Abstract: A floating wind turbine farm 230 includes a plurality of anchors 20/202/204/206/208 fixed in or on a bed of a body of water. A plurality of floating wind turbine platforms 10 is deployed in the body of water, each of the floating wind turbine platforms 10 having one or more mooring lines 200/212 that extend between, and are attached to, the floating wind turbine platform 10 and one of the anchors 20/202/204/206/208. Each anchor 20/202/204/206/208 is configured to receive two or more mooring lines 200/212, wherein each of the mooring lines 200/212 are from a different one of the plurality of floating wind turbine platforms 10.

Abstract: A flexible connection for use between a vertical, large diameter cold water conveying pipe and a floating platform that supports the cold water conveying pipe or another pipe to permit the pipe and the platform to rotate in roll and pitch directions relative to one another without imposing excessive bending moments or strain on the cold water pipe. The flexible connection also contains internal and external pressure across the connection. The flexible connection includes an articulation mechanism that interconnects the vertical cold water conveying pipe and the platform or a pipe on the platform, and a flexible, fluid impermeable bellows.

Abstract: An undersea anchor that includes a frame that is fixed to the seafloor by one or more pile anchors, for example grouted pile anchors. The frame is configured to permit it to function with one or more seabed drills to allow the pile anchor(s) to be installed at an angle relative to horizontal so the pile anchors can take horizontal and vertical loads.

Abstract: A floating support that can be joined with a floating platform while the floating platform is at a deployment location is disclosed. The support provides functionality to the floating platform in order to change, augment, upgrade, or diversify the platform's overall capability. In some embodiments, the present invention eases the serviceability of the platform by enabling a first support that has diminished capability to be readily replaced by a second support having superior capability—without removing the floating platform from its deployment location. In some embodiments, the present invention enables platform operation that is analogous to “plug and play” electronics systems. Further, in some embodiments, hydrodynamic performance of the floating platform can be changed with the addition or removal of one or more floating supports.

Abstract: A floating offshore drilling/producing structure. The structure is formed from a plurality of closely spaced vertically oriented buoyant columns on which one or more modules or decks may be placed to support process equipment, a drilling rig, utilities, and accommodations for personnel. The columns are held in the spaced relationship by a plurality of horizontal plates spaced along the length of the columns and vertical plates located near the bottom of the columns and near the top of the columns. Drilling and/or producing is accomplished through risers located approximately in the center of the structure. The structure includes fixed ballast, an oil storage area, and voids and variable ballast for offsetting the lighter weight of the stored oil. The columns have a smaller water plane area than the horizontal plates.
