  • Publication number: 20210339831
    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.

  • Patent number: 9671231
    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.

  • Patent number: 7690866
    Abstract: An offshore oil-drilling rig comprising a deck mounted mobile on legs, each leg including a support base on the sea floor and a caisson open at its base and designed to penetrate into the sea floor. Each caisson is arranged inside the leg and is mobile along the axis of the leg between a retracted upper position and a projecting lower position at which it is anchored on the sea floor. The invention also concerns methods for installing such a rig on an oil-drilling site.
