“…Organic molecules, algae, anemones, bacteria, barnacles, bivalve molluscs, bryozoans, diatoms, fungi, hydroides, kelps, tubeworms-all examples of marine biofouling-can accumulate on maritime objects submerged in water [22,46,47]. This marine biofouling can cause a considerable problem for tidal turbine systems [22,48] since it can change the hydrodynamic design, increase the structural weight, increase inertia and drag load, enlarge the surface roughness, reduce the overall efficiency and power production, and contribute to structural failures [20,22,49,50]. Figure 6 depicts the marine biofouling on a tidal current turbine system.…”

A significant step in reducing the effects of greenhouse gases is obtaining electric energy from renewable sources. Electricity from tidal currents using underwater turbines is one of the most promising and well-liked technologies. The turbine systems are the key element in the tidal current energy. They are built using hydrodynamic principles to extract the most power possible from tidal ocean currents and are designed to last for extended periods in a maritime environment. The performance of tidal turbines is also significantly influenced by their materials, i.e., carbon fiber reinforced polymers (CFRP) used in them. This paper also reviews the CFRP materials used in tidal current turbine systems. Besides, an analysis of their advantages and challenges regarding CFRP materials that can impact tidal current turbine efficiency is further explored.

“…Hudson et al document the material challenges for WECs and how they impact the commonly-used materials. They discuss corrosion, fatigue, corrosion fatigue, wear/fretting fatigue, marine fouling, and impact loading and fracture and the causes, effects, and mitigation strategies for each of these challenges [148]. A report by the US Department of the Interior Minerals Management service identified applicable standards and codes for materials which included ISO 2394: 1998 (for testing of structural materials), API RP 2SM (for testing of synthetic mooring ropes), and DNV-OS-C401 (for testing of electrical equipment and cables).…”

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.
