China breaks world record by building largest offshore drilling rig
The semi-submersible drilling platform named Blue Whale 1 was manufactured by Yantai CIMC Raffles Offshore Limited (CIMC Raffles), China Central Television reported.
The rig weighs 42,000 tons with a deck as large as a standard soccer field. At a height of 118 meters, equal to a 37-story building, the platform cost $700 million.
The platform has a maximum operating depth of 3,658 meters and a maximum drilling depth of 15,240 meters respectively, the greatest operating and drilling depth in the world.
It can operate in deep-sea operations across the world, CIMC Raffles says on its website. Its electric cable has a pull extension length of 1.2 million meters.
It is the first "turn-key project," which is completed and can be sold to any buyer, by a Chinese shipbuilder in the ultra-deep water field.
Blue Whale 1 was named and delivered to its project owner based in Yantai, a port city of East China's Shandong Province on February 13.
The platform will be jointly operated by Blue Whale and CNPC Offshore Engineering Co. Ltd for ocean energy exploration according to a previously signed service agreement between the two sides.
