A subsidiary of Atwood Oceanics has received a charter contract for a drilling unit from Hess Corporation.

Under the terms of the contract, Atwood Condor, an ultra-deepwater, semi-submersible drilling unit, will be used to drill in the Gulf of Mexico.

The unit, which is being built at Singapore’s Jurong Shipyard, will be delivered in June 2012.

The charter period is for 21 months and includes two one-year options, with pricing subject to mutual agreement.
