Naval Architecture and Ship Hydrodynamics

• Brief introduction to Naval Architecture
• Resistance and propulsion of ships
• General linear dynamic theory
• Wave theory (regular and irregular waves)

• Wave loads
• Wave-induced motion of ships
• Sea-keeping, motion-criteria and operability
• Offshore lifting operations
• Slamming loads and response to impulsive loads

• Non-linear wave loads, wave drift forces
• Station-keeping in waves
• Manoeuvring of ships

Knowledge

• Have thorough knowledge of the various resistance components for a ship and the principles for applying model tests to estimate the resistance of a full scale ship;
• Have thorough knowledge on how propellers work and how they can provide thrust to a ship;
• Have thorough knowledge of how to model regular waves and how this can be extended to model irregular waves
• Have good knowledge of how to use statistical methods to predict estimates of extremes
• Have thorough knowledge of how to analyse vessel motions

• Have good knowledge of how to analyse offshore lifting operations, and how to calculate the various hydrodynamic loads involved in this analysis
• Have good knowledge of the background for the nonlinear forces (wave drift forces) and how the station-keeping systems work to account for these;
• Have thorough knowledge of how to assess a ships maneuvering capabilities (standard menuver tests)

Skills

• Can analyse and interpret results from resistance and propulsion tests and use them to predict the relevant full-scale information for a ship;

• Can use statistical methods to predict the probability that the vessel response exceeds a given threshold;
• Can use relevant computer programs (e.g. SHIPX) to analyse ship motions in waves and use the results to assess the operability of a certain ship;
• Can use relevant computer programs to analyse the station-keeping and maneuverability capabilities of a ship

General competence

• Can analyse relevant hydrodynamic problems and select the proper scientific methods to predict the expected behavior;

• Can apply his/her knowledge on new related problems to carry out relevant projects;
• Will be familiar with the terminology used in relevant academic and professional discussion os sea-keeping and maneuvering of a vessel;
• Can communicate effectively about hydrodynamic problems and analysis results with both specialists and to the general public;
• Can contribute to new thinking and in work effectively in a multidisciplinary engineering team.

Teaching methods: Class room lectures, homework, mandatory assignments and a project report. 3/4 of the assignments and the project report must be accepted.
