One of the most difficult tasks in designing a passenger ship is to make it vibration free while keeping the hull structure very light for stability reasons. In order to accomplish this for the 23,000 GT cruise ship shown in Table 1, special attention was paid to the alighnment of structures during layout design, and analyses and experiments of vibration were carried out through every stages of design and construction. This paper describes outlines of these tasks and examinations. The major contents are: -Arrangement of anti-vibration walls -Center core structures -Vibration analysis results -Exciter test results -Full scale measurement results -Effect of phasing of main engine revolutions
