Offshore oil rigs are big machines for getting oil from beneath the ocean floor. They have special machinery that assists the rigs in drilling deep into the earth to extract the valuable oil under the ground.
Drilling is one vital technology applied in offshore oil production. That means using a very large drill to drill through rock and dirt to extract the oil. The bit is attached to a long pipe that rotates, courtesy of powerful machines on the rig. As the bit turns, it crushes the rock, creating a hole that allows the oil to flow to the surface.
When the oil is found, the oil is pumped up to the surface with pipes. These pipes take the oil from the well into storage tanks on the rig, where it is readied to be sent to shore. It takes a great deal of energy to pump oil to the surface, explaining why offshore drilling rigs contain large engines to run the process.
In addition to oil, offshore oil rigs also extract natural gas, which is frequently found along with oil. The oil and gas are parted through gas processing. That means the gas is compressed and scrubbed before it is piped to shore.
Those oil rigs offshore are remarkable structures built to take the battering of the ocean. They are constructed to be extremely strong and stiff, and to be able to take large storms with strong winds. Rigs sit on platforms made of steel and concrete that are held in place by sturdy mooring systems attached to the ocean floor.
They are very important in the oil and gas industry because they allow us to get the resources we need. Without these machines, there would be no way to get to the oil and gas that keeps our homes, cars and businesses going.
Today’s gas and oil rigss are always improving to be faster and cheaper to work. New technologies are in the works to assist the drilling be faster and more precise as well as friendly to the environment. These innovations — from automated drill systems, to sensors and robotics — promise to make offshore oil extraction safer and more sustainable.
