International standards IEC 61508 and IEC 61511 set out practices that ensure the safety of an industrial process through the use of instrumented systems. The standards help to determine whether instrumented systems are necessary, which tasks they should perform, how reliable they should be and how to produce, install and maintain them. ENCONET provides expert support in the implementation of the standards IEC 61508 and IEC 61511, mainly in risk assessments (HAZOP), SIL determination studies (LOPA), safety requirements specifications (SRS) and SIL verification calculations. In addition, ENCONET provides expert support in the establishment of the functional safety management systems and in the organization of verifications and validations.
