 pan><br>Statoil is operator in field developments offshore East Coast of C
 anada and in the Norwegian Barents Sea in waters were sea ice intrudes sel
 dom (CA) or extremely rarely (NO). Both developments have in common that F
 PSOs will operate in open water but still need to consider ice loads as pa
 rt of design. Norwegian laws require that the knowledge base is included a
 s part of the risk definition. The consequence of this for Arctic Norwegia
 n projects is that uncertainties in design basis shall be compensated with
  more robust solutions in order to keep risk at the same level as in non-a
 rctic locations. Assessments done for the Johan Castberg project are prese
 nted with focus on possible consequences from using immature ice load mode
 ls. The need for including ice exposure in load assessments and to relate 
 loads to exceedance probability levels is highlighted.</span>
