NKK To Build $56-Million Offshore Platform Jacket Off Australia

NKK (Nippon Kokan) will build a $56- million jacket for a conventional offshore platform off the northwest coast of Australia. According to NKK officials in New York, the contract was signed with Woodside Petroleum Development Pty. Ltd. of Australia. The company is the operator of a joint venture, which also includes Shell, Broken Hill Proprietary Company, Ltd., British Petroleum, and California Asiatic Oil Company.

This joint venture is conducting oil development operations in Australia.

The offshore platform, one of the largest of its type in the world, will be installed at the North Rankin Gas Field off the northwest coast of Australia. NKK's responsibilities will include steel procurement, fabrication of the jacket, load-out, and tie-down on the seagoing barge for transport to Australia. All the steel materials for the jacket, which will require some 20,000 tons of steel, will be manufactured by NKK. The jacket will be fabricated at NKK's Tsu Works, and will be delivered in April 1982.

The jacket will measure 146.5 meters high (481 feet) —124.5 meters submerged depth (408 feet)—and the rectangular base formed by the eight legs will measure 67.4 meters by 82.9 meters (221 feet by 272 feet).
