Content and learning outcomes

Course contents

The course is built around a number of assignments supported by lectures, seminars, and experiments aboard ships and includes: Analytical and numerical analysis of ship motions and maneuvering. Hydromechanic and probabilistic modelling of water waves. Ship operability analysis with respect to seakeeping and seaworthiness. Ship motion investigations in the time domain as well as in the frequency domain where the linear responses are calculated by means of the ship’s transfer function and the sea state expressed as a wave spectrum. Characterization of stochastic processes (waves and ship response) in terms of statistical measures and extreme values. Full-scale experiment for investigating a ships roll characteristics and maneuverability.

Intended learning outcomes

This course gives opportunities to apply and deepen knowledge in mechanics, fluid mechanics, statistics and mathematics, in the modelling and evaluation of seakeeping characteristics and manoeuvrability of ships. The objective is that students after finishing the course shall be able to:

  1. investigate, evaluate and interpret a ship's roll and transversal stability characteristics and its operability with respect to seakeeping and manoeuvrability;
  2. model water waves and sea states;
  3. model ship manoeuvring and ship motions in waves;
  4. characterize the stochastic processes for ship response to waves and interpret the responses with respect to safety standards;
  5. engage and contribute in teamwork and group discussions;
  6. clearly present and discuss engineering conclusions and the knowledge and arguments behind them, orally and in writing;
  7. discuss safety, performance, economic and environmental aspects in the contex of seakeeping and manoeuvring.
