Hyundai Heavy Industries delivered Ocean Greatwhite, the world’s largest semisubmersible drilling rig, to Diamond Offshore on July 15.

Diamond Offshore ordered the $630 million, 123 m x 78 m semisubmersible from Hyundai in 2013. The rig is capable of operating in 3 km of water and drilling down to 10.67 km from the sea surface.

BP has chartered Greatwhite for operation in the Great Australian Bight beginning in October.

The delivery installment worth $395 million received from the client will help improve its cash flow, a Hyundai Heavy Industries representative said in the press release. "The close cooperation between Diamond Offshore and HHI on the basis of mutual trust is what made the delivery of Ocean Greatwhite possible."
