South Korea: Atwood Oceanics Enters Drillship Construction Contract with DSME

ATWOOD OCEANICS, INC., announced that on October 15, 2011, Alpha Eagle Company, a wholly-owned subsidiary of Atwood Oceanics, Inc., entered into a turnkey construction contract with Daewoo Shipbuilding and Marine Engineering Co., Ltd., (“DSME”) to construct an ultra-deepwater drillship, to be named the Atwood Achiever, at the DSME yard in South Korea.

The Atwood Achiever is expected to be delivered by June 30, 2014 at a total cost, including project management, drilling and handling tools and spares, of approximately $600 million. Financing for the construction of the Atwood Achiever is expected to be provided from a combination of available cash, cash flows from operations and borrowings, as necessary, from the current senior credit facility of Atwood Offshore Worldwide Limited, a wholly-owned subsidiary of the Company. Upon delivery, the Atwood Achiever will become the sixteenth mobile offshore drilling unit owned by the Company.

Rob Saltiel, President and CEO, commented, “We are pleased to execute our option with the DSME shipyard to build the Atwood Achiever and to expand further our high-specification, ultra-deepwater drilling fleet. This rig’s state-of-the-art design, coupled with the benefits of identical outfitting to the Atwood Advantage, make it a compelling investment for Atwood Oceanics.”

The Atwood Achiever will be identical to the previously ordered Atwood Advantage and will be a DP-3 dynamically-positioned, dual derrick ultra deepwater drillship rated to operate in water depths up to 12,000 feet and drill to a depth of 40,000 feet. The Atwood Achiever will also have enhanced technical capabilities, including a 7-ram blowout preventer, three 100 ton knuckle boom cranes, a 165 ton active heave “tree-running” knuckle boom crane, and 200 person accommodations.

This order comprises the execution of the first option retained by the Company. The Company also secured modifications to the one remaining priced option to construct an additional ultra-deepwater drillship, which requires commitment by July 31, 2012. The Company has made no determination at this time on whether the option will be exercised.
