Hydraulic engineering and port construction

The adaptation of the northern section of the Dortmund-Ems Canal (DEK) is anchored in the Federal Transport Infrastructure Plan 2030 as a project with urgent requirements. On the northern section of the DEK from Bergeshövede to Papenburg, the dimensions of the ships were limited to 95 metres in length and 9.60 metres in width. For this reason, the very old existing locks between Bevergern and…

Since 1934, the Niederfinow boat lift has provided the link between Berlin and the Baltic Sea port of Szczecin between the apex of the Havel-Oder waterway and the lower section leading to the Oder. The new Niederfinow boat lift was built between the old lift and the historic lock stairs. In 2024, the project was nominated for the German Engineering Award.

Ship lifts are extraordinary and landmark…

The Lauffen barrage is located at Neckar km 125.16 and consists of a double lock on the right bank, a three-span weir and a power station.

The right-hand chamber of the lock was extended upstream and the basic repair of both chambers and the heads was carried out. Reinforcement measures were planned to ensure stability by means of horizontal and vertical back anchoring of the walls. The wall…

The Besigheim dam is located at the lower end of an approximately 0.6 km long lock canal on the Neckar and consists of a double lock on the right bank. The associated 3-field weir and the power station are located in the Altneckar at Neckar km 136.6. As the upper gate also serves as a flood gate, only an extension to Unterwasser is possible. 

The service bridge over the lower head must be…

Due to the considerable damage caused to the existing bongossi wood stem gates of the Meldorf barrage by the boring worm and fungal infestation, the gates were only allowed to be used to a limited extent until 2020. It was necessary to replace the closures while at the same time taking into account the latest requirements of DIN Stahlwasserbau. This resulted in new loads for the bearing structures…

Within the Hanover-Magdeburg-Berlin waterway link (German Unity Transport Project No. 17), the approx. 80 km long eastern section of the Mittelland Canal is being upgraded for modern and efficient inland navigation in accordance with European standards (large motor vessels up to 110 m long and pushed convoys up to 185 m long with a width of up to 11.45 m and a draught of up to 2.80 m).

The Dörverden lock system is located on the Middle Weser in the lock canal at km 2+000 and consists of a large towed train lock built in 1910 and commissioned in 1912 and an additional small lock that was commissioned in 1938. Due to the need for year-round navigability, it had to be replaced by a new construction.
