HOUSTON, Sept. 25 -- Esso Norge AS has awarded a contract valued at 75 million euros to Technip-Coflexip's Norwegian unit Coflexip Stena Offshore Norge AS for engineering, procurement, construction, and installation of 81 km of rigid natural gas flow lines, flexible risers, and flexible jumpers from Ringhorne field to Jotun and Balder fields.
Ringhorne field is in Blocks 25/8, 25/10, and 25/11 in the Norwegian sector of the North Sea about 160 miles west of Haugesund in water 124-129 m deep.
Installation will be performed in cooperation with global subsea contractor Subsea 7 in a 50:50 work split.
The work includes procurement, fabrication, and installation of 33 km of 6-in.and 24 km of 8-in. and 12-in. rigid flowlines; 10-in., 8-in., and 6-in. flexible risers; and a 6-in. flexible jumper, which will be manufactured at the company's plant in Le Trait, France.
The work also includes hookup of spools using divers, diverless tie-ins, presurvey, crossing preparation, trenching, rock dumping, and commissioning of the installed system.
The facilities will be installed in summer 2003. Technip-Coflexip will use CSO Apache and Normand Pioneer pipelay vessels. Subsea 7— formed in May 2002 in a combination of the business and assets of Halliburton Subsea and the subsea business and assets of DSND Subsea ASA—will employ its Skandi Navica for rigid pipelay, the Toisa Polaris for the Ringhorne tie-ins, and the Seisranger and Kommandor 2000 for survey and construction support.
The project will be managed from Technip-Coflexip's Oslo offices with support from Subsea 7's Stavanger and Grimstad operations.
