波浪引起的运动限制了许多海上作业的工作时间和安全性，例如起重机升降、LNG输送和直升机着陆。本文详细介绍了最近的努力，确定性地预测海洋表面波从WaMoS II的测量。WaMoS II从航海X波段雷达图像中获得完整的三维海面高程图，为有用的预测地平线提供足够的分辨率和范围。这些表面高程场的验证表明，它们与来自波浪浮标和运动参考单元的海面高程时间序列非常一致。从一个简单的传播模型的结果。
Wave induced motions limit the working time and safety of many offshore operations, e.g. crane lifts, LNG transfers, and helicopter landings. This paper details recent efforts to deterministically predict ocean surface waves using measurements from the WaMoS II. The WaMoS II derives full 3-dimensional sea surface elevation maps from nautical X-band radar images, yielding both sufficient resolution and range for a useful prediction horizon. Validation of these surface elevation fields shows they are in close agreement with sea surface elevation timeseries from wave buoys and motion reference units. Results from a simple propagation model are presented.
