Farm architecture, electrical infrastructure, operation, maintenance, mooring lines and foundations, as well as installation and logistics, represent major challenges that must be addressed before the ocean energy sector can consider the commercialisation stage. While the current conditions are acceptable for the development phase (prototype testing), they are not yet acceptable for the deployment of medium and large-scale farms. Not overlooking the design complexities brought about by the scale of the farm or not properly understand the economic and environmental impacts can have significant consequences for the overall project.
