McDermott plans to include the engineering, procurement, construction, installation (EPCI) contract in its second quarter backlog this year.
The contract, which marks the fourth for McDermott for the Ayatsil field, follows supply of Ayatsil-B drilling platform in 2014 and deployment of the Ayatsil-A offshore jacket, deck and piles earlier this year.
McDermott Americas, Europe and Africa vice-president Scott Munro said: "Our integrated EPCI approach allows McDermott to provide Pemex with a faster delivery schedule and lower-cost solution that will be locally-built and executed to our global industry-recognized quality and safety standards."
To complete the structures installation, McDermott plans to use its in-house engineering and procurement experts, the Altamira fabrication yard in Mexico, Intermac 600 transportation and launch barge and heavy-lift Derrick Barge 50 vessel.
The Ayatsil field, which is located in the Bay of Campeche, Gulf of Mexico, is claimed to be Pemex’s largest discovery to date.
The company plans to drill 43 wells on the field with four platforms and adjacent Tekel heavy oil field with one platform. These platforms will be tied to a floating production, storage, and offloading (FPSO) vessel.
