Experimenting with maritime vibration and noise issues during training course

Limiting the nuisance caused by noise and vibrations on vessels is a key challenge in maritime design and engineering. Excessive vibrations can lead to equipment damage and crew fatigue. Noise is a nuisance for everyone on board, which is why clients in many projects place such high demands on sound levels. To meet the strict requirements, designers and engineers must be able to assess specialist advice and incorporate it into the design.

You can now experience the theory in practice by following the completely overhauled Onboard Noise and Vibration training on 18 and 19 June. This will give you the skills required to converse with specialists in these areas. The training course has been developed by Netherlands Maritime Technology (NMT), TNO and MARIN. A prominent new feature is tests on a pontoon on the Delftse Schie.

“The best way to describe NMT’s new Onboard Noise & Vibration training course is that it gives a solid introduction to the field without ever becoming boring,” explains Lex Vredeveldt, Senior Scientist Naval Architect at TNO’s Structural Dynamics research group. “When we’re doing a project together onboard a vessel and working with sensors, excitation devices and sound sources, participants actually becomes really enthusiastic. If you know what you’re doing in terms of physics, it’s easier to find the patience to get to know the relevant calculation methods, measurement methods and experimental techniques.”

“We have hired a pontoon on which we can place a small cabin,” Vredeveldt continues. “During the training course, we cause the pontoon to vibrate with an exciter and place sound sources on it. We then show how you can measure the response and what you can do to improve the situation. During the training, we will also make calculations related to the setup and solutions.”

Where to start with a vibration or sound issue?

Designers, superintendents, surveyors, inspectors, suppliers and consultants who deal with vibration and sound topics can all benefit greatly from this course. “After the training you’ll know where to start when confronted with a vibration or sound issue. Moreover, you’ll know who to mobilise and what to put in place to get on top of the problem. Suppose you’re called to fix a heavily vibrating bridge deck: for starters, you’ll know what to do in order to find out whether the issue is caused by resonance and what the source is. You’ll also quickly have potential solutions in mind.”
