STG Symposium "Selected Topics on Strength, Vibrations and Noise" 13 March 2024
Currently we see an ever-increasing importance of climate and environmental protection.
Political interest exists on the protection of the oceans from shipping borne noise. This is reflected in current activities of the International Maritime Organization, e.g., with a workshop on this topic in September 2023.
Another keyword is the European Union's Marine Strategy Framework Directive. The trend toward digitalization is continuing. We are seeing the first realizations of autonomous shipping. The product portfolio of European shipyards continues to expand its focus on special ships, in particular high-end yachts, cruise ships and naval vessels. These place the highest demands on comfort in the area of tension with high safety requirements.
For the areas of strength, vibrations and noise, this results in new challenges that need to be mastered. All those involved in shipbuilding, shipping, the supply industry and classification societies are called upon to play their part.
The STG's "Selected Topics on Strength, Vibration and Noise" day will provide information on relevant current developments with a view to the new challenges. It offers the opportunity for discussion with experts and representatives from teaching, research, industry and classification societies.
The following topics, among others, will be discussed at the Hamburg University of Technology on March 13, 2024:
Simulation techniques and measurement methods
- Condition monitoring of structures and propulsion components
- Waterborne noise predictions and measurements even in difficult environments
- Influence of propulsion components and new propulsion concepts on strength, noise and vibrations
- Vibration and noise characteristics of hull and equipment
Ship types covered include modern yachts, cruise ships and naval vessels.
