial system.
The LOPA method allows to determine the appropriate SIL level for a specific Safety Instrumented Function (SIF) in case a further reduction of the risk is necessary.
For each SIF it is crucial to determine how much the effective risk reduction is proportionate to the economic and technical effort that is necessary in order to reach it. In this respect we carry out a targeted analysis using ALARP (As Low As Reasonably Practicable) techniques.
The exact definition of risk reduction is a decision that is made taking into consideration the compromise between costs and benefits.
Thanks to our proven experience in this field we are able to define the right compromise between costs and benefits for various industrial sectors.

Why H-ON Consulting

  • We have over 10 years of proven experience regarding LOPA & ALARP assessments.
  • We apply fully integrated LOPA & ALARP analysis methods.
