PARIS – Murphy Exploration & Production Co. – USA has awarded Technip (Paris:TEC) a lump-sum contract to develop Dalmatian field in the Gulf of Mexico’s De Soto Canyon blocks 4, 47, 48, and 91.
Dalmatian, in water depths of 530 m to 1,800 m (1,739 ft to 4,921 ft), is jointly held by Murphy and Ecopetrol America Inc.
The project is a subsea tieback to an existing platform and covers project management, engineering, fabrication, and installation of a gas riser, an oil riser, a 38-km flowline, and a 34-km pipe-in-pipe flowline with associated PLETs and jumpers, installation of a main subsea control umbilical, infield umbilical, and associated foundation and flying leads, and pre-commissioning.
Technip in Houston will perform project management, and the flowlines and risers will be made up at the spoolbase in Mobile, Alabama.
Installation is scheduled to be complete in 2013 and will use the Deep Blue deepwater pipelay vessel, the Pioneer which came with the Global Industries acquisition, and the HOS Iron Horse multi-service vessel.
