Oslo-listed Subsea 7 has scooped two more contracts from its alliance partner Aker BP in the Norwegian North Sea.

The deals relate to the Skogul and Valhall Flank West projects and are worth between $50m and $150m.

The Skogul contract involves a tie-back to the Alvheim FPSO, starting in 2019.

The other job calls for a 4km tie-back starting next year.
