"The completion of Devils Tower is yet another major benchmark for the J. Ray McDermott team," said Bob Deason, president and chief operating officer of J. Ray. "It is the second of three spar projects that we have delivered successfully to our clients over the past several months, with the third project, Front Runner, slated for completion later this year. As each of these projects comes to a close, J. Ray solidifies its position as a premier provider of offshore solutions in our industry."
The design of the Devils Tower facility, consisting of hull, mooring system, topsides and production facilities, utilized proprietary technology designed to provide operators with leading edge development solutions in water depths of up to 9,000 feet. The hull, which was constructed at J. Ray's Batam Island, Indonesia facility, is 586 feet in length, 94 feet in diameter and weighed over 11,000 tons at the time of installation. The topside, which weighs over 9,300 tons (maximum payload, including drilling rig), was prefabricated in subassemblies at J. Ray's Veracruz, Mexico facility, then assembled and outfitted at its Harbor Island facility near Corpus Christi, Texas. The platform mooring piles and production riser buoyancy can systems were also fabricated at J. Ray's facility in Mexico.
J. Ray completed the offshore lift and set of the topsides on Nov. 30, 2003, utilizing its Derrick Barge 50 and Shearleg crane with a combined lift capacity of over 7,000 tons. J. Ray also conducted the hookup and commissioning of the platform.
