Revolution on the Elbe: excavator without a cargo area for the environment and efficiency!

Blankenese, Deutschland - Shipping on the Elbe is facing a possible turning point. Political support for the “System Change” project in the excavator is growing and could fundamentally change the way in which the federal waterways are maintained. Engineer Jürgen Grzeskowiak has developed an idea that relies on the excavation without cargo space and transport ships. The purpose of this approach is not only efficiency and productivity, but also significant savings for taxpayers, especially on long routes. This initiative also attracts state support, especially by Christoph Frauenpreiß and Christoph Ploß from the CDU.

In fact, the system change promises more environmentally friendly drives for the ships, while at the same time there is the possibility to equip transport ships for oil control and container intake in an accident. The Rönner Group from Bremerhaven accompanies the project and innovative technology is even protected as a utility pattern. The big goal is to clear the necessary planning agents for a pilot project in the Federal Budget 2026. However, there are also concerns: The Hamburg port administration (HPA) is skeptical and initially blocks the use of excavators without a load due to concerns about sediment management.

challenges in sediment management

The HPA criticizes the current circulatory excavator, which is ecologically questionable. Sediments are currently being deposited in front of the port of Hamburg, which leads to a variety of ecological disadvantages. In addition, polluted sediments have already been spent in the past with the approval of the state of Schleswig-Holstein. In order to free itself from this practical necessity, the HPA has now submitted an application for the transfer of excavator goods to the exclusive economic zone (AWZ) of the North Sea at the Federal Office for Sea shipping and hydrography. This step is intended to reduce the adverse effects of circulatory excavations.

The application includes impressive 1800 pages and is based on an extensive expert opinion that illuminates the water law, ecological and economic aspects. It is important that no significant adverse effects on the environment are to be expected, which was documented by a detailed expertise forecast. The BSH will now examine the application, and a multi-year process of participating relevant specialist and interest groups is imminent. But when a final decision will be made remains unclear.

a good hand for the future

In order to promote Hamburg port development, the HPA has been responsible for future -oriented port management since 2005. However, the path from the current state to implement the measures will not be so easy. HPA's skepticism compared to innovative solutions must first be broken down, and those responsible require transparent cost comparisons. Until then, some bureaucratic hurdles have to be overcome by the fact that it can be thought of by its own operation.

The question remains whether Hamburg gains the necessary confidence in innovative excavation technology, which may not only offer economic advantages, but could also make a real contribution to a more environmentally friendly company. Stay on it, because there is definitely a lot here - even if the wind just does not go in the desired direction.
