PARIS – Statoil’s Snøhvit gas field in the Barents Sea offshore northern Norway will be equipped with a new static umbilical design, according to supplier Nexans. It will combine hydraulic, electrical, and fiber-optic services.
The latest phase of the Snøhvit development will establish an additional well at a new carbon dioxide (CO2) injection template as well as preparing for gas production from existing templates.
Nexans’ umbilical, to be installed in a water depth of 300 m (984 ft), will be routed between existing distribution unit to the new subsea template.
The contractor says Statoil’s umbilical design is intended to provide a consistent and cost-efficient solution for simplified or fasttrack projects, such as tie-ins to existing infrastructure, or other kinds of subsea oil and gas projects.
The umbilical for Snøhvit, manufactured in Halden, Norway, features standard elements with minor adjustments.
Snøhvit’s wells and subsea facilities are controlled directly from the onshore operations center in Hammerfest.
In 2005, Nexans also supplied the main umbilical and infield umbilicals for the original development. At 145,000 m (475,720 ft), this remains the world’s longest single-length umbilical, the contractor claims.
