The rig, built in 2010, is contracted to Reliance of India under a 10-year deal through 2020 but has been sublet to US supermajor Chevron where it had been drilling the Moccasin prospect in Keathley Canyon Block 736.

Transocean's latest fleet status summary says the rig will remain under contract with Reliance through September of this year at a dayrate of $508,000.
