2 Project History > Feasibility study of the Nord Stream Project 2005 Nord Stream AG was founded National EIA procedures and international consultations Permitting for pipeline construction Clearance of munitions from pipeline route Pipeline construction November 2011 Commencement of Pipeline 1 operation October 2012 Commencement of Pipeline 2 operation 2012 Feasibility study of the Nord Stream Extension Project Feasibility Study Pipeline design EIA Permitting and permits Munitions clearance Pipeline 1 construction Pipeline 1 commissioning Pipeline 2 construction Pipeline 2 commissioning

3 Nord Stream Extension Project > > The Project comprises the planning, construction and operation of up to two additional natural gas offshore pipelines through the Baltic Sea from Russia to Germany. > The Project will be based on the extensive knowledge and experience gained through the implementation of Nord Stream Project. > Transport capacity of each pipeline is planned to be in the order of 27.5 billion cubic metres of natural gas per year. > Pipeline design is planned to be similar to the existing Nord Stream pipelines. > The pipelines will be designed for an operating life of at least 50 years. > Total pipeline length is around 1,250 km. 3

4 Purpose and Objectives of the Project > > EU s natural gas import requirements grow continuously Natural gas is characterised by lowest emissions of the fossil fuels and is the EU s fuel of choice for substituting coal and oil. Natural gas plays a key role in the transition to renewable energy sources. EU s indigenous production is in steady decline. > New natural gas transport infrastructure is needed To enhance security of supply by offering robust, reliable and secure natural gas supplies To offer additional supply options to North West Europe 13% 30% 25% % 23% 14% 26% % 11% 16% Maakaasu Uusiutuvat Kivihiili Öljy Ydinvoima > Russia is a reliable natural gas supplier for the EU member states and has large reserves for new supplies.

6 Preliminary Project Timeline > Surveys/ Monitoring Engineering Basic and detailed design Construction support engineering EIA and Permitting EIA Phase Permitting Phase Construction Onshore Offshore Line 1 and Landfalls Offshore Line 2 Pre-commissioning & commissioning Line 1 Pre-commissioning & commissioning Line 2 6

7 International consultations under the Espoo Convention > Parties of origin: Affected parties: > National EIA procedures and international consultations are planned to be harmonised as far as possible > Parties of origin provided the Project Information Document (and the national EIA Programme) to the affected parties in the beginning April 2013 > Transboundary impact assessments will be performed within the national EIAs and collated in an Espoo report > The Espoo report will be translated into the nine languages of the Baltic Sea countries as a basis for international consultations 7

8 Technical Project > > Pipeline dimensions: Outer diameter: 1.4 m Length of individual pipes: 12 m > Preparation works: Survey and Munitions Clearance Rock Placement and Crossings Logistics: Rock Supply > Pipelay: Pipelay vessels Pipelay Logistics: Pipe Supply > Pre-commissioning, Commissioning and Operation 8

9 Preparation Activities: Surveys and Munitions Clearance > The surveys over the next 2 years include: Surveys for routing and engineering design Environmental baseline surveys Munitions screening Existing infrastructure > Where munitions cannot be avoided, clearance will be required. Options to be assessed include: In-situ detonation Relocation and detonation Relocation Recovery with onshore disposal 9

10 Preparation Activities: Rock Placement and Crossings Rock Placement > Clean rock is placed to support the pipeline > Individual berms are designed based actual seabed conditions > Precise and controlled rock placement Crossing Installation > Existing infrastructure (cables and pipelines) are surveyed > Crossings are designed > Precise and controlled installation of crossing structures prior to pipelay 10

11 Logistics: Rock Supply Potential Concept > Rock supply, potentially from existing quarries in Finland Road transport to temporary storage within the port of Kotka Loading rock placement vessels at the port of Kotka and transport to rock placement locations offshore 11

12 Pipelay: Two Types of Pipelay Vessel > Anchored pipelay vessel Positioning with 12 anchors > Dynamically positioned pipelay vessel No anchors Positioning with propellers 12

13 Pipelay > Lay rate in the order of 2 km to 3 km / day > Lay process involves: Loading of concrete coated pipes to a pipelay vessel Welding and testing of pipes on a pipelay vessel Laying of the pipeline on sea floor Survey of the pipeline on sea floor 13

14 Logistics: Pipe Supply Potential Concept > Concrete coated pipes transferred by ship to marshalling yards Marshalling yards: potentially in Kotka and Hanko > Pipes transferred by ship from marshalling yards to pipelay vessels 14

15 Precommissioning, Commissioning and Operation > Pre-commissioning includes: Flooding and cleaning of the pipeline Pressure testing Dewatering and drying > Commissioning includes: Controlled introduction of natural gas > Operation (50 year design life) 24/7 control and monitoring Regular external visual and internal inspections > Decommissioning 15
