Big Bubble Curtain, Oil Booms, Floating Baffles
Everything for water engineering from HYDROTECHNIK LÜBECK.
Environmental protection and technical progress from a single source. HYDROTECHNIK LÜBECK are water engineering specialists who combine environmental protection with technical progress. Along with oil booms, compressed air barriers, ice prevention systems and the creation of complete protection systems for desalination plants, underwater noise insulation is our most important
field of activity. It was for this purpose that we developed the Big Bubble Curtain — a versatile compressed air system for reducing noise emissions during offshore pile-driving, but also for protecting marine wildlife during blasting to remove munitions. For these operations, the Bitunamel Feldmann fitted out its ship the Noortruck with special hose winches and a series
of high-performance compressors. The Ocean Eagle has now also been equipped with the Big Bubble Curtain and is in operation on another construction site in the North Sea. An additional system is on standby for spontaneous operations in for example blasting.
Big Bubble Curtain
Underwater noise reduction with a flexible system.
Offshore pile driving involves an enormous level of noise pollution and thus represents a major danger for almost all marine life. The unnatural ambient noise is especially harmful for the sensitive hearing of porpoises native to the North and Baltic Seas. According to Ingo Ludwichowski from the nature organisation NABU Schleswig-Holstein, this has disastrous, mostly fatal consequences for the mammals. When the Big Bubble Curtain is deployed, compressed air hoses are laid on the seabed around the site. Powerful compressors aboard the Noortruck then push air into the perforated hoses, creating a curtain of bubbles. This “fence” of air bubbles is an effective form of noise insulation that stops up to 90% of noise pollution, undercutting even the legal maximum of 160dB.
Most important element in oil clean-up operations.
When oil is spilled in lakes, rivers or the open sea, the top priority is to prevent the spill from spreading. There are various different systems that can be used efficiently according to circumstances. HYDROTECHNIK LÜBECK has solutions for every situation or can tailor-make oil booms as required.
- Floating Baffle
A floating baffle in a reservoir or other artificial storage facility retains mechanically everything floating on the surface of the water. This could be flotsam or maybe liquids. Thanks to its special technology, the baffle adapts constantly to match the water level.
- Compressed-air Oil Barrier
Using rising air bubbles, a horizontal current in two directions is created on the surface. Floating oil or flotsam cannot cross this barrier. As a form of permanent protection, the compressed air oil barrier can be installed at desalination plants and oil terminals, but also at locks and inland ports.
- Floating Oil Booms
Floating oil booms are the oldest form of oil spill response on water. They consist of a float with an apron attached. The apron holds back the oil, while the float ensures buoyancy. We manufacture oil booms for every need using state-of-the-art materials.
- Oil Skimmers
Oil booms usually reach full capacity fairly quickly. For this reason, from the very start of any oil spill response consideration must be given to removing the contained oil from the surface of the water. This is carried out using oil collection devices, or oil skimmers. For most purposes, there are two groups of devices available, weir skimmers and adhesion skimmers.
Building and Function Protection
All components for the protection of industrial plants.
In countries with little rainfall, desalination plants are often the only possibility to supply people and agriculture with fresh water. HYDROTECHNIK LÜBECK is specialized in protecting the functions and buildings of such large complexes. On the sea side, there are two main dangers: oil pollution and flotsam. For permanent protection, compressed air oil barriers are employed on the open sea and floating baffles in the inland waters. Mobile protection is offered by oil control devices like skimmers, floating oil barriers and boats for urgent oil spill response.
Cay Grunau in person
Out of conviction, I’m a civil engineer specialized in marine and inland waters construction. This was my plan from the age of 12, when I was allowed to go with my father to a construction site at the Ennepetal Reservoir in Sauerland. Nature is simply too beautiful and important for us. So we have to protect it in those places where it’s threatened. To me, there’s nothing more wonderful than to work on and under the water and to simultaneously protect a part of the animal world – except for the smiles of my wife and children.
