Hidrodinâmica de Sistemas Flutuantes

Objectives

Acquire knowledge about ocean floating systems in particular aspects related to its dynamics and interaction with mooring systems.

Syllabus

Introduction of different components of floating systems and their design formulation. Formulation of the boundary value problem for the 3D description of the motions of floaters. Linear hydrodynamics of the slender ships with speed of advance in waves. 2D and 2.5D strip theories. Linear hydrodynamic theory for 3D floating systems without forward speed, subject to wave motions. Equations of motion describing the behaviour of platforms in regular seas in the frequency and time domains. Green’s bi-dimensional and tri-dimensional functions. Perturbations Methods. Second order forces and movements. Drift forces. Low frequency drift forces. Drift caused by wind and currents. Non- linear simulation in the time domain, Dynamics of Single Point Mooring Configurations. Mooring systems: tension cables and catenaries. Design of mooring systems. Hydrodynamic damping of mooring lines.

Prerequisites

Fluid Mechanics, Dynamics and Hydrodynamics of Floating Bodies

Cross Competence Component

Communication, Listening, Presentation, public speaking, writing report, group work

Programming And Computing Component

Both project works require the extensive use of computational methods to determine the responses

Ethical Principles

All members of a group are responsible for all group's work. In any assessment every student should honestly disclose any help received or sources used. In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
