5 Offshore Structures Fixed structures Floating structures Subsea arrangements (tied back to host facilities)

6 When you see this slide, what is the question? 6

7 How can we make use of this well-proven technology in the North? 7

8 Sea Ice Extent

9 Challenges in the Sub-Arctic

10 K/V Nordkapp,

11 11 /20 K/V Nordkapp Ice accretion: > Storm > T air =-15 C > 110 tons ice in 17 hrs Classical approach can not predict ice accretion on shadow areas (sides and back of the superstructure) MARICE CFD approach
