In January 14, 2013, McDermott announced that one of its subsidiaries was awarded a turnkey contract for the commissioning of the PB-Litoral-A production platform that would be used by PEMEX E&P in the Tsimin-Xux fields off the coast of Tabasco to produce high-quality, light oil for export. With a water depth of 85 ft, PB-Litoral-A consists of a 13,838 ST platform, one flare tripod, and two bridges. In addition to commissioning, the PB-Litoral-A project scope included the start-up of an eight-legged 1,800-tonne jacket.
McDermott has the global resources and capabilities to support the EPCI entailed in this project, which were further supported by the company’s experience designing and fabricating crude oil conditioning facilities. The company carried out the front-end engineering design (FEED) with a float-over solution to install a 7,707-tonne production deck. In order to complete the project, McDermott was not shy in employing its Intermac 600 and Derrick Barge 50 heavy- duty vessels. The fist was used to install topsides with the float-over method, while the latter was used to install key platform components and provide additional support. It is worth pointing out that McDermott’s prides itself in its advanced float-over technology for heavy topsides, as it has proven to be a reliable and cost-effective method for topside installation. FEED and detailed engineering of the jacket and topsides were carried out in Chennai, India, and Dubai, UAE.
The project, which had an estimated cost of US$230 million, reaffirmed the importance of McDermott’s fabrication yard in the Altamira port in the Mexican upstream segment. The 4,500-tonne topsides, and 2,000 tonnes of tripods, bridges, and piles were manufactured in the Altamira yard. McDermott also worked on bridge and piping tie-in, as well as brownfield work on the CA-Litoral-A HP compression platform. The project engaged more than 550 craft personnel. This was the first project McDermott carried out for PEMEX, and the EPCI company also provided training to its client’s personnel for operations and maintenance.
