“…The validated WEC-Sim models were then used to simulate and predict the power performance and system loads for each of the four design variations to guide OPT's PowerBuoy development. In addition, Colombia Power Technologies (CPTs) partnered with Oregon State University to develop a WEC-Sim model of CPTs 1:7 scale SeaRay WEC [25]. WEC-Sim results were compared against the SeaRay open ocean experimental data.…”

WEC-Sim (Wave Energy Converter Simulator) is an open-source code for simulating wave energy converters, which has been actively developed and applied to simulate a wide variety of device archetypes, and has become a popular tool since its release. This paper reviewed the development efforts and the usage of WEC-Sim. The publications considered in this study have been broken down into six topic areas, namely feature development, experimental validation, device modeling, control modeling, PTO and grid modeling, and novel applications, which even includes some non-wave energy applications. This review paper has also attempted to recognize the contributions of the broader WEC-Sim development effort, meaning not only the internal WEC-Sim development team but also the external efforts from the academia researchers and technology developers around the world. The growing trend of external applications of WEC-Sim has demonstrated the broader acceptance of the open-source code, and how WEC-Sim has been used in a certain topic area also highlights the potential future development needs.

“…show an example of a morphological matrix for the mechanical to electrical power train in their publication on PTO-Sim, a library for WEC-Sim which models different PTO elements [68]. In a morphological matrix, each row is a subfunction, and each cell in that row is a different concept for carrying out the subfunction.…”

“…Researchers have created Reference Models of WEC archetypes [23,97,98] that can be used as a starting point for numerical modeling. Generic numerical models of PTO subsystem components have also been created [68] as well as techniques for generic representations of control forces [76]. Designers may also use mathematical representations of moorings to approximate a mooring force on the device prior to integrating mooring models [99].…”

Wave energy is among the many renewable energy technologies being researched and developed to address the increasing demand for low-emissions energy. The unique design challenges for wave energy converter design—integrating complex and uncertain technological, economic, and ecological systems, overcoming the structural challenges of ocean deployment, and dealing with complex system dynamics—have lead to a disjointed progression of research and development. There is no common design practice across the wave energy industry and there is no published synthesis of the practices that are used by developers. In this paper, we summarize the methods being employed in WEC design as well as promising methods that have yet to be applied. We contextualize these methods within an overarching design process. We present results from a survey of WEC developers to identify methods that are common in industry. From the review and survey results, we conclude that the most common methods of WEC design are iterative methods in which design parameters are defined, evaluated, and then changed based on evaluation results. This leaves a significant space for improvement of methods that help designers make better-informed decisions prior to sophisticated evaluation, and methods of using the evaluation results to make better design decisions during iteration. Despite the popularity of optimization methods in academic research, they are less common in industry development. We end this paper with a summary of the areas of WEC design in which the testing and development of new methods is necessary, and where more research is required to fully understand the influence of design decisions on WEC performance.
