Coastal Highway Route E39 Project Overview. January 2012
Project Briefing in Bergen 20th January 2012 Coastal Highway Route E39 Project Overview Project Manager Olav Ellevset Norwegian Public Roads Administration (NPRA) … but challenges abound The World’s Longest….. Lærdal Tunnel (24.5 km) Nordhordland Floating Bridge (floating section 1246 m) Topographic challenges require thinking «Outside the Box» E39 Kristiansand-Trondheim about 1100 km E39 Ferry Link KristiansandHirtshals in Denmark E39 connects with E45 in Aalborg, Denmark 8 Ferry Links remaining Report No. 21 to the Storting (1994-95) 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 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 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) 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 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 Travel time in hours, summary Current 20 – 21 New 12 – 13 Savings 7-9 AADT E39 Kristiansand - Trondheim Fjord Crossings Component Managed by NPRA Western Region Recent developments, floating bridges (Norway): Nordhordland Floating Bridge Opened 1994 • End anchoring only • Length of floating section: 1246 m • Cable-stayed bridge across the ship channel • Separate pontoons New technology, yet not built Planned submerged floating tunnel (SFT) across the Høgsfjord Approved as the preferred link design (1998), but not built for political reasons Høgsfjord SFT: •Length: 1400m •Fjord depth: 155m •Anchored to the seabed Recent developments, offshore structures Ekofisk tank: 70 m depth (1973) Troll platform: 303 m depth (1995) Buoyant platforms (TLP) moored at depths of more than 1500 m Halsafjorden Moldefjorden Storfjorden Nordfjorden Sognefjorden Bjørnafjorden Boknafjorden E-39 Boknafjorden (ROGFAST) World’s longest road tunnel (approx 25 km) Depth 380-400 m below sea level Two tubes (4 lanes) Detailed design ongoing that may enable start 2015 Halsafjorden Moldefjorden Storfjorden Nordfjorden Sognefjorden Bjørnafjorden Boknafjorden Side-anchoring of floating bridges (Example: Bjørnafjorden 5-600m depth) Floating part Bjørnafjorden approx 5 km Chained floating bridge accross Bjørnafjorden Aquator/Link Arkitektur, Stord Moving 2-300 m each side with tides Corridor Concepts E39 south of Bergen Halsafjorden Moldefjorden Storfjorden Nordfjorden Sognefjorden Bjørnafjorden Boknafjorden Feasibility study – how to cross the Sognefjord Lavik Oppedal E39 ”Extreme” fjord crossing: Width: approx. 3.7 km Depth: over 1250 m, sudden deep waters approx. 1500 m to rock Sheltered from ocean waves Navigation channel required for large cruise ships Objectives for the feasibility study: Determine, at the conceptual level, whether it will be technically possible to build a fixed link across the Sognefjord. Point out the most realistic solutions based on expected technological developments. Conceptual design: Suspension bridge across the Sognefjord Conceptual design: Suspension bridge across the Sognefjord Conceptual design: Cable-stayed bridges on floating foundations Conceptual design: Cable-stayed bridges on floating foundations. Anchoring of foundations. Conceptual design: Floating bridge across the Sognefjord (mid-fjord navigation channel) Conceptual design: Floating bridge across the Sognefjord (mid-fjord navigation channel) Conceptual design: Floating bridge across the Sognefjord (navigation channel close to shore) Conceptual design: Floating bridge combined with submerged floating tunnels close to shore Conceptual design: Floating bridge combined with submerged floating tunnels close to shore Conceptual design: Floating bridge combined with submerged floating tunnels close to shore Conceptual design: Submerged floating tunnel across the Sognefjord Conceptual design: Submerged floating tunnel across the Sognefjord Further work Completing the feasibility study: Document the feasibility of the various solutions emerging from the idea phase Health and safety clarifications (construction phase, road users, shipping, structural collapse, etc.) Other factors such as costs, environmental impact, etc. Consulting Groups Sognefjord Technical Feasibility Study Dr. ing.

Progressing the project will depend on enthusiastic involvement and conscious effort invested by researchers, engineers and contractors, as well as politicians.

Explore also how the energy production potential may be utilised for the approximately 15,000 existing river bridges managed by the NPRA. Potential for renewable energy in Norway* Wave Power is estimated 600 TWh/year – Potential for development 12-30 TWh/year Tidal Power is estimated 1-2 TWh/year Wind power is estimated 14000 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 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 Examples of technological solution for various renewable energy sources Examples of power plants for various renewable energy sources 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 The subproject Energy: Feasibility study will be performed by: – Rambøll – Norconsult – SP (Technical Research Institute of Sweden) Workshop in Trondheim 19th April 2012 (RERC Conference) Research topics for master students at universities (NTNU & Chalmers) PhD projects in the field at universities (NTNU & Chalmers) 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?
