Diamond Offshore Drilling, Two New-Build Drillships

Diamond Offshore Drilling, Inc. (NYSE:DO) today announced that a subsidiary of the company has entered into two term drilling contracts with Anadarko Petroleum Corporation. The contracts, which will utilize Diamond Offshore's two new-build drillships now on order, are expected to generate combined maximum total revenue of approximately $1.8 billion and represent 10 years of contract drilling backlog. In addition, Anadarko and Diamond have mutually agreed to dismiss all claims related to the Ocean Monarch.

The dynamically positioned, ultra-deepwater drillships, Ocean BlackHawk and Ocean BlackHornet, are each contracted for five years commencing in late 2013 and early 2014, respectively. As previously reported, Hyundai Heavy Industries Co., Ltd. is currently preparing to commence construction of the two drillships at its South Korean shipyard.

Diamond Offshore President and Chief Executive Officer Larry Dickerson said: "We are pleased to place our newest rigs under contract with Anadarko, with whom we have had a successful long-term relationship. We look forward to contributing to Anadarko's exploration and development efforts, working to bring to market energy resources for the world's increasing demand. A first class customer, two state of the art rigs and Diamond Offshore's high operational standards are all part of a formula for success."

Diamond Offshore provides contract drilling services to the energy industry around the globe and is a leader in deepwater drilling.

Maximum contract revenue as stated above assumes 100% rig utilization. Generally, rig utilization rates approach 95-98% during contracted periods; however, utilization rates can be adversely impacted by additional downtime due to unscheduled repairs and maintenance.
