Technical data
Project description
The 5th lock chamber essentially consists of four components:
Two lock heads: outer head, inner head
Lock chamber
Adaptation of the foreshore
The two lock heads are made of solid reinforced concrete, the walls of the lock chamber are constructed using sheet piling with a reinforced concrete superstructure and the chamber floor is installed as an anchored underwater concrete floor. The outer harbour will be adapted through extensive dredging work.

A new lock
In 2020, around 25,000 ships transported around 73.8 million tonnes of goods through the Kiel Canal, the world's busiest artificial waterway.
It has become a central artery for European freight transport. As the two large lock chambers in Brunsbüttel have been in continuous use since they were commissioned in 1914, a comprehensive refurbishment is urgently needed. After intensive preliminary investigations, the construction of a 5th lock chamber in Brunsbüttel between the existing locks was identified as the best solution from an economic and technical point of view.
