Patent number: 10480258Abstract: 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.Type: GrantFiled: October 26, 2017Date of Patent: November 19, 2019Assignees: SINGLE BUOY MOORINGS, INC, GMC, LTD.Inventors: Jack Pollack, David C.

Patent number: 10260290Abstract: 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.Type: GrantFiled: October 18, 2017Date of Patent: April 16, 2019Assignee: SINGLE BUOY MOORINGS, INC.Inventors: Jack Pollack, Alpha Mahatvaraj

Patent number: 10059409Abstract: 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.Type: GrantFiled: October 6, 2015Date of Patent: August 28, 2018Assignee: Single Buoy Moorings, Inc.Inventors: Swanik Maas Hoogeveen, Jack Pollack

Patent number: 9562399Abstract: A method and apparatus for bundling flexible risers uses a vertically-hanging riser support shaft extending below the turret of a turret-moored FPSO to manage the motions of the risers. The risers may transition to a catenary configuration as they exit a bottom structure at the lower end of the riser support shaft and connect to wellheads or flowlines on the seafloor. Certain embodiments are suitable for use with a disconnectable buoyant turret mooring system while other embodiments may be used with spread-moored FPSOs.Type: GrantFiled: April 30, 2015Date of Patent: February 7, 2017Assignee: Seahourse Equipment Corp.Inventor: Jack Pollack

Patent number: 9239122Abstract: 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.Type: GrantFiled: April 5, 2013Date of Patent: January 19, 2016Assignee: Single Buoy Moorings, Inc.Inventor: Jack Pollack

Publication number: 20150321734Abstract: A floating structure includes a hull and a work structure for supporting, lifting or lowering elongate objects. The work structure includes an elevating platform having an opening for receiving an object to be supported, lifted or lowered. The elevating platform is supported on the hull and is connected to a movable force element. The work structure includes a compensator platform pivotably supported on the hull around a pivot axis via a bracket or curved track. The compensator platform has an opening for receiving the object to be handled while the elevating platform is supported on the compensator platform via at least one elastomeric support. The force element is on one side attached to the hull and on the other side to the compensator platform for transmitting a driving force or a damping force to the platform when the platform is pivoted about a pin or displaced over the curved track.Type: ApplicationFiled: December 4, 2013Publication date: November 12, 2015Applicant: Single Buoy Moorings, Inc.Inventors: Wilhelmus Coenradus Johannes Jozephus WOLDRING, Jack POLLACK, David RIGGS
