Resumen
En el presente trabajo se realiza una descripción de las estructuras offshore y de sus correspondientes clasificaciones. Se caracterizan las zonas básicas de exposición marina donde destacan la zona de salpicaduras y la de carrera de mareas por ser la de mayor riesgo de corrosión y la de mayor deterioro, respectivamente. Se valoran los mecanismos que mayor influencia tienen en la degradación del hormigón en ambiente marino, los factores desencadenantes de la corrosión del acero de refuerzo y las acciones encaminadas a reparar este tipo de estructuras. La caracterización del Delfinario Las Guasas abarca aspectos relacionados con las características generales de la instalación, materiales utilizados en su construcción, estado técnico y sistema de mantenimiento aplicado. Los resultados de la inspección realizada reflejaron que las losas de soporte ubicadas en los exteriores de la plataforma del edificio principal son las más deterioradas, por lo que ameritan de una reparación inmediata de las partes dañadas para así evitar que la corrosión conduzca a un mayor deterioro de las mismas. Se propone aplicar un sistema de mantenimiento preventivo planificado que permita contrarrestar la degradación de las losas de soporte del Delfinario y extender la vida útil de la instalación.
In the present work, a description of the offshore structures and their corresponding classifications is made. The basic areas of marine exposure are characterized, where the splash zone and the tidal race stand out, as they are the area with the highest risk of corrosion and the greatest deterioration, respectively. The mechanisms that have the greatest influence on the degradation of concrete in the marine environment, the factors that trigger the corrosion of reinforcing steel and the actions aimed at repairing this type of structure are evaluated. The characterization of the Las Guasas Dolphinarium covers aspects related to the general characteristics of the installation, materials used in its construction, technical condition and applied maintenance system. The results of the inspection showed that the support slabs located on the exterior of the platform of the main building are the most damaged, so they warrant an immediate repair of the damaged parts to prevent corrosion leading to further deterioration. from the same. It is proposed to apply a planned preventive maintenance system that counteracts the degradation of the Dolphinarium the support slabs and extend the useful life of the installation.
