SDRL

Seadrill Ltd

An offshore drilling contractor that rents out a fleet of modern drillships, semi-submersibles, and jackups to oil giants like Petrobras on a daily rate, working in waters up to 12,000 feet deep. Norwegian-born shipping tycoon John Fredriksen launched the company in 2005 in Bermuda, and it grew fast by buying up rivals like Smedvig. Its name is a simple mash-up of "sea" and "drill" — exactly what it does.
