Abstract
This MSc. thesis presents a novel developed methodology for harbor agitation analysis in real-time.
Reduced Order Models are applied for computing a sufficiently accurate generalized solution of the
linear elliptic mild-slope equation for any frequency and incoming direction given a modeled harbor.
Consequently, a highly efficient process is achieved for evaluating the solution of each incoming wave
field (any frequency and any direction) in real-time. To do this, generalized solutions are based on the
computation of a reduced basis for the given problem by using the Proper Generalized Decomposition
approach.
Once computed the reduced basis for a given harbor, the developed methodology proposes the real-
time simulation of all possible incident wave fields concerning an incident sea waves spectrum. Two
kind of analysis are proposed: the monochromatic and the multi-frequency/multi-directional one. In
the first, worst incident directions and frequencies are identiffied, while in the second a combined image
of incident waves spectrum is computed and analyzed from a functional point of view. Furthermore,
it is valuated the economic impact of the operation conditions regarding the probability of occurrence
of the simulated sea climes.
At the end of this document two illustrative examples (rectangular harbor and Port Forum harbor)
are developed by following the analysis approaches proposed in the previous chapters. As depicted
by their results, reduced order models application and the subsequent reduction of computational
time is crucial when a lot of solutions are needed. Full range evaluation of different monochromatic
incoming waves gives more precise information about harbor response and minimizes signiffcantly
the risk of disregarding possible dangerous scenarios. The computation of a unique combined image
of a single incident wave spectrum provides a realist way for evaluating real incident sea climes and
presents useful outputs for harbor exploitation and optimization.
On the whole, the developed approach provides to the harbor management engineers a practical
way to optimize and simulate the operative conditions in real harbors, increasing its exploitation
profitability and its functional design.
Descripció
Los espectros de oleaje son una herramienta básica para el cálculo realista de la agitación en. A la práctica, sin embargo, sólo se estudian una pequeña cantidad de estos oleajes porque el coste computacional asociado a todo el rango de variables de diseño resulta inabordable en puertos de tamaño medio-grande. Se propone una tesina que simule en tiempo real cualquier espectro realista. A través de una interfaz gráfica de usuario (GUI) en Matlab se evaluará el espectro para el puerto de Barcelona, posibilitándose también su implementación en dispositivos táctiles móviles.
