  • Patent number: 9725870
    Abstract: Disclosed embodiments relate to systems and methods for mating a wind turbine off-shore to a spar buoy without the use of a crane barge. The system may include a spar buoy, wherein the spar buoy is secured to a foundation, and a wind turbine to be installed on the spar buoy. The system may also include a first truss affixed to the top of the spar buoy and a second truss affixed to the bottom of the wind turbine. The first truss may comprise either stabbings or receptacles configured for mating to the second truss and the second truss may comprise either receptacles or stabbings configured for mating to the first truss.

  • Patent number: 9573659
    Abstract: A single point mooring includes a yoke-shaped articulated arm assembly, which is affixed to the seabed by a fixed foundation or mooring base assembly, and a mooring support structure, which is retrofitted to a vessel. The articulated arm is connected to the base by a triaxial articulation joint for accommodating yaw, pitch and roll. To moor the vessel, the arm is connected to the mooring support structure with weighted pendants on port and starboard sides. The pendants are suspended at an adjustable elevation with respect to the mooring support structure, thus allowing the mooring system to be used at varying water depths. A combined connection bracket hosts both pendant linkages and umbilicals or hoses for speeding the process of connecting and disconnecting a vessel from the mooring system. A removable anchor, such as a suction pile, fixes the mooring system to the seabed, allows the system to be easily redeployed to another location.
