The Fehmarnbelt project will be a digital pioneer

Denmark's largest infrastructure project and the world's longest immersed tunnel. The Fehmarnbelt tunnel is a groundbreaking project in several areas. Now also as a digital pioneer. Behind the large amount of concrete and steel lies an outstanding digital project with a focus on e􀆯icient management and open use of data and information in all phases of the project.

Live from Puttgarden

A new webcam has gone live at Puttgarden, which broadcasts a livestream from the German construction site. The webcam slowly rotates across the construction site at Puttgarden, so you can follow the ongoing work in the portal area and the construction of the bridges on land. The webcam is an addition to the two existing webcams that live stream from the construction site in Rødbyhavn.

Video: How the tunnel elements are connected

When the elements have to be lowered to the seabed, it is the culmination of several weeks of preparation. A standard element weighs 73,500 tonnes and is 217 meters long. Therefore, the immersion requires a specially built vessel that can place the element with a few millimeters of precision on the seabed. This animation shows how the tunnel's elements are connected on the seabed.

Winter on the construction site in Puttgarden

It’s winter, but work continues on the Fehmarnbelt tunnel. On the German side at Puttgarden, the entrance to the tunnel – the tunnel portal - is being constructed on land 12 metres below sea level. And the work harbour receives vessels on a weekly basis bringing materials for the construction of the railway and new bridges for the local roads in the area. We have made a short video that gives an insight into the many activities this winter at Puttgarden.

Happy Holidays - 2024 will be even more busy

It has been an eventful 2023 with many highlights on the Fehmarnbelt project – casting the first tunnel element, planting the climate forest, casting the first tunnel segments in the portal areas on both sides of the Fehmarnbelt and many other milestones both on land and at sea. To mark the past year – and look a bit ahead in the new year – we have made a short video, where you can meet Anders, Holger, and Emilie from our project team, who talk about the highlights of 2023 and what awaits in 2024.

VIDEO: 5 safety tips for habour dike work

As the client, it is important to Femern A/S that safety on the construction site is top notch. That is why we have ongoing campaigns to make the workers on the entire site aware of various measures in their daily work. This month we are focusing on safety on the harbor dikes. We communicate directly on to the construction site through our info screens, so we are sure that everybody on site knows the various safety rules.

VIDEO: First time moving the floating gate

The basins in front of the tunnel factory can be closed at both ends with gates, so that the water level can be raised above sea level when an element has to be sailed out. We were there when the colossal floating gate was moved into place for the first time in the opening to the harbour.

VIDEO: Filling the basins with water

It took us 10 days to fill the three basins at the tunnel factory with 16 million cubic meters of water - the same as 640 Olympic swimming pools. We have made a video that shortens the extensive work down to 1 minute...
