Abstract:
The formation of extreme ocean waves, sometimes termed 'rogue waves', poses a risk to offshore structures. In this talk, I will discuss some characteristics of extreme ocean waves with a focus on nonlinear mechanics. I will briefly explain the governing equations and demonstrate the significance of the nonlinear terms using numerical simulation results. My analysis shows that directional energy transfers, due to nonlinear interactions, can significantly alter the shape, lifespan and kinematics of an extreme wave event with implications for engineering design.

Dylan Barratt is currently completing a DPhil degree (10/2017-present) in the Department of Engineering Science at the University of Oxford, UK. Before arriving at Oxford, he was employed as a scientific assistant (07/2015-09/2017) at ETH Zurich, Switzerland. He obtained an MSc in mechanical engineering (09/2013-07/2015) from Seoul National University, Korea. He also holds a BSc in mechanical engineering (01/2009-12/2012) from the University of the Witwatersrand, South Africa, receiving the William John Walker Gold Medal as the top graduate in the department.
