Walkways: The Unsung Heroes of Drilling & Well Completion
In the often-hazardous world of drilling and well completion, safety is paramount. One crucial element ensuring safe movement of personnel is the walkway. More than just a path, walkways provide a designated and protected route through areas where hazards like equipment, machinery, and open pits abound.
Types of Walkways:
- Elevated Walkways: These walkways are raised above the ground level, providing clear access over potentially dangerous areas. They are often found near drilling rigs, production platforms, and wellheads, allowing personnel to safely move between different areas and equipment.
- Ground-Level Walkways: These are typically constructed from metal grating or solid platforms placed at ground level. They serve as a designated path around equipment or machinery, ensuring that personnel don't inadvertently step into hazardous areas.
- Temporary Walkways: These are often used during specific operations, such as well completion or maintenance. They can be made from a variety of materials, including plywood, steel planks, or even scaffolding.
Key Features of Effective Walkways:
- Strength and Stability: Walkways must be strong enough to support the weight of personnel and equipment. They should be securely anchored and built with materials resistant to corrosion and wear.
- Clearance: Adequate clearance must be maintained around walkways to prevent obstructions and ensure safe movement.
- Illumination: Good lighting is crucial, especially in low-light conditions or at night, to enhance visibility and prevent accidents.
- Non-Slip Surfaces: Walkway surfaces should be designed to provide a secure grip, even in wet or oily conditions.
- Handrails and Guardrails: Handrails and guardrails are essential for safety, especially on elevated walkways. These provide support and prevent falls.
- Access Points: Walkways should have clearly marked access points and exits, allowing personnel to navigate safely.
Beyond Safety:
- Efficiency: Walkways streamline operations by providing clear routes for personnel, equipment, and materials. This reduces the risk of delays and accidents, leading to improved efficiency.
- Organization: Walkways help to organize the work area, making it easier for personnel to navigate and understand the layout. This can be especially important in complex drilling or well completion operations.
Conclusion:
Walkways are often an unseen but essential element of drilling and well completion operations. By providing safe and organized access, walkways contribute significantly to worker safety, operational efficiency, and the overall success of any drilling project.

Walkway Exercise
Instructions:
You are the safety officer on a drilling rig. You notice a newly constructed walkway leading to the wellhead has a missing handrail on one side.
Task:
- Identify the safety hazard posed by the missing handrail.
- Describe the immediate actions you should take to address this hazard.
- Explain the potential consequences of failing to address this hazard.
Exercice Correction
1. **Safety Hazard:** The missing handrail poses a significant fall risk for workers navigating the walkway, especially when carrying equipment or materials. This increases the likelihood of serious injuries or fatalities. 2. **Immediate Actions:** * **Stop work:** Immediately stop any activity requiring personnel to use the walkway. * **Isolate the area:** Place warning signs and barriers around the unsafe section of the walkway to prevent unauthorized access. * **Contact the supervisor:** Inform the supervisor or relevant personnel about the hazard and the need for immediate repair. * **Implement alternative access:** If possible, establish a temporary alternative access route, ensuring its safety and proper signage. 3. **Potential Consequences:** * **Injuries:** Workers could suffer falls, leading to fractures, sprains, head injuries, or even death. * **Legal liability:** The company could face legal consequences due to negligence and failure to provide a safe working environment. * **Operational delays:** The work stoppage necessary for repairs would cause delays and disrupt the drilling operations. * **Reputation damage:** A serious incident could damage the company's reputation for safety and professionalism.
