Visit Bremerhaven in northern Germany and you will see Europe’s largest harbour job site. The transportation of containers via Bremerhaven is experiencing a boom like just about no other industry in Germany, with annual growth rates sometimes hitting double figures. In just 27 years the Weser estuary has become Europe’s fourth most important container terminal, and a leading player on the international stage.
To maintain this position in the future, owner Land Bremen is extending its container terminal from 3,200 square metres to 4,872, at a cost of some 500 million euros. In doing so, it is creating space for four additional state-of-the-art container vessels.
The contract for this massive project has been secured by CT 4 joint venture, a consortium of Hochtief Construction, Bilfinger & Berger, Strabag and Gustav W Rogge. The JV is responsible for installing 37,000 tonnes of steel sheet piles, 10,000 tonnes of reinforcement steel and 60,000 cubic metres of concrete, as well as infilling 10 million cubic metres of sand. Liebherr construction machinery is the key to its success.
The installation of a riverside sheet pile wall in the tidal Weser, using Liebherr crawler cranes plus those with specialised deep foundation equipment, represents the most important and, at the same time, the most complicated phase of this project.
