A heavyweight for easy handling
Previously, installation companies fitted the hoses with additional weights to anchor them to the sea floor or positioned them on piping systems. However, these structures create complications when the bubble curtain is to be transported back to the surface of the water after the work or when it is to be installed on the sea floor. What makes Continental’s development special is that an additional wire is wrapped around the hose. The result is a real heavyweight that lends the hose the right degree of balance at the required depth without the need for compressed air to keep it buoyant.
“As with all construction projects, it’s all about doing the work as quickly and with as little work as possible. That’s why we have developed a solution with a hose that is flexible and works without complicated anchoring with additional weights such as steel chains,” explains David Hoffmann, who is responsible for industrial hose solutions in the EMEA and APAC regions at the Continental Corporation. “With this, we are making handling easier for installation companies. At the same time, we are making a contribution to the expansion of regenerative energy sources, thereby protecting marine life from construction noise,” adds Hoffmann.
The big bubble curtain hose for sound insulation is suitable for many other applications, such as mine clearance, offshore oil drilling, seismic surveys, port and coastal development, bridge-building and the construction of artificial islands.
Note: An increase in sound level of 6 dB is perceived as a doubling of the volume. A measure that reduces the volume by 6 decibels halves the noise accordingly which is why a noise reduction of 18 dB can also mean 95%.
