! Essential to preserve the environment in a sensitive ecosystem
! Extreme weather conditions: Sea Ice and Icebergs Icing Polar night Low temperatures Permafrost area
! Winterization (snow, icing, wind…) Construction, Installation & process integrity Personnel protection
! Remoteness - Transportation of personnel and equipment
! Emergency Evacuation and Rescue Different environments: wave and ice Offshore: floating platform too far from shore for evacuation by
helicopter, Onshore: ice road vs helicopter but seasonal restrictions…

Conclusions
! Extreme cold areas present a huge potential with reserves
! Protected areas with sensitive ecosystems
! No universal techniques & solutions but adaptation to local context
! Need of expertise acquisition and strong partnership
