Transocean claims record sea depth for oil drilling
Offshore oil drilling group Transocean claimed Tuesday that it had a set a world record for deep water drilling at an ocean depth of 3,107 metres (10,194 feet) off the coast of India.
The depth was achieved by the ultra-deepwater drillship Dhirubhai Deepwater KG2, surpassing the previous record of 10,011 feet, also set by Transocean in 2003 in the Gulf of Mexico, the group said in a statement.
It set "what the company believes is a world record for the deepest water depth by an offshore drilling rig of 10,194 feet of water while working for Reliance Industries offshore India."
Transocean owned the BP-leased Deepwater Horizon rig that exploded last year in the Gulf of Mexico, killing 11 rig workers and triggering a huge spill along the southern US coast.
By comparison North Sea fields have been largely exploited at water depths of around 100 metres.
