The Ayatsil field, which is the largest discovery for PEMEX to date, will strengthen production by 150,000 barrels of oil per day.
McDermott International Americas vice president and general manager Dominic Savarino said: "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.
"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 contract follows the Ayatsil-B eight-leg jacket and deck delivery by McDermott in July 2014.
