Environmental protection and technical progress from one single source

Compressed air underwater can be used in many ways

HYDROTECHNIK LÜBECK brings environmental protection and technical progress into harmony. The Big Bubble Barrier was developed for offshore noise protection in wind farm construction sites – a compressed air system that can be used flexibly to reduce noise emissions during pile driving and protect all marine life forms during ammunition clearance underwater blasting. Special nozzle hoses and hose winches have been developed for this work at sea. Experienced teams are now working around the world for environmental protection. In Germany, this development is considered to be “state of the art.” In addition to oil barriers, compressed air barriers, ice prevention systems, and the creation of complete protective systems for seawater desalination systems, underwater noise protection is our most important task.

„State Of The Art“

„State of the art“

The Big Bubble Curtain has its origins in the technology of compressed air barriers, which Hydrotechnik Lübeck has been using for more than 50 years to protect against floating debris and oil.
The Big Bubble Curtain has been used around the world since 2008 for construction work on almost all offshore wind farms and for blasting work in the North and Baltic Seas.

Industrial Building Protection

Modular system

In rain-poor countries, seawater desalination plants are often the only way to supply people and agriculture with fresh water. We have specialized in the water-side functional and building protection of these large-scale systems. There are two main dangers: oil pollution and damage from floating debris. For long-term protection, compressed air oil barriers on the open sea and floating diving walls inside are the best choices. Mobile security consists of oil rescue devices such as skimmers, floating oil barriers and boats for acute oil control.

Mission Statement

I am a civil engineer in the hydraulic engineering department by conviction. This professional goal has been clear to me since I was allowed to accompany my father in constructing the Ennepetalsperre in the Sauerland at the age of 12. The nature on our planet is just too beautiful and essential for us. So we have to protect it where it is in danger. Is there anything more excellent than being active on the water and underwater, and at the same time making your contribution to the protection of the animal world, nature, and the environment?
Except for the smiles of my wife and children. 🙂
