Simultaneous Operations Risk Assessment

Abstract

Simultaneous Operations (SIMOPS) occur when two or more potentially conflicting activities are being executed in the same location at the same time.The present paper describes the SIMOPS risk assessment process carried out during commissioning of new petrochemical complex in order to properly manage additional risks deriving from concurrent activities.The SIMOPS risk assessment was conducted through several dedicated meetings, with participation of multidisciplinary attendees by all project’s involved parties. The resulting hazards were assessed and proper preventive and protection measures identified to reduce the related risks to As Low As Reasonably Practicable (ALARP) level. The mitigation actions were continuously reviewed according to work site progress and their implementation on field was punctually monitored.Thanks to SIMOPS risk assessment process, together with daily implementation of “safety first” program, the project finally reached 65 mil worked manhours without LTI (Lost-Time Injury), a remarkable achievement in this field.
