China has broken the world record again by building the largest offshore ultra-deep water drilling platform, which is also able to drill to the deepest depths of the sea.

The semi-submersible drilling platform named Blue Whale 1 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. 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.
