Transcription

1 Project Briefing in Bergen 20 th January 2012 Coastal Highway Route E39 Project Overview Project Manager Olav Ellevset Norwegian Public Roads Administration (NPRA)

2 but challenges abound

3 The World s Longest.. Lærdal Tunnel (24.5 km) Nordhordland Floating Bridge (floating section 1246 m)

4 Topographic challenges require thinking «Outside the Box»

5 E39 Kristiansand-Trondheim about 1100 km E39 Ferry Link Kristiansand- Hirtshals in Denmark E39 connects with E45 in Aalborg, Denmark

6 8 Ferry Links remaining

7 Report No. 21 to the Storting ( ) Coastal Highway Kristiansand-Bergen-Trondheim Fixed links across the Boknafjord and Bjørnefjord are regarded as unrealistic in the foreseeable future A fixed link across the Sognefjord is regarded as unrealistic

8 The Ministry of Transport and Communications NPRA commissioned to: Establish the potential for trade and industry, employment and settlement patterns of a coastal highway with no ferry links Explore technological concepts for fjord crossings Assess renewable energy potential Implementation strategies and contracts

9 E39 Coastal Highway Project A knowledge project Four Components: Society Technology (Fjord Crossings) Energy Implementation Strategies and Contracts Approx 1100 km Concept approx size NOK 100 bn (Euro 13 bn)

10 The Society Component Managed by NPRA Central Region Good methods for estimating the impact on transport costs Harder to quantify the impact on national and regional economies larger areas of residence and employment long term structural changes

11 Key focuses for Society component New transport model for E39 at national and regional level Introducing new impact elements into socioeconomic analyses, like long term structural impacts of reduced travel time for Bergen-Haugesund-Stavanger (avearage wage raise) Northwestern Norway, Kristiansund-Molde-Ålesund ++ Long term changes in settlement patterns and trade and industries Searching for methods for assessing macroeconomic impacts

12 Travel time in hours, summary Current New Savings 7-9

13 AADT E39 Kristiansand - Trondheim

14 Fjord Crossings Component Managed by NPRA Western Region

41 The fjord crossing project Fjord crossings which were previously considered impossible without a ferry service now appear to be potential candidates for a fixed link in the reasonably near future. Progressing the project will depend on enthusiastic involvement and conscious effort invested by researchers, engineers and contractors, as well as politicians.

62 Energy Component Managed by Road Safety, Environment and Technology Department, NPRA Headquaters Oslo Consider how bridge infrastructures can be utilised for producing energy from the renewable sources solar, tide currents, waves and winds. Explore also how the energy production potential may be utilised for the approximately 15,000 existing river bridges managed by the NPRA.

63 Potential for renewable energy in Norway* Wave Power is estimated 600 TWh/year Potential for development TWh/year Tidal Power is estimated 1-2 TWh/year Wind power is estimated TWh/year The total energy consumption in Norway is: 228 TWh in 2008 (50% electricity) *Results from feasibility study report from ENOVA in 2007, Item No: 12502

64 La Rance Tidal Power Plant in France The world's first and also the world's second biggest tidal power Plant is a bridge Operated since 1966 Annual output 600 GWh 24x10 MW turbine 750 m long Max tide range of 13m

69 Feasibility study The main objective is to assess the energy production potential and the accessible potentials with focus on coastal highway route E39. The study is divided in two separated part: Part 1. Technology survey for renewable energy associated to tidal power as waves and currents Part 2. Technology survey for renewable energy associated to wind and sun

71 Implementation Strategies and Contracts Component Consider suitable implementation strategies and types of contracts for a project of this size Financing options? PPP options? Ranking of individual projects? Contract sizes and packaging of projects? Dedicated management company for the project? Mr. Jan Eirik Henning will go into more details

72 Some other issues Earl stage Dialogue for implementation issues Corridor and formal planning status - huge challenge Relatively low sensitivity for road tolls Conflicts of interest Patent rights Road infrastructure combined utilization

73 In the 60-ies, who could imagine that structures would be located in the middle of the North Sea? The North Sea
