Why we watch it
A three-platform development now estimated at NOK 195 bn (nominal, Oct 2026): the last topsides go offshore in late 2026, with hook-up, commissioning and subsea installation running into 2027.
Phase in full, as reported
offshore installation and hook-up (Hugin B topside installed early July 2026; Munin topside loaded out at Aibel Haugesund, ready for sail-away Aug 2026; Hugin A topside sail-away scheduled December 2026; power from shore commissioned June 2026)
Reported risk in full, as reported
Cost growth: Norway's 2027 state budget (7 Oct 2026) puts Yggdrasil at NOK 195 bn nominal, up 9.8% in a year and from NOK 120.8 bn at PDO; Aker BP raised investment guidance in July 2026 to hold the 2027 start-up.
