Abstract: The disclosure provides a method and system to monitor and advise the status of a group of floating platforms, such as offshore floating wind platforms, by using a floating platform's motion in the group and detect one or more anomalies to identify one or more disorders (including irregularities) in the group. Input for this method can include information of wind speed and direction and orientations of the wind turbine nacelles. The orientation of the platform can complement the orientation of a wind turbine nacelle on the platform in case the platform is equipped with a turret. Disorders include, but not limited to, mooring line failure, shifts of a drag anchor, other issues with the mooring system components such as fairleads, issues with the ballasting configuration of the floater, issues with the turret (if any), issues with the swivel of the nacelle, issues with the rotor, and issues with the blades.

Abstract: The present disclosure provides a system and method of monitoring a mooring system for a floating vessel using the time of the natural period independent of environmental conditions. The natural period can be calculated and/or established experientially over time by measuring movement of the vessel to establish the natural period at given geographical positions of a secure and intact mooring system. The natural period can be monitored based on the time to complete a natural period. A change in a mooring line stiffness, whether by a failure, stretching, a degradation of the mooring line integrity, or a significant displacement of the anchoring point, will be translated into a different natural period with a different time. By monitoring the natural period for a given geographical position (and corresponding heading) to be compared to the theoretical values (and/or previous recorded values) it is then possible to assess that at least a portion of the mooring system has failed or that a significant damage has occurred.

Abstract: The present disclosure provides a system and method for monitoring a floating vessel hull mooring system by determining one or more hull rotational motions of yaw, roll, and/or pitch that do not require independent knowledge of environmental conditions. The hull rotational motion of a secure and intact mooring system can be calculated and/or established experientially over time by measuring movement of the hull to characterize the hull rotational motion at given geographical positions. A compromised mooring system will result in different hull rotational motion of at least one of yaw, roll, and/or pitch. By monitoring the hull rotational motion for a given geographical position to be compared to the theoretical values (and/or previous recorded values), it is then possible to assess that at least a portion of the mooring system has been compromised and in at some embodiment indicate which portion of the mooring system has been compromised.

Abstract translation: 本公开提供了一种使用自然周期的时间独立于环境条件来监视浮动船只系泊系统的系统和方法。 可以通过测量船舶的运动来确定安全和完整的系泊系统的给定地理位置的自然周期，从而经验地计算和/或建立自然周期。 可以根据完成自然时期的时间对自然时期进行监测。 无论是由于故障，拉伸，系泊线完整性的退化或锚固点的显着位移，系泊线刚度的变化将被转换成具有不同时间的不同的自然周期。 通过监测要与理论值（和/或先前记录值）进行比较的给定地理位置（和相应的航向）的自然周期，则可以评估系泊系统​​的至少一部分已经失效，或者 发生重大损失。
