Business Wire

HOUSTON -- November 05, 2012

McDermott International, Inc. (NYSE: MDR) (“McDermott”) announced today that
one of its subsidiaries has recently been awarded two projects by Saudi Aramco
in the Abu Safah, Marjan and Safaniya fields in the Arabian Gulf.

The two projects consist of six topsides and a bridge that connects to the
existing Marjan facilities. In addition, the project will require other
associated modifications and brownfield work. The combined total weight of the
structures will exceed 4,000 metric tonnes.

The North Dome project, which was issued under the existing Long Term
Agreement and is included in McDermott’s third quarter 2012 backlog, comprises
procurement, construction and installation of two wellhead decks for Abu Safah
and Marjan, and an auxiliary platform and access bridge for Marjan.

The second project, also issued under the existing Long Term Agreement, was
included in McDermott’s 2012 second quarter backlog and comprises procurement,
fabrication, transportation and installation of three electrified production
deck modules (PDM’s) in the Safaniya and Marjan fields. McDermott’s Jebel Ali
fabrication facility will construct the platforms, while vessels from
McDermott’s global fleet will be used to install the facilities.

“We will be executing both projects using engineering, project management and
procurement resources from our Al-Khobar, Saudi Arabia office. Our In-Kingdom
activities continue to grow as we ramp up this Engineering office and our
recruitment efforts, to position McDermott for current and future project
requirements,” said Stewart Mitchell, Senior Vice President and General
Manager, Middle East, Caspian and North Sea for McDermott.
