Stad ship tunnel

The Norwegian Coastal Administration will build the world’s very first full-scale tunnel for ships. Stad ship tunnel will be 1,7 kilometres long (2200 metres from the tip of the lead construction to the tip at the other side) , 50 metres high and 36 metres wide, giving vessels up to the size of the coastal lines Hurtigruten and Kystruten a safe passage through Stadhavet Sea.

The Stad Ship tunnel project

Stadhavet Sea is the most exposed and treacherous stretch of water along the Norwegian coast. The goal of the project is to ensure a safer passage through Stad.

KEY FIGURES

  • Length: 1700 metres for the tunnel run. 2200 metres from the tip of the lead construction to the tip at the other side. 
  • Height from base to ceiling: 50 metres
  • Width between the walls of the tunnel: 36 metres
  • Height from sea surface to ceiling: 33 metres
  • Cross-sectional area: 1661 m²
  • Volume of rock to be removed: Approx. 3 million m³. Equal to approx. 5,4 million m³ of blasted rock – which is equal to approx. 750 000 lorry loads.
  • Estimated cost of construction: Approx. NOK 2,8 billion (2021)
  • Estimated construction time: Approx. 5 years

CONSTRUCTION

Conventional blasting, with tunnel drilling rigs and bench rigs, is planned.

Three different alternatives for the use of rock masses from the tunnel construction are being investigated, including the establishment of a new commercial area locally.

THE PROJECT

  • The Norwegian Coastal Administration devised a concept study (KVU 2010) covering the following alternatives: ‘The zero alternative’ (with no new measures), ‘Small tunnel’ and ‘Big tunnel’.
  • A quality assurance process (KS1 report) has also been carried out for KVU 2010, commissioned by the Ministry of Trade, Industry and Fisheries and the Ministry of Finance.
  • In the National Transport Plan 2014-2023, the Government said that they wanted to proceed with a preliminary project for KS2, based on the ‘Big tunnel’ alternative. This was considered to have greater potential benefits.
  • Positive effects, such as the value of moving traffic from road to sea, safety and increased tourism, as well as positive effects for the fishing industry and other industries have not been calculated.
  • Stad ship tunnel will be the world’s first full-scale ship tunnel of this size.
  • In 2017 Norconsult AS and Dr. Techn. Olav Olsen AS delivered a technical preliminary project for the ship tunnel. The report includeed the topics lead structures, entrance structures, road bridges, portals, excavation and embankment, sailing through the tunnel, roads, electrical and telecommunications installations, fire and risk, ventilation, landscape designs and the environment
  • In the National Transport Plan 2018-2029, the Stad ship tunnel was included with a cost framework of NOK 2.7 billion. NOK 1.5 billion is included in the first part of the National Transport Plan, for the period 2018 to 2023.
  • The Norwegian Coastal Administration delivered its preliminary project to the Ministry of Transport in the spring of 2017. The project has been through external quality assurance phase 2 (KS2).
  • The Norwegian Coastal Administration carried out a project optimisation, with delivery on 15 June 2019, which resulted in a significant cost reduction.
  • In 2020, an extended quality assurance process (KS2) was carried out on the results of the project optimisation.
  • In February 2021, the Norwegian Coastal Administration received the letter of commission from the Ministry of Transport, which gave the green light to start preparations for construction. In March, the Ministry presented the proposition to the Storting on construction

  • For Contractors

    The Norwegian Coastal Administration is working on the plans for the procurement of a contractor. The plan is to announce the work as a major fixed-price design and construct contract, which will be acquired after a competition with negotiation. In advance, the Norwegian Coastal Administration hos …
