Manobrabilidade e Controlo de Navios

Objectives

Basic knowledge in the field of manoeuvrability and control of surface displacement ships. To acquire qualificatio necessary for assessing manoeuvring qualities of ships and for selecting appropriate steering devices.

Syllabus

Introduction: dynamic qualities of surface displacement shi. Steering devices: rudders, nozzles, side thrusters. Definitive manoeuvres and their measures.Concept of a ship mathematical model. Kinematics of the manoeuvring motion. Equations of motion. Forces on a manoeuvring ship.The quasi-steadiness principle. Hull, propeller and rudder forces. Application of methods of the Computational Fluid Dynamics for prediction of hull forces. Experimental facilities. Regression models. The Munk method. Hydrodynamics of control surfaces.Mathematical models of the main engines and steering gears. State variables. Implementation of ship mathematical models in the ship handling simulators. Simulation of turning manoeuvres, spirals and zigzags: trajectories and time histories. Aerodynamic forces. Manoeuvring in wind. Eigenvalues and stability analysis.Principles and objectives of the automatic feedback control.

Prerequisites

Ship Resistance and Propulsion

Cross Competence Component

The UC allows the development of transversal competences on Critical Thinking, namely strategic thinking and problem solving approaches, within the assignemnts, flash and paper presentations, and project; Interpersonal and Intrapersonal Skills (oral, organizational and teamwork, self-discipline, perseverance, self-motivation skills - within the assignemnts, flash and paper presentations, and project); and Information and Media Literacy (ability to locate and access information, as well as to analyze and evaluate media content - within the assignemnts, flash and paper presentations, and project). The assessment percentage associated with these competences should be around 20%.

Programming And Computing Component

The students can use any platform and programming language according to their tests and preferences for developing the code required by the semester project (takes 50% of the total labour).

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.
