最近发生的小型渔船在破碎波中的事故使海军设计师们对极端波浪的动力学产生了浓厚的兴趣。在海洋工程领域，当计算破碎波作用在近海结构物构件上的力时，对于使用什么样的速度和加速度也缺乏了解。然而，一般来说，它们只对对称的行波有效。Longuet-Higgins和Cokelet（Longuet-Higgins and Cokelet 1976，Cokelet 1978）发展了一种求解周期二维深水破碎波问题的数值方法。该方法是基于势理论和保角映射的物理平面内的一个封闭的轮廓在映射的平面，并在这个平面上的运动方程求解。然后，通过映射的反演来找到物理平面中的波形。有关数值技术和时间积分程序的详细信息可在参考文献中找到。
Recent accidents with smaller fishing vessels in breaking waves have focused the interest of naval architects on the dynamics of extreme waves. In the field of ocean engineering there is also a lack of knowledge about what velocities and accelerations to use when calculating the forces from breaking waves on structural members of offshore structures.A number of theories for steady, finite amplitude surface waves are available. In general they are, however, only valid for symmetric, progressive waves. Longuet-Higgins and Cokelet (Longuet-Higgins and Cokelet 1976, Cokelet 1978) have developed a numerical technique for solving the periodic, 2-dimensional, deep water breaking wave problem. This method is based on potential theory and a conformal mapping of the physical plane inside a closed contour in the mapped plane, and the equations of motion are solved in this plane. Then the wave form in the physical plane is found by an inversion of the mapping. Details about the numerical techniques and the time integration procedures are found in the references.
