Ítem Restringido Monitorización de embarcaciones y ensayos de modelos a escala(AINE, 2020-12-14) Molinelli Fernández, E.; Soriano Gómez, C.; Carrillo Hontoria, Eloy; Castaño Martínez, PedroÍtem Acceso Abierto Optimización de carenas de buques con operatividad multifunción(Asociación de Ingenieros Navales y Oceánicos de España, 2022-10-21) Molinelli Fernández, E.; Soriano Gómez, C.; Carrillo Hontoria, Eloy; Pamies Durá, J.; Senent Gómez, F."In last years, the design and operational requirements of ships are increasing significantly to meet the specifications and requirements of the shipowners. This makes ships more innovative and with less conventional characteristics to achieve better operability, having to achieve high standards in each of the operations to which they are going to be destined for not complying with the basis of its design. These atypical vessels of multifunctional design make that the semi-empirical and statistical methods used up to now offer results with more uncertainty than expected compared with the results obtained through experimental tests, since they would not be within the ranges of all the dimensionless relationships available in the databases that compose these methods. In this work, we present a recent case in which a large discrepancy is detected between the semiempirical methods and the results obtained experimentally. In this particular case, the ship, which although initially has a conventional characterization, is modified in its design with dimensionless relationships outside the operating ranges due to the introduction of multifunctionality parameters. This discrepancy forces the designer to optimize the geometry in due to the initial estimation with the semi-empirical methods because did not correspond to reality, forcing to continue iterating in the design of the geometry. An optimization is carried out in the ship geometry based on CFD analysis and the experimental results obtained and with this, a better power-speed curve is obtained, complying with the requirements imposed by the owner."
