Technip awarded pipes and subsea structures installation for Shenzi FieldProjects and Operations // February 28, 2007
Technip has been awarded a contract by BHP Billiton for the flowlines, risers and subsea structures installation for the development of the Shenzi field.
The field is located in the Green Canyon area of the Gulf of Mexico in 4,300 feet of water. The Shenzi development requires delivery of a subsea system in water depths where Technip has extensive experience.
The contract covers the engineering, fabrication and installation of a system of two infield flowlines and six flowlines welded to steel catenary risers and connecting three drill centres to the production platform.
Pipeline end terminations (PLET) design is currently underway at Technip’s operations and engineering center in Houston (Texas) with PLET fabrication scheduled for the third and fourth quarters of 2007.
The flowlines and risers will be welded onshore, at Technip's spoolbase located in Mobile, Alabama, minimizing the duration of offshore operations.
Offshore installation will be carried out in the first quarter of 2008 by Deep Blue, Technip’s deepwater pipelay vessel.
Deep Blue will use the reel lay process, reducing the vessel’s required time in the field, thus limiting its exposure to weather and currents.
