Main specialisation

3. Marine Hydrodynamics

Illustrasjonsbilde/FOTOThe focus of the Marine Hydrodynamics profile  includes the discipline hydrodynamics itself and/or its application on marine operations or subsea engineering. The profile options may also be combined with courses from the other profiles Marine structural engineering or Marine cybernetics.

Keywords: Sea loads, oceanography, ship hydrodynamics, marine operations, subsea engineering/technology.

Learning knowledge and skills of Marine hydrodynamics
 

Marine hydrodynamics is about flow around marine structures, such as ships, various types of offshore structures, fish farming plants, and structures for renewable offshore energy. Waves, wave induced motions and wave loads, as well as resistance and propulsion of ships are important topics.
 

Knowledge

The candidate shall, after completion of this study profile, have:
• Insight in critical aspects of marine structures, critical response variables and criteria related to safety and operations.
• Good knowledge about environmental effects like wind, waves and current, as well as motion characteristics, natural periods, resonance and instability.
• Have good understanding of the physics of phenomena relevant for current-structure interaction problems.
• Have good understanding of the kinematics and dynamics of surface waves.
• Understand the fundamentals of wave force son structures and how they can be determined.
• Understand the difference between turbulent and laminar flow, the influence it has on the flow pattern around structures and in the wake of marine structures, as well as the resulting forces on the structures.
• Understand the physics of flow resistance on ships and other marine structures.
• Understand the principles of lift on foils and other bodies.
• Understand the working principles of propellers and various types of propulsion systems.
• Understand what cavitation is, what causes it, and its importance for performance of propellers, foils, rudders, and the like.
• Have and overview of various marine structures, ship types, and propeller types and their particular hydrodynamic properties.
 

Skills

The student shall be able to:
• Perform calculations involving linear surface waves
• Perform calculations of wave motions and loads on ships and offshore structures using computer programs.
• Compute natural periods of motion of floating structures.
• To be able to use simple methods in an early design phase in relation to planning of marine operations or control of computer simulations or model tests.
• Compute resistance and required propulsion power of ships in calm water and in waves.
• To do correct choice of main dimensions of a propeller for a given task.
