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.
