AIDAnova

SYSTEM INTEGRATED SILENCER SOLUTION

AIDAnova the first ship of the Helios class

The highlight of the new building is the “Green Cruising” concept: AIDAnova is the world’s first cruise ship to be powered entirely by LPG. This new and lower-emission fuel significantly reduces pollutant emissions.
Expertise was needed in the development of the gas drive. With newly developed prognosis methods, Exhaust Silencers were integrated into the overall acoustic system with previously unattainable insertion losses. All competitors had previously declared the required noise abatement targets to be impracticable. We are proud that once again we were able to prove our competence.

DEEP-SEA RESEARCH VESSEL “SONNE”

SCIENCE PLACES THE HIGHEST DEMANDS

A new “sun” for the deep sea

In order to avoid as much noise as possible which could interfere with the scientific measurements, several silencers were connected in series, fine tuned on the engine frequencies,.
The 124 million euro expensive ship its predecessor of the same name which has been in operation for 35 years. The main area is to research the deep sea of the Indian and Pacific Oceans. There, scientists want to study about the effects of these oceans on climate. The ship also questions about resources from the oceans and human intervention are examined in the ecosystems.

OFFSHORE VESSELS

CONCENTRATED POWER DOWN SILENCED

Silencer for the special requirements of purpose-built offshore vessels

For a good atmosphere on board but also to please the environment. It takes a lot of experience to get the exhaust noise from the concentrated engine power under control in a very limited space.
From concept planning and prediction of the overall acoustic system to the delivery of the project-specific silencers.

POWER PLANT

IMPROVEMENT OF EXHAUST SYSTEMS

175 MW liquid fuel power plant, Viana

Analysis of acoustic conditions, planning of effective additional measures including prediction of the expected emission levels, manufacture and supply of Exhaust-gas Silencers.
After the installation of first two new silencers, an independent acoustic consulting company has issued an extensive expert opinion on the effectiveness of the new silencers. The results show that the Silencers are perfectly dimensioned and have a very significant effect with an attenuation of 10 to 25 dB at the low interference frequencies of the sound emission.
