A model of world's biggest deep water semi-submersible drilling rig with dual drilling towers, produced by Yantai CIMC Raffles Offshore Co, was displayed at an exhibition held by China's equipment and manufacturing industry in Rio de Janeiro, Brazil on May 20.

The model caught the eyes of Premier Li Keqiang, who paid a visit to the exhibition on that day.

The drilling rig, called the D90, is still under construction. When finished, it will have an overall length of 122.5 meters and a width of 92.7 meters. As one of the seventh generation of ultra-deep water semi-submersible drilling rigs, it will be equipped with a DP3 dynamic positioning system and will adopt the latest technologies to improve safety and production efficiency. The rig can resist winds of up to 117 km per hour.

Upon completion, the rig will be the world's most advanced. It will feature the deepest vertical drilling depth and will be able to be operated in 95 percent of deep water areas around the world, such as South China Sea.

Yantai CIMC Raffles Offshore Co is China's leading offshore engineering manufacturer and is a subsidiary of the China International Marine Containers Group. The company is building two drilling rigs of this kind, which are scheduled to be delivered in 2016 and 2017 respectively.

"Brazil boasts rich oil and gas resources, which indicates its huge demand for high-end offshore engineering equipment. As a leading enterprise in marine equipment manufacturing in China, CIMC is striving to seek cooperation with Brazilian enterprises on deep sea drilling rigs," said Yu Ya, president of CIMC Raffles.

To date, two of CIMC's deep sea semi-submersible drilling rigs have been performing well in sea areas of Brazil.
