PARIS – Nexans has a Eur10-million ($11.2-million) contract to provide a power umbilical for Equinor’s latest life extension program for the Vigdis field in the Norwegian North Sea.
When Vigdis came onstream in 1997 it was forecast to deliver 200 MMbbl of oil. It has since produced twice that amount, and Equinor now assesses the recoverable resources at 455 MMboe.
The company has commissioned OneSubsea to supply an all-electric actuated multiphase subsea boosting station receiving an HP power supply from the Snorre B platform via the new Nexans umbilical.
Vigdis produces oil through the Snorre field. The boosting station will be connected to the pipeline between the subsea Vigdis field center and Snorre A, enhancing the well stream flowing to the platform.
The boosting station will also allow wellhead pressure to be reduced, further increasing production. The facility should raise Vigdis’ recovery rate from the current 45% to 54% (a further 11 MMboe).
Nexans’ umbilical, which will combine electric power, control and communications functions in a single cable cross-section, will be developed, manufactured and tested at the company’s plant in Halden.
Load-out should follow next spring ready for installation in summer 2020.
