After a tender process, Kystverket, the Norwegian Coastal Administration has selected COWI as the technical advisor for the construction of the Stad Ship Tunnel. "COWI will be an important technical partner in the process of procuring and constructing the world's first ship tunnel," says project manager Terje Skjeppestad at Kystverket.

Kystverket 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 construction project itself will be carried out by a main contractor through a turnkey contract. It is scheduled to be tendered in 2024, with construction possibly commencing in 2025."

"With COWI on board, we have secured a skilled partner who will assist us with the ship tunnel. Our new technical advisor will be with us until the tunnel is fully constructed, meaning through both preparatory work and in the tendering, design, construction, and completion phases," says Terje Skjeppestad, project manager for the Stad Ship Tunnel at the Norwegian Coastal Administration.

COWI will complement the Norwegian Coastal Administration's own project team, which currently consists of 10 employees. 

"We aim to maintain a lean project organization and cannot have all expertise in-house. Through COWI, we will gain specialized expertise in various technical fields, which will complement our own professionals. Nevertheless, we anticipate that the project organization will expand significantly when we commence the actual construction of the ship tunnel, either through permanent hires, subcontracting, or utilizing the agreement with COWI," says Skjeppestad.
