Nexans' solution:

  • Nexans was responsible for the design, development, production, delivery, testing and unloading of a customised static umbilical consisting of steel tubes for fluids and 1.5 kV power cables.
  • Nexans supplied umbilicals for control and chemical injection for the first seven subsea manifolds.
  • Nexans has since delivered umbilicals for associated fields such as Stær and Svale (Urd), Alve and Norne M and in 2011 for Marulk, a further branch from the Alva Field, 13.5 km away.
