Fluid Mechanics and Loading on Marine Structures

The course aims to give delegates the tools to manage problems of structures-fluid interactions. A theoretical background on basic fluid mechanics is given, followed by a focus on aerodynamic and hydrodynamic loading on structures, particularly offshore and sub-sea. It also aims to present the dynamics of floating bodies, from simple hydrostatics to complex dynamic response in waves.
