McDermott International, Inc. (“McDermott”) announced that it has been awarded a contract to install the offshore jacket, deck and piles for the Ayatsil-A drilling platform for PEMEX Exploracion y Produccion (“PEMEX”) in the Bay of Campeche Ayatsil field. The value of the award is included in McDermott’s fourth quarter backlog.

“The Ayatsil-A installation award from PEMEX is a direct result of the substantial local capabilities and operations of McDermott in Mexico, and our demonstrated track record of safe and reliable platform installations for PEMEX in the Bay of Campeche,” said Dominic Savarino, Vice President and General Manager, Americas. “Our unique ability to mobilize our versatile marine resources including the heavy-lift vessel, Derrick Barge 50, capable of lifting surface loads up to 4,400 tons, and the Intermac 600 transportation and launch barge was a critical component of the successful award for this fast-track installation project.”

The Intermac 600 will launch the 8,400-ton jacket and the heavy-lift Derrick Barge 50 will complete the installation of the jacket, a 3,400-ton deck and other platform components in waters 400 feet deep. The total weight of the facility is approximately 15,800 tons.

The Ayatsil field is the largest discovery for PEMEX to date and is expected to boost production for the country by 150,000 barrels of oil per day. This contract award follows the successful delivery of the Ayatsil-B eight-leg jacket and deck by McDermott in July of 2014.
