Stad Ship Tunnel

Stad Ship Tunnel will be 1.7 kilometres long, 37 metres high and 26.5 metres wide, and it will be able to allow ships the size of Coastal Steamer (Hurtigruten) ships to navigate more safely through the very exposed Stadhavet Sea. NOK 1 billion has been earmarked for the project in the second half of the planning period for NTP 2014-2023, and the project will potentially start after 2018.

  • The Stadhavet Sea is the most exposed, most dangerous area along the coast of Norway. The aim of this project is to allow ships to navigate more safely through Stad.
  • The Storting – Norwegian Parliament – has earmarked NOK 1 billion for this project in the final period of the National Transport Plan 2014-2023.


  • The project is now in a feasibility study phase. When the feasibility study is completed in 2017, it will undergo external quality assurance, phase 2.

  • Quality assurance has been carried out (KS1 report) which was commissioned by the Ministry of Fisheries and the Ministry of Finance for KPU 2010.

  • In NTP 2014-2023, the government has stated that they wish to proceed with a pilot project for KS2, working on the basis of the "large" tunnel alternative. This is considered to have greater potential utility value.

  • Socioeconomic analyses indicate that the net benefit will be minus NOK 910 million, while the total project costs will amount to approximately NOK 2 billion.


  • Conventional blasting is envisaged using underground drilling rigs and pallet rigs.
  • Work on alternative solutions, including the establishment of a new commercial area, is taking place locally.
  • If the project is realized, the Stad Ship Tunnel would be the world's first full-scale ship tunnel of this size.


  • Length: 1700 metres.
  • Height between ground and ceiling: 49 metres.
  • Width between tunnel walls: 36 metres.
  • Cross-sectional area: 1625 m2.
  • Volume of solid rock to be removed: Approx. 3 million m3. Equivalent to approximately 7.5 million tonnes of blasted rock.
  • Total costs: Approx. NOK 2,3 billion.
  • Construction time: Approx. 3-4 years.
