Oilfield Operations - Rigging Up

Performing maintenance, or preparing to commence drilling or work over, is a prime time for accidents to happen. The following safety tips should be observed when rigging up a work over or drilling rig.

1. Once the substructure is positioned, be sure the engines are arranged so that the mufflers and exhaust can be directed away from the rig floor. It is important to understand the direction of the prevailing winds, so as not to create a breathing hazard.

2. While complete guarding is not possible at all times during rigging up, keep open floor holes covered when not in use. Hand rails should be installed as soon as possible.

3. The traveling block should be strung while on the derrick floor.

4. Where required, only high pressure fittings in good condition should be used. Relief lines should be exhausted over the mud pits. Always secure mud lines and jets in a manner that will eliminate whipping due to high pressure surges.

5. Make sure that lighting is adequate. This is necessary wherever people will be working on the rig floor and in the derrick.

6. Before anyone is positioned in the derrick, an emergency escape line needs to be provided. The line should be fastened to the girt just above the working platform and should be anchored about twice as far from the rig base as the distance from the ground to the monkey board. The escape trolly should be of sufficient strength and have a braking device.

7. Be sure to keep walkways free of skids and other items which may cause a trip and fall exposure.

8. While rigging up, inspect all chains, hooks and cables before using. If the equipment appears worn or frayed, inform the driller or tool pusher so that it can be repaired or replaced.

9. At all times, avoid working or walking beneath a suspended load.

10. Avoid shortcuts, such as riding the blocks. At all times, access to the derrick should be by way of the ladder, with the employee secured by a harness or safety belt and the lanyard attached to the derrick climber assist.
These are but a few of the common sense rules that must be followed when working around drilling and work over rigs.

Most of all, supervisors and seasoned hands need to watch out for the inexperienced roustabout or floor hand. This individual is new to the oil patch and will be heavily dependent upon other members of the crew for guidance.
