VIBRATION MONITORING OF NS SAVANNAH CONTAINMENT VESSEL EQUIPMENT DURING PERFORMANCE TRIALS

Items in the containment vessel which indicated resonant frequencies within the ship's operating range were monitored aboard the N.S. Savannah to ascertain whether the vibration level is within tolerable limits. A hull vibration survey was made at cruising speed (approximately 110 upm). The results indicated a sharp resonance around 64 rpm on the top of the pressurizer. Because of this resonance, the hydraulic dampers on the pressurizer were replaced by solid dampers, which reduced the overall vibration by a factor of about 1/3.
