TSCHALL

Project name:

Low-frequency sound radiation of machine noises into the water Tieffrequente Schallabstrahlung von Maschinengeräuschen ins Wasser

Project partners:

DW-ShipConsult GmbH, Nobiskrug GmbH, MAN Energy Solutions SE, MV Werften Wismar GmbH, TU Hamburg

Project members:

Gyde Andresen-Paulsen, Franz von Bock und Polach, Sören Ehlers

Funding Party:

Federal Ministry for economic affairs and energy

Duration: 01.07.2018 – 30.06.2021

Project Outline:

The aim of the project is to investigate the fundamental law of low-frequency sound-excitation, -propagation and -radiation from the ship hull into the water and implementing these in a prognosis model. The model should provide relevant information in an early design stage of the ship to reduce time-consuming changes and adaptions in later project phases. The gained knowledge allows noise reduced operations and a higher acoustic quality can be guaranteed. Prospectively followed requirements concerning radiated underwater sound can be met more easily as well.
