McDermott International, Inc. (NYSE: MDR) ("McDermott") announced today that its Malaysian affiliate Berlian McDermott Sdn. Bhd. was recently awarded a significant subsea contract for executing a deepwater engineering, procurement, construction, transportation, installation and commissioning project offshore Malaysia. The value of this contract is included in McDermott's first quarter 2012 backlog.

The award is for the subsea infrastructure of the Siakap North - Petai ("SNP") Development Project operated by Murphy Sabah Oil Co., Ltd. ("Murphy"), comprising rigid flowlines, flexible risers, an umbilical and subsea hardware and controls. The SNP field is located nearby the existing Kikeh field, northwest of Labuan Island, Malaysia, in waters 3,900 - 4,900 feet deep.

"Our subsea engineering expertise, fabrication track record at our Batam Island facility, state-of-the-art subsea construction vessels and understanding of the Malaysian market, contributed to this successful award," said Stephen M. Johnson, Chairman of the Board, President and Chief Executive Officer of McDermott. "We look forward to delivering the facilities for this important field development for Malaysia."

The SNP field architecture consists of two rigid, insulated, pipe-in-pipe production flowlines, one rigid water injection flowline and one main umbilical system connecting eight new manifolds and subsea distribution units to existing riser slots on the Kikeh FPSO. The development calls for five water injection and eight production wells, drilled from the manifolds at each of the four drill center locations.

Detailed engineering and procurement for the project are underway, and fabrication of PLETs, jumpers and other installation aids is expected to begin in the third quarter of 2012. Following the infrastructure installation, McDermott will undertake a comprehensive System Integration Test of the subsea units and provide commissioning assistance. The project scope is scheduled to be completed by the third quarter of 2013.
