Local structural vibration analysis

Not only are yards and designers feeling the heat of ever-tighter vibration requirements; owners, too, need to reduce the downtime and repair costs of their vessels to keep business moving. 

We have the extensive experience and expertise in local vibration services you need, regardless of which vessel type you have.

Our analysis covers:

• Definition of appropriate design frequencies 
• Reasonable assumptions (boundary conditions, mass application) 
• Advice regarding  the most cost-effective modification proposals

In addition to typical structural panels, we can also investigate other, more complex structures such as masts, rudders and generator set base frames.

Furthermore, we also receive continuous feedback from operations and class surveys. This provides us with valuable input, enabling us to further expand our knowledge base and continuously fine-tune our methods.
