The SPH method is used to explore the interaction between surface waves and the vessel. The accuracy of the computational algorithm in generating incident waves has been verified through comparison with laboratory experiments. Additionally, the impact of incident waves on the motion responses of dynamically positioned mining vessels is considered by adjusting the moonpool aspect ratio. The focus is on the nonlinear characteristics induced by fluid resonance within the moonpool and the impact of higher harmonics, generated by the fundamental wave, on the vessel's motion amplitude. The findings demonstrate that the amplitude of the vessel's heave motion is positively correlated with the main frequency peak of the fluid in the moonpool.

At present, wind power development has transformed from land-based to offshore and is committed to further expanding to offshore deep-water areas.

Based on the working characteristics of large-scale FOWTs and in combination with the design experience of FOWTs, this study proposes a barge-type floating platform and mooring system suitable for a 60 m water depth to support the Technical University of Denmark (DTU) 10 MW wind turbine.

The barge-type floating platform has the advantages of having a simple structure, convenient manufacturing and a better response related to the stability (hydrostatics) of the platform under operational and extreme conditions. The hydrodynamic characteristics and coupled motion response under various wind and wave conditions of the structure were analyzed and verified by physical model tests. Key findings include the effectiveness of geometric and Froude similarity laws in model design, the critical role of low-Reynolds-number blade modifications in achieving aerodynamic thrust similarity, and the alignment of motion responses with DNV standards under extreme conditions.

The unsteady LEC detaches from the cone surface to form the Ring-like cavity, while VC initiates within shedding vortices of the sleeve. Their strong interaction causes the formation, accelerated collapse, and secondary growth of the Ring-like cavity.

Finally, momentum transfer analysis reveals that accelerated collapse results from dissipative-driven momentum intensification, and secondary growth increases momentum through reduced dissipation and vortex merging-induced low-pressure effects.

The proposed model overcomes limitations of conventional Human Reliability Analysis (HRA) by addressing uncertainty and interdependencies in performance-shaping factors. Expert evaluations of Common Performance Conditions (CPCs) were processed using fuzzy membership functions, and probabilistic relationships were modeled via a Bayesian framework constructed in GeNIe.

The findings revealed that tasks involving manual intervention and time-sensitive decisions, such as boiler uptake valve operation (HEP: 0.00234) and IG plant startup (HEP: 0.00153), have the highest error potential. Routine tasks, like pressure checks, exhibit low HEP values (e.g., 0.00040). The model was validated against Basic-CREAM for consistency.
