Icebergs Management at Shtokman location
! Icebergs in open water and embedded in Sea Ice, can come from Franz Joseph Land and Novaya Zemlya glaciers
! 220 icebergs observed around Shtokman area over 48 years
! In 2003, more than 15 icebergs have been observed close to Shtokman, 2 of them weighting more than 3 millions tons.
! Collision with FPU ones in 110 years, if not managed

Snøhvit
13 - SCR/ED/TA-AAH 14.04.2010
! 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…

TOTAL approach to technical challenges
! Health & Safety Ongoing innovative R&D program on winterization of workplace modules, Development of knowledges to protect/facilitate work Design of logistics rules adapted to each area of concern EER issue
! Engineering & technology Development of new materials and/or technologies from other industries Adequate monitoring technologies Gap analysis of existing technology vs needs
! Environment: Adaptation of techniques for a Zero harmful discharge policy Prevention, early detection & remediation of oil spill (under ice, thaw/frost…)
17 - SCR/ED/TA-AAH 14.04.2010
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
