Simultaneous Operation( SIMOPS) || English Subtitle ||

What Does Simultaneous Operations (SIMOPs) Mean? Simultaneous operations (SIMOPs) are situations in processes where two or more operations or activities occur at the same time and place. They may interfere or clash with each other and may involve risks that are not identified when each activity is considered by itself. Thus, they can increase the risks of the activities or create new risks. Simultaneous operations often involve work in the same area by multiple contractors and subcontractors or multi-disciplinary workers whose work may overlap and/ or interact. For example, construction activities near active equipment such as crane lifts over a storage tank containing a toxic material may result in a release from dropped objects. Similarly, a maintenance activity near another process operation such as hot work in the vicinity of a tank truck unloading a flammable material may result in a fire. A number of major process industry accidents have involved simultaneous operations. Finally take these five steps to ensure that your team has understood the risk of SIMOPS and has put in controls to minimize this risk: No.1 Identify the additional hazards introduced by the SIMOPS No.2 Assess the relevant level of risk No.3 Verify the adequacy of the planned control measure No.4 Identify additional risk reduction measures No.5 Provide input to Permit-To-Work process for embedding additional controls.
