| Summary: | Load effects from breaking waves on offshore structures may be a driving point for the design. It is hence important to assess the likelihood of occurrence along the magnitude of the loadsintheeventofanimpact. Traditionally,loadsarepredicted usingwavetheorycombinedwithaloadmodelsuchastheMorison. This paper features an alternative approach in determining the loads from wave breaking. It is demonstrated how the structural response can be used for (indirectly) estimating the magnitudeoftheloadscausedbywavebreaking. Thetheoryisapplied toanexperimentalsetupinawaveflume,whereaflexiblemodel is subjected to loads from breaking waves. The dynamic propertiesaremappedusingoperationalmodalanalysisanditisconsequentlyshownthattheloadscanbeidentifiedusingthevibration measurements. |
