The development of accurate design loads is a critical part of the design of a wave energy converter (WEC). In this paper, we evaluate the impact of different approaches to determining extreme wave loading on the Triton WEC using a combination of mid-fidelity and high-fidelity numerical modeling tools, complemented by scaled physical model tests. The mid-fidelity approach used is a time-domain model based on linearized potential flow hydrodynamics while the high-fidelity modeling tool is an unsteady RANS CFD model. A 1:30 scale physical model of the Triton WEC was tested at the Oregon State University Large Wave Flume. A comparison will be presented between the design loads predicted by the mid-fidelity model, the CFD model, and the physical model tests, and suggestions for best practices will be offered.
