MODERN DRILLING CONCEPT
This concept drilling method is a great improvement over the present technology.
Currently while drilling takes place if there is a leak it will flow directly into the sea causing environment pollution.
This concept as shown in the diagram has two dome shaped protection walls made of concrete or hard metal. The outer layer keeps sea water out. The inner layer collects any leakage and when the drill is being removed oil may escape into the outer layer, in which case the motor pump inside the inner layer will pump it back into the inner layer.
This also helps the workers repair faster beneath the sea and every time there is any leakage during drilling the sea environment will be protected.
