“…Considerable efforts have been made to develop safe and efficient floating offshore wind turbines suitable for water depths exceeding the economic limit of fixed monopile or jacket-supported wind turbines [3,4] . Technologies applicable to such wind turbines have been developed; for example, Yang et al [5] presented a thorough summary of commissioned floating offshore wind projects and their mooring systems, showing the versatility of the currently applied concepts. International standards [2] have been developed to ensure wind turbines are designed according to sound engineering principles.…”

The wind farm owner/operator must prepare a Design Basis to facilitate the design of floating offshore wind turbines. The Design Basis is crucial to ensure that the individual elements of the wind farm are designed according to the relevant standards and the actual site conditions. In case of under-design, systematic failures can occur across the wind turbines, which can result in progressive damage to the turbines of the wind farm. This paper focuses on the safety and overall economics, including limiting potential excessive costs of heavy maintenance caused by damage due to under-design. Thus, this paper highlights critical aspects of particular importance to be implemented in the Design Basis document. Meeting all required constraints for developing offshore wind farms in deep water may result in higher costs than initially anticipated. Nonetheless, a realistic cost estimation for all phases of the project, engineering, construction, transport, and installation on site, remains essential for all engineering projects, including those involving renewable energy.

Structural health monitoring in floating offshore wind turbines’ mooring lines is vital for detecting early faults and preventing disruptions. Currently, sporadic and expensive monitoring is conducted via remote-operating vehicles. Efficient, automated, economical monitoring methods based on a continuous stream of data acquired via multiple measurement points in the wind turbine, are required. Such methods based on vibration signals have been investigated limitedly for steel chains. Recently, faulty synthetic mooring lines of a simulated 10MW semi-submersible wind turbine have been detected under varying environmental conditions and via the Functional Model Based Method (FMBM) equipped with functional models. The uncertainty due to the conditions’ stochasticity has been addressed by training the models using ten signal realizations per condition (wind) under the healthy wind turbine and from each of two measurement points. The current study presents a preliminary sensitivity analysis of the FMBM’s capability in detecting the simulated wind turbine’s faulty mooring lines when the functional models are trained using one signal realization per varying condition (wind) from each measurement point. The method’s effectiveness is evaluated with acceleration signals from 11 healthy/ 66 faulty (reduced stifness in one mooring line) cases. The FMBM detects all cases even when trained using one signal realization.
