Shell awards McDermott construction work on Gulf of Mexico platform

By Phaedra Friend Troy

Shell (NYSE:RDS-A) (NYSE:RDS-B) has awarded a subsidiary of McDermott International (NYSE:MDR) the contract to construct the West Delta 143 C deck, jacket, piles and bridge destined for the US Gulf of Mexico.

Part of the Mars B development, the West Delta 143 C platform will be installed in waters measuring 370 feet deep.

Located about 130 miles south of New Orleans, Louisiana, Mars B is the second production hub on Shell's Mars field. The Mars B development will add the Olympus TLP to enhance recovery from the Mars field, as well as produce the deepwater discoveries at West Boreas and South Deimos. 

McDermott's engineering group in New Orleans will provide the detailed construction engineering and load-out analysis for the 10,120-ton platform, while the company's Morgan City fabrication facility will perform construction engineering, procurement, fabrication and onshore mechanical completion of the deck. McDermott will also help with commissioning of the platform.

First steel is scheduled to be cut later in 2011, and the platform is expected to sail away in the first quarter of 2013.

Discovered in 1989, the Mars field was first developed by the Mars A TLP. The second tension leg platform, Olympus TLP will have a production capacity of 100,000 barrels of oil a day and extend the production life of the field.

To be located in Mississippi Canyon Block 807 in waters measuring 3,000 feet deep, the Olympus TLP will be connected to the West Delta 143 C platform via export pipeline. The Mars B development will produce oil from eight Mississippi Canyon blocks, including MC 762, MC 763, MC 764, MC 806, MC 807, MC 850 and MC 851.

McDermott has build a number of Shell offshore facilities at its Morgan City fabrication yard, including the Auger, Mars, Ram-Powell, Ursa and Brutus TLP decks, and the first Shell West Delta B platform.
