各种类型的海上作业的可操作性在很大程度上受到波浪和波浪引起的运动的影响。例如，从船员转移船或服务操作船向海上风力涡轮机转移船员以进行维护、直升机在（海军）船舶中着陆以及各种起重机操作。近年来，已经在技术上投入了相当多的努力，旨在提前几分钟提供对接近的波浪和波浪引起的船舶运动的真实的实时船上预测。使船员能够预见，从而提高这些操作的安全性和可操作性。本文讨论了该系统的现场测试过程中的性能，正在开发的下一个海洋，使这种预测，基于使用现成的（非相干）导航雷达系统作为远程波观测。简要总结（早期出版物）的技术方法，重点将是从现场测试中获得的结果，该系统进行了验证。在一艘42米长的巡逻船上，在荷兰海岸附近的北海进行的一次现场试验中，由船上运动参考装置测量的船舶运动与由波浪和运动预测系统获得的预测之间的良好一致性将在结果部分中显示出来，从中可以得出该系统用于业务决策支持的有用性的结论。
The workability of various types of operations offshore are largely affected by waves and wave induced motions. Examples are crew transfer from crew transfer vessels or service operation vessels to offshore wind turbines for maintenance, landing of helicopters in (navy) vessels and various crane operations. Over the recent years quite some effort has been put in technology aiming to provide a real time on-board prediction of approaching waves and wave induced vessel motions some minutes in advance. Enabling crew to anticipate, thus enhancing the safety and operability of these operations. This paper addresses the performance during a field test of the system as being under development by Next Ocean enabling such predictions, based on using an off-the-shelve (non-coherent) navigation radar system as a remote wave observer. Briefly summarizing (earlier publications on) the technical approach, focus will be on results obtained from a field test where the system was validated. Good agreements between ship motions as measured by an on-board motion reference unit and predictions obtained by the wave and motion prediction system during a field test on the North Sea near the Dutch coast on a 42 m patrol vessel will be shown in the results section, from which the usefulness of the system for operational decision support can be concluded.
