Resumen
Structural analysis is one of the primary concerns when designing and operating any type of marine structure. Its purpose is to ensure that the structural integrity is preserved throughout the artifact's lifespan, capable of withstanding the most unfavourable forces, and to guarantee that accumulated damage due to operational loads does not jeopardize its integrity. The objective of this work is to present the ongoing research in the field of detailed structural assessment of a vessel using a fast and reliable hydroelastic model. This model is based on the time-domain coupling of a structural model and a hydrodynamic model. To reduce the computational cost of dynamic structural simulations, the high-fidelity structural solution is projected onto the modal basis to obtain the modal matrix system and extend the Response Amplitude Operators (RAO) to the Modal Response Amplitude Operators (MRAO) of the structure. From this point, the number of structural degrees of freedom can be significantly reduced, retaining only the dominant modes that preserve most of the structural elastic energy (García-Espinosa et al. in Mar. Sci. Eng. 11:1168 [1]). This enables quick analysis of a large number of loading cases required in the design phase and implementation, for instance, a digital twin for structural health monitoring under operational conditions.
