Drilling rig

pipe. [4] Referred to as a float, the NRV is usually driven by a piston. During circulation, drilling fluid forces the valve open against the spring. When pumps are off the valve is closed through a combination of the spring and wellbore pressure.

How would the oceans change without offshore oil drilling? Oceans would be cleaner and would have more organisms. About twenty-seven oil spills occur daily (Nardo) and about twenty-five million gallons of oil spill each year (Yeardley). This is clearly a problem because all the organisms and the environment are in danger. Offshore oil drilling shouldn’t be allowed because it causes oil spills, harms nature, and contaminates water. Offshore oil drilling cause oil spills. Oil spills threaten…

Deepwater Oil Rig Explosion of 2010 On April 20th, 2010 the Deepwater Horizon oil rig located in the Gulf of Mexico, suffered a massive explosion resulting in history’s largest marine oil spill to date. The explosion resulted in an estimated 1,770 kilometers of shoreline being polluted as well as the sinking of the oil rig on April 22nd, 2010 (Pallardy 2015). Transocean, an off-shore drilling company, owned and operated the Deepwater Horizon oil rig, which was leased by British Petroleum (BP).…

High-pressure methane gas from the well expanded into a drilling rig operated and owned by Transocean (support company that specialized in deep water drilling). However, the blowout preventer failed since a flawed well plan did not include enough cement between the 7-inch production casing and the 9 7/8-inch protection casing which was done by Halliburton…

Oil Drilling in Alaska Alaska has a reputation for having one of the most beautiful and bountiful ecosystems America has to offer. However, this time capsule of scenic beauty may be in danger. The Shell Oil Company has plans to drill for oil off the northern coast of Alaska in the Chukchi Sea. It is believed that one fourth of earth's undiscovered oil maybe found beneath its floor. However, drilling could potentially have a negative impact on the environment. The Chukchi Sea is home to an…

needed to weigh and assess in the real world industry. These approaches should be technocratic and democratic depending on the cases. There are many important risks that most mechanical engineering should deal: Pressure vessels, structural failure, oil rig explosion, etc. Engineers must follow the code of ethics and do the right things. Pressure vessels…

Jimmy Carter applies a crafty choice of words in his foreword, beginning with his representation of the wildlife reserve. He mentions how he gazed at the “brilliant mosaic of wildflowers, mosses, and lichens” and reminisced when “the sweep of tundra before [them] became flooded with life.” By pointing out the elegance and allure of the ANWR, he presents the refuge as more than simply mountains and trees. He portrays it as an area with depth, soul, and life, touching the hearts of the audience.…

explosion occurred on a large oil rig, killing many of the workers and the ones that were lucky enough to survive suffered extreme injuries and would never be the same and this event was called the Deepwater Horizon drilling rig explosion. The Deepwater Horizon drilling rig explosion refers to the April 20, 2010 explosion and subsequent fire on the Deepwater Horizon semi-submersible Mobile Offshore Drilling Unit (MODU), which was owned and operated by Transocean and drilling for BP in the…

subdued pumps are used to extract the needed oil. Some of these drilling sites can supply oil for decades to come. Oil platforms are more expensive than oil rigs because of the needed platform structure that must take the abuse of ocean waves and storms. These platforms must contain living corridors for crew and even a helicopter platform. However, the drilling techniques on the platform are generally the same as in onshore drilling. After the oil is collected it must be refined and converted…

comes to oil & gas. The oil companies, who have offshore rigs, need to make sure they have an effective communication with first responders and follow all government regulations to ensure the safety of its employees. The company BP is infamous for the deep-water horizon disaster that happened in 2010, they had multiple chances to prevent this disaster but failed. BP failed to maintained quality standards causing the offshore drilling rig to explode, the first safety quality that was ignore…
