Rigging Up Safety (Continued)

Installing Handrails, Guardrails, Stairs, Walkways, and Ladders

Handrails, guardrails, stairways, walkways, and ladders are installed where they are needed for safety and access. Take a look at the related hazards and solutions for this work.

Potential Hazards:

  • falls from ladders
  • falls or slips from ladders and stairs due to damaged or missing rungs or steps
  • slips or falls on walkways due to debris or uneven surfaces
  • falls from heights
  • falling into the mud pit or mixing tank

Possible Solutions:

  • Follow established procedures and best work practices.
  • Instruct workers on proper procedures for using and installing ladders.
  • Use only ladders in good repair that do not have missing rungs.
  • Do not install stairs with missing or damaged steps. Repair them before installing them.
  • Keep walkways clean and free of debris and tripping hazards.
  • Use proper fall protection.
  • Place guardrails in place prior to working in elevated areas.

Installing the Power System

Installing the power system is usually done simultaneously with setting up the rig floor, because power is needed to operate the equipment. Today there are generally two types of rigs being used on land. A mechanical rig is powered by engines and compounds. An electric rig is powered by engines and generators. This type supplies power to electric motors, which drive the machinery.

All power cords, belts, and chains need to be connected to the machinery from their associated power source. Simultaneously, the fuel lines and tanks need to be hooked up. Then, start the engines.

Potential Hazards:

  • tripping on power cords and hoses
  • slips and falls on slick walking services
  • getting caught in pinch points
  • exposure to chemical hazards
  • being shocked or electrocuted

Possible Solutions:

  • Keep all cords and hoses orderly and clear of walking spaces.
  • Clear and clean all walkways and walking surfaces of slipping hazards.
  • Use caution around all chain and belt pinch point areas.
  • Use proper PPE when working with chemicals.
  • Use proper lockout/tagout/ procedures.

Rigging Up the Circulating System

While one crew finishes preparing the rig floor, another crew might be rigging up the circulating system.

The mud tanks and mud pumps are set into the predetermined location.

The mud lines are then connected and electric cords are strung.

Potential Hazards:

  • being struck by or crushed by equipment being set into place
  • getting caught in pinch points
  • being struck by crane, load, truck or forklift tipping
  • being struck by hammer when connecting mud line unions

Possible Solutions:

  • Keep a safe distance from equipment that is coming together or moving.
  • Maintain a safe distance from all pinch points.
  • Stand clear of workers that may be swinging hammers.

Installing the Auxiliary Equipment

tubulars

All remaining drilling and auxiliary equipment must be set into place and installed where needed.

The catwalk and pipe racks are positioned and the pipe and drill collars are set on the racks.

Potential Hazards:

  • getting struck or pinched by, or caught in between, tubulars being loaded onto racks
  • having feet pinched or crushed when setting up the pipe racks and catwalk

Possible Solutions:

  • Keep a safe distance from equipment that is coming together.
  • Use a tag line to guide the pipe racks and catwalks into position.

Inspecting the Rig

inspections

Perform a complete inspection of the rig before operating. The driller and/or rig superintendent/toolpusher/manager should walk around the entire rig and inspect for:

  • missing or loose pins and bolts
  • equipment guards
  • adequate guard railings
  • proper line and cable placement
  • unclear walkways

Potential Hazards:

  • falling from the rig
  • tripping on power cords and hoses
  • slipping and falling on slick walking services

Possible Solutions:

  • Use proper fall protection.
  • Keep all cords and hoses orderly and clear of walking spaces.
  • Clear and clean all walkways and walking surfaces of slipping hazards.

Rigging Down

After production casing is run and cemented, the rig is taken down and moved to another site. The rigging down process is basically the reverse of rigging up.

The hazards and solutions are similar to those for rigging up.
