STAVANGER, Norway– Statoil and its partners have awarded subsea pipeline and marine installation contracts for the Aasta Hansteen field in the Norwegian Sea.
Subsea 7 has been awarded contracts worth an estimated NOK 2.2 billion ($380 million) for the subsea lines and marine operations. The contract comprises the design, coating, fabrication, and installation of 19 km (12 mi) of rigid flowlines; and the coating, fabrication, and installation of four steel catenary risers (SCRs).
The scope of work also includes the engineering, procurement, installation, and commissioning (EPIC) of rigid spools and monitoring systems for the SCRs, and protection structures and anchors for the risers, flowlines, and the spar. Further work includes the transportation and installation of the mooring system for the spar buoy.
The pipeline production activity for the SCRs and pipelines will take place at Subsea 7’s spoolbase in Vigra, Norway. Project management and engineering will commence immediately at Subsea 7’s offices in Stavanger, Norway, with offshore operations commencing in 2015 and 2016.
Deep Ocean has been awarded a contract for supply and installation of the 140-km (87-mi) fiber-optic cable connecting the Aasta Hansteen field to the existing infrastructure near Norne. This is an engineering, procurement, construction, and installation contract worth an estimated NOK 165 million ($29 million).
The contracts are call-offs on framework agreements for pipelaying and subsea installations. The assignments will commence immediately, with installation seasons in 2014, 2015, and 2016. Completion is scheduled for the 4Q 2016.
TheAasta Hansteen field development represents a number of firsts on the Norwegian continental shelf (NCS) in terms of water depth and technological solutions.
Ivar Aasheim, Statoil’s head of field development on the NCS, said: “Aasta Hansteen will contribute significantly to Statoil’s equity production when the field is onstream. This field will be the first deepwater development in the Norwegian Sea and will also open for tie-in of existing and new discoveries.
"With these contract awards we will also see the first steel catenary risers and the installation of mechanically lined pipe by reeling in the Norwegian Sea."
