Drilling rigs are large machines used to create holes in the ground for various purposes, such as extracting oil, gas, or minerals. They consist of several components, including a drill bit, a derrick, and a power source. The drill bit is the part that actually penetrates the earth, while the derrick supports the drilling equipment and helps lift heavy materials. These rigs can be found on land or offshore, with offshore drilling rigs being specifically designed to operate in ocean waters. Safety is a top priority in drilling operations, as workers must manage risks associated with high-pressure environments and potential spills.
