Software FMECA approach provides guidance for determining risks, probability of software failure

摘要

FAILURE MODE, EFFECTS AND Criticality Analysis (FMECA) techniques have been standardized in IEC 60812 and referenced in offshore standards, but there is little guidance on how to treat software components during analysis. The methodology presented here aims to improve the reliability of the software-dependent system and reduce costs by providing guidance on how to approach software alongside hardware in the FMECA of software-dependent control systems for the offshore oil and gas industry. Examples of applications on BOP control systems are used to present the software FMECA (SFMECA) approach.
