    Abstract: Methods that may be employed to help to equalize the length of the teeth on a pin-and-box SCR connector during make-up include locating the make-up groove on the box at the far box end away from the pipe end. This causes the make-up force to tension and stretch the box to make it longer. Additionally or alternatively placing grease or other fluid in the nib groove creates a resistance force to nib entry. The grease or fluid exits through a nib vent port in the box while creating a resistance that compresses the pin and stretches the box causing the tooth spacing of the pin and the box to be similar. Providing a ring groove at both ends of the box allows a tensioning device to be used to tension the box causing box elongation, which equalizes the tooth length of pin and box members during connector make up.

    Abstract: In a pipe joint where two pipe sections (14, 16) have threadably engaged end potions (17, 18), joint ends (32, 34) are substantially sealed to each other by a sealing surface (40, 50) on one pipe section that substantially abuts a sealing surface (42, 52) on the other pipe section. In one joint, a ring-shaped cutout(121, FIG. 7) is formed in a first pipe section and a ring-shaped spacer (120) is located in the cutout. The spacer is chosen from several that have slightly different lengths so the spacer ends contacts the corresponding sealing surface(130).

    Abstract: A Taut-Inverted-Catenary (TIC) mooring system may be implemented using only field-proven components. The mooring lines yield a positive uplift force on the anchors in all conditions. In the inverted-catenary configuration, geometric stiffness is provided by a subsurface spring buoy or distributed buoyancy elements on the line. The TIC system consists as much as possible of light-weight components, such as polyester fiber rope. Since the uplift force on the anchor is always positive, clearance between polyester rope and the seabed is provided. All geometric stiffness is provided by the spring buoy. Therefore, a ground chain between the seafloor anchor and the fiber rope is not necessary.

    Abstract: In a pipe joint where two pipe sections (14, 16) have threadably engaged end portions (17, 18), joint ends (32, 34) are substantially sealed to each other by a sealing surface (40, 50) on one pipe section that substantially abuts a sealing surface (42, 52) on the other pipe section. In one joint, a ring-shaped cutout (121, FIG. 7) is formed in a first pipe section and a ring-shaped spacer (120) is located in the cutout. The spacer is chosen from several that have slightly different lengths so the spacer end contacts the corresponding sealing surface (130). In a pipe string used to carry corrosive fluid, the inner surface (44) of adjacent pipe sections is covered with a corrosion resistant coating (70, 72). Where the sealing surface is connected to a rounded corner (82, 84), the coating extends to and along the sealing surfaces (40, 42). Where there are sharp corners (80) at the intersection of the inside surface (40) with the sealing surface (40B, 42B), the coating does not extend along the sealing surfaces.

    Abstract: A pipeline includes a pair of pipe sections with ends (20, 22), connected together by threads. the pipe ends having axial and radial abutments lying beyond the ends of the thread. The abutments are located to stabilize a nib sealing arrangement and to enhance the capacity to resist bending while using a shorter thread length. The shorter threads (24, 26) enable pipe ends of smaller wall thicknesses to be used. At the abutments, each pipe end has a nib (40A, 40B) that is deflected to enter a groove as the pipe ends mate.
