Information on properties of ocean waves, such as wave height, period, direction and others, is important for design of marine and coastal structures, for other engineering and safety issues. One of the most important issues in this regard is related to extreme wave events. In the thesis we presented analysis of long-term wave simulations performed using a numerical scheme based on solving three-dimensional potential equations in deep water. A set of features and statistics are investigated. The emergence of coherent structures on the ocean surface, closely related to the tendency of high waves to occur in groups, is analysed.
