SIMOPS – Simultaneous Operations Management
Ensuring Safe Coordination of High-Risk Activities in Complex Environments
Introduction
Simultaneous Operations, or SIMOPS, refer to two or more potentially conflicting activities carried out concurrently within the same geographical or operational area. In high-hazard environments—especially offshore oil and gas platforms and during drilling and production—SIMOPS pose unique risks that require meticulous planning, cross-discipline coordination, and barrier-based safety management.
At Apex Process Safety Solutions, we bring deep expertise in managing SIMOPS for:
- Offshore platforms
- Construction campaigns
- Drilling and workover operations
- Production restart
- Hot work near live systems
- Logistics such as crane operations and helicopter movements
Why SIMOPS Matters
Improper SIMOPS management can result in:
- Escalation of hazards due to interacting operations (e.g., hot work near hydrocarbon systems)
- Increased exposure to flammable/toxic releases, dropped objects, confined space hazards
- Loss of control or communication breakdowns between teams
- Major accident scenarios, particularly offshore or in congested environments
Typical Offshore SIMOPS Scenarios
Examples of SIMOPS on offshore platforms include:
- Drilling and production happening simultaneously on the same platform
- Hot work (e.g., welding) during production
- Crane operations near process decks or flares
- Concurrent well intervention, wireline, and coiled tubing jobs
- Live-plant maintenance or tie-ins
- Construction/expansion on FPSOs or fixed platforms during operations
- Helicopter movements while deck operations are ongoing
