Wave Interactions with Offshore Systems

Catalog description

Wave energy converters, offshore wind turbines, liquified natural gas (LNG) vessels, and autonomous underwater vehicles are some examples of offshore systems that are affected by ocean waves. This course presents the analytical framework to analyze the interactions these types of systems and ambient ocean waves. We begin by discussing surface wave theory and properties of regular surface waves and random ocean waves. We then discuss the linearized theory of floating body dynamics along with kinematic and dynamic free surface conditions and body boundary conditions that arise in the ocean setting. We consider simple harmonic motions and both diffraction and radiation problems of waves. We derive key hydrodynamic coefficients of offshore systems such as added mass, damping, and stiffness. Finally, we discuss ship seakeeping in regular and random waves. Throughout the course, examples and homework problems are drawn from real-world applications such as offshore wind turbines.
