Ayatsil is a heavy crude oil field located 50 miles (80.4km) northwest of Ciudad del Carmen in the Bay of Campeche offshore Mexico. It is located in water depths ranging from 114m to 121m.

Under the contract, signed with Pemex Exploración y Producción, McDermott will be responsible for design and detailed engineering, procurement, construction and installation of two subsea pipelines.

The two subsea pipelines include a 24in diameter first line (L1) and an 8in second line (L10).

The L1 is a 1.9 miles (3km) length natural gas pipeline that will connect the PP-Ayatsil-C and PP-Ayatsil-A platforms while the L10 is a 0.9 mile oil pipeline that will connect the PP-Ayatsil-C platform.

McDermott North, Central, and South America senior vice-president Richard Heo said: “This award follows on the proven track record we have had in Mexico with PEMEX – including the fabrication and installation of the Ayatsil-C platform and the fabrication and future installation of Abkatun.

“This opportunity enables us to demonstrate our subsea capabilities in offshore Mexico. We look forward to working closely with PEMEX to successfully delivering this project with safety and quality at the forefront throughout the execution.”

McDermott plans to handle project management and engineering operations through its operating centre in Mexico City.

The company expects to complete the subsea pipeline and flowline installation early next year.

The contract is part of Pemex’s effort to increase production, particularly heavy crude oil from the field.

Earlier this year, McDermott was selected by Anadarko Petroleum for subsea umbilical and flowline installation in support of a tieback to Anadarko-operated Lucius field in the US Gulf of Mexico.

Under the contract, McDermott will provide engineering, fabrication, installation and pre-commissioning of subsea infield flowlines, production umbilicals and related subsea equipment for the field.

The scope of the contract includes installation of rigid flowlines, pipeline end terminations, manifold and subsea distribution unit, umbilicals, subsea umbilical termination assembly, rigid jumpers and flying leads for the field.
