In oil and gas, petrochemical, chemical and power facilities, running several activities at the same time is often a necessity. Without proper control, it can also lead to conflicts, unsafe conditions and major incidents. A structured Simultaneous Operations (SIMOPS) framework keeps these overlapping activities safe without compromising operational integrity or personnel safety.
What is SIMOPS?
SIMOPS refers to two or more activities, such as construction, maintenance, drilling, commissioning, start-up or production, being carried out by different teams in the same facility or work area at the same time. They require careful coordination to avoid conflicts and escalation.
Why SIMOPS matters
- Enhances safety. It identifies and mitigates compounding risks from overlapping activities.
- Minimises disruption. It avoids physical and scheduling conflicts between teams.
- Supports compliance. It meets international standards and safety regulations for concurrent operations.
- Optimises resources. It reduces facility downtime by allowing parallel work within defined limits.
Key components of a SIMOPS study
- 1. Activity identification. Classify all normal and abnormal operations in the shared area and identify overlapping activities and hazards.
- 2. Influence assessment. Evaluate external factors such as severe weather, visibility limits and nearby operating facilities.
- 3. The SIMOPS matrix. Use a traffic-light compatibility matrix for concurrent tasks: Green means permitted without special conditions, Yellow means permitted only with specific additional engineering and procedural controls, and Red means strictly prohibited because the risk is unacceptable.
- 4. Control measures. Recommend precautions such as an integrated Permit to Work (PTW) system, dedicated communication protocols and strict operating limits.
What a SIMOPS assessment delivers
- A SIMOPS risk register and risk ranking.
- Defined control and mitigation measures.
- Clear roles, responsibilities and communication protocols.
- An auditable SIMOPS report aligned with HSE requirements, integrated with HAZOP and PTW systems.
