    Abstract: A method of reducing stress and wear on one or more components in a keel joint assembly in which a cobalt-based, wear resistant alloy coating is applied to the surfaces of one or more components. The use of the coating reduces stress and wear and achieves improved corrosion, galling, erosion and abrasion resistance as compared to other currently known and applied methods. In the present invention, the coating would preferably would be applied to the surfaces of the mating components of the keel joint.

    Abstract: A surface assembly that communicates with subsea structures and includes a working deck on a floating structure. The working deck has an aperture extending axially therethrough. A riser extends from a subsea location to the working deck and through the aperture. The surface assembly includes a frame extending circumferentially around the riser so that the frame moves axially with the riser. The assembly also includes a tensioner assembly connected between the working deck and the frame. The tensioner assembly includes a piston slidably carried in a piston chamber, a piston rod extending from the piston and away from the piston chamber, and a shroud enclosing the piston rod. The shroud has a plurality of segments with at least one of the shroud segments being movable in unison with the piston rod.

    Abstract: A corrosion-resistant alloy tube is formed and bonded to a pre-machined steel alloy rod to form a riser tensioner cylinder rod. During assembly, an epoxy is injected into an annular space between the tube and rod and then cured. The bonded tube is ground to a desired surface finish prior to installation and utilizes a double seal arrangement that prevents external pressure or corrosive fluids from entering the cured epoxy in the annular space.

    Abstract: The riser tensioning system (10) includes a tensioning ring (18) for secured engagement with the riser and plurality of hydraulic cylinders (12) extending between the tensioning ring and a floating platform. A gimbal mechanism (42) acts between the platform and the riser to allow the riser axis to tilt relative to the floating platform. One or more elongate torque transfer members (38) extend between the tensioning ring and the gimbal mechanism and allow axial movement of the tensioning ring and the riser with respect to the floating platform.

    Abstract: A riser tensioner has inner and outer cylindrical barrels that telescopingly engage each other. A small external tank is mounted outside of the barrels for communicating a small quantity of hydraulic fluid the seals between the inner and outer barrels. The external tank allows the internal volume of the cylinder rod assembly to be used for gas storage and reduces the need for accumulators. The fluid level in the external tank is checked via a sight glass, and the tank is isolated from the cylinder assembly by a combination of check and three-way valves, which allows easier access to the working fluid, and allows the addition or removal of high pressure fluid to the system without a high pressure fluid cart.

    Abstract: A riser tensioner cylinder rod incorporates a thin, corrosion-resistant alloy tube over a pre-machined steel alloy rod. The tube is swedged at one end and expanded to the inner surface of a split die. A gradual tapered surface on a stretching die provides a smooth transition during a stretching process for the tube. A pressurizing vessel traps an outer lip of the pre-swedged tube. Pressurized fluid in the vessel simultaneously causes the tube to expand and force the rod into the tube inner diameter. At the completion of the process, the pressurizing vessel is removed. The stretched tube is parted off at both ends and the stretching die is removed from the rod to complete the assembly.
