Rogue waves are extraordinarily large waves in the ocean, which are widely recognized as great threats to human's oceanic activities. To better understand their effects on marine structures, it is necessary to generate rogue waves, which has similar features as reality, in laboratory or numerical wave tank. To reproduce its unique features, several methods for generating rogue waves are proposed. The most commonly used approaches include NewWave, focusing wave and Peregrine breather, which are all adopted in extensive researches in this area. Nevertheless, the differences between them have not been studied quantitatively. This paper presents a numerical investigation of the rogue waves simulated in a numerical wave tank based on a fully nonlinear potential theory. Quantitative discussions on the differences between the rogue waves generated by different approaches are carried out.
