Editorial: Development of advanced methods for offshore integrated wind-wave power generation devices

The huge amount of offshore renewable energy resources in deep waters has attracted tremendous interest worldwide. Different technologies have reached distinct Technology Readiness Levels (TRL), so far, confirming the intensive research, but also, the industrialization. Floating wind turbine technology has been regarded as an attractive and reliable solution for deep water areas, although it inherently has a number of technological challenges, such as the high cost and severe operational conditions. Already, floating wind turbines farms are in operation successfully without large downtimes and significant problems affecting their operation.
