Diseño estructural y simulación dinámica de un sistema de compensación de rolido para buques.

Abstract

This project develops a methodology for dynamic analysis and structural design of a passive roll compensation system for ships using the state of the art code ANSYS-AQWA for hydrodynamic simulation and MATLAB software for stochastic fatigue structural design. The case study contemplates a 5000-ton resting ship, to which different configurations of the compensation system are coupled. This system is made up of Steel beams, reinforced concrete plates and a spring system to increase dynamic stability. Initially, a conceptual design is carried out, on which hydrodynamic simulations are run using time and frequency domain methods in ANSYSAQWA to obtain response parameters such as tensions and hydrodynamic forces, which are necessary for the operability analysis. Following this, these response parameters are used for static design in ANSYSSTRUCTURAL and fatigue in a MATLAB toolbox to optimize the geometry and materials used in the conceptual design. Finally, the performance of the optimized system is assessed for a potential marine operation for the Ecuadorian coasts.
