It features a maximum displacement of 70000 tons, maximum operating water depth of 12000 feet (3658 meters), drilling depth of 50000 feet (15250 meters) and dual top drives load of 1250sh.tons. Besides, it is equipped with DP3 dynamic positioning system. This platform is classified by Norway Classification Society. It boasts of an efficiently-designed space and a convenient maintenance access, and for the first time, employs DP3 enclosed circle design, detritus cabin processing and storage system as well as a ballast water treatment system. What is more, due to its NOV hydraulic dual towers design, its production efficiency will be highly improved on the basis of security guarantee. This drilling rig is operational in multi deepwater areas, such as the Mexico Gulf, the China South Sea, Australia, the Brazil Sea, West Africa and the South Atlantic.
