Noise mitigation system: bubble curtain

You will receive a noise mitigation system from Jaeger Mare Solutions which is customised to your requirements. Beside the tried and tested conventional Big Bubble Curtain (BBC), we provide two new systems for reduction of naval sonars.

Underwater jobs such as laying foundations or detonations of munition can cause substantial sound emissions. Particularly the construction of offshore wind turbines causes noise which can adversely affect sea dwellers. With its Big Bubble Curtain, Jaeger Mare Solutions contributes to the protection of marine animals during rammings of the heavy offshore foundations. For the benefit of the kind-protected porpoises, differently defined noise level limit values must be adhered to. The goal of Jaeger Mare Solutions is not merely the adherence to these values but a general minimisation of sound emissions.

The Big Bubble Curtain

The Big Bubble Curtain is comprised of one or two hoses which are laid out in a ring around the source of noise. The perforated hoses are pressurised with compressed air – bubbles emerge from the seabed to the surface of the water which create a ring-shaped protective wall around the noisy construction site. With the help of the bubble curtain the sound waves extensively spreading over the seabed are broken multiple times, decreasing the sound intensity and thus protecting the marine animals. After deployment, the hose system is retrieved and brought to the next construction site.

The Jaeger BBC

With our new hose system, which is still under development, we can achieve the same noise mitigation performance with substantially less pressure. For this reason, Jaeger Mare Solutions employs a technology developed for waste water treatment which has been tried and tested for 40 years at Jaeger Umwelttechnik. With our innovative Big Bubble Curtain, we want to protect the marine animals, encourage the development of renewable energies, and reduce the costs for our customers. This is achieved with an improved bubble performance and the reduction of the required compressors.

The Jaeger CBC

Our Conducted Bubble Curtain ensures less noise in the direct vicinity of the ramming point. Jaeger Mare Solutions is currently developing a flexible Conducted Bubble Curtain which is directly attached to the steel rod rammed into the seabed and which creates a dense net of air bubbles. This reduces the noise of the over 1000 required rams directly at the source while ramming the pile into the seabed.

Korrosionsschutz: Basaltfaser-Protektoren für Offshore-Anlagen

Corrosion protection: basalt fiber protectors for offshore installations

On the lookout for a durable and ecologically harmless corrosion protection?

We provide more than that!

Jaeger Mare Solutions produces protectors made from a composition of basalt fibers which protect steel constructions in the offshore domain both from corrosion and mechanical loads. Simultaneously, the increased friction between the steel construction and the rubber fender facilitates safer climbing for technicians. Thanks to the long service life of our protectors you also decrease your maintenance costs many times over.
The boat landings of wind turbines are exposed to particularly high stresses – maintenance boats damage the surface coating of the boat landing when docking due to the up and down movement of the waves.
The Jaeger Mare Solutions protectors provide relief: the hard shells made of basalt fiber and vinyl ester resin which are attached to the fender pipes using an adhesive specially designed for this domain of application – similar to a shin guard. This may occur both onshore and offshore.
As basalt is a natural product it is also non-poisonous and thus absolutely future-proof. And this is what Jaeger protectors must be, because, even in cold and salty seawater and high UV exposure, our protectors exhibit a very long service life thanks to the basalt fabric.

Your advantages thanks to our Jaeger protectors:

  • Cost-efficient thanks to lower maintenance costs
  • Abrasion resistant: long-term protection from mechanical damages
  • UV resistant
  • Flexible installation both onshore and offshore
  • Individual choice of length and colour possible
  • Safe climbing for technicians
  • Corrosion protection
  • Shock absorbent with mechanical loads
Kolkschutz: Basaltbags

Scour protection: Basalt bags

We provide an individual protection from flushing out and undercutting at sea and in inland waters – with our Jaeger Mare Solutions basalt bags. The application possibilities of basalt bags are unlimited – let’s think outside the box together. Developed for offshore applications, the potential behind the idea is emerging stronger by the day.

Particularly the offshore wind turbines face the challenge of seabed layers around the foundation being carried off by the ocean currents. Usually, this process is counteracted by depositing stones. However, this does not always solve the challenge. Partially, the rock required for stopping the scouring process is not available in the region.

Jaeger Mare Solutions basalt bags are a flexible and ecologically friendly solution. The sacks are made from a specially developed basalt fiber and are comfortably filled with round gravel or sand on site. Beside the application as scour protection, our Jaeger basalt bags can also be used for ballasting submarine cables or pipelines and as attachment in dyke construction and coastal engineering.

Your advantages with our Jaeger basalt bags:

  • High inertia of filled sacks
  • Flexible filling of sacks on site
  • Not dependent on rock type
  • Easy installation
  • Temperature resistant from -260°C to 800°C
  • 100 % UV resistant
  • The natural fiber does not rot

Nature conservation: Porpoises

The porpoise is classified as a strictly protected species according to the German Nature Conservation Act because it considered endangered and its population is regressing.
Porpoises communicate with clicking sounds and orient themselves under water using sound. Hearing is therefore essential for the survival of the porpoise and is damaged from approximately 164 decibels. The impulsive noise as created by ramming can temporarily or permanently damage the hearing of mammals.
At Jaeger Mare Solutions GmbH we are therefore always occupied with the improvement of our sound insulation system. Since the end of 2013, the German sound insulation concept for the construction of offshore wind parks has entered force at the German North Sea. The application of bubble curtain is recommended as a noise reduction measure.
