Abstract Floating offshore wind turbines (FOWT) need to maintain their position even during the most extreme events or energetic storms. The mooring and anchoring systems are the responsible to provide the station-keeping of the FOWT so, the effect of their behaviour affects directly to the dynamics of the floating platform and it has to be carefully assessed during all the design stages. Although the station-keeping of vessels and offshore structures has been carried out for centuries, FOWT represent a relatively recent field of application with specific requirements and challenges. Existing experience from the offshore oil and gas industry, as formulated in a number of design criteria and guidelines published by American Petroleum Institute (API), International Organization for Standardization (ISO) and classification societies, can be adapted for this specific application but taking into consideration the existing differences. A general overview regarding mooring and anchoring systems applied to FOWT is provided in this chapter, taking into account the most usual system configurations and their associated types of anchor, likewise materials. A range of requirements that should be considered for the design of FOWT mooring and anchoring systems is included. Finally, methods for structural analysis and the main specific mooring system guidelines are identified.
