Abstract
Anthropogenic noise pollution is one of the primary drivers that alter the ocean landscape through its impact on marine ecosystems. Submarine pipelines in particular produce a constant source of low frequency noise, which can propagate further with less energy dissipation over vast distances. This thesis focuses on analyzing the potential of a Locally Resonant Metamaterial (LRM) based on an oscillating cantilever ring design, and its reduction in the vibration response of an underwater PVC-U pipe. The dynamic behavior of the pipe is experimentally evaluated in air through impact hammer testing, alongside a COMSOL Multiphysics model to create a baseline comparison. Next this model is transferred to an underwater system, where the metamaterial design is adapted to attenuate the first underwater eigenmode. Based on these results, the metamaterial design was fabricated through SLA 3D printing methods, before conducting a final physical evaluation using a vibration generator in both air and water.
