Rigging up is the placement and assembly of the rig itself, and preparing it for drilling. This phase involves the use of cranes, trucks, forklifts, and other heavy machinery to position equipment for assembly, offering plenty of opportunities for workers to be hit by moving vehicles or swinging equipment. Assembling the rig. .
Once the rig is built, it’s time for drilling ahead. In addition to the constant risk of being struck by tongs, spinning chain, or pipe, drilling workers also face the possibility of flash fire. Sixteen percent of all oil and gas fatalities are the result of exposure to flash. .
Maintenance is a constant activity on any drilling rig. Inspecting, adjusting, and servicing equipment on every part of the rig brings maintenance workers into contact with all kinds. .
Eventually, the bit or some other piece of the drill string is going to need to be replaced. Removing or replacing pipe from the well is known as tripping, runs the risk of exposing workers. .
Casing is used to line the well hole with pipe longer and bigger in diameter than the drill pipe. Casing operations happen periodically during drilling, with hazards similar to that of.
[pdf] Since 2003, HardRock Infrastructure Services has been taking on the kinds of projects others will not touch. What started with one man, one rig, and a pocketful of credit cards quickly evolved into one of the top providers of horizontal directional drilling (HDD) services in the United States.
