Course*  Offshore Hydromechanics II
Offshore Hydromechanics includes the following modules: 1. Hydrostatics, static floating stability, constant 2D potential flow of ideal fluids, and flows in real fluids. Introduction to resistance and propulsion of ships. Review of linear regular and irregular wave theory. 2. Analytical and numerical means to determine the flow around, forces on, and motions of floating bodies in waves. 3. Higher order potential theory and inclusion of nonlinear effects in ship motions. Applications to motion of moored ships and to the determination of workability. 4. Interaction between the sea and sea bottom as well as the hydrodynamic forces and especially survival loads on slender structures. Study Goals: Participants who have successfully completed the course will be able to carry out computations at a superior knowledge level involving: Module 1 (2 cr): Hydrostatics, floating stability and 2D potential flows, as well as regular and irregular waves and their spectra. Module 2 (2 cr): Computations relevant for first order forces on and resulting motions of ships. Module 3 (2 cr): Nonlinear forces on and resulting ships motions; workability prediction. Module 4 (2 cr): Hydrodynamic forces on slender structures including marine pipelines. In addition, successful participants completing module 1 will have a basic awareness of ship propulsion systems and their computations. Those completing module 4 will have an advanced knowledge of sea bed morphology.
