This work presents preliminary numerical simulation results on wave interaction with a fixed Bottom-Detached Breakwater (BDB). The purpose of developing fixed BDB is to provide a safe offshore zone for human activities, such as energy production and docking of large vessels, even in extreme weather. The transmission coefficient (kt) is used to assess the protection performance of the BDB. A two-dimensional Numerical Wave Flume (NWF) was developed by using ANSYS Fluent, validated with existing data and then used for studying the interaction between extreme waves and the BDB. The role of BDB design parameters such as its width and draft, and wave height and wavelength on kt was investigated. The reliability of the results of kt was verified by previous experimental study. This study demonstrates the development of a reliable NWF for conducting parametric analysis of BDBs and is a kick-off study for further developing the numerical and experimental study of floating breakwaters.
