Abstract
This thesis is about evaluating isolation performance on elastomeric mounts removed from a vessel after 20-years of service. Mount properties are evaluated to determine if extending service life is feasible. Current maintenance requires elastomeric mounts of the center bonded type to be replaced on specific machinery components regardless of condition after 20-years. To determine if mounts are still effective in providing vibration isolation, several testing methods are introduced to evaluate key performance indicators needed for more understanding of life-cycle.
