China’s first deep-water drilling platforms to create a number of the first in the world (Figure)
“marine oil 981 panoramic.
Voice of China “News Coverage,” reported, “Yesterday, the China National Offshore Oil 981 platform in the South China Sea drilling success, the Chinese oil company’s first independent deepwater oil and gas exploration and development, marking the China National Offshore Oil The deep-water industrial strategy has taken a substantial step. At the same time, the situation in the South China Sea wells will therefore change.
“Offshore Oil 981″ drilling platform, representing the world’s most advanced level of the sixth generation deepwater drilling semi-submersible platform. this platform is 114 meters long, 89 meters wide, which is equivalent to the size of a standard football field; height of 117 meters, equivalent to 45 storeys high in the 3 km under the deep sea, call a 10 000-meter-deep wells, exploitation of oil resources embedded in the depths of the ocean.
then this monster up to dozens of storey, is how to run, but also how to ensure the safe.
Wang Yilin: I declare, Offshore Oil 981 deep-water drilling platforms, drilling
With China’s CNOOC chairman Wang Yilin “spud” the order , live large screen display, deep-sea robot shooting a picture of the drilling catheter into the formation. few minutes later, the 981 platform to send information back, Liwan 6-1-1 oil drilling drilling, well-functioning, such an important mining platform why the name? in digital Cao Shujie, vice president of China Oilfield Services Limited, told reporters, in fact, the China National Offshore Oil 981 platform is named like a password, each number has its own meaning.
Mr Cao : The earliest Corporation “9″ row of this figure is drilling series, which is “9″, then “8″ was said to be deep water, so the word starts with, and then “1″ is the first one, that is, such a row 981
As 981 origin of the name used for drilling deep-water mining ship “, it has the drilling, completion and workover operations and other functions, the maximum operating depth of 3000 m, drilling depth up to 10,000 m, representing the highest level of today’s technology of the world’s offshore oil drilling platform, has created a number of world records. not only could withstand 200 years of a typhoon, but also effectively prevent the occurrence of similar to the Gulf of Mexico accident. China Jiang Weixin, deputy chief engineer and general manager of Drilling and Completion Technology Management Department of the National Offshore Oil Corporation, is the world’s highest level of safety factor here, common of the three control methods ranging the world.
Jiang Wei: its control work on the deck above can achieve the closure of the wellhead, and the second on the platform there is a set of sonar remote control device, that is if the person is not in the platform, next to the vicinity of the tugboat, sonar, remote shutdown, shutdown is underwater robotics, and go after the valve to implement shutdown, which is the world’s three methods of work.
more important, the platform used for the first time the world’s most advanced intrinsically safe underwater blowout preventer system: standing next to the half of the 981 platform underwater blowout preventer, Jiang Weixin, pointing to the heavy 330 tons, 13 m high white cylindrical building, proud to say that the 981 platform, the addition of a control system
Jiang Wei: 981 the addition of a set is the Gulf of Mexico, the problem ourselves, our country is also the world’s first adopted in the case of no power control, fluid control pressure, which can turn off without underwater robots, and without sonar, they do not go up in the deck manipulation it, I want to turn off, to open, not as long as there is no signal, and shut himself off.
drilling platform, a total of five, regardless of stand in which a layer of which one corner, the reporter feel are like a general on land, at the gym, some employees are to exercise in the office area, a computer being skilled operating with, if you do not look out the window, high wind and waves, you would never think that they are in extremely poor geological conditions of the the South China Sea embrace. CNOOC Chief Technical Adviser, Chinese Academy of Engineering, Zhou Shou told reporters, forming an important reason of all is the 981 platform has a strong “heart” – a powerful engine, the stability of the platform is a great deal of assurance.
weeks as follows: such equipment, its power to 40,004 over 1000 kilowatts, equivalent to the generating capacity of a medium-sized cities, is a well-equipped with the power of a city. automatic positioning of the helix, propeller, this propeller is equivalent to five locomotives pull a total of eight propeller, eight thrusters.
have technical guarantee 981 platform will play the role of security of energy strategy is self-evident: In recent years, China’s energy supply and consumption of contradictions become increasingly prominent: dependence on foreign oil reached 56.3 percent last year to 21.5 percent, natural gas dependence on foreign, with China’s industrialization process steadily, and expected future oil and gas dependence on foreign will further enhance But in the past, but the harsh natural environment, the development of technical difficulties, high cost and other reasons to limit our country has been only stay in the 300 meters in shallow water operations. </p
Jiang Wei: 981 deep-water drilling platform built and put into use, the marks of deep-water equipment capacity, operating capacity to achieve development by leaps and bounds, one step from 300 m to 3000 m, this is our first port official operations, taken a substantial step self deepwater exploration wells, marked self-deepwater exploration and deep-water strategy.
