Stad Skipstunnel Project: The World's First Underground Tunnel for Ships

In a pioneering effort to enhance maritime safety, the Norwegian Coastal Administration is spearheading the construction of the Stad Ship Tunnel (Stad Skipstunnel), a monumental project set to redefine sea traffic around the exposed Stadlandet. This 2.2 km engineering marvel, standing 50 m tall and 36 m wide, is poised to become the world's first fully-scaled ship tunnel.

Tunneling into the Future

Led by the visionary design of Oslo-based architectural firm Snøhetta, the Stad Ship Tunnel is not just a feat of engineering but a testament to innovation in maritime infrastructure. Wire-cutting and precision blasting techniques will bring to life the ambitious tunnel design, carefully integrated into the natural landscape through sloped terraces at each end, ensuring both aesthetic harmony and structural stability.

Construction Techniques:

  • Underground drilling rigs and pallet rigs will play pivotal roles in the construction process.
  • Approximately 3 million cubic meters of rock will be excavated during the construction phase.

Unprecedented Safety Measures

Ensuring the safety of maritime traffic is paramount, and the Stad Ship Tunnel doesn't fall short on incorporating robust measures:

  • Tunnel entrances will be reinforced with concrete blocks and rubber rudders, designed to withstand the impact of a 16,000-tonne vessel moving at 5 knots (9 km/h).
  • On the western side, an existing road will be rerouted over the tunnel, facilitated by a new bridge that not only supports the road but also serves as a strategic viewpoint for observing approaching ships and boats.
  • Illuminating the tunnel's interior will be a network of LED hoses, providing visibility and enhancing navigational safety.

Battling the Elements at Stadhavet

Stadhavet, the most weather-exposed and perilous stretch of sea along the Norwegian coast, presents challenges with unpredictable waves and strong winds, often leading to critical situations for passing ships. The Stad Ship Tunnel is not merely a construction project; it's a solution to mitigate risks and improve accessibility for sea transport. By doing so, it ensures the safety of both guests and crew on board ships navigating this challenging maritime terrain.

A Sea Change in Maritime Safety

As the Stad Ship Tunnel takes shape, it symbolizes a transformative leap in maritime safety and infrastructure. This groundbreaking project will not only redefine the seascape around Stadlandet but also set a precedent for future innovations in global maritime transportation. With its completion, the Stad Ship Tunnel will stand as a testament to Norway's commitment to advancing maritime safety standards, marking a new era in navigating the world's oceans.
