The double lock Fischereihafen in the Bremerhaven district of Geestemünde is a lock with two chambers that connects the fishing port with the Weser .

Building history

Old lock

The double lock was built between 1921 and 1925 in order to be able to operate the fishing port behind it independently of the tides and changing water levels.

The two chambers initially had the following dimensions:

  Great Chamber Small chamber
Length: 95 m 100 m
Width of the chamber: 30 m 12 m
Passage width: 28.5 m 11 m
Dremp depth (under SKN ) : 6.32 m 6.32 m

New lock

Since the main chamber of the double lock turned out to be too small for the growing ship sizes and also restricted the shipyards in the fishing port , the Senate of the Free Hanseatic City of Bremen decided in June 1996 to build a new main chamber. After four years of construction, the new main chamber was handed over to its destination in 2001.

Today the two chambers have the following dimensions:

  Great Chamber Small chamber
Length: 181 m 106 m
Width of the chamber: 35 m 12 m
Passage width: 35 m 12 m
Dremp depth (under SKN ) : 7.95 m 5.77 m

The operations building is located next to the large chamber on the east side of the lock system. Both locks have a pumping station . In order to minimize waiting times for traffic passing through the lock during the lock process, there are lanes and footpaths on the gates on the outer as well as the inland main, which are led via bascule bridges over the upper and lower channels of the small chamber.

Housing estate

At the same time as the lock system, a small housing estate was built on both sides in 1925 for the employees of the port authorities. The ten residential units combined to form five semi-detached houses were made up of standardized components. They stood in hedge-framed kitchen gardens, facing away from the streets. Facing the streets was a small barn for chickens and pigs. A laundry room was also located in the extension. There were no car driveways or garages on the site; because the workplace was in front of the door and neighborhood help was a matter of course. To go shopping or to school, people went to Geestemünde by bike. High dikes and trees protected from the west wind, but not from the infernal noise of the riveting hammers at the nearby Seebeck shipyard . Only after the Second World War did the introduction of welding reduce noise pollution. The houses received baths and heating, but the floor plan was retained. The trees were felled in the 1960s. The lock personnel and employees of the building yard , which the Hanseatic City of Bremen Office had located on the eastern land side of the double lock, lived in the houses until the end.

Customs ship station

Next to the weather station on the western north side of the double lock was the building of Customs Border Inspectorate II built after 1945. The two patrol boats with 2000 and 800 hp were berthed on a floating dock in the Geeste outer harbor.
