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 following completion of 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 and 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 effort as possible. That’s why we have developed a solution involving a hose that is flexible and that works without any complicated anchoring using 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. “We are therefore facilitating handling for installation companies. At the same time, we are contributing to the expansion of regenerative energy sources, thereby protecting marine life from construction noise,” adds Hoffmann.
Note: An increase in sound level of 6 dB is perceived as a doubling of the volume. Likewise, a measure that reduces the volume by 6 decibels halves the perceived noise, which is why a noise reduction of 18 dB can be quantified as a 95% decrease.
