Pipelines
Pipelines McDermott to lay Pemex line McDermott International was awarded a contract by PEMEX Exploración y Producción for procurement, construction and installation of three oil and gas pipelines ranging from 8–20in in diameter, in Mexico’s Bay of Campeche. The contract is valued at more than US$50 million. “We are pleased to be working again for PEMEX in the Gulf of Mexico. Our installation solution for this project will be supported by our subsea engineering design group in Houston and fabrication work from our construction yard in Altamira, Mexico,” said Stephen M. Johnson, McDermott’s Chairman, President and Chief Executive Officer. Pipeline installation engineering is expected to begin in the second quarter of 2011, with subsequent fabrication of the risers, clamps and guards, subsea tie-in assembly and additional platform piping and structural items from Altamira. McDermott’s DB16 will perform the installation work, with completion expected by the end of the year. DB16 is outfitted with a customised Automatic Welding System that offers high weld production rates and production flexibility. The vessel and its crew are recognized for producing repeatable high-quality welds with exceptional mechanical properties. Also impressive is the vessel’s underwater block, capable of lifting large amounts of tonnage into deepwater. The field development in the Gulf of Mexico sits in approximately 170ft of water. The pipelines will run from the Kambesah Wells Recoverer Structure to the Kutz TA platform and the Ixtoc-A platform. DB16 is a dynamically positioned, shallow and deepwater combination barge with the flexibility of installing structures or S-Laying pipe up to 48in in diameter. The vessel is equipped with three 100 kip tension machines and five pipelay welding stations, an abandonment and recovery hoist for laying down pipelines in deep water. The DB16’s 200ft long deep water truss stinger with an AFrame and an underwater block enables it to lower heavy structures up to 62t into water 10 000ft deep, and lift up to 94.5t in water depths of 6000ft.
