Abstract: Offshore wind turbine systems and processes for installing same. The system can include a wind turbine generator that can include a plurality of blades connected thereto. The system can also include a first support arm and a second support arm each having a first end and a second end. The system can also include a support structure that can be configured to float on a surface of a body of water that can include first, second, and third columns. The first end of the first support arm and the first end of the second support arm can each support the wind turbine generator at an elevation above the support structure. The second end of the first support arm can be connected to and supported by the first column. The second end of the second support arm can be connected to and supported by the second column.

Abstract: Yoke mooring systems and processes for using same. The system can include a turntable connected to and rotatable with respect to a base. A yoke can be connected to the turntable such that the yoke can at least partially rotate about a longitudinal axis of the yoke and at least partially rotate about a second axis that can be orthogonal to the longitudinal axis. A first and second link arm can be connected to the yoke and to a first component of a first and a second releasable connector, respectively. A first and second lifting line can be connected to the second end of the first and second link arms, respectively. A first and second lifting device can be disposed on a vessel and configured to be connected to a second end of the first and second lifting lines, respectively, to lift and lower the link arms and the yoke.

Abstract: A disconnectable mooring system for connecting an LNG carrier vessel to a permanently moored LNG liquefaction process vessel in combination with an LNG offloading system. One end of a mooring yoke is suspended from a frame at the stern of the LNG process vessel. A male coupler is mounted to an opposite end of the mooring yoke via a universal joint. A female coupler is mounted on the LNG carrier vessel, with pull-in arrangements for pulling the LNG carrier vessel into position and the male coupler into selective coupling with the female coupler.

Abstract: An arrangement for providing fluid communication between an offshore hydrocarbon production and/or storage facility and an offshore loading system such as a CALM buoy is disclosed. A pipeline from a FPSO or production platform runs to a submerged flowline termination buoy which is positioned beneath and separated a short distance from a CALM buoy. The flowline termination buoy is separately anchored to the sea bed from the CALM buoy, and is at a depth below the turbulent zone of the sea. The end of the pipeline is suspended from the flowline termination buoy, and a marine hose fluidly connects the end of the pipeline to a stationary part of a fluid swivel on the CALM buoy. The arrangement isolates the end of the pipeline from fatigue inducing motions of the CALM buoy.

Abstract: A method and apparatus for replacing an existing looped non-metallic mooring line (20) from a floating anchor handling vessel (10) anchored to the sea floor. The existing looped line (20) extends about a sheave (34) adjacent a subsea anchor means (24) and opposed ends (26) of the looped line (20) are connected to a mounting member (30) on the vessel (10) for securing the ends (26) of the existing mooring line (20). The new replacement line (20A) is attached to an end of the looped existing line (20) and the old existing line (20) is hauled in while the looped replacement line (20A) is payed out from the vessel (10) about the sheave (34) for return to the vessel. The looped replacement line (20A) is disconnected from the old line (20) and the ends of the new replacement line (20A) are secured to a mounting member (30) on the vessel.

Abstract: A disconnectable vessel mooring system including a storage vessel (10) with a turret (32) mounted therein so that the vessel is free to weathervane about an anchored turret. A spider buoy (44) in a docked position is received within the turret (32) with the upper part of the buoy at a position above the sea water level to permit dry servicing of the buoy (44). Anchor legs (68) in the docked position are secured to the turret (32) by securing means (71). Guide tubes (72) on the outer surface of the buoy (44) receive the anchor legs (68) therein for limited longitudinal travel. Selected anchor legs (68) may be disconnected from the buoy (44) when detached from the turret (32) for lowering onto the sea floor to reduce the weight of anchor legs supported by the buoy (44).
