Onboard Noise and Vibration Training to be Held in the Netherlands
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. With this in mind, the Netherlands Maritime Technology (NMT), the Netherlands Organization (TNO) and Maritime Research Institute Netherlands (MARIN) have developed Onboard Noise and Vibration training, which will be held June 18 and 19 in Delft, The Netherlands.
This course is intended for project engineers, naval architects, people involved in research and development, technical managers and instructors.
During this training participants will learn about the principles of noise and vibration and how to keep them under control. The training will be setup around two common vibration issues and two common noise issues, which will be dealt with, both theoretically and practically. Actual tests will be done during the training, including air-borne and water-borne noise isolation, vibration isolation and the tune mass damper.
The training covers four main subjects:
On-board noise control
– Basics of noise control
– The acoustic consultancy process during ship design and building
– Regulations for noise on ships
– Representative noise levels in ships
– Noise level prediction at the design stage
– Machinery noise reduction
– Air conditioning, ventilation and exhaust noise
– Noise control in engine rooms, workshops and ECR
– Noise reducing measures in accommodation areas
On-board vibration control
– Hull girder vibration
– Deckhouse vibration
– Propeller excitation
– Main engine excitation
– Vibration of local ship structures
– Flexible mounting
– Vibration measurements
– Vibration standards
Basic principles of structural dynamics related to vibration and noise.
– Noise and vibration excitation
– Mass-spring systems
– Damage typically caused by noise and vibration
– Experimental and analysis techniques
Hydrodynamic excitation forces
– Wave induced excitation forces
– Propeller-induced excitation forces
