Technip awarded pipes and subsea structures installation contract for the Shenzi field
Technip has been awarded a contract by BHP Billiton for the flowlines(1), risers(2) and subsea structures installation for the development of the Shenzi field. This field is located in the Green Canyon area of the Gulf of Mexico in 4,300 feet of water depths. 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 centers 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 Q3 and Q4 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 Q1 2008 by the Deep Blue, Technip’s deepwater pipelay vessel. The 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.
The Shenzi field is operated by BHP Billiton and owned by BHP Billiton (44%), Repsol (28%) and Hess (28%).
(1) Flowline: a flexible or rigid pipe, laid on the seabed, which allows the transportation of oil/gas production or injection of fluids. Its length can vary from a few hundred meters to several kilometers.
(2) Riser: a pipe or assembly of flexible or rigid pipes used to transfer produced fluids from the seabed to surface facilities, and transfer injection or control fluids from the surface facilities to the seabed.
With a workforce of 22,000 people, Technip ranks among the top five corporations in the field of oil, gas and petrochemical engineering, construction and services. Headquartered in Paris, the Group is listed in New York and Paris.
The Group’s main operations and engineering centers and business units are located in France, Italy, Germany, the UK, Norway, Finland, the Netherlands, the USA, Brazil, Abu-Dhabi, China, India, Malaysia and Australia.
In support of its activities, the Group manufactures flexible pipes and umbilicals, and builds offshore platforms in its manufacturing plants and fabrication yards in France, Brazil, the UK, the USA, Finland and Angola, and has a fleet of specialized vessels for pipeline installation and subsea construction.
