Subsea 7 awarded contract offshore Gulf of Mexico

Luxembourg - 21 March 2017 - Subsea 7 announced today
the award of a large(1) contract by BP as part of the
deepwater Mad Dog 2 development, located approximately
190 miles south of New Orleans.

The contract scope covers engineering, procurement,
construction and installation (EPCI) of the subsea
umbilicals, risers and flowlines (SURF) and associated
subsea architecture.

Subsea 7 has worked closely with BP to deliver a lump
sum integrated solution from design through to supply,
installation and commissioning. Furthermore, by
collaborating with OneSubsea, a Schlumberger company,
our Subsea Integration Alliance(2) partner that has been
awarded the Subsea Production Systems (SPS) contract,
additional areas of cost improvement have been identified
to provide greater cost certainty and reduced risk.
This has enabled the original cost of the Mad Dog 2
development to be substantially reduced.

Together the SURF and SPS contract awards are a
significant endorsement of our Alliance offering
and confirmation of the client's high level of
interest in this approach, and in Subsea 7 as a key
partner. This is also the first substantial project
in the US to use Subsea 7's Swagelining(3) polymer
lining technology.

Project management and engineering will take place
in Houston, Texas with support from Subsea 7's
Global Project Centre in London, UK. Offshore
installation activities are scheduled for 2019
and 2020.

Craig Broussard, Subsea 7 Vice President for the
Gulf of Mexico, said: "The Mad Dog 2 project is a
significant award for Subsea 7. It combines Subsea 7's
capability with our Subsea Integration Alliance value
offering to reduce risk and provide lower cost solutions
for BP. This project serves as a step-change of how
we work in the region and in Subsea 7's ability to
deliver superior value to the industry."
