Maintenance Activities

Proper maintenance prevents premature equipment failure, which may cause injuries or fatalities. Drilling equipment is subjected to stress and vibration during operations. Maintenance is a necessary and ongoing activity on the drilling site.

Maintenance activities include maintaining the:

  • rig floor
  • drilling line maintenance
  • wire rope maintenance
  • mud circulating system
  • generator, electric motors and electrical systems
  • engines
  • derrick equipment maintenance

Now, let’s take a closer look at these specific activities on the drilling site.

Rig Floor Maintenance

Maintenance activities include inspecting, adjusting, and servicing on equipment such as drawworks, rotary, catheads, tongs, air hoists, and wire rope.

Potential Hazards:

  • slips, trips, and falls
  • being caught in chains or other moving equipment
  • getting fingers and hands pinched in machine guards or covers
  • receiving sprains and strains

Possible Solutions:

  • Wear personal protective equipment (such as hard hats, work gloves, safety shoes, and eye protection).
  • Be aware of the slipping and falling hazards when performing maintenance on the drilling floor.
  • Keep all work areas clean and clear of oil, tools, and debris.
  • Use non-skid surfaces where appropriate.
  • Use proper lockout/tagout procedures.
  • Seek assistance when moving awkward and heavy guards and covers.
  • Maintain all machinery free of leaks by regular preventive maintenance and repairing when necessary.

Drilling Line Maintenance

A drilling line is a wire rope hoisting line, reeved on sheaves of the crown block and traveling block (in effect a block and tackle). The primary purpose is to hoist or lower drill pipe or casing from or into a well. It must be inspected, slipped and cut regularly.

Potential Hazards:

  • receiving injuries to face and eyes from flying chips of metal when slipping and cutting the line
  • being caught in moving equipment
  • slips, trips, and falls
  • being struck by drilling line

Possible Solutions:

  • Use proper lockout/tagout procedures. [29 CFR 1910.147]
  • Wear proper personnel protective equipment when cutting line.
  • Attach a red flag or other warning device to the drawworks clutch lever as a reminder to the driller whenever the crown safety device is moved or deactivated to allow the traveling block to be raised above the the preset stopping point.
  • Secure drilling line ends prior to cutting.

Wire Rope Maintenance

Wire rope is a cable composed of steel wires twisted around a central core of fiber or steel wire to create a rope of great strength and considerable flexibility. Maintenance activities involved with wire rope include visually inspecting wire ropes daily or per maintenance schedule.

Potential Hazards:

  • getting cuts from the wickers or loose strands on the rope
  • receiving injuries to face and eyes from flying chips when cutting wire rope

Possible Solutions:

  • Wear proper personnel protective equipment when cutting wire rope.
  • Seize wire rope before cutting.

Mud Circulating System

Maintenance activities involved with the mud circulating system include inspecting, adjusting, servicing on equipment such as mud pumps, hoses, hose connections, pop-off valve, shale shakers, belts, and guards.

A mud pump is a large, high-pressure reciprocating pump used to circulate the mud on a drilling rig. A typical mud pump is a two or three-cylinder piston pump whose replaceable pistons travel in replaceable liners and are driven by a crankshaft actuated by an engine or a motor.

Potential Hazards:

  • being caught between, or struck by equipment
  • slips, trips, and falls
  • receiving a foreign body or fluid in the eye
  • burned by fluid contact
  • drowning in mud tank/pit
  • receiving strains and sprains

Possible Solutions:

  • Use proper lockout/tagout procedures.
  • Wear personal protective equipment (such as hard hats, work gloves, safety shoes, and eye protection).
  • Be aware of the slipping and falling hazards when working on the mud circulating system.
  • Provide guardrails and guards around mud tanks.

Electric Generators, Motors and Systems

When conducting maintenance on electrical equipment and systems, make sure that:

  • Electrical connections and power cords are checked for wear for deterioration and replaced if needed.
  • Electric motors are serviced at recommended intervals.
  • All guards are present and correctly installed.
  • Motors electrical connections need to be kept sealed.

Potential Hazards:

  • receiving flash burns or shocks when servicing motors, generators, and breaker panels
  • being caught on moving equipment

Possible Solutions:

  • Do not wash down generators, electric motors and breaker panels with water hose.
  • Avoid wearing jewelry.
  • Do not stand directly in front of breakers when operating.
  • Use dielectric mat in front of control panel or breaker panel.
  • Use proper lockout/tagout procedures.
  • Wear appropriate personal protective equipment.
  • Cover with appropriate shields or guards all exposed revolving parts such as belts, flexible drives, generators, shafts and other moving parts to prevent contact and injury.

Engines

Engines require maintenance and servicing at recommended intervals.

Potential Hazards:

  • getting burned by hot fluids or engine parts
  • being caught in moving equipment or moving parts
  • being cut while working on engines

Possible Solutions:

  • Wear appropriate personal protective equipment.
  • Let engine cool down before working on it.
  • Use proper lockout/tagout procedures.
  • Cover all exposed revolving parts with appropriate shields and guards.

Derrick Equipment Maintenance

Maintenance activities in the derrick consists of lubricating the swivel, traveling block, and crown block, and replacement of swivel packing.

Potential Hazards:

  • getting caught between equipment and objects
  • falling from heights
  • being struck by falling tools or equipment

Possible Solutions:

  • Use proper lockout/tagout procedures.
  • Use appropriate fall protection.
  • Wear appropriate personnel protective equipment.
  • Minimize the number of personnel working on the rig floor.
  • Tie off tools.
