In high-hazard industries like oil and gas, petrochemicals, and offshore operations, projects often require multiple activities to occur at the same time in close proximity, such as drilling, production, and construction. These Simultaneous Operations, or SIMOPS, introduce unique challenges due to the potential for conflicting activities to create safety, health, or environmental risks. SIMOPS management is a structured approach to planning, coordinating, and executing these activities safely and efficiently. This article explores the principles, methodology, and practical applications of SIMOPS, with insights into how Cormat Group ensures safe and successful operations in complex environments.

What are Simultaneous Operations (SIMOPS)?

Simultaneous Operations (SIMOPS) refer to the execution of two or more independent activities in the same or overlapping areas of a facility, where the activities could interact and create hazards. These operations are common in industries where time, space, or resource constraints necessitate concurrent tasks, such as production continuing while maintenance or construction occurs. SIMOPS management involves identifying potential conflicts, assessing risks, and implementing controls to ensure all activities proceed safely.

SIMOPS are critical in industries governed by regulations like the UK’s Control of Major Accident Hazards (COMAH), OSHA’s Process Safety Management (PSM), or offshore safety standards. For example, on an offshore platform, SIMOPS might involve drilling a new well while maintaining production, requiring careful coordination to prevent gas leaks or equipment conflicts. The goal is to reduce risks to As Low As Reasonably Practicable (ALARP), ensuring safety, health, and environmental protection during complex operations.

Why is SIMOPS Management Important?

Effective SIMOPS management is essential for several reasons:

• Preventing Major Incidents: By identifying and mitigating conflicts, SIMOPS management prevents accidents like fires, explosions, or toxic releases.
• Ensuring Worker Safety: Coordinating activities reduces risks to personnel, such as exposure to hazardous materials or equipment collisions.
• Regulatory Compliance: Regulations like COMAH and PSM require robust risk management for simultaneous activities, with SIMOPS providing evidence of compliance.
• Operational Efficiency: Proper planning minimizes downtime, ensuring concurrent activities don’t disrupt schedules or budgets.
• Environmental Protection: SIMOPS management prevents spills or emissions that could harm ecosystems.
• Stakeholder Confidence: Cormat Group builds trust with employees, contractors, and regulators by implementing thorough SIMOPS processes.

A 2023 report by the Health and Safety Executive (HSE) found that facilities with structured SIMOPS management reduced incident rates during concurrent activities by 35%, highlighting its critical role in high-hazard environments.

Key Components of SIMOPS Management

SIMOPS management is built on several core elements that ensure safe and efficient coordination of concurrent activities:

1. Activity Identification

List all planned activities, such as drilling, production, maintenance, or construction, and their locations, schedules, and resource requirements.

2. Conflict Assessment

Identify potential conflicts between activities, such as shared equipment, overlapping workspaces, or incompatible hazards (e.g., hot work near flammable gases).

3. Risk Assessment

Evaluate the likelihood and consequences of conflicts, focusing on safety, health, and environmental risks, using tools like risk matrices or Quantitative Risk Analysis (QRA).

4. Control Measures

Implement preventive controls (e.g., permit-to-work systems) and mitigative controls (e.g., emergency response plans) to manage risks.

5. Coordination and Communication

Establish clear communication channels and coordination protocols among teams to ensure all parties are informed and aligned.

6. ALARP Demonstration

Demonstrate that risks are reduced to ALARP by balancing the cost of additional controls against safety and operational benefits.

7. Documentation

Create detailed SIMOPS plans, including risk assessments, control measures, and communication protocols, to support compliance and audits.

Methodology for SIMOPS Management

Managing SIMOPS requires a structured, collaborative approach that integrates risk assessment, planning, and execution. Here’s a step-by-step guide:

Step 1: Define the Scope

Identify the activities to be conducted simultaneously, such as drilling and production or construction and commissioning. Define the scope, including locations, schedules, and involved parties.

Step 2: Assemble a SIMOPS Team

Form a multidisciplinary team, including:

• Operations personnel to represent ongoing activities.
• Project managers to oversee new tasks.
• Safety professionals to assess risks.
• Contractors to provide practical insights.
  Cormat Group ensures experienced teams drive effective SIMOPS coordination.

Step 3: Identify Activities and Conflicts

List all planned activities and their details, such as:

• Drilling: Well operations in a specific area.
• Production: Ongoing hydrocarbon processing.
• Maintenance: Equipment repairs or inspections.
• Construction: Installation of new modules.
  Identify potential conflicts, such as:
• Shared resources (e.g., cranes or power supplies).
• Proximity hazards (e.g., hot work near flammable gases).
• Scheduling overlaps (e.g., maintenance during production).

Step 4: Conduct a Risk Assessment

Evaluate risks associated with conflicts, using tools like:

• HAZOP or HAZID: To identify hazards, such as gas leaks or equipment failures.
• Risk Matrices: To rank risks based on likelihood and severity.
• QRA: To quantify risks, like the probability of a fire during SIMOPS.
  Focus on safety (e.g., worker injuries), health (e.g., toxic exposure), and environmental risks (e.g., spills).

Step 5: Develop Control Measures

Propose controls to mitigate risks, including:

• Preventive Controls:
  • Permit-to-work systems to manage high-risk tasks.
  • Isolation procedures to separate incompatible activities.
  • Scheduling adjustments to avoid overlaps.
• Mitigative Controls:
  • Fire and gas detection systems to monitor hazards.
  • Emergency response plans, including Escape, Evacuation, and Rescue (EER).
  • Spill containment measures for environmental protection.
    Link controls to Health, Safety, and Environment Critical Equipment and Systems (HSECES).

Step 6: Establish Coordination Protocols

Define clear protocols for:

• Communication: Use radios, daily briefings, or digital platforms to share updates.
• Authority: Assign a SIMOPS coordinator to oversee activities and resolve conflicts.
• Decision-Making: Establish escalation procedures for unexpected issues.
  Conduct pre-SIMOPS meetings to align all parties.

Step 7: Demonstrate ALARP

Show that risks are reduced to ALARP by:

• Evaluating the effectiveness of controls in mitigating conflicts.
• Conducting cost-benefit analyses of additional measures (e.g., more detectors vs. risk reduction).
• Comparing practices to industry standards or regulatory requirements.
  Document the rationale for accepting residual risks.

Step 8: Develop a SIMOPS Plan

Create a comprehensive SIMOPS plan, including:

• Activity descriptions and schedules.
• Risk assessments and control measures.
• Communication and coordination protocols.
• Emergency response procedures.
  Ensure the plan is accessible to all teams and regulators.

Step 9: Train Personnel

Train workers and contractors on:

• SIMOPS procedures and control measures.
• Recognizing hazards during concurrent activities.
• Responding to emergencies, like activating alarms or evacuating.
  Conduct tabletop exercises or drills to test preparedness.

Step 10: Implement and Monitor

Execute the SIMOPS plan, ensuring all controls are in place. Monitor activities through:

• Daily coordination meetings to address issues.
• Safety inspections to verify compliance.
• Real-time hazard monitoring, like gas detection systems.

Step 11: Document and Validate

Document SIMOPS execution, including incidents, near-misses, and lessons learned. Validate the plan’s effectiveness with stakeholders, including operators, contractors, and regulators, to ensure compliance.

Step 12: Review and Update

Regularly review the SIMOPS plan to reflect changes in activities, regulations, or lessons learned. Conduct post-SIMOPS evaluations to identify improvements for future operations.
