New cell spar technology

Kerr-McGee Corp., along with its partner Ocean Energy Inc., has selected Technip Offshore Inc. to construct the world’s first cell spar for the development of its Red Hawk deepwater field in Garden Banks block 877 in the Gulf of Mexico. First production from this natural gas field with estimated proven reserves of more than 250 billion cubic feet is expected in the second quarter of 2004. Located in 5300 feet of water, Red Hawk will be Kerr-McGee’s deepest development to date. The innovative cell spar, which is the third generation of spar technology, will have an initial daily production capacity of 120 million cubic feet of gas, with ultimate capacity of 300 million cubic feet. It will measure 64 feet in diameter and 480 feet in length. The design includes seven tubes, each 20 feet in diameter, with a centre tube surrounded by the other six tubes, all connected by structural steel. The deck will be 110 feet by 132 feet. Construction is expected to begin in the fourth quarter of 2002.
