Abstract
Interest in wave energy as a viable renewable energy has increased greatly in the past couple of decades. To determine the potential that a certain location has to harvest wave energy, a resource assessment must be performed for that location. As wave energy converter technologies get closer to market, it is becoming necessary to undertake more detailed resource assessments to determine the optimal location for deployment as well as the design and operating sea states. This study shows the level of sophistication that must be included in the verification process within a wave resource assessment. We describe the methodology in two articles. Part 1 described a procedure for a complete statistical analysis of the fit of the model. This paper will demonstrate how investigating systematic trends in the fit of spectral values is essential for determining the precise problem areas of the model and is thus required as part of the verification processes. Lacking this detail could mean failing to notice potentially vital issues for energy extraction at the location of interest. The identification of specific problem areas will enable a well-informed consideration of the necessary next steps for improved prediction of energy extraction.
