## 5 Conclusions  
This paper offers a comprehensive introduction to the Absolute Nodal Coordinate Formulation (ANCF) theory, designed to simulate the deployment process of large floating structures in marine environments through a suspension deployment method. Utilizing the internal algorithms of the ANCF theory, this study conducts a detailed analysis of the dynamic response of cables during their release process. The effectiveness and precision of the ANCF method were corroborated through scenarios including the free-falling flexible pendulum swing and thin cantilever beams subjected to concentrated loads. In both static and dynamic analyses, across all cases, this study demonstrated that the results obtained from the ANCF model are highly consistent with the existing literature and commercial software, highlighting its capability to simulate highly nonlinear behavior.

Furthermore, this paper utilizes simulations to evaluate the proposed ANCF model under actual suspension deployment conditions, capturing the coupled effects of cables and large floating structures while considering factors such as gravity, buoyancy, and hydrodynamics. By comparing the simulation results of the ANCF method with those of the catenary method using ADAMS software under identical conditions, the study revealed the following key findings. During the lowering process, significant differences were observed in the tension-time history at the connection points between the cables and the floating structures between the ANCF method and the catenary method. This underscores the differing capabilities of the two methods in addressing unique challenges in deepwater installations, such as dynamic issues in the resonance zone, the management of hydrodynamic effects, and dynamic amplification effects. Finally, through an analysis of boundary stability in suspension deployment operations, this study examined in depth the influences of fluid velocity, floating structure weight, and total cable length on the lowering process. The research findings demonstrate the following: (1) Strong ocean currents enhance the stability of the floating structure's oscillations, thereby facilitating the precise localization of the seabed equipment's sinking point. (2) Variations in the mass of the floating structure exert limited effects on the system, with cable tension exhibiting only linear changes. (3) Changes in cable length impact the tension, displacement, and velocity of the floating structure, accompanied by a lagging response. The simulation approach employed in this study predicts the cable load capacity and trajectory of the floating structure under varied boundary conditions, offering a theoretical foundation for the next generation of deepwater deployment methods: the theory of suspension deployment. Due to the focus of this study, the construction of this model has certain deficiencies and limitations. For example, the influence of the floating structure's shape, the coupling relationship between rigid structures and flexible cables, and the stability control of the work vessel are not fully addressed. Future research will delve further into issues such as the coupled analysis of multibody systems, the interaction between flexible and rigid structures, the optimal initial state of cables, and the integration of workboats. Additionally, validating the accuracy of theoretical models via experimental testing is another promising direction.
