Drilling Rigs:Oil rig construction is hard work

05.06.2009 · Posted in Science Articles

Oil rig production is a specialized field. You have to have special equipment and specially trained employees. There are two types of drilling rigs, the ones on land and the ones offshore. Both require different equipment and training. Oil rigs can be truck mounted. drilling rigs Can be very large. They have to bore through thousands of feet of dirt. The will have to circulate thousands of pounds of mud with their pumps. The mud is used to keep the drill bit cool. The mud is sent down the drill pipe to the drill bit. This cools the bit and removes the waste material as the oil rig is drilling. The hoists in the rig need to lift hundreds of tons of pipe. Other equipment is used to extract the oil or natural gas later Drilling Rigs. Some remote locations require living courtiers and catering for crews . All of this can be considered part of the constructions. rnrnOcean drilling rigs construction needs to have everything. This includes living space to the equipment required to process the oil. A platform that is fixed is built on steel or concrete legs that are anchored directly into the seabed. The deck of the rig is supported by long legs. The oil deck has room for drilling rigs, oil production facilities and employee quarters.Their is all so a fixed structure called a compliant tower. It has thin movable towers and a piled foundation instead of concrete or steel legs. Semi-submersible platforms have legs with buoyancy tanks or pontoon-like structures. The platform can be moved as need be. They are anchored by cable anchors when not being moved. rnrnJack-up rigs are the most common drilling platform. It has supporting legs that stand on the sea floor. The columns or columns can be moved up and down using a a hydraulics and a motor. When the legs are up the rig can be moved to a new location. At the new position, the legs or columns are moved down until they are on the sea floor. Tension-leg platform is moored using tethers or tendons at each corner. A drilling platform that is on 10% above water is called a spar rig. It uses a single vertical cylinder to support a deck. It works under the same principle a buoy does.Their is a requirement meet by each rig. rnUtilize by above mentioned oil rig construction.
