Few sights are as fascinating as that of a huge wave breaking onto the shore or slamming into a breakwater in stormy weather. Beautiful as they are, such waves present a major challenge to the offshore, coastal and marine industries where their brutal forces can cause fatal damage on structures and vessels. Today our limited ability to measure and model the kinematics in breaking and near-breaking waves necessitates the addition of large uncertainty factors e.g. in the design of offshore wind turbine foundations [1] and oil & gas infrastructure. This directly affects the cost of energy. Guidelines and best practices in the offshore sector[2] incorporate the currently available wave knowledge. But observations of large breaking waves near coastal and offshore installations indicate that current guide lines may not be sufficiently conservative. Hence a better understanding of the formation and breaking process of large ocean waves and improved ability to calculate the forces they inflict on marine structures are highly needed in order to secure and optimize future offshore and coastal structural designs. With recent advances in numerical methods and the ever larger computer power, CFD is approaching a level of maturity where it can become a powerful tool both in the offshore structural design phase and in fundamental wave dynamics research. Within the field of free surface CFD modelling there remains, however, a number of problems which this project will attempt to solve. The vision is to develop a research and engineering tool able to simulate ocean wave breaking and structural impact with unprecedented speed, detail and fidelity. The primary societal perspectives are safer marine infrastructure and lower cost of energy. In terms of future research the scientific perspective is the ability to foster new insights into the dynamics of highly nonlinear waves in complex physical water environments.
