The major goal of this study is to experimentally investigate the characteristics of TLDs under wave excitation. An obvious engineering motivation for this study is to explore the applicability of TLD for mitigating the structural vibration of offshore platforms. The structural model used to perform experiments is scaled according to a full size platform by matching its dynamic properties. Circular and rectangular TLDs with different sizes and water depths are examined. The experiments are conducted in a 2-D wave flume. The effectiveness of TLDs is evaluated based on their response reduction. By observing the performance and the behavior of TLDs through laboratory experiments, the study investigates the influence of a number of parameters, including: container shape, container size, number of damper, incident wave characteristics, frequency ratio and mass ratio.
