Flood protection Protecting the population – flood protection projects at bremenports

We keep 22 kilometres of dykes and flood barriers in good working order and also look after the greenery. But that is not all we do: we are also responsible when the dykes have to be raised and fortified.

To give you an idea of the excellent work done by our experts, we have compiled a list of the current flood protection projects with brief explanations:

Construction projects at the northern and southern sea dyke in Bremerhaven:

The sea dyke in the south of Bremerhaven, to the west of Fischereihafen, runs from the double lock at Fischereihafen in the north to the former boundary to Lower Saxony in the south. The first construction phase of Offshore Terminal Bremerhaven (OTB) in autumn 2016 involves relocating part of this sea dyke. This means constructing a roughly 460-metre long section in the southern part of the sea dyke. The new dyke has to have a larger cross-section than the original structure: the outer part slopes at a lower angle, taking it approx. 12 metres closer to the River Weser. This construction phase is scheduled for completion at the end of 2017.
The northern part of the sea dyke will also be refurbished in spring 2017. During the next construction phase, the outer part of this section will also be given a gentler slope along a length of approx. 950 metres, again taking it closer to the river.

Marine debris storage and removal on the Luneplate:

To protect the hinterland, Luneplate has a dyke with a total length of 5780 metres. To keep these areas in good condition, the existing infrastructure has to be upgraded. One of the measures involves improving and extending the path for removing marine debris from the Luneplate. This measure is of central importance for coastal protection and was already included in the list of measures for implementing the Master Plan for Coastal Protection. On completion of the planning stage, a path for removing marine debris will be constructed between 2017 and 2018, with a length of approx. 760 metres in the southern area and approx. 1150 metres in the north of the Luneplate.
Correct disposal of marine debris is also crucial importance and accordingly, there are plans to construct a dedicated site for the storage and treatment of this debris on the inside of the Luneplate dyke. The construction of an approx. 25,000 m² surfaced site for the storage, treatment and composting of marine debris is scheduled to begin in 2017.
Compensation measures will have to be implemented for the construction of both the marine debris storage site and removal path. The substitute site for the debris storage site will be in the lower Lune area, whereas compensation for construction of the removal path will be at the Drepte lowlands.

Refurbishing flood protection at Columbusinsel in Bremerhaven:

Columbusinsel is situated between the Nordschleuse and Kaiserschleuse locks in the Überseehafen district of Bremerhaven. The dimensions of the present flood barriers on Columbusinsel do not satisfy the latest requirements, so that some parts have to be raised, while others have to be completely rebuilt. Structural designs have been drawn up to outline how the future flood protection on Columbusinsel is to be refurbished for the future. The application for planning permission was submitted in autumn 2016 and construction of this section of the flood barrier is scheduled to begin at the end of 2017.

Refurbishing flood protection at Nordschleuse lock in Bremerhaven:

Nordschleuse lock is situated between Columbusinsel and the Container Terminal in Bremerhaven’s Überseehafen district. The Master Plan for Coastal Protection specifies that the lock gates, the lock heads and the flood control line on both sides of the lock chamber are not high enough. These structures were therefore adjusted between 2014 and 2016 to comply with the requirements of the Master Plan for Coastal Protection. The work was completed in November 2016.

Refurbishing flood protection at Oslebshausen lock:

Oslebshausen lock marks the entrance to the Industriehafen terminals in Bremen. The Master Plan for Coastal Protection specifies that the present flood protection facilities of Oslebshausen lock (the lock gates, the lock heads and the flood protection line on both sides of the lock chamber) are not high enough. Structural designs have been drawn up to outline how the future flood protection in the lock area is to be refurbished for the future. An application for planning permission for this construction project was submitted in Q3 2016. Construction of this section of the flood barrier is scheduled to begin in 2017.
