Online Hydrodynamics Training Course

About The Course

This course is expected to be of great help to professionals in major ports, harbours, offshore and
marine industries. The course will facilitate to understand the terminology pertaining to the study of
wave mechanics and will give an insight into the different types of structures in the ocean front and the physical and environmental parameters prevailing on the ocean surfaces. The basics of wave motion and wave deformation, which is the central interest and major focus. A notable account on small amplitude wave theory followed by profound explanation and inferences of dynamic properties of standing and progressive waves will be discussed. A detailed summary of the various types of wave deformations along with their degree of importance in near-shore environment and influence of wave parameters will be discussed. A detailed account of finite amplitude wave theory with mathematical and statistical approach highlighting the established theories will be discussed
in detail. The real-time environment for an actual sea state consisting of random waves, which is nonperiodic and nonlinear in nature will be discussed. Further, the impact of wave loads on structures and energy from ocean waves will be discussed in detail.

Who Should Attend?

Engineers and scientists involved in the design of ships and ship systems. Personnel from ship management companies, oil companies, classification societies and ship builders will benefit from attending this course. The course is innovative in both content & structure with a careful balance of theory & practice.
