One of the famous real-world registrations is the so-called New Year Wave recorded in the North Sea at the Draupner jacket platform on January 1, 1995. Since there is only a single point registration available, it is not possible to draw conclusions on the spatial development in front of and behind the point of registration, which is indispensable for a complete understanding of this phenomenon. This paper presents the temporal and spatial development of the New Year Wave generated in a seakeeping basin. This extreme sea state is measured at different locations in the tank, in a range from 2163 m (full scale) ahead of to 1470 m behind the target position - 520 registrations altogether. The focus lies on the detailed description of a possible evolution of the New Year Wave over a large area. The group velocity, wave propagation and energy flux of this wave group as well as the wave kinematics and dynamics are analysed. As a case study a Ro/Ro vessel has been investigated in the New Year Wave, with special emphasis on the vertical bending moment.en0029-8018201114-1516241639Wave dynamicsWave generationWave kinematicsWave propagationWave structure interactionJournal Article10.1016/j.oceaneng.2011.07.022Journal Article
