Doppelschleuse Fischereihafen Bremerhaven

The Doppelschleuse Fischereihafen is a lock complex with two chambers connecting the fishing port to the Weser River and regulating water levels for vessel passage. The larger chamber measures about 181 meters in length, while the smaller one is more compact to handle different sizes of ships.

The lock was built between 1921 and 1925 to meet the modern demands of harbor operations. In 2001 it underwent a major renovation that included the construction of a new and larger main chamber.

The residential building beside the lock was built in 1925 for harbor staff and reflects the design standards of that era. You can still see the organized layout and garden spaces that supported daily life for workers and their families.

The lock operates 24 hours daily and ships communicate on Channel 10 using 'Bremerhaven Schleuse Fischereihafen Lock' as the call sign. When passing through, watch for green-green-white entry signals and maintain proper speed to ensure safe transit.

The two chambers operate on the principle of different threshold depths, meaning each one is optimized for specific water level conditions. This allows more efficient passages for different ship types under varying tidal and current conditions.
