Abstract

Many military and naval operations have required some kind of wave attenuating system that can be installed rapidly for the operations to be carried out smoothly and be uninstalled when the operations have finished. This has led to the need to develop a more flexible floating breakwater which can serve the purpose. Thus, modular floating breakwaters with Lego-based design have been proposed due to their rapid installation characteristic. This research study aimed to study the wave transmission characteristics of the rapidly installed modular floating breakwaters in regular waves. The two main objectives in this study were to evaluate the effects of breakwater width and draft on wave transmission characteristics of the rapidly installed modular floating breakwaters and also to compare wave attenuation performance of the rapidly installed modular floating breakwaters of different irregular configurations. This study was a physical modellingbased project which had 19 breakwater models with a total number of 171 test runs. Each model was tested against 3 different wave periods (0.8s, 1.2s and 1.6s) and 3 different stroke adjustments (40mm, 120mm and 200mm) that produced incident wave heights ranging from 1cm to 6.5cm at a constant water depth of 0.3m. The wave attenuation performance of modular floating breakwaters were evaluated and analyzed based on wave transmission coefficient, Ct value.
