  McDermott Signs Shipyard Contract for Construction of Deepwater S-Lay Vessel

Business Wire

HOUSTON -- December 27, 2012

McDermott International, Inc. (NYSE: MDR) (“McDermott”) announced today that
one of its subsidiaries has signed a contract for the design and construction
of a new high-spec, highly capable dynamically-positioned combination S-Lay
vessel with a 2,000-ton crane.

The vessel, tentatively named Derrick Lay Vessel 2000 (“DLV2000”), will be
constructed at Keppel Singmarine in Singapore and is expected to take approx
2.5 years to build.

“DLV2000 is expected to address a market demand we consider to be extremely
robust for deepwater pipelines as well as our traditional markets,” said
Stephen M. Johnson, Chairman, President and Chief Executive Officer. “A
combination heavy lift and deepwater S-Lay pipelay vessel is an important
asset for our expanding fleet, focusing on the subsea construction market.”

Developed by Keppel’s ship design arm, Marine Technology Development (MTD),
DLV2000 is equipped to support advanced deepwater pipelay operations that will
allow pipelines to be installed at depths of up to 10,000 feet. An economical
vessel transit speed is expected to be 12 knots with a top speed of 14 knots.
On completion, the vessel will be able to accommodate up to 400 personnel.

DLV2000 is the second new-build vessel currently under construction for the
McDermott fleet. In August this year, McDermott signed a contract to build Lay
Vessel 108, sister ship to the recently completed subsea construction vessel
the Lay Vessel North Ocean 105, a vessel with a high-capacity tower for rigid
and flexible pipelay and state-of-the-art marine construction equipment to
support the growing rigid reel lay and flexible lay markets.
