The engineer will be responsible for creating SIS (Safety Instrumented Systems) and IPL (Independent Protection Layer) implementation plans that stem from these studies, ensuring that all necessary documentation such as P&IDs (Piping and Instrumentation Diagrams), loop sheets, wiring diagrams, and cause & effect matrices are updated accordingly. In addition to the technical responsibilities, the SIS Engineer will manage Management of Change (MOC) processes to implement instrumentation projects identified through HAZOP/LOPA studies.
