Deep Down, Inc. announced that it has received an executed $11.1m contract from Delba Drilling International Cooperatie U.A. to supply and install the deepwater marine drilling riser flotation system for the new-build Delba III semisubmersible drilling rig. The original letter of intent, initially estimated at $9m, was received May 23, 2008. The increase in the value of the contract is reflective of engineering changes to satisfy additional lift requirements. The Delba III semisubmersible drilling rig is rated to drill in 7,874 ft of water and is readily upgradeable to 8,858 ft. The Delba III has long-term contracts to drill in Brazilian waters. The rig set of flotation for the Delba III is scheduled to be delivered by early 2010.
