Aker BP and Subsea7 Norway awarded Tenaris two contracts for the supply of casing and tubing, and line pipe respectively, for the Fenris project.
Fenris is a gas reservoir, which will be developed by an unmanned installation (UI) with 8 slots, subsea tied back 50 kilometer to the Valhall field centre in the southernmost part of the Norwegian continental shelf.
Tenaris will provide approximately 7,000 tons of pipes, ranging from 10” to 17” OD, with TenarisHydril Blue® Max and Blue® Heavy Wall premium connections and Dopeless® technology and with sour service grade, TN 125SS. The use of Dopeless® technology, a dope-free solution, offers customers operational and environmental benefits, from reduced running times, nearly zero rejects/re-make ups and enhanced safety through zero discharge.
“The project requires highly sophisticated products that have been extensively tested,” says Tenaris Country Manager in Norway, Christer Andersen. “In Norway, dope-free solutions are a standard in oil and gas operations, imposed by governmental environmental regulations. For the Fenris project, Tenaris was awarded the supply of intermediate and production casings due to the API RP 5C5 CAL IV testing of TenarisHydril Blue® connections, tested with Dopeless® technology as well as their track record in HPHT projects”, adds Andersen.
The line pipe award has been managed by Subsea7 Norway, which is responsible for the engineering, procurement, and installation of the 50 kilometer subsea tieback connecting the Fenris unmanned installation to the Valhall production and wellhead platform. Tenaris will supply approximately 10,000 tons of 14”, 12” and 4” OD line pipe, including the application of anti-corrosion coating.
