Potentially extremely dangerous realistic rogue waves – also called as freak waves – can now be controlled and generated at will in laboratory environments, in similar conditions as they appear in the ocean.
In a study, models – breather solutions of the nonlinear Schrödinger equation – have been validated in an experimental environment, water wave tanks. These breathers describe the dynamics of unstable water waves that become rogue: the instability arise from a calm state. As a result, now we know how rogue waves may appear in realistic oceanic conditions.
This will help us not only to predict oceanic extreme events, but also in the design of safer ships and offshore rigs. In fact, newly designed vessels and rig model prototypes can be tested to encounter in a small scale, before they are built, realistic extreme ocean waves. Therefore, initial plans may change, if models are not resistant enough to face suddenly occurring freak waves.
