HOUSTON, Nov. 01, 2017 -- McDermott International, Inc. (NYSE:MDR) announced today a letter of award for a significant* contract for the engineering, procurement, construction and installation (EPCI) services for an offshore Middle East redevelopment project.

McDermott plans to fabricate and install four wellhead topsides, a manifold platform and jacket together with associated subsea pipelines and brownfield tie-in works.

“McDermott has been working in the Middle East region for 54 years and has a proven track record of executing complex offshore projects with certainty. The award of this redevelopment contract is a strong testament to our ability to combine the right offshore assets and superior execution strategy,” said Linh Austin, McDermott Vice President, Middle East and Caspian.

McDermott has a long-standing relationship with this client and vast experience in this field. This award builds on the successful delivery of four jackets in 2016 as part of an earlier phase in the redevelopment project.

Fabrication work is expected to begin in the third quarter of 2018 and offshore installation is planned to begin in the second quarter of 2019. The contract award is expected to be reflected in McDermott’s 2017 fourth quarter backlog.
