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
, 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
Simultaneous Operations (SIMOPS) is the execution of two or more tasks by two or more functional groups on
the same location at the same time.
In the Oil&Gas and Petrochemical industries SIMOPS takes place specifically when activities from
construction, commissioning, start-up and production operations are being carried out simultaneously. In this
regards, in addition to hazards
concerned to each single task
, additional risks can be generated due to
simultaneous execution in the same area.
In order to identify potential hazards and to eliminate, minimize or managed the
risk associated with SIMOPS
dedicated risk assessment process shall be put in place involving all project actors, typically: plant owner,
project management consultant (PMC), main contractor, subcontractors and vendors.
