Derrick Equipment Maintenance
Maintenance activities performed in the derrick are critical to the safe operation of the hoisting system. These tasks commonly include lubricating the swivel, traveling block, and crown block, as well as inspecting and replacing swivel packing and other wear components.
Because derrick maintenance is performed at elevation and often around suspended or rotating equipment, it is considered high-risk work. Careful planning, proper isolation of energy sources, and strict adherence to fall protection requirements are essential.
Proper fall protection is critical during derrick maintenance.
Potential Hazards
- Getting caught between moving equipment and fixed objects during maintenance activities.
- Falling from heights while climbing the derrick or working on elevated components.
- Being struck by falling tools, parts, or equipment from above.
- Exposure to pinch points while servicing swivels, blocks, or sheaves.
Possible Solutions
- Follow proper lockout/tagout (LOTO) procedures to ensure equipment is de-energized and cannot move unexpectedly.
- Use approved fall protection systems, including full-body harnesses, double lanyards, and certified anchor points.
- Wear appropriate Personal Protective Equipment (PPE), such as hard hats, gloves, eye protection, and slip-resistant footwear.
- Minimize the number of personnel on the rig floor and in the derrick during maintenance to reduce exposure.
- Secure all tools and equipment with tool tethers or safety lines to prevent dropped-object incidents.
- Establish and enforce exclusion zones beneath elevated work areas.
