Fatigue Assessment for Gearbox of a Floating Offshore Wind Turbine (FOWT)
Volume 1: Offshore Technology; Structures, Safety and Reliability; Materials TechnologyAbstract Due to severe working conditions, the gearbox of a floating offshore wind turbine (FOWT) is prone to fatigue damage. Fatigue failure of the gearbox may lead to significant economic losses and even potential safety incidents. Therefore, fatigue assessment for the gearbox of a NERL Spar type 5MW FOWT is performed in this paper ...

In the present study, a numerical simulation tool has been developed for the rotor-floater-tether fully-coupled dynamic analysis of FOWTs in time domain including aero-blade-tower dynamics and control, mooring dynamics, and platform motions. In particular, the effects of second-order sum–frequency wave excitations on the coupled dynamic analysis are ...

Structural health monitoring for TLP-FOWT (floating offshore wind turbine) tendon using sensors
Applied Ocean Research, 2021Abstracts In this paper, a new algorithm for the real-time structural health monitoring of TLP (tension-leg platform) tendons is presented. The algorithm is based on bi-axial sensors installed along the tendon and top tension-meter. Then, the tension and bending moment along the line can be estimated by using the developed algorithm.

This paper proposes a semi-analytical MacCamy–Fuchs–Morison (MFM) hybrid hydrodynamic model for very efficient simulations of FOWT responses without resorting to potential flow solvers. First, closed-form expressions of the 6-by-6 added mass matrix and 6-dimensional complex wave load transfer function are derived based on the Morison equation ...

Design of Floating Offshore Wind Turbine (FOWT) “SelfAligner”
2020The CRUSE Offshore GmbH has invented an innovative floating structure foundation for offshore wind turbines by using the forces of nature. The structure is a semi-submersible, self-aligning platform. The foundation is moored at a single point and uses a turret buoy to rotate freely around its anchor point.
