Patent ID: 8347803

Claim:
A floating roll-resistant offshore system comprising: an offshore structure having a longitudinally elongated shape with an overall longitudinal length extending from one end of the offshore structure to an opposing end thereof, a bottom of the offshore structure defining a hull baseline at a lowest point thereof; and a roll-suppression device including a pair of connection units and a pair of damping plates, each connection unit fixedly connected to the bottom of the offshore structure and configured to extend downward under the bottom of the offshore structure so that a distal end of each connection unit is below the hull baseline, and each damping plate including a plurality of plate members aligned in a longitudinal direction and connected to the distal end of a respective one of the pair of connection units to suppress rolling of the offshore structure, each damping plate separated downward from the bottom of the offshore structure entirely below the hull baseline and extending outwardly with respect to a centerline of the offshore structure, and each of the connection units and the respective damping plates extending along at least a majority of the overall longitudinal length of the offshore structure.
