August 2023 | Fehmarn
To enable the visitors of the Meereszentrum on Fehmarn to enjoy the absolute attraction of the ocean aquarium, the sand tiger shark lady Jaqueline and various other shark species such as black tips or a nurse shark, the panorama pane of the large aquarium has to be cleaned from the inside from time to time. An unusual operation for our diving team.
In warm water, crystal clear visibility and under strict supervision of the marine center manager, the pane was cleaned in the water with the help of a plastic card and a classic pane cleaner. A metal basket, open only on the side to the window pane, protected the divers from the curiosity of the large predators during this operation. An exciting experience for the team.
6th June 2023 | Bremerhaven
On June 6th our team was ordered to a salvage operation in the Kaiserhafen in Bremerhaven. A container ship had an approx. 85 m long anchor chain including anchor in the propeller. With the help of a mooring line, the chain was lifted and cut by the diver below the propeller. The anchor chain and anchor were then salvaged by a mobile crane.

2022 | Bremen, Bremerhaven, Hamburg and Kiel
Due to intensive discussions, we were able to convince further environmental authorities / port authorities of our environmentally friendly process for propeller cleaning. In addition to the permit from Bremerhaven, which we have held since 2020, we now have temporary permits to carry out propeller polishing in the ports of Bremen, Hamburg and Kiel.
The diving works will be carried out depending on the local conditions (including visibility, current and shipping traffic). During all operations, samples of the re-injected water are analyzed by a certified laboratory. We are glad to be able to take another step towards environmental and water protection in cooperation with the local authorities.
2021 | Graal-Müritz
In cooperation with the diving company Fred Babbel, the approx. 280 m long lake outlet pipe DN1200 at the Stromgraben pumping station in Graal-Müritz, Mecklenburg-Vorpommern, was inspected with the help of our ROV (Remotely Operated Vehicle) Hyball. This small remote-controlled diving robot is equipped with a camera and therefore, it is possible to localize damages to the pipeline or blockages in the pipe.
2021 | Bremerhaven
Environmental and water protection is as important to us as the development of innovative products and solutions. This has motivated us to look into the topic of propeller cleaning.
The cleaning of propellers is not allowed in German ports, because the cleaned substances contaminate the water, e.g. also by heavy metal contents. Propellers covered with barnacles and marine fouling, however, have to be operated with more effort, which leads to a significant increase in fuel consumption. This has a greater impact on the environment than driving with a cleaned propeller. For this reason, in cooperation with Bremerhaven University of Applied Sciences, we have developed a system that filters out cleaned material when the propeller is polished and then returns the cleaned water to the harbor basin. Appropriate water samples are analyzed by a certified laboratory each time the system is used.
As far back in 2020, the Bremen environmental authority gave us preliminary approval to test this system and polish propellers in Bremerhaven's harbor basin. Now that a large number of propellers have already been polished, our system has been further optimized and important results have been obtained from the samples analyzed in the laboratory, we will expand our test areas. We are in contact with further ports and the responsible environmental authorities in order to be able to offer our system for legal and environmentally friendly propeller cleaning there as well.

Der schwimmende Bagger wird zu Wasser gelassen
An der Okertalsperre im Harz wurde am vergangenen Dienstag, 22.09.2020, ein 30-Tonnen-Bagger von der Staumauer aus zu Wasser gelassen. Der Seilbagger, der für 14 Tage auf einem Ponton auf der Okertalsperre schwimmen wird, soll Treibholz und Schwemmgut aus der Nähe der Mauer entfernen. Ziel ist es, dass nach der Säuberungsaktion Taucher an der Mauer arbeiten können. „Wir sanieren und dichten auf rund 60 Metern Länge eine Fuge ab“, erklärt Marie Kleine, Pressesprecherin der Harzwasserwerke. „Aktuell verlieren wir durch die undichte Fuge kontinuierlich einige Liter pro Sekunde aus der Talsperre. Das wollen wir in Hinblick auf die immer wieder kehrende Trockenheit ändern.“
Damit die Taucher allerdings die Fuge mit einem Geokomposit aus PVC und Textilelementen abdichten können, muss zunächst der Bagger ran. Los ging es an der Okertalsperre zunächst am Vormittag mit dem Ponton, das an der Staumauer befestigt wurde. Dann hob ein Kran den Bagger auf das Ponton. Insgesamt kostet die Bagger-Aktion und Sanierung der Fuge rund 300.000 Euro. Durch die Bauarbeiten im Wasserschutzgebiet ist bis zum Freitag, 02.10.2020, mit Einschränkungen zu rechnen.
