Noise mit­i­ga­tion sys­tem:
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.
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.
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.

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

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
