HOUSTON -- McDermott International, Inc. (NYSE:MDR) ("McDermott") announced today that a subsidiary of J. Ray McDermott, S.A. ("J. Ray") was recently awarded two new contracts to provide installation services. Both awards are part of field development activities by India's Oil and Natural Gas Corporation Ltd. ("ONGC").

This project is part of ONGC's Vasai East Development expansion of the Bassein East oil field situated east of the existing South Bassein gas field, 50 miles north-west of Mumbai. Projects of this type are typically valued at over $35 million. Installation will be carried out in the last quarter of 2007, by one of J. Ray's derrick barges.

The four wellhead platforms will be installed in an average water depth of 200 feet. Three of these platforms, NEA, NHA and N2A, will be installed in the Mumbai High field, and the fourth platform, BF, will be located in the Bassein field. All jackets consist of 64" and 66" diameter main piles. J. Ray will also install three bridges to connect the existing platforms to the new well heads.
