12. LHB Date: 2005-06-07 Page: 12 Hydro Oil & Energy Ormen Lange summary: - We are on schedule and within budget!  Well defined concept at time of decision  Innovative and cost effective solutions  Focus on risk management throughout execution  Onshore experience from Sunndalsøra and Qatar  Active stakeholder management

13. LHB Date: 2005-06-07 Page: 13 Hydro Oil & Energy Shtokman – the offshore locomotive in the Arctic Mega project. Contains 3600 billion cubic meters of gas Size allows for own infra structure Shtokman is a door opener for further offshore developments in the region Shtokman can secure both US and European energy supply

14. LHB Date: 2005-06-07 Page: 14 Hydro Oil & Energy Additional Challenges on Shtokman Beyond Ormen Lange Technical Distance to shore - Flow Assurance - Control of long tie-back wells - Operational Gas Liquefaction LNG Offloading Health, Safety & Environmental (HSE) - Arctic environment Ice/Metocean - Design parameter - Ice management
