Short Desciption:
This paper details the process in which the HAZOP / SIL study is conducted. The first part indicates the steps involved and later an example illustrates the steps.

Traditionally, a Hazard and Operability (HAZOP) study and Safety Integrity Level (SIL) Assessment or SIL determination (usually using the Risk Graph or Layer Of Protection Analysis (LOPA) methodology) are two separate facilitated sessions, which produce two unique databases. SIL Validation is yet a third requirement of the International Electro technical Commission (IEC) 61511 standards that demands the use of another set of tools and produces a third database. Trying to manage the recommendations of these interconnected studies is extremely difficult. In the Integrated Approach, only one facilitated session is required for HAZOP and SIL Assessment. Only one database is created, and it is used to perform SIL Validation. In addition to being a secure and auditable database, this single database is also part of a complete “handover package” that operators need to ensure they maintain the SIL integrity assigned to each SIL loop. Some demonstrated benefits of the Integrated Approach are a minimum 30% time and costs savings; a single auditable database; elimination of mathematical errors during SIL Validation; creation of a complete electronic handover data package and the capability of operators to easily model proposed changes to their maintenance and testing plans (SIL Optimization) using the same database.
