Blue Whale 1, the ultra-deep-water semisubmersible drilling rig, is built by China's largest semisubmersible platform manufacturer, China Yantai CIMC Raffles Offshore. It succeeded in collecting samples of combustible ice in the South China Sea on July 29. This is China's first success in mining flammable ice at sea, showing China has mastered combustible ice mining technology.

Blue Whale 1 is the world's most advanced ocean drilling platform design. The platform has the greatest operating and drilling depth in the world, and can operate in deep-sea operations across the world.
